+# QMK Breaking Change - 2019 Aug 30
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+This document marks the inaugural Breaking Change merge. A list of changes follows.
+
+## Core code formatting with clang-format
+
+* All core files (`drivers/`, `quantum/`, `tests/`, and `tmk_core/`) have been formatted with clang-format
+* A travis process to reformat PR's on merge has been instituted
+* You can use the new CLI command `qmk cformat` to format before submitting your PR if you wish.
+
+## LUFA USB descriptor cleanup
+
+* Some code cleanups related to the USB HID descriptors on AVR keyboards, to make them easier to read and understand
+* More information: see https://github.com/qmk/qmk_firmware/pull/4871
+* No behaviour changes anticipated and no keymaps modified
+
+## Migrating `ACTION_LAYER_MOMENTARY()` entries in `fn_actions` to `MO()` keycodes
+
+* `fn_actions` is deprecated, and its functionality has been superseded by direct keycodes and `process_record_user()`
+* The end result of removing this obsolete feature should result in a decent reduction in firmware size and code complexity
+* All keymaps affected are recommended to switch away from `fn_actions` in favour of the [custom keycode](https://docs.qmk.fm/#/custom_quantum_functions) and [macro](https://docs.qmk.fm/#/feature_macros) features
+
+## Update Atreus to current code conventions
+
+* Duplicate include guards have bypassed the expected header processing behavior
+* All keymaps affected are recommended to remove duplication of `<keyboard>/config.h` to `<keyboard>/keymaps/<user>/config.h` and only provide overrides at the keymap level
+
+## Backport changes to keymap language files from ZSA fork
+
+* Fixes an issue in the `keymap_br_abnt2.h` file that includes the wrong source (`keymap_common.h` instead of `keymap.h`)
+* Updates the `keymap_swedish.h` file to be specific to swedish, and not just "nordic" in general. 
+* Any keymaps using this will need to remove `NO_*` and replace it with `SE_*`. 
+
+## Update repo to use LUFA as a git submodule
+
+* `/lib/LUFA` removed from the repo
+* LUFA set as a submodule, pointing to qmk/lufa
+* This should allow more flexibility with LUFA, and allow us to keep the sub-module up to date, a lot more easily.  It was ~2 years out of date with no easy path to fix that.  This prevents that from being an issue in the future
+  
+## Migrating `ACTION_BACKLIGHT_*()` entries in `fn_actions` to `BL_` keycodes
+
+* `fn_actions` is deprecated, and its functionality has been superseded by direct keycodes and `process_record_user()`
+* All keymaps using these actions have had the relevant `KC_FN*` keys replaced with the equivalent `BL_*` keys
+* If you currently use `KC_FN*` you will need to replace `fn_actions` with the [custom keycode](https://docs.qmk.fm/#/custom_quantum_functions) and [macro](https://docs.qmk.fm/#/feature_macros) features
+
+## Remove `KC_DELT` alias in favor of `KC_DEL`
+
+* `KC_DELT` was a redundant, undocumented alias for `KC_DELETE`
+* It has been removed and all its uses replaced with the more common `KC_DEL` alias
+* Around 90 keymaps (mostly for ErgoDox boards) have been modified as a result

+# Breaking Changes
+
+This document describes QMK's Breaking Change process. A Breaking Change is any change which modifies how QMK behaves in a way that in incompatible or potentially dangerous. We limit these changes so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+The breaking change period is when we will merge PR's that change QMK in dangerous or unexpected ways. There is a built-in period of testing so we are confident that any problems caused are rare or unable to be predicted.
+
+## What has been included in past Breaking Changes?
+
+* [2019 Aug 30](ChangeLog/20190830.md)
+
+## When is the next Breaking Change?
+
+The next Breaking Change is scheduled for Nov 29.
+
+### Important Dates
+
+* [ ] 2019 Oct 04 - `future` is created. It will be rebased weekly.
+* [ ] 2019 Nov 01 - `future` closed to new PR's.
+* [ ] 2019 Nov 01 - Call for testers.
+* [ ] 2019 Nov 27 - `master` is locked, no PR's merged.
+* [ ] 2019 Nov 29 - Merge `future` to `master`.
+* [ ] 2019 Nov 30 - `master` is unlocked. PR's can be merged again.
+
+## What changes will be included?
+
+To see a list of breaking change candidates you can look at the [`breaking_change` label](https://github.com/qmk/qmk_firmware/pulls?q=is%3Aopen+label%3Abreaking_change+is%3Apr). New changes might be added between now and when `future` is closed, and a PR with that label applied is not guaranteed to be merged.
+
+If you want your breaking change to be included in this round you need to create a PR with the `breaking_change` label and have it accepted before `future` closes. After `future` closes no new breaking changes will be accepted.
+
+Criteria for acceptance:
+
+* PR is complete and ready to merge
+* PR has a ChangeLog
+
+# Checklists
+
+This section documents various processes we use when running the Breaking Changes process.
+
+## Rebase `future` from `master`
+
+This is run every Friday while `future` is open.
+
+Process:
+
+```
+cd qmk_firmware
+git checkout master
+git pull --ff-only
+git checkout future

+# QMK CLI
+
+This page describes how to setup and use the QMK CLI.
+
+# Overview
+
+The QMK CLI makes building and working with QMK keyboards easier. We have provided a number of commands to help you work with QMK:
+
+* `qmk compile`
+* `qmk doctor`
+
+# Setup
+
+Simply add the `qmk_firmware/bin` directory to your `PATH`. You can run the `qmk` commands from any directory.
+
+```
+export PATH=$PATH:$HOME/qmk_firmware/bin
+```
+
+You may want to add this to your `.profile`, `.bash_profile`, `.zsh_profile`, or other shell startup scripts.
+
+# Commands
+
+## `qmk compile`
+
+This command allows you to compile firmware from any directory. You can compile JSON exports from <https://config.qmk.fm> or compile keymaps in the repo.
+
+**Usage for Configurator Exports**:
+
+```
+qmk compile <configuratorExport.json>
+```
+
+**Usage for Keymaps**:
+
+```
+qmk compile -kb <keyboard_name> -km <keymap_name>
+```
+
+## `qmk cformat`
+
+This command formats C code using clang-format. Run it with no arguments to format all core code, or pass filenames on the command line to run it on specific files.
+
+**Usage**:
+
+```
+qmk cformat [file1] [file2] [...] [fileN]
+```

+# Coding Conventions (C)
+
+Most of our style is pretty easy to pick up on, but right now it's not entirely consistent. You should match the style of the code surrounding your change, but if that code is inconsistent or unclear use the following guidelines:
+
+* We indent using four (4) spaces (soft tabs)
+* We use a modified One True Brace Style
+  * Opening Brace: At the end of the same line as the statement that opens the block
+  * Closing Brace: Lined up with the first character of the statement that opens the block
+  * Else If: Place the closing brace at the beginning of the line and the next opening brace at the end of the same line.
+  * Optional Braces: Always include optional braces.
+    * Good: if (condition) { return false; }
+    * Bad: if (condition) return false;
+* We encourage use of C style comments: `/* */`
+  * Think of them as a story describing the feature
+  * Use them liberally to explain why particular decisions were made.
+  * Do not write obvious comments
+  * If you not sure if a comment is obvious, go ahead and include it.
+* In general we don't wrap lines, they can be as long as needed. If you do choose to wrap lines please do not wrap any wider than 76 columns.
+* We use `#pragma once` at the start of header files rather than old-style include guards (`#ifndef THIS_FILE_H`, `#define THIS_FILE_H`, ..., `#endif`)
+* We accept both forms of preprocessor if's: `#ifdef DEFINED` and `#if defined(DEFINED)`
+  * If you are not sure which to prefer use the `#if defined(DEFINED)` form.
+  * Do not change existing code from one style to the other, except when moving to a multiple condition `#if`.
+  * Do not put whitespace between `#` and `if`.
+  * When deciding how (or if) to indent directives keep these points in mind:
+    * Readability is more important than consistency.
+    * Follow the file's existing style. If the file is mixed follow the style that makes sense for the section you are modifying.
+    * When choosing to indent you can follow the indention level of the surrounding C code, or preprocessor directives can have their own indent level. Choose the style that best communicates the intent of your code.
+
+Here is an example for easy reference:
+
+```c
+/* Enums for foo */
+enum foo_state {
+  FOO_BAR,
+  FOO_BAZ,
+};
+
+/* Returns a value */
+int foo(void) {
+  if (some_condition) {
+    return FOO_BAR;
+  } else {
+    return -1;
+  }
+}
+```
+
+# Auto-formatting with clang-format
+
+[Clang-format](https://clang.llvm.org/docs/ClangFormat.html) is part of LLVM and can automatically format your code for you, because ain't nobody got time to do it manually. We supply a configuration file for it that applies most of the coding conventions listed above. It will only change whitespace and newlines, so you will still have to remember to include optional braces yourself.
+
+Use the [full LLVM installer](http://llvm.org/builds/) to get clang-format on Windows, or use `sudo apt install clang-format` on Ubuntu.
+
+If you run it from the command-line, pass `-style=file` as an option and it will automatically find the .clang-format configuration file in the QMK root directory.
+
+If you use VSCode, the standard C/C++ plugin supports clang-format, alternatively there is a [separate extension](https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.ClangFormat) for it.
+
+Some things (like LAYOUT macros) are destroyed by clang-format, so either don't run it on those files, or wrap the sensitive code in `// clang-format off` and `// clang-format on`.

+# Coding Conventions (Python)
+
+Most of our style follows PEP8 with some local modifications to make things less nit-picky. 
+
+* We target Python 3.5 for compatability with all supported platforms.
+* We indent using four (4) spaces (soft tabs)
+* We encourage liberal use of comments
+  * Think of them as a story describing the feature
+  * Use them liberally to explain why particular decisions were made.
+  * Do not write obvious comments
+  * If you not sure if a comment is obvious, go ahead and include it.
+* We require useful docstrings for all functions.
+* In general we don't wrap lines, they can be as long as needed. If you do choose to wrap lines please do not wrap any wider than 76 columns.
+* Some of our practices conflict with the wider python community to make our codebase more approachable to non-pythonistas.
+
+# YAPF
+
+You can use [yapf](https://github.com/google/yapf) to style your code. We provide a config in [setup.cfg](setup.cfg).
+
+# Imports
+
+We don't have a hard and fast rule for when to use `import ...` vs `from ... import ...`. Understandability and maintainability is our ultimate goal.
+
+Generally we prefer to import specific function and class names from a module to keep code shorter and easier to understand. Sometimes this results in a name that is ambiguous, and in such cases we prefer to import the module instead. You should avoid using the "as" keyword when importing, unless you are importing a compatability module.
+
+Imports should be one line per module. We group import statements together using the standard python rules- system, 3rd party, local.
+
+Do not use `from foo import *`. Supply a list of objects you want to import instead, or import the whole module.
+
+## Import Examples
+
+Good:
+
+```
+from qmk import effects
+
+effects.echo()
+```
+
+Bad:
+
+```
+from qmk.effects import echo
+
+echo()  # It's unclear where echo comes from
+```
+
+Good:
+
+```
+from qmk.keymap import compile_firmware
+
+compile_firmware()
+```
+
+OK, but the above is better:
+
+```
+import qmk.keymap
+
+qmk.keymap.compile_firmware()
+```
+
+# Statements
+
+One statement per line.
+
+Even when allowed (EG `if foo: bar`) we do not combine 2 statements onto a single line.
+
+# Naming
+
+`module_name`, `package_name`, `ClassName`, `method_name`, `ExceptionName`, `function_name`, `GLOBAL_CONSTANT_NAME`, `global_var_name`, `instance_var_name`, `function_parameter_name`, `local_var_name`.
+
+Function names, variable names, and filenames should be descriptive; eschew abbreviation. In particular, do not use abbreviations that are ambiguous or unfamiliar to readers outside your project, and do not abbreviate by deleting letters within a word.
+
+Always use a .py filename extension. Never use dashes.
+
+## Names to Avoid
+
+* single character names except for counters or iterators. You may use "e" as an exception identifier in try/except statements.
+* dashes (-) in any package/module name
+* __double_leading_and_trailing_underscore__ names (reserved by Python)
+
+# Docstrings
+
+To maintain consistency with our docstrings we've set out the following guidelines.
+
+* Use markdown formatting
+* Always use triple-dquote docstrings with at least one linebreak: `"""\n"""`
+* First line is a short (< 70 char) description of what the function does
+* If you need more in your docstring leave a blank line between the description and the rest.
+* Start indented lines at the same indent level as the opening triple-dquote
+* Document all function arguments using the format described below
+* If present, Args:, Returns:, and Raises: should be the last three things in the docstring, separated by a blank line each.
+
+## Simple docstring example
+
+```
+def my_awesome_function():
+    """Return the number of seconds since 1970 Jan 1 00:00 UTC.
+    """
+    return int(time.time())
+```
+
+## Complex docstring example
+
+```
+def my_awesome_function():
+    """Return the number of seconds since 1970 Jan 1 00:00 UTC.
+
+    This function always returns an integer number of seconds.
+    """
+    return int(time.time())
+```
+
+## Function arguments docstring example
+
+```
+def my_awesome_function(start=None, offset=0):
+    """Return the number of seconds since 1970 Jan 1 00:00 UTC.
+
+    This function always returns an integer number of seconds.
+
+
+    Args:
+        start
+            The time to start at instead of 1970 Jan 1 00:00 UTC
+
+        offset
+            Return an answer that has this number of seconds subtracted first
+
+    Returns:
+        An integer describing a number of seconds.
+
+    Raises:
+        ValueError
+            When `start` or `offset` are not positive numbers
+    """
+    if start < 0 or offset < 0:
+        raise ValueError('start and offset must be positive numbers.')
+
+    if not start:
+        start = time.time()
+
+    return int(start - offset)
+```
+
+# Exceptions
+
+Exceptions are used to handle exceptional situations. They should not be used for flow control. This is a break from the python norm of "ask for forgiveness." If you are catching an exception it should be to handle a situation that is unusual.
+
+If you use a catch-all exception for any reason you must log the exception and stacktrace using cli.log.
+
+Make your try/except blocks as short as possible. If you need a lot of try statements you may need to restructure your code.
+
+# Tuples
+
+When defining one-item tuples always include a trailing comma so that it is obvious you are using a tuple. Do not rely on implicit one-item tuple unpacking. Better still use a list which is unambiguous.
+
+This is particularly important when using the printf-style format strings that are commonly used.
+
+# Lists and Dictionaries
+
+We have configured YAPF to differentiate between sequence styles with a trailing comma. When a trailing comma is omitted YAPF will format the sequence as a single line. When a trailing comma is included YAPF will format the sequence with one item per line.
+
+You should generally prefer to keep short definition on a single line. Break out to multiple lines sooner rather than later to aid readability and maintainability.
+
+# Parentheses
+
+Avoid excessive parentheses, but do use parentheses to make code easier to understand. Do not use them in return statements unless you are explicitly returning a tuple, or it is part of a math expression.
+
+# Format Strings
+
+We generally prefer printf-style format strings. Example:
+
+```
+name = 'World'
+print('Hello, %s!' % (name,))
+```
+
+This style is used by the logging module, which we make use of extensively, and we have adopted it in other places for consistency. It is also more familiar to C programmers, who are a big part of our casual audience.
+
+Our included CLI module has support for using these without using the percent (%) operator. Look at `cli.echo()` and the various `cli.log` functions (EG, `cli.log.info()`) for more details.
+
+# Comprehensions & Generator Expressions
+
+We encourage the liberal use of comprehensions and generators, but do not let them get too complex. If you need complexity fall back to a for loop that is easier to understand.
+
+# Lambdas
+
+OK to use but probably should be avoided. With comprehensions and generators the need for lambdas is not as strong as it once was.
+
+# Conditional Expressions
+
+OK in variable assignment, but otherwise should be avoided.
+
+Conditional expressions are if statements that are in line with code. For example:
+
+```
+x = 1 if cond else 2
+```
+
+It's generally not a good idea to use these as function arguments, sequence items, etc. It's too easy to overlook.
+
+# Default Argument Values
+
+Encouraged, but values must be immutable objects.
+
+When specifying default values in argument lists always be careful to specify objects that can't be modified in place. If you use a mutable object the changes you make will persist between calls, which is usually not what you want. Even if that is what you intend to do it is confusing for others and will hinder understanding.
+
+Bad:
+
+```
+def my_func(foo={}):
+    pass
+```
+
+Good:
+
+```
+def my_func(foo=None):
+    if not foo:
+        foo = {}
+```
+
+# Properties
+
+Always use properties instead of getter and setter functions.
+
+```
+class Foo(object):
+    def __init__(self):
+        self._bar = None
+
+    @property
+    def bar(self):
+        return self._bar
+
+    @bar.setter
+    def bar(self, bar):
+        self._bar = bar
+```
+
+# True/False Evaluations
+
+You should generally prefer the implicit True/False evaluation in if statements, rather than checking equivalency.
+
+Bad:
+
+```
+if foo == True:
+    pass
+
+if bar == False:
+    pass
+```
+
+Good:
+
+```
+if foo:
+    pass

+# Decorators
+
+Use when appropriate. Try to avoid too much magic unless it helps with understanding.
+
+# Threading and Multiprocessing
+
+Should be avoided. If you need this you will have to make a strong case before we merge your code.
+
+# Power Features
+
+Python is an extremely flexible language and gives you many fancy features such as custom metaclasses, access to bytecode, on-the-fly compilation, dynamic inheritance, object reparenting, import hacks, reflection, modification of system internals, etc.
+
+Don't use these.
+
+Performance is not a critical concern for us, and code understandability is. We want our codebase to be approachable by someone who only has a day or two to play with it. These features generally come with a cost to easy understanding, and we would prefer to have code that can be readily understood over faster or more compact code.
+
+Note that some standard library modules use these techniques and it is ok to make use of those modules. But please keep readability and understandability in mind when using them.
+
+# Type Annotated Code
+
+For now we are not using any type annotation system, and would prefer that code remain unannotated. We may revisit this in the future.
+
+# Function length
+
+Prefer small and focused functions.
+
+We recognize that long functions are sometimes appropriate, so no hard limit is placed on function length. If a function exceeds about 40 lines, think about whether it can be broken up without harming the structure of the program.
+
+Even if your long function works perfectly now, someone modifying it in a few months may add new behavior. This could result in bugs that are hard to find. Keeping your functions short and simple makes it easier for other people to read and modify your code.
+
+You could find long and complicated functions when working with some code. Do not be intimidated by modifying existing code: if working with such a function proves to be difficult, you find that errors are hard to debug, or you want to use a piece of it in several different contexts, consider breaking up the function into smaller and more manageable pieces.
+
+# FIXMEs
+
+It is OK to leave FIXMEs in code. Why? Encouraging people to at least document parts of code that need to be thought out more (or that are confusing) is better than leaving this code undocumented.
+
+All FIXMEs should be formatted like:
+
+```
+FIXME(username): Revisit this code when the frob feature is done.
+```
+
+...where username is your GitHub username.

 # Coding Conventions
 
-Most of our style is pretty easy to pick up on, but right now it's not entirely consistent. You should match the style of the code surrounding your change, but if that code is inconsistent or unclear use the following guidelines:
+Most of our style is pretty easy to pick up on. If you are familiar with either C or Python you should not have too much trouble with our local styles.
 
-* We indent using four (4) spaces (soft tabs)
-* We use a modified One True Brace Style
-  * Opening Brace: At the end of the same line as the statement that opens the block
-  * Closing Brace: Lined up with the first character of the statement that opens the block
-  * Else If: Place the closing brace at the beginning of the line and the next opening brace at the end of the same line.
-  * Optional Braces: Always include optional braces.
-    * Good: if (condition) { return false; }
-    * Bad: if (condition) return false;
-* We encourage use of C style comments: `/* */`
-  * Think of them as a story describing the feature
-  * Use them liberally to explain why particular decisions were made.
-  * Do not write obvious comments
-  * If you not sure if a comment is obvious, go ahead and include it.
-* In general we don't wrap lines, they can be as long as needed. If you do choose to wrap lines please do not wrap any wider than 76 columns.
-* We use `#pragma once` at the start of header files rather than old-style include guards (`#ifndef THIS_FILE_H`, `#define THIS_FILE_H`, ..., `#endif`)
-* We accept both forms of preprocessor if's: `#ifdef DEFINED` and `#if defined(DEFINED)`
-  * If you are not sure which to prefer use the `#if defined(DEFINED)` form.
-  * Do not change existing code from one style to the other, except when moving to a multiple condition `#if`.
-  * Do not put whitespace between `#` and `if`.
-  * When deciding how (or if) to indent directives keep these points in mind:
-    * Readability is more important than consistency.
-    * Follow the file's existing style. If the file is mixed follow the style that makes sense for the section you are modifying.
-    * When choosing to indent you can follow the indention level of the surrounding C code, or preprocessor directives can have their own indent level. Choose the style that best communicates the intent of your code.
-
-Here is an example for easy reference:
-
-```c
-/* Enums for foo */
-enum foo_state {
-  FOO_BAR,
-  FOO_BAZ,
-};
-
-/* Returns a value */
-int foo(void) {

-# Auto-formatting with clang-format
-
-[Clang-format](https://clang.llvm.org/docs/ClangFormat.html) is part of LLVM and can automatically format your code for you, because ain't nobody got time to do it manually. We supply a configuration file for it that applies most of the coding conventions listed above. It will only change whitespace and newlines, so you will still have to remember to include optional braces yourself.
-
-Use the [full LLVM installer](http://llvm.org/builds/) to get clang-format on Windows, or use `sudo apt install clang-format` on Ubuntu.
-
-If you run it from the command-line, pass `-style=file` as an option and it will automatically find the .clang-format configuration file in the QMK root directory.
-
-If you use VSCode, the standard C/C++ plugin supports clang-format, alternatively there is a [separate extension](https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.ClangFormat) for it.
-
-Some things (like LAYOUT macros) are destroyed by clang-format, so either don't run it on those files, or wrap the sensitive code in `// clang-format off` and `// clang-format on`.

+# Bootloader Driver Installation with Zadig
+
+QMK presents itself to the host as a regular HID keyboard device, and as such requires no special drivers. However, in order to flash your keyboard on Windows, the bootloader device that appears when you reset the board often *does*.
+
+There are two notable exceptions: the Caterina bootloader, usually seen on Pro Micros, and the Halfkay bootloader shipped with PJRC Teensys, appear as a serial port and a generic HID device respectively, and so do not require a driver.
+
+We recommend the use of the [Zadig](https://zadig.akeo.ie/) utility. If you have set up the development environment with Msys2 or WSL, the `qmk_install.sh` script will have asked if you want it to install the drivers for you.
+
+## Installation
+
+Place your keyboard into the bootloader mode, either by hitting the `RESET` keycode (which may be on a different layer), or by pressing the reset switch usually located on the underside of the board. If your keyboard has neither, try holding Escape, or Space+`B`, as you plug it in (see the [Bootmagic](feature_bootmagic.md) docs for more details).
+Some keyboards may have specific instructions for entering the bootloader, for example the [Bootmagic Lite](feature_bootmagic.md#bootmagic-lite) key (Escape) might be on a different key, such as Left Control. Refer to the board's README if you are unsure.
+
+Zadig will automatically detect the bootloader device. You may sometimes need to check **Options -> List All Devices**.
+ - For keyboards with Atmel AVR MCUs, the bootloader will be named something similar to `ATm32U4DFU`, and have a Vendor ID of `03EB`.
+ - USBasp bootloaders will appear as `USBasp`, with a VID/PID of `16C0:05DC`.
+ - AVR keyboards flashed with the QMK-DFU bootloader will be named `<keyboard name> Bootloader` and will also have the VID `03EB`.
+ - For most ARM keyboards, it will be called `STM32 BOOTLOADER`, and have a VID/PID of `0483:DF11`.
+
+!> If Zadig lists one or more devices with the `HidUsb` driver, your keyboard is probably not in bootloader mode. The arrow will be colored orange and you will be asked to confirm modifying a system driver. **Do not** proceed if this is the case!
+
+If the arrow appears green, select the driver, and click **Install Driver**. The `libusb-win32` driver will usually work for AVR, and `WinUSB` for ARM, but if you still cannot flash the board, try installing a different driver from the list.
+
+![Zadig with a bootloader driver correctly installed](https://i.imgur.com/b8VgXzx.png)
+
+Finally, unplug and replug the keyboard to make sure the new driver has been loaded. If you are using the QMK Toolbox to flash, exit and restart it too, as it can sometimes fail to recognize the driver change.
+
+## Recovering from Installation to Wrong Device
+
+If you find that you can no longer type with the keyboard, you may have installed the driver onto the keyboard itself instead of the bootloader. You can easily confirm this in Zadig - a healthy keyboard has the `HidUsb` driver installed on all of its interfaces:
+
+![A healthy keyboard as seen by Zadig](https://i.imgur.com/Hx0E5kC.png)
+
+Open the Device Manager and look for a device that looks like your keyboard.
+
+![The board with the wrong driver installed, in Device Manager](https://i.imgur.com/L3wvX8f.png)
+
+Right-click it and hit **Uninstall device**. Make sure to tick **Delete the driver software for this device** first.
+
+![The Device Uninstall dialog, with the "delete driver" checkbox ticked](https://i.imgur.com/aEs2RuA.png)
+
+Click **Action -> Scan for hardware changes**. At this point, you should be able to type again. Double check in Zadig that the keyboard device(s) are using the `HidUsb` driver. If so, you're all done, and your board should be functional again!

 ## Unknown Device for DFU Bootloader
 
-If you're using Windows to flash your keyboard, and you are running into issues, check the Device Manager.  If you see an "Unknown Device" when the keyboard is in "bootloader mode", then you may have a driver issue.
+Issues encountered when flashing keyboards on Windows are most often due to having the wrong drivers installed for the bootloader, or none at all.
 
-Re-running the installation script for MSYS2 may help (eg run `./util/qmk_install.sh` from MSYS2/WSL) or reinstalling the QMK Toolbox may fix the issue.
-
-If that doesn't work, then you may need to grab the [Zadig Utility](https://zadig.akeo.ie/). Download this, find the device in question, and select the `WinUSB` option, and hit "Reinstall driver". Once you've done that, try flashing your board, again.  If that doesn't work, try all of the options, until one works. 
-
-?> There isn't a best option for which driver should be used here.  Some options work better on some systems than others.  libUSB and WinUSB seem to be the best options here.
-
-If the bootloader doesn't show up in the list for devices, you may need to enable the "List all devices" option in the `Options` menu, and then find the bootloader in question. 
+Re-running the QMK installation script (`./util/qmk_install.sh` from the `qmk_firmware` directory in MSYS2 or WSL) or reinstalling the QMK Toolbox may fix the issue. Alternatively, you can download and run the [`qmk_driver_installer`](https://github.com/qmk/qmk_driver_installer) package manually.

-When all timers are in use for [audio](feature_audio.md), the backlight software PWM will not use a hardware timer, but instead will be triggered during the matrix scan. In this case the backlight doesn't support breathing and might show lighting artifacts (for instance flickering), because the PWM computation might not be called with enough timing precision.

+## Backlight On State
+
+Most backlight circuits are driven by an N-channel MOSFET or NPN transistor. This means that to turn the transistor *on* and light the LEDs, you must drive the backlight pin, connected to the gate or base, *high*.
+Sometimes, however, a P-channel MOSFET, or a PNP transistor is used. In this case, when the transistor is on, the pin is driven *low* instead.
+
+This functionality is configured at the keyboard level with the `BACKLIGHT_ON_STATE` define.

If your split keyboard uses I2C to communicate between sides, this driver could cause an address conflict (serial is fine). Please contact your keyboard vendor and ask them to migrate to the latest split common code to fix this. In addition, the display timeout system to reduce OLED burn-in also uses split common to detect keypresses, so you will need to implement custom timeout logic for non-split common keyboards.

-The first part, `// Key Matrix to LED Index`, tells the system what key this LED represents by using the key's electrical matrix row & col. The second part, `// LED Index to Physical Position` represents the LED's physical position on the keyboard. The first value, `x`, is between 0-224 (inclusive), and the second value, `y`, is between 0-64 (inclusive). This range is due to effect that calculate the center or halves for their animations. The easiest way to calculate these positions is imagine your keyboard is a grid, and the top left of the keyboard represents x, y coordinate 0, 0 and the bottom right of your keyboard represents 224, 64. Using this as a basis, you can use the following formula to calculate the physical position:
+The first part, `// Key Matrix to LED Index`, tells the system what key this LED represents by using the key's electrical matrix row & col. The second part, `// LED Index to Physical Position` represents the LED's physical `{ x, y }` position on the keyboard. The default expected range of values for `{ x, y }` is the inclusive range `{ 0..224, 0..64 }`. This default expected range is due to effects that calculate the center of the keyboard for their animations. The easiest way to calculate these positions is imagine your keyboard is a grid, and the top left of the keyboard represents `{ x, y }` coordinate `{ 0, 0 }` and the bottom right of your keyboard represents `{ 224, 64 }`. Using this as a basis, you can use the following formula to calculate the physical position:
 
 ```C
 x = 224 / (NUMBER_OF_COLS - 1) * COL_POSITION
 y =  64 / (NUMBER_OF_ROWS - 1) * ROW_POSITION
 ```

+Where NUMBER_OF_COLS, NUMBER_OF_ROWS, COL_POSITION, & ROW_POSITION are all based on the physical layout of your keyboard, not the electrical layout. 
+
+As mentioned earlier, the center of the keyboard by default is expected to be `{ 112, 32 }`, but this can be changed if you want to more accurately calculate the LED's physical `{ x, y }` positions. Keyboard designers can implement `#define RGB_MATRIX_CENTER { 112, 32 }` in their config.h file with the new center point of the keyboard, or where they want it to be allowing more possibilities for the `{ x, y }` values. Do note that the maximum value for x or y is 255, and the recommended maximum is 224 as this gives animations runoff room before they reset.
 
 `// LED Index to Flag` is a bitmask, whether or not a certain LEDs is of a certain type. It is recommended that LEDs are set to only 1 type.

 If your keyboard lacks onboard underglow LEDs, you may often be able to solder on an RGB LED strip yourself. You will need to find an unused pin to wire to the data pin of your LED strip. Some keyboards may break out unused pins from the MCU to make soldering easier. The other two pins, VCC and GND, must also be connected to the appropriate power pins.

+# Split Keyboard 
+
+Many keyboards in the QMK Firmware repo are "split" keyboards. They use two controllers—one plugging into USB, and the second connected by a serial or an I<sup>2</sup>C connection over a TRRS or similar cable. 
+
+Split keyboards can have a lot of benefits, but there is some additional work needed to get them enabled.  
+
+QMK Firmware has a generic implementation that is usable by any board, as well as numerous board specific implementations. 
+
+For this, we will mostly be talking about the generic implementation used by the Let's Split and other keyboards. 
+
+!> ARM is not yet supported for Split Keyboards.  Progress is being made, but we are not quite there, yet. 
+
+
+## Hardware Configuration
+
+This assumes that you're using two Pro Micro-compatible controllers, and are using TRRS jacks to connect to two halves. 
+
+### Required Hardware
+
+Apart from diodes and key switches for the keyboard matrix in each half, you will need 2x TRRS sockets and 1x TRRS cable.
+
+Alternatively, you can use any sort of cable and socket that has at least 3 wires. 
+
+If you want to use I<sup>2</sup>C to communicate between halves, you will need a cable with at least 4 wires and 2x 4.7kΩ pull-up resistors.
+
+#### Considerations 
+
+The most commonly used connection is a TRRS cable and jacks.  These provide 4 wires, making them very useful for split keyboards, and are easy to find. 
+
+However, since one of the wires carries VCC, this means that the boards are not hot pluggable. You should always disconnect the board from USB before unplugging and plugging in TRRS cables, or you can short the controller, or worse. 
+
+Another option is to use phone cables (as in, old school RJ-11/RJ-14 cables). Make sure that you use one that actually supports 4 wires/lanes.  
+
+However, USB cables, SATA cables, and even just 4 wires have been known to be used for communication between the controllers. 
+
+!> Using USB cables for communication between the controllers works just fine, but the connector could be mistaken for a normal USB connection and potentially short out the keyboard, depending on how it's wired.  For this reason, they are not recommended for connecting split keyboards.  
+
+### Serial Wiring
+
+The 3 wires of the TRS/TRRS cable need to connect GND, VCC, and D0 (aka PDO or pin 3) between the two Pro Micros. 
+
+?> Note that the pin used here is actually set by `SOFT_SERIAL_PIN` below.
+
+![serial wiring](https://i.imgur.com/C3D1GAQ.png)
+
+### I<sup>2</sup>C Wiring
+
+The 4 wires of the TRRS cable need to connect GND, VCC, and SCL and SDA (aka PD0/pin 3 and PD1/pin 2, respectively) between the two Pro Micros. 
+
+The pull-up resistors may be placed on either half. It is also possible to use 4 resistors and have the pull-ups in both halves, but this is unnecessary in simple use cases.
+
+![I2C wiring](https://i.imgur.com/Hbzhc6E.png)
+
+## Firmware Configuration
+
+To enable the split keyboard feature, add the following to your `rules.mk`: 
+
+```make
+SPLIT_KEYBOARD = yes
+```
+
+If you're using a custom transport (communication method), then you will also need to add: 
+
+```make
+SPLIT_TRANSPORT = custom
+```
+
+### Setting Handedness
+
+By default, the firmware does not know which side is which; it needs some help to determine that. There are several ways to do this, listed in order of precedence.
+
+#### Handedness by Pin
+
+You can configure the firmware to read a pin on the controller to determine handedness.  To do this, add the following to your `config.h` file:
+
+```c
+#define SPLIT_HAND_PIN B7
+```
+
+This will read the specified pin. If it's high, then the controller assumes it is the left hand, and if it's low, it's assumed to be the right side. 
+
+#### Handedness by EEPROM
+
+This method sets the keyboard's handedness by setting a flag in the persistent storage (`EEPROM`).  This is checked when the controller first starts up, and determines what half the keyboard is, and how to orient the keyboard layout. 
+
+
+To enable this method, add the following to your `config.h` file: 
+
+```c
+#define EE_HANDS
+```
+
+However, you'll have to flash the EEPROM files for the correct hand to each controller.  You can do this manually, or there are targets for avrdude and dfu to do this, while flashing the firmware: 
+
+* `:avrdude-split-left`
+* `:avrdude-split-right`
+* `:dfu-split-left`
+* `:dfu-split-right`
+
+This setting is not changed when re-initializing the EEPROM using the `EEP_RST` key, or using the `eeconfig_init()` function.  However, if you reset the EEPROM outside of the firmware's built in options (such as flashing a file that overwrites the `EEPROM`, like how the [QMK Toolbox]()'s "Reset EEPROM" button works), you'll need to re-flash the controller with the `EEPROM` files. 
+
+You can find the `EEPROM` files in the QMK firmware repo, [here](https://github.com/qmk/qmk_firmware/tree/master/quantum/split_common). 
+
+#### Handedness by `#define`
+
+You can set the handedness at compile time.  This is done by adding the following to your `config.h` file:
+
+```c
+#define MASTER_RIGHT
+```
+
+or 
+
+```c
+#define MASTER_LEFT
+```
+
+If neither are defined, the handedness defaults to `MASTER_LEFT`.
+
+
+### Communication Options
+
+Because not every split keyboard is identical, there are a number of additional options that can be configured in your `config.h` file.
+
+```c
+#define USE_I2C
+```
+
+This enables I<sup>2</sup>C support for split keyboards. This isn't strictly for communication, but can be used for OLED or other I<sup>2</sup>C-based devices. 
+
+```c
+#define SOFT_SERIAL_PIN D0
+```
+
+This sets the pin to be used for serial communication. If you're not using serial, you shouldn't need to define this.  
+
+However, if you are using serial and I<sup>2</sup>C on the board, you will need to set this, and to something other than D0 and D1 (as these are used for I<sup>2</sup>C communication).
+
+```c
+#define SELECT_SOFT_SERIAL_SPEED {#}`
+```
+
+If you're having issues with serial communication, you can change this value, as it controls the communication speed for serial.  The default is 1, and the possible values are:
+
+* **`0`**: about 189kbps (Experimental only)
+* **`1`**: about 137kbps (default)
+* **`2`**: about 75kbps
+* **`3`**: about 39kbps
+* **`4`**: about 26kbps
+* **`5`**: about 20kbps
+
+###  Hardware Configuration Options
+
+There are some settings that you may need to configure, based on how the hardware is set up. 
+
+```c
+#define MATRIX_ROW_PINS_RIGHT { <row pins> }
+#define MATRIX_COL_PINS_RIGHT { <col pins> }
+```
+
+This allows you to specify a different set of pins for the matrix on the right side.  This is useful if you have a board with differently-shaped halves that requires a different configuration (such as Keebio's Quefrency).
+
+```c
+#define DIRECT_PINS_RIGHT { { F1, F0, B0, C7 }, { F4, F5, F6, F7 } }
+```
+
+This allows you to specify a different set of direct pins for the right side.
+
+```c
+#define ENCODERS_PAD_A_RIGHT { encoder1a, encoder2a }
+#define ENCODERS_PAD_B_RIGHT { encoder1b, encoder2b }
+```
+
+This allows you to specify a different set of encoder pins for the right side.
+
+```c
+#define RGBLIGHT_SPLIT
+```
+
+This option enables synchronization of the RGB Light modes between the controllers of the split keyboard.  This is for keyboards that have RGB LEDs that are directly wired to the controller (that is, they are not using the "extra data" option on the TRRS cable).
+
+```c
+#define RGBLED_SPLIT { 6, 6 }
+```
+
+This sets how many LEDs are directly connected to each controller.  The first number is the left side, and the second number is the right side.  
+
+?> This setting implies that `RGBLIGHT_SPLIT` is enabled, and will forcibly enable it, if it's not.
+
+
+## Additional Resources
+
+Nicinabox has a [very nice and detailed guide](https://github.com/nicinabox/lets-split-guide) for the Let's Split keyboard, that covers most everything you need to know, including troubleshooting information. 
+
+However, the RGB Light section is out of date, as it was written long before the RGB Split code was added to QMK Firmware. Instead, wire each strip up directly to the controller.

 # Tap Dance: A Single Key Can Do 3, 5, or 100 Different Things
 
-<!-- FIXME: Break this up into multiple sections -->
-
+## Introduction
 Hit the semicolon key once, send a semicolon. Hit it twice, rapidly -- send a colon. Hit it three times, and your keyboard's LEDs do a wild dance. That's just one example of what Tap Dance can do. It's one of the nicest community-contributed features in the firmware, conceived and created by [algernon](https://github.com/algernon) in [#451](https://github.com/qmk/qmk_firmware/pull/451). Here's how algernon describes the feature:
 
 With this feature one can specify keys that behave differently, based on the amount of times they have been tapped, and when interrupted, they get handled before the interrupter.
 
-To make it clear how this is different from `ACTION_FUNCTION_TAP`, let's explore a certain setup! We want one key to send `Space` on single tap, but `Enter` on double-tap.
+## Explanatory Comparison with `ACTION_FUNCTION_TAP`
+`ACTION_FUNCTION_TAP` can offer similar functionality to Tap Dance, but it's worth noting some important differences. To do this, let's explore a certain setup! We want one key to send `Space` on single-tap, but `Enter` on double-tap.
 
-With `ACTION_FUNCTION_TAP`, it is quite a rain-dance to set this up, and has the problem that when the sequence is interrupted, the interrupting key will be sent first. Thus, `SPC a` will result in `a SPC` being sent, if they are typed within `TAPPING_TERM`. With the tap dance feature, that'll come out as `SPC a`, correctly.

Thus, `SPC a` will result in `a SPC` being sent, if `SPC` and `a` are both typed within `TAPPING_TERM`. With the Tap Dance feature, that'll come out correctly as `SPC a` (even if both `SPC` and `a` are typed within the `TAPPING_TERM`.
 
-The implementation hooks into two parts of the system, to achieve this: into `process_record_quantum()`, and the matrix scan. We need the latter to be able to time out a tap sequence even when a key is not being pressed, so `SPC` alone will time out and register after `TAPPING_TERM` time.

That way, `SPC` alone will time out and register after `TAPPING_TERM` time.
 
-But lets start with how to use it, first!
+## How to Use Tap Dance
+But enough of the generalities; lets look at how to actually use Tap Dance!
 
-First, you will need `TAP_DANCE_ENABLE=yes` in your `rules.mk`, because the feature is disabled by default. This adds a little less than 1k to the firmware size. Next, you will want to define some tap-dance keys, which is easiest to do with the `TD()` macro, that - similar to `F()`, takes a number, which will later be used as an index into the `tap_dance_actions` array.

-This array specifies what actions shall be taken when a tap-dance key is in action. Currently, there are five possible options:
+Optionally, you might want to set a custom `TAPPING_TERM` time by adding something like this in you `config.h`:
+
+```
+#define TAPPING_TERM 175
+```
+
+The `TAPPING_TERM` time is the maximum time allowed between taps of your Tap Dance key, and is measured in milliseconds. For example, if you used the above `#define` statement and set up a Tap Dance key that sends `Space` on single-tap and `Enter` on double-tap, then this key will send `ENT` only if you tap this key twice in less than 175ms. If you tap the key, wait more than 175ms, and tap the key again you'll end up sending `SPC SPC` instead. 
+
+Next, you will want to define some tap-dance keys, which is easiest to do with the `TD()` macro, that - similar to `F()` - takes a number, which will later be used as an index into the `tap_dance_actions` array. 
+
+After this, you'll want to use the `tap_dance_actions` array to specify what actions shall be taken when a tap-dance key is in action. Currently, there are five possible options:
 
 * `ACTION_TAP_DANCE_DOUBLE(kc1, kc2)`: Sends the `kc1` keycode when tapped once, `kc2` otherwise. When the key is held, the appropriate keycode is registered: `kc1` when pressed and held, `kc2` when tapped once, then pressed and held.
 * `ACTION_TAP_DANCE_DUAL_ROLE(kc, layer)`: Sends the `kc` keycode when tapped once, or moves to `layer`. (this functions like the `TO` layer keycode).
@@ -24,17 +35,22 @@ This array specifies what actions shall be taken when a tap-dance key is in acti
 * `ACTION_TAP_DANCE_FN_ADVANCED(on_each_tap_fn, on_dance_finished_fn, on_dance_reset_fn)`: Calls the first specified function - defined in the user keymap - on every tap, the second function when the dance action finishes (like the previous option), and the last function when the tap dance action resets.
 * `ACTION_TAP_DANCE_FN_ADVANCED_TIME(on_each_tap_fn, on_dance_finished_fn, on_dance_reset_fn, tap_specific_tapping_term)`: This functions identically to the `ACTION_TAP_DANCE_FN_ADVANCED` function, but uses a custom tapping term for it, instead of the predefined `TAPPING_TERM`.
 
-The first option is enough for a lot of cases, that just want dual roles. For example, `ACTION_TAP_DANCE_DOUBLE(KC_SPC, KC_ENT)` will result in `Space` being sent on single-tap, `Enter` otherwise.

This function checks whether the key pressed is a tap-dance key. If it is not, and a tap-dance was in action, we handle that first, and enqueue the newly pressed key. If it is a tap-dance key, then we check if it is the same as the already active one (if there's one active, that is). If it is not, we fire off the old one first, then register the new one. If it was the same, we increment the counter and the timer.
+Finally, the fifth option is particularly useful if your non-Tap-Dance keys start behaving weirdly after adding the code for your Tap Dance keys. The likely problem is that you changed the `TAPPING_TERM` time to make your Tap Dance keys easier for you to use, and that this has changed the way your other keys handle interrupts.
 
-This means that you have `TAPPING_TERM` time to tap the key again, you do not have to input all the taps within that timeframe. This allows for longer tap counts, with minimal impact on responsiveness.
+## Implementation Details

 Wrap each tapdance keycode in `TD()` when including it in your keymap, e.g. `TD(ALT_LP)`.
+
+### Example 6: Using tap dance for momentary-layer-switch and layer-toggle keys
+
+Tap Dance can be used to mimic MO(layer) and TG(layer) functionality. For this example, we will set up a key to function as `KC_QUOT` on single-tap, as `MO(_MY_LAYER)` on single-hold, and `TG(_MY_LAYER)` on double-tap.
+
+The first step is to include the following code towards the beginning of your `keymap.c`:
+
+```
+typedef struct {
+  bool is_press_action;
+  int state;
+} tap;
+
+//Define a type for as many tap dance states as you need
+enum {
+  SINGLE_TAP = 1,
+  SINGLE_HOLD = 2,
+  DOUBLE_TAP = 3
+};
+
+enum {
+  QUOT_LAYR = 0     //Our custom tap dance key; add any other tap dance keys to this enum 
+};
+
+//Declare the functions to be used with your tap dance key(s)
+
+//Function associated with all tap dances
+int cur_dance (qk_tap_dance_state_t *state);
+
+//Functions associated with individual tap dances
+void ql_finished (qk_tap_dance_state_t *state, void *user_data);
+void ql_reset (qk_tap_dance_state_t *state, void *user_data);
+
+//Declare variable to track which layer is active
+int active_layer;
+```
+
+The above code is similar to that used in previous examples. The one point to note is that you need to declare a variable to keep track of what layer is currently the active layer. We'll see why shortly.
+
+Towards the bottom of your `keymap.c`, include the following code:
+
+```
+//Update active_layer
+uint32_t layer_state_set_user(uint32_t state) {
+  switch (biton32(state)) {
+    case 1:
+      active_layer = 1;
+      break;
+    case 2:
+      active_layer = 2;
+      break;
+    case 3:
+      active_layer = 3;
+      break;
+    default:
+      active_layer = 0;
+      break;
+  }
+  return state;
+}
+
+//Determine the current tap dance state
+int cur_dance (qk_tap_dance_state_t *state) {
+  if (state->count == 1) {
+    if (!state->pressed) {return SINGLE_TAP;}
+    else return SINGLE_HOLD;
+  } else if (state->count == 2) {return DOUBLE_TAP;}
+  else return 8;
+}
+
+//Initialize tap structure associated with example tap dance key
+static tap ql_tap_state = {
+  .is_press_action = true,
+  .state = 0
+};
+
+//Functions that control what our tap dance key does
+void ql_finished (qk_tap_dance_state_t *state, void *user_data) {
+  ql_tap_state.state = cur_dance(state);
+  switch (ql_tap_state.state) {
+    case SINGLE_TAP: tap_code(KC_QUOT); break;
+    case SINGLE_HOLD: layer_on(_MY_LAYER); break;
+    case DOUBLE_TAP: 
+      if (active_layer==_MY_LAYER) {layer_off(_MY_LAYER);}
+      else layer_on(_MY_LAYER);
+  }
+}
+
+void ql_reset (qk_tap_dance_state_t *state, void *user_data) {
+  if (ql_tap_state.state==SINGLE_HOLD) {layer_off(_MY_LAYER);}
+  ql_tap_state.state = 0;
+}
+
+//Associate our tap dance key with its functionality
+qk_tap_dance_action_t tap_dance_actions[] = {
+  [QUOT_LAYR] = ACTION_TAP_DANCE_FN_ADVANCED_TIME(NULL, ql_finished, ql_reset, 275)
+};
+```
+
+The is where the real logic of our tap dance key gets worked out. Since `layer_state_set_user()` is called on any layer switch, we use it to update `active_layer`. Our example is assuming that your `keymap.c` includes 4 layers, so adjust the switch statement here to fit your actual number of layers.
+
+The use of `cur_dance()` and `ql_tap_state` mirrors the above examples.
+
+The `case:SINGLE_TAP` in `ql_finished` is similar to the above examples. The `case:SINGLE_HOLD` works in conjunction with `ql_reset()` to switch to `_MY_LAYER` while the tap dance key is held, and to switch away from `_MY_LAYER` when the key is released. This mirrors the use of `MO(_MY_LAYER)`. The `case:DOUBLE_TAP` works by checking whether `_MY_LAYER` is the active layer, and toggling it on or off accordingly. This mirrors the use of `TG(_MY_LAYER)`.
+
+`tap_dance_actions[]` works similar to the above examples. Note that I used `ACTION_TAP_DANCE_FN_ADVANCED_TIME()` instead of `ACTION_TAP_DANCE_FN_ADVANCED()`. This is because I like my `TAPPING_TERM` to be short (~175ms) for my non-tap-dance keys but find that this is too quick for me to reliably complete tap dance actions - thus the increased time of 275ms here.
+
+Finally, to get this tap dance key working, be sure to include `TD(QUOT_LAYR)` in your `keymaps[]`.

+This is most useful when creating a keymap for an international layout with special characters. Instead of having to put the lower and upper case versions of a character on separate keys, you can have them both on the same key by using `XP()`. This helps blend Unicode keys in with regular alphas.
 
 Due to keycode size constraints, _i_ and _j_ can each only refer to one of the first 128 characters in your `unicode_map`. In other words, 0 ≤ _i_ ≤ 127 and 0 ≤ _j_ ≤ 127. This is enough for most use cases, but if you'd like to customize the index calculation, you can override the [`unicodemap_index()`](https://github.com/qmk/qmk_firmware/blob/71f640d47ee12c862c798e1f56392853c7b1c1a8/quantum/process_keycode/process_unicodemap.c#L40) function.

+
+### Windows
+1. Download [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash).
+2. Place your keyboard into reset. 
+3. Ensure the configured VendorID is `16c0` and ProductID is `05df`
+4. Press the `Find Device` button and ensure that your keyboard is found.
+5. Press the `Open .hex File` button and locate the `.hex` file you created.
+6. Press the `Flash Device` button and wait for the process to complete.
+
+## Command Line Flashing
+
+1. Place your keyboard into reset. 
+2. Flash the board by typing `bootloadHID -r` followed by the path to your `.hex` file.
+
+### Windows Manual Installation
+For MSYS2:
+1. Download the BootloadHID firmware package from https://www.obdev.at/downloads/vusb/bootloadHID.2012-12-08.tar.gz.
+2. Extract contents using a compatible tool, for example 7-Zip.
+3. Add to the MSYS path by copying `commandline/bootloadHID.exe` from the extracted archive to your MSYS2 installation, typically `C:\msys64\usr\bin`.
+
+For native Windows flashing, the `bootloadHID.exe` can be used outside of the MSYS2 environment.
+
+### Linux Manual Installation

+# Python Development in QMK
+
+This document gives an overview of how QMK has structured its python code. You should read this before working on any of the python code.
+
+## Script directories
+
+There are two places scripts live in QMK: `qmk_firmware/bin` and `qmk_firmware/util`. You should use `bin` for any python scripts that utilize the `qmk` wrapper. Scripts that are standalone and not run very often live in `util`.
+
+We discourage putting anything into `bin` that does not utilize the `qmk` wrapper. If you think you have a good reason for doing so please talk to us about your use case.
+
+## Python Modules
+
+Most of the QMK python modules can be found in `qmk_firmware/lib/python`. This is the path that we append to `sys.path`.
+
+We have a module hierarchy under that path:
+
+* `qmk_firmware/lib/python`
+    * `milc.py` - The CLI library we use. Will be pulled out into its own module in the future.
+    * `qmk` - Code associated with QMK
+        * `cli` - Modules that will be imported for CLI commands.
+        * `errors.py` - Errors that can be raised within QMK apps
+        * `keymap.py` - Functions for working with keymaps
+
+## CLI Scripts
+
+We have a CLI wrapper that you should utilize for any user facing scripts. We think it's pretty easy to use and it gives you a lot of nice things for free.
+
+To use the wrapper simply place a module into `qmk_firmware/lib/python/qmk/cli`, and create a symlink to `bin/qmk` named after your module. Dashes in command names will be converted into dots so you can use hierarchy to manage commands.
+
+When `qmk` is run it checks to see how it was invoked. If it was invoked as `qmk` the module name is take from `sys.argv[1]`. If it was invoked as `qmk-<module-name>` then everything after the first dash is taken as the module name. Dashes and underscores are converted to dots, and then `qmk.cli` is prepended before the module is imported.
+
+The module uses `@cli.entrypoint()` and `@cli.argument()` decorators to define an entrypoint, which is where execution starts.
+
+## Example CLI Script
+
+We have provided a QMK Hello World script you can use as an example. To run it simply run `qmk hello` or `qmk-hello`. The source code is listed below.
+
+```
+from milc import cli
+
+@cli.argument('-n', '--name', default='World', help='Name to greet.')
+@cli.entrypoint('QMK Python Hello World.')
+def main(cli):
+    cli.echo('Hello, %s!', cli.config.general.name)
+```

+Quantum keycodes allow for easier customization of your keymap than the basic ones provide, without having to define custom actions.
 
 All keycodes within quantum are numbers between `0x0000` and `0xFFFF`. Within your `keymap.c` it may look like you have functions and other special cases, but ultimately the C preprocessor will translate those into a single 4 byte integer. QMK has reserved `0x0000` through `0x00FF` for standard keycodes. These are keycodes such as `KC_A`, `KC_1`, and `KC_LCTL`, which are basic keys defined in the USB HID specification.

+3. 使用 `git clone https://github.com/此处添GitHub用户名/此处添仓库名.git`这个命令把仓库同步到你的电脑中。
+4. 您要是想开发一个新特性的话可以先创建一个issue和Q酱的维护者讨论一下您要做什么。
+5. 使用`git checkout -b 此处写分支名字（别用汉字）`命令来创建一个分支（branch）用于开发。
+6. 对要解决的问题或要添加的特性进行适当的更改。
+7. 使用 `git add 把改变的文件的目录写这里` 可以添加改变的文件内容到git用于管理工程状态的索引（快照）里。
+8. 使用 `git commit -m "这里写修改的相关信息"` 来描述你做出了什么修改。
+9. 使用 `git push origin 此处写分支名字`来把你的更改同步到GitHub库里（反正不是打篮球那个库里）。
+10. 提交一个[QMK 固件的pull request](https://github.com/qmk/qmk_firmware/pull/new/master)。
+11. 给你的pull request拟一个标题，包括简短的描述和问题或错误代码。比如, 你可以起一个这样的"Added more log outputting to resolve #4352"（最好用英语，毕竟Q酱的中文也不是那么的溜，有可能会看不懂中文）。
+12. 在描述（description）里面写你做了哪些更改，你的代码里还存在什么问题, 或者你想问维护的小可爱们的问题。你的your pull request有点小问题无伤大雅(本来也没有完美的代码嘛), 维护的小可爱们会竭尽全力帮您改进的！
+13. 维护人员审查代码可能需要一些时间。
+14. 维护人员会通知您要更改什么地方，然后您就按照建议改一改。
+15. 预祝您合并成功！
+
+# 代码规范
+
+其实也没有什么特别严格的规范啦，但是俗话说的好：没有规矩，不成方圆。您可以看一下您的要改动的代码周围的画风，然后保持队形。如果你感觉周围都不知道是什么牛鬼蛇神的话就看看下面的建议：
+
+* 我们用肆(4)个空格来缩进(软件中也可以设置到Tab键)
+* 我们使用改良的1TBS(允许单行样式)
+  * 左大括号: 在开放性语句块那行的末尾
+  * 右大括号: 和开放性语句块第一个字母对齐
+  * Else If: 将右大括号放在行的开头，下一个左大括号放在同一行的结尾
+  * 可选大括号: 可选大括号是必选的
+    * 应该这样: if (condition) { return false; }
+    * 不应该这样: if (condition) return false;
+* 建议使用C语言风格的注释: `/* */`
+  * 把注释想象成一个描述特征的故事
+  * 充分使用注释来描述你为何这样修改
+  * 有些公认的东西就不要写到注释里面了
+  * 如果你不知道注释是否多余,看下面
+* 一般不要主动换行，主动换行的话每行不要超过76列
+* 要把 `#pragma once` 放到头文件的开始哦，抛弃老土的(`#ifndef THIS_FILE_H`, `#define THIS_FILE_H`, ..., `#endif`)吧
+* 下面两种预处理命令都可以用: `#ifdef DEFINED` 还有 `#if defined(DEFINED)`
+  * 以上那句对处女座不是很友好哈，处女座的朋友们就别纠结了，直接 `#if defined(DEFINED)` 。
+  * 还有就是选好一种风格就一直用，一直用一直爽，不要朝三暮四, 除非你要变化到多重条件的 `#if`。
+  * `#` 和 `if`要挨在一起哦，再让本空格在中间冒充电灯泡本空格会生气的。
+  * 以下是缩进规则:
+    * 首先考虑可读性，强迫症的朋友们总想要保持代码的高一致性，这样可不好。
+    * 保证文件已有风格不变。如果代码本来就是杂糅风格，那就见机行事，让你的修改更有意义些。
+    * 其实你也可以在缩进的时候看看周围其他代码，然后范水模山，预处理命令可以有自己的缩进风格。
+
+可以参照下面:
+
+```c
+/* foo 的 Enums*/
+enum foo_state {
+  FOO_BAR,
+  FOO_BAZ,
+};
+
+/* 有返回值的情况 */
+int foo(void) {
+  if (some_condition) {
+    return FOO_BAR;
+  } else {
+    return -1;
+  }
+}
+```
+
+# Clang-format的自动格式化
+[Clang-format](https://clang.llvm.org/docs/ClangFormat.html) 是LLVM的一部分，可以帮你自动格式化代码。我们给你准备好了一个适用于以上规范的配置文件，会帮你调整缩进和换行，你只需要写好括号就好。有了它，你再也不用担心调整代码格式太耗时，没有时间陪伴自己（虚构）的另一半了。
+
+使用[LLVM 完整安装](http://llvm.org/builds/)可以在Windows上安装clang-format, Ubuntu用户要用`sudo apt install clang-format`。
+
+命令行的朋友们, 加上 `-style=file`选项就会自动在QMK的根目录寻找.clang-format配置文件了。
+
+VSCode用户, 标准的 C/C++ 插件就支持clang-format, 或者可以用[独立扩展](https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.ClangFormat)也行。
+
+有些东西(比如LAYOUT宏) 会被clang-format打乱，所以那些文件就别用clang-format了,这里就教您一个小窍门，在`// clang-format off` 和 `//clang-format on`之间装上会被搞乱的代码就好了。
+
+# 一般教程
+
+你可以给Q酱的不同部分添砖加瓦，但也要用不同的方法严谨检查。不论你修改哪里最好还是看看下边。
+
+* 将PR（pull request）分成一个个的逻辑单元。 比如，不要一次将两个新特性PR出去。要添加的特性排好队，一个一个来。
+* 提交之前看一眼，`git diff --check`的空格一定要写对了
+* 确定你的代码能通过编译
+  * 布局: 确定`make keyboard:your_new_keymap` 不返回错误
+  * 键盘: 确定 `make keyboard:all` 不返回错误
+  * 核心代码: 确定 `make all` 不返回错误
+* 提交的信息尽量明确。第一行写点简短介绍(每行不多于70个英文字母), 第二行空着,第三行和后面就要写些必要的细节了。最好用英文写，比如:
+
+```
+Adjust the fronzlebop for the kerpleplork
+
+The kerpleplork was intermittently failing with error code 23. The root cause was the fronzlebop setting, which causes the kerpleplork to activate every N iterations.
+
+Limited experimentation on the devices I have available shows that 7 is high enough to avoid confusing the kerpleplork, but I'd like to get some feedback from people with ARM devices to be sure.
+```
+
+## 文档
+
+想帮助Q酱当然是先看文档最简单了。找到这个文档哪里错了然后改正它对于你来说超级简单! 我们也对有写文档能力的人求贤若渴，如果你是对的人[点这个](#Q酱，我在哪能帮助你嘞?)!
+
+文档呢，都静静的放在`qmk_firmware/docs` 目录里, 也或者您想为网页做贡献的话也是可以的哦。
+
+在文档中附代码案例时, 先观察文档其他地方的命名规范。比如, 把enums的名字都改成像`my_layers`或者`my_keycodes`来防止名字不一致的enums被当作特务枪毙:
+
+```c
+enum my_layers {
+  _FIRST_LAYER,
+  _SECOND_LAYER
+};
+
+enum my_keycodes {
+  FIRST_LAYER = SAFE_RANGE,
+  SECOND_LAYER
+};
+```
+
+## 布局
+
+大多数QMK新手都从创建一个自己的布局开始。我们尽力保证布局规范宽松 (毕竟布局是个性的体现) 不过建议遵守以下准则，这样可以让别人更好理解你的代码
+
+* 用 [模板](documentation_templates.md)写个`readme.md`。
+* 所有的布局PR都会被squash, 如果你想知道你的提交是怎么被squash的那你就自己来吧
+* 不要把新特性和布局一起PR。可以分别PR他们
+* 布局文件夹就不要放`Makefile`了，这个操作都过时啦
+* 更新文件头部的copyrights(看`%YOUR_NAME%`那)
+
+## 键盘
+
+QMK的最终归宿是键盘。有些键盘是社区维护的，有一些是制作这些键盘的人维护的。`readme.md`会告诉你是谁维护了这个键盘，如果你对某个键盘有疑问，可以 [创建一个Issue](https://github.com/qmk/qmk_firmware/issues) 来问一问维护者。
+
+我们建议你按下面的来操作:
+
+* 用[模板](documentation_templates.md)写`readme.md`。
+* 提交数量尽量合理，不然我们可就要把你的PR给squash了。
+* 不要把新特性和新键盘一起PR。可以分别PR他们
+* 用父文件夹的名字命名 `.c`/`.h`文件, 比如`/keyboards/<kb1>/<kb2>/<kb2>.[ch]`
+* 键盘文件夹就不要放`Makefile`了，这个操作都过时啦
+* 更新文件头部的copyrights(看`%YOUR_NAME%`那)
+
+## Quantum/TMK 核心
+
+在您废寝忘食地开发Q酱新特性或者帮Q酱驱虫之前，一定要确保你的工作是有意义的。看看[了解QMK](understanding_qmk.md)你会对Q酱有更深的了解，这个文档将带你领略QMK的程序流程。现在你应该和维护团对谈谈来了解实现你想法的最佳方法了。一下渠道都可以：
+
+* [在Discord交流](https://discord.gg/Uq7gcHh)
+* [建立一个Issue](https://github.com/qmk/qmk_firmware/issues/new)
+
+新特性和BUG的修复影响所有键盘。开发组也在翻修QMK。所以，在实施重大返修之前一定要讨论一下。如果你在没有事先与维护团队沟通的情况下提交了一个PR，而且你的选择与维护团队的计划方向不符，那你可能要面临大改了。
+
+修复BUG或者开发新特性之前看看这个：
+
+* **默认不启用** - QMK运行的芯片多数内存有限，所以首要考虑的还应该是布局不要被破坏，于是特性默认是不启用的。你喜欢什么特性的话就打开它，如果你觉得有些特性应该默认开启或者你能帮助缩减代码，那就联系维护组吧。
+* **提交之前在本地编译** - 这个简直就是家喻户晓了，但是也确实需要编译啊！ 我们的Travis系统会发现一切问题，但是自己编译一下可要比在线等快多了。
+* **注意版本和芯片平台** - 有那么几个键盘有支持不同配置甚至是不同芯片的版本。试着写一个能AVR和ARM两个平台运行的特性，或者在不支持的平台自动禁用。
+* **解释你的新特性** - 在`docs/`写个文档, 你可以创建新文档或者写到现有文档中。如果你不把它记录下来，其他人就无法从你的努力中获益。
+
+也可以看看以下建议：
+
+* 提交数量尽量合理，不然我们可就要把你的PR给squash了。
+* 不要把新特性、布局和键盘一起PR。可以分别PR他们。
+* 给你的特性写[单元测试](unit_testing.md)。
+* 你编辑的文件风格要一致，如果风格不明确或者是混搭风的，你就要先看看[代码规范](#代码规范)确认情况。
+
+## 重构
+
+为了保持QMK脉络清晰，Q酱打算深入规划重构一下自己，然后让合作者进行修改。如果你有重构的思路或建议[创建一个issue](https://github.com/qmk/qmk_firmware/issues), Q酱很乐意讨论一下怎么改进一下。
+
+# 行为守则对于我来说有何意义?
+
+我们的[行为守则](https://github.com/qmk/qmk_firmware/blob/master/CODE_OF_CONDUCT.md) 是说明您有责任尊重和礼貌地对待项目中的每个人，无论他们的身份如何。 如果你是我们行为准则所描述的不当行为的受害者，我们将站在你这边，并按照行为准则对施暴者进行适当谴责。

+# 关于构建的常见问题
+
+本页所写是QMK构建的常见问题.如果你还没有进行过编译,就看一下[构建环境搭建](getting_started_build_tools.md) 和 [make的说明](getting_started_make_guide.md).
+
+## 如果您不能在Linux上编程
+您需要适当的权限才能操作设备。对于Linux用户, 请参阅下方有关`udev`规则的说明。如果您对`udev`有问题，解决方法是用`sudo`命令。如果您不熟悉此命令，使用`man sudo`查看其手册或[看这个网页](https://linux.die.net/man/8/sudo).
+
+在你的主控是ATMega32u4时，以下是使用`sudo`命令的样例：
+
+    $ sudo dfu-programmer atmega32u4 erase --force
+    $ sudo dfu-programmer atmega32u4 flash your.hex
+    $ sudo dfu-programmer atmega32u4 reset
+
+或只用；
+
+    $ sudo make <keyboard>:<keymap>:dfu
+
+使用`sudo`运行`make`一般来说**不**推荐，如果可能，尽量使用前一种方法之一。
+
+### Linux `udev` 规则
+在Linux上，您需要适当的权限才能访问MCU。你也可以在刷新固件时使用 `sudo`，或把这些文件放到`/etc/udev/rules.d/`。
+
+**/etc/udev/rules.d/50-atmel-dfu.rules:**
+```
+# Atmel ATMega32U4
+SUBSYSTEMS=="usb", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ff4", MODE:="0666"
+# Atmel USBKEY AT90USB1287
+SUBSYSTEMS=="usb", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ffb", MODE:="0666"
+# Atmel ATMega32U2
+SUBSYSTEMS=="usb", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ff0", MODE:="0666"
+```
+
+**/etc/udev/rules.d/52-tmk-keyboard.rules:**
+```
+# tmk键盘产品     https://github.com/tmk/tmk_keyboard
+SUBSYSTEMS=="usb", ATTRS{idVendor}=="feed", MODE:="0666"
+```
+**/etc/udev/rules.d/54-input-club-keyboard.rules:**
+
+```
+# Input Club keyboard bootloader
+SUBSYSTEMS=="usb", ATTRS{idVendor}=="1c11", MODE:="0666"
+```
+
+### 串行设备在Linux上检测不到bootloader模式
+确保您的内核对您的设备有相应的支持。 如果你的设备是 USB ACM, 比如Pro Micro (Atmega32u4)，就要加上`CONFIG_USB_ACM=y`. 其他设备可能需要`USB_SERIAL` 及其任何子选项。
+
+## DFU Bootloader的未知设备
+
+如果您在使用Windows来刷新键盘的时候碰到了问题，检查设备管理器。如果在键盘处于 "bootloader模式"时你看到 "未知设备"，说明你可能面临设备问题。
+
+重新运行MSYS2上的安装脚本或许会凑效（比如在MSYS2/WSL运行 `./util/qmk_install.sh`) 或者重新安装QMK工具箱也可能会解决你的问题。
+
+如果以上方法还是短针攻疽，那您可能需要使用[Zadig Utility](https://zadig.akeo.ie/)。下载此程序, 找到设备问题, 然后选择 `WinUSB`选项, 然后点击"Reinstall driver"。完成后再试试刷新你的键盘。倘若依然徒劳无功，那就尝试所有选项直到好用为止。
+
+?> 事实上没有一个驱动的最佳选择，有些选项就是和某些系统相辅相成。但libUSB和WinUSB似乎也算是这里的最佳选择了。
+如果bootloader在设备列表中没有显示，你可能要使能 "List all devices"选项在选项菜单中`Options`，然后找到有问题的bootloader设备。(译者注：在win10中可能为 查看-显示隐藏的设备)
+
+
+## WINAVR已淘汰
+不再推荐使用WINAVR，使用可能会导致问题
+详情请见[TMK Issue #99](https://github.com/tmk/tmk_keyboard/issues/99).
+
+## USB VID 和 PID
+你可以在编辑`config.h`时使用任何你想用的ID值。实际上，使用任何可能未使用的ID都没有问题，除了有极低的与其他产品发生冲突的可能性。
+
+大多数QMK主板使用`0xFEED`作为vendor ID。您应该查看其他键盘，以确保选择了唯一的Product ID。
+
+也要看看这个。
+https://github.com/tmk/tmk_keyboard/issues/150
+
+一也可以在下方链接购买一个唯一的VID:PID。不过个人使用似乎用不着这个。

+
+### avr-gcc 8.1 和 LUFA
+
+如果你把avr-gcc升级到7以上你可能会遇到关于LUFA的问题。比如:
+
+`lib/lufa/LUFA/Drivers/USB/Class/Device/AudioClassDevice.h:380:5: error: 'const' attribute on function returning 'void'`
+
+那你就需要在brew中把avr-gcc回退到7。
+
+```
+brew uninstall --force avr-gcc
+brew install avr-gcc@8
+brew link --force avr-gcc@8
+```
+
+### 我刷新了我的键盘但是键盘不工作/按键没有注册 - 而且还是ARM的 (rev6 planck, clueboard 60, hs60v2, etc...) (Feb 2019)
+由于EEPROM在基于ARM的芯片上的工作原理，保存的设置可能不再有效。这会影响默认层，而且*或许*在某些情况下，会使键盘不好用，我们仍在调查这些情况。重置EEPROM将解决此问题。
+
+[Planck rev6键盘重置EEPROM](https://cdn.discordapp.com/attachments/473506116718952450/539284620861243409/planck_rev6_default.bin) 是用于强制重置EEPROM的。刷入这个文件后，再次刷入正常固件，这会将键盘恢复到_正常_工作状态。
+[Preonic rev3键盘重置EEPROM](https://cdn.discordapp.com/attachments/473506116718952450/537849497313738762/preonic_rev3_default.bin)
+
+如果以任何形式启用了bootmagic， 那么您还需要(看[Bootmagic文档](feature_bootmagic.md) 以及键盘信息，以了解如何执行此操作的详细信息).

+# 调试的常见问题
+
+本篇详细介绍了人们在键盘故障排除时的各种常见问题。
+
+# 调试控制台
+
+## `hid_listen` 无法识别设备
+当设备的调试控制台未就绪时，您将看到如下内容：
+
+```
+Waiting for device:.........
+```
+
+插入设备后，*hid_listen*找到该设备，您将收到以下消息：
+
+```
+Waiting for new device:.........................
+Listening:
+```
+
+如果您无法获得这条“Listening:”消息，请尝试在[Makefile]中使用 `CONSOLE_ENABLE=yes`
+
+在Linux这样的操作系统上，你可能需要一些权限。
+- 使用`sudo hid_listen`
+
+## 控制台没有返回消息
+检查:
+- *hid_listen* 找到了你的设备。看前面。
+- 输入**Magic**+d打开调试。详见[Magic Commands](https://github.com/tmk/tmk_keyboard#magic-commands)。
+- 设置`debug_enable=true` ，一般存在于**matrix.c**的`matrix_init()`中。
+- 尝试使用'print'函数而不要用调试输出。详见**common/print.h**。
+- 断开其他有控制台功能的设备。 详见[Issue #97](https://github.com/tmk/tmk_keyboard/issues/97)。
+
+## Linux或UNIX这样的系统如何请求超级用户权限
+用'sudo'来执行*hid_listen*就有权限了。
+```
+$ sudo hid_listen
+```
+
+或者把一个文件放到规则文件夹来为TMK设备添加*udev规则*，不同系统的目录可能有所不同。
+
+文件: /etc/udev/rules.d/52-tmk-keyboard.rules(在Ubuntu系统的情况下)
+```
+# tmk keyboard products     https://github.com/tmk/tmk_keyboard
+SUBSYSTEMS=="usb", ATTRS{idVendor}=="feed", MODE:="0666"
+```
+
+***
+
+# 其他
+## 安全注意事项
+
+你应该不想要把你的键盘变成"砖头"吧，就是变成没法重写固件的那种。
+下面讲解一些参数来告诉你什么风险很大（其实也不是很大）。
+
+- 假如你键盘表面没有设计重置键"RESET", 那你要进入bootloader的话就要按PCB上的RESET了。
+  按PCB上的RESET要拧开键盘底部。
+- 如果 tmk_core / common 里面的文件丢失键盘可能失灵。
+- .hex太大可能不太好; `make dfu` 会删除块，检验大小（咦?好像反了...）。
+  一但出错，刷新键盘失败的话就困在DFU出不去了。
+  - 所以, 要知道大小限制。 Planck键盘上.hex文件最大大小是 is 7000h (十进制是28672)
+
+```
+Linking: .build/planck_rev4_cbbrowne.elf                                                            [OK]
+Creating load file for Flash: .build/planck_rev4_cbbrowne.hex                                       [OK]
+
+Size after:
+   text    data     bss     dec     hex filename
+      0   22396       0   22396    577c planck_rev4_cbbrowne.hex
+```
+
+  - 上面那个文件大小是 22396/577ch，比28672/7000h小
+  - 当你有一个合适的.hex文件时，你就要重试加载那个了
+  - 您在键盘Makefile中的某些选项可能消耗额外内存；注意以下这几个
+    BOOTMAGIC_ENABLE, MOUSEKEY_ENABLE, EXTRAKEY_ENABLE, CONSOLE_ENABLE, API_SYSEX_ENABLE
+- DFU 工具/不/可以写入bootloader (unless you throw in extra fruit salad of options), 
+  所以还是有点危险的
+- EEPROM大概有100000次循环寿命。不要总是频繁重写固件；EEPROM会玩坏的。
+## 全键无冲不好用
+首先你要在**Makefile**用如下命令编译固件`NKRO_ENABLE`。
+
+全键无冲还不好用的话试着用`Magic` **N** 命令(默认是`LShift+RShift+N`)。这个命令会在**全键无冲**和**六键无冲**之间临时切换。有些情况**全键无冲**不好用你就需要使用**六键无冲**模式，尤其是在BIOS中。
+
+如果你的固件使用`BOOTMAGIC_ENABLE`编译的你要用`BootMagic` **N** 命令(默认`Space+N`)打开开关。这个设置保存在EEPROM中并保存在电源循环中。
+<!--翻译问题：上面这句翻译的不贴切 -->
+
+https://github.com/tmk/tmk_keyboard#boot-magic-configuration---virtual-dip-switch
+
+
+## 指点杆需要复位电路(PS/2 鼠标支持)
+如果没有复位电路，由于硬件初始化不正确，您将得到不一致的结果。查看TPM754复位电路。
+

+
+
+## 矩阵不可读16以上的列
+当列超过16时[matrix.h]的`read_cols()`中，用`1UL<<16`而不要用`1<<16`。
+
+在C语言中`1` 是一个[int] 类型的[16 bit]值，在AVR中你不能左移大于15次。如果你使用`1<<16`的话会得到意外的零。你要用 [unsigned long]类型，比如`1UL`。
+
+http://deskthority.net/workshop-f7/rebuilding-and-redesigning-a-classic-thinkpad-keyboard-t6181-60.html#p146279
+
+
+## Bootloader跳转不好用
+在**Makefile**中正确配置**Makefile**大小。如果分区大小不正确，引导加载程序可能无法从**Magic command**和**Boot Magic**加载。
+```
+#   bootloader字节数：
+#   Atmel DFU loader(ATmega32U4)   4096
+#   Atmel DFU loader(AT90USB128)   8192
+#   LUFA bootloader(ATmega32U4)    4096
+#   Arduino Caterina(ATmega32U4)   4096
+#   USBaspLoader(ATmega***)        2048
+#   Teensy   halfKay(ATmega32U4)   512
+#   Teensy++ halfKay(AT90USB128)   2048
+OPT_DEFS += -DBOOTLOADER_SIZE=4096
+```
+AVR引导大小是通过**BOOTSZ**熔丝位来设置的。查阅你单片机的datasheet。
+记住，datasheet用的是**Word**(2字节)表示大小和地址，TMK用的是**Byte**。
+
+AVR引导部分位于闪存的末尾，如下所示（Application是应用区，Bootloader是引导区）。
+```

+
+详情请见下方issue。

+
+如果你使用TeensyUSB, 有一个[已知bug](https://github.com/qmk/qmk_firmware/issues/164)硬件重置按钮阻止软件定义重置键工作。重新插拔键盘就好了。
+
+## 特殊额外键不起作用(系统，音频控制键)
+你要在`rules.mk`定义`EXTRAKEY_ENABLE`在QMK中使用它们。
+
+```
+EXTRAKEY_ENABLE = yes          # 音频控制和系统控制
+```
+
+## 睡眠唤醒不好用
+
+在Windows查看设备管理器中该键盘设备属性中电源管理选项卡中的`允许此设备唤醒计算机(O)`是否勾选。同时看一眼BIOS设置。
+
+在主机睡眠时按下任何键都可以唤醒了。
+
+## 使用Arduino?
+
+**注意Arduino的针脚名字和主控芯片的不一样。** 比如, Arduino的`D0`并不是`PD0`。自己用原理图捋一下电路。
+
+- http://arduino.cc/en/uploads/Main/arduino-leonardo-schematic_3b.pdf
+- http://arduino.cc/en/uploads/Main/arduino-micro-schematic.pdf
+
+Arduino Leonardo和micro使用**ATMega32U4**，该芯片TMK可用，但Arduino的bootloader会导致问题。
+
+## 为锁定键添加指示灯
+你要自制CapsLock, ScrollLock 和 NumLock指示灯？见下文。
+
+http://deskthority.net/workshop-f7/tmk-keyboard-firmware-collection-t4478-120.html#p191560

+# 布局常见问题
+
+本页本页包含人们经常遇到的关于布局的问题。如果你觉得没什么问题，请先看[布局概览](keymap.md)。
+
+## 我能用什么键码?
+看[键码](keycodes.md)你可以找到你能用的键码索引。可以的话这些链接可以连接到更广泛的文档。
+
+键码实际上定义在[common/keycode.h](https://github.com/qmk/qmk_firmware/blob/master/tmk_core/common/keycode.h).
+
+## 默认的键码什么样?
+
+世界上有三种标准键盘设计，分别是：ANSI, ISO, and JIS. 主要是北美用ANSI(译者注：中国很多键盘使用这个), 欧洲和非洲主要使用ISO，日本使用JIS。未提及的区域通常使用ANSI或ISO。与这些设计对应的键代码如下所示：
+
+<!-- 该图片的来源: http://www.keyboard-layout-editor.com/#/gists/bf431647d1001cff5eff20ae55621e9a -->
+![键盘设计图](https://i.imgur.com/5wsh5wM.png)
+
+## 我有一些键变成了其他功能或者不工作了
+
+QMK有两个功能，Bootmagic和命令行，它允许您在运行中更改键盘的行为。该功能包括但不仅限于, 交换Ctrl/Caps，关闭界面，交换Alt/Gui，交换 Backspace/Backslash，禁用所有键，以及其他的行为改变。
+
+快速解决方法是插入键盘时按住`Space`+`Backspace`。该操作将重置已保存设置，让这些键回复初始功能。这招不好用的话参阅下方：
+
+* [Bootmagic](feature_bootmagic.md)
+* [命令](feature_command.md) 
+
+## 菜单键不好用
+
+现在大多数键盘 `KC_RGUI`和`KC_RCTL`中间的键子叫做`KC_APP`。这是因为在这个键子发明之前相关标准里就已经有键叫做`MENU(菜单)`了，所以微软叫他`APP(应用)`键。
+
+## `KC_SYSREQ` 不工作
+使用抓屏的键码(`KC_PSCREEN`或`KC_PSCR`)而不用`KC_SYSREQ`。组合键'Alt + Print Screen'会被当作'System request'。
+
+见[issue #168](https://github.com/tmk/tmk_keyboard/issues/168)和
+* http://en.wikipedia.org/wiki/Magic_SysRq_key
+* http://en.wikipedia.org/wiki/System_request
+
+## 电源键不工作
+
+这有点让人困惑,QMK有两个"Power(电源)"键码: `KC_POWER` 在键盘/小键盘的HID使用页面中，`KC_SYSTEM_POWER` (或者叫`KC_PWR`)在用户页。
+
+前者只能被macOS识别，但是后者，即`KC_SLEP`和`KC_WAKE`三大主要操作系统全都支持，所以推荐使用这两个。Windows下这些键立即生效，macOS要长按直到弹出对话框。
+
+## 自动大小写锁定
+可以解决'the'问题(正常应为The)。我经常在输入'The'时不慎输入了'the'或者'THe'。自动大小写锁定可以修正此类问题。详见下方链接。
+https://github.com/tmk/tmk_keyboard/issues/67
+
+## 修改 键/层 卡住
+除非正确配置层切换，否则修改键或层可能会卡住。
+对于修改键和图层操作，必须把`KC_TRANS`放到目标层的相同位置，用于注销修改键或在释放事件时返回到上一层。
+* https://github.com/tmk/tmk_core/blob/master/doc/keymap.md#31-momentary-switching
+* http://geekhack.org/index.php?topic=57008.msg1492604#msg1492604
+* https://github.com/tmk/tmk_keyboard/issues/248
+
+
+## 机械自锁开关支持Mechanical Lock Switch Support
+
+本功能用于*机械自锁开关*比如[this Alps one](http://deskthority.net/wiki/Alps_SKCL_Lock)。你可以通过向`config.h`添加以下宏来使能该功能：
+
+```
+#define LOCKING_SUPPORT_ENABLE
+#define LOCKING_RESYNC_ENABLE
+```
+
+在使能该功能后，要在键盘中使用`KC_LCAP`, `KC_LNUM` 和 `KC_LSCR`这三个键码。
+
+远古机械键盘偶尔会有自锁机械开关，现在几乎没有了。***大多数情况下你不需要使用该功能，且要使用`KC_CAPS`, `KC_NLCK`和`KC_SLCK`这三个键码。***
+
+## 输入ASCII之外的特殊字符比如Cédille 'Ç'
+没有在所有系统中输入这个的通用方法。你要定义针对你的特定操作系统或布局的**宏**。
+
+比如看这个**宏**代码的文章。
+
+http://deskthority.net/workshop-f7/tmk-keyboard-firmware-collection-t4478-120.html#p195620
+<!--翻译问题：下方维基百科链接应全部替换为中文链接，暂未找到全部-->
+在**Windows**上，可以用`AltGr`键或**Alt码**。
+* http://en.wikipedia.org/wiki/AltGr_key
+* https://zh.wikipedia.org/wiki/Alt%E7%A0%81
+
+在**Mac OS**定义`Option`键组合。
+* https://zh.wikipedia.org/wiki/Option%E9%94%AE#%E6%9B%BF%E4%BB%A3%E9%94%AE%E7%9B%98%E8%BE%93%E5%85%A5
+
+在**Xorg**可以改用`compose`键。
+* http://en.wikipedia.org/wiki/Compose_key
+
+下方链接查看**Unicode**输入。
+* http://en.wikipedia.org/wiki/Unicode_input
+
+## macOS上的`Fn` 
+
+不像大多数FN键，苹果上那个有自己的键码...呃，基本上算吧。 他取缔了基本6键无冲HID报告的第六个键码 -- 所以苹果键盘其实是5键无冲的。
+
+技术上说QMK可以发送这个键。但是，这样做需要修改报告格式以添加FN键的状态。这还不是最糟糕的，你的键盘的VID和PID和真的苹果键盘不一样的话还不会被识别。
+QMK官方支持这个会被律师函的，所以就当我没说过。
+
+详见[issue#2179](https://github.com/qmk/qmk_firmware/issues/2179)。
+
+
+## Mac OSX的媒体控制键
+#### KC_MNXT 和 KC_MPRV 在Mac上不好用
+使用 `KC_MFFD`(`KC_MEDIA_FAST_FORWARD`) 和 `KC_MRWD`(`KC_MEDIA_REWIND`)，不要用 `KC_MNXT` 和 `KC_MPRV`.
+详见 https://github.com/tmk/tmk_keyboard/issues/195
+
+
+## Mac OSX中支持那些键?
+你可以从此源码中获知在OSX中支持哪些键码
+
+`usb_2_adb_keymap` 阵列映射 键盘/小键盘 页用于ADB扫描码(OSX内部键码).
+
+https://opensource.apple.com/source/IOHIDFamily/IOHIDFamily-606.1.7/IOHIDFamily/Cosmo_USB2ADB.c
+
+`IOHIDConsumer::dispatchConsumerEvent`会处理用户页面用法。
+<!--翻译问题：上面那两句翻译的不好-> handles Consumer page usages. -->
+https://opensource.apple.com/source/IOHIDFamily/IOHIDFamily-606.1.7/IOHIDFamily/IOHIDConsumer.cpp
+
+
+## Mac OSX中的JIS键
+岛国特别键比如`無変換(Muhenkan)`, `変換(Henkan)`, `ひらがな(hiragana)`OSX是不是别的。You can use **Seil** to enable those keys, try following options.
+<!--翻译问题：以上“岛国特别键”没有任何地域歧视的意思 -->
+* 在电脑键盘上使能NFER键
+* 在电脑键盘上使能XFER键
+* 在电脑键盘上使能KATAKAN键
+
+https://pqrs.org/osx/karabiner/seil.html
+
+
+## RN-42蓝牙模块与Karabiner不能有效协同工作
+Karabiner - Mac OSX的改键软件 - 默认RN-42模块是不会被响应的。想要Karabiner和你的键盘协同工作你要使能此选项：
+https://github.com/tekezo/Karabiner/issues/403#issuecomment-102559237
+
+此问题详见下方链接。
+https://github.com/tmk/tmk_keyboard/issues/213
+https://github.com/tekezo/Karabiner/issues/403
+
+
+## Esc 和 <code>&#96;</code> 双功能键
+
+请见[Grave Escape](feature_grave_esc.md)功能。
+
+## 右侧双角色修改键(诸如Shift、Alt等有修改其他键作用的键)变箭头键
+右侧修改键单击时会变为箭头键，长按就还是修改键。在TMK中双角色键称之为**TAP**.

+
+双角色键说明: https://en.wikipedia.org/wiki/Modifier_key#Dual-role_keys
+
+
+## Mac OSX的弹出键
+`KC_EJCT` 键码在OSX可以使用 https://github.com/tmk/tmk_keyboard/issues/250
+似乎Windows10会忽略该键码，Linux/Xorg可以识别该键码但默认不映射。
+
+目前尚不清楚如何在真正的苹果键盘按出弹出键。HHKB使用`F20`用于弹出键(`Fn+f`)，该功能在MAC模式有效但不保证与苹果弹出键码相符。
+
+
+## `action_util.c`中的 `weak_mods`和`real_mods`是什么
+___待改善___
+
+real_mods 用于保存实际(物理)修改键的实际状态。
+weak_mods 用于保存虚拟或临时修改键，它将不会影响实际修改键。
+
+以按下左侧Shift键然后输入ACTION_MODS_KEY(LSHIFT, KC_A)为例，
+
+在weak_mods时，
+* (1) 按下不抬起左Shift: real_mods |= MOD_BIT(LSHIFT)
+* (2) 按 ACTION_MODS_KEY(LSHIFT, KC_A): weak_mods |= MOD_BIT(LSHIFT)
+* (3) 抬起 ACTION_MODS_KEY(LSHIFT, KC_A): weak_mods &= ~MOD_BIT(LSHIFT)
+real_mods 还是保持在修改状态。
+
+在没有weak_mods时，
+* (1) 按下不抬起左Shift: real_mods |= MOD_BIT(LSHIFT)
+* (2) 按 ACTION_MODS_KEY(LSHIFT, KC_A): real_mods |= MOD_BIT(LSHIFT)
+* (3) 抬起 ACTION_MODS_KEY(LSHIFT, KC_A): real_mods &= ~MOD_BIT(LSHIFT)
+此时real_mods失去‘实际左Shift’的状态。
+
+weak_mods和real_mods现已全部加入键盘数据包发送豪华套餐。

+# 如何在QMK中使用Github
+
+Github can be a little tricky to those that aren't familiar with it - this guide will walk through each step of forking, cloning, and submitting a pull request with QMK.
+
+?> 本教程假设您已安装GitHub，并且您喜欢使用命令行工作。
+
+首先 [Github上的QMK页面](https://github.com/qmk/qmk_firmware), 您能看到右上方有个按钮写着"Fork":
+
+![从Github上分叉](http://i.imgur.com/8Toomz4.jpg)
+
+如果你是某组织成员，你将需要选择分叉到哪个账户。一般情况下, 你是想要分叉到你的私人账户下。当你完成分叉 (有时需要等一会), 点击"Clone or Download" 按钮:
+
+!从Github下载](http://i.imgur.com/N1NYcSz.jpg)
+
+你要选择 "HTTPS", 然后选择链接复制:
+
+![HTTPS链接](http://i.imgur.com/eGO0ohO.jpg)
+
+然后，在命令行输入`git clone `，然后粘贴你的链接:
+
+```
+user@computer:~$ git clone https://github.com/whoeveryouare/qmk_firmware.git
+Cloning into 'qmk_firmware'...
+remote: Counting objects: 46625, done.
+remote: Compressing objects: 100% (2/2), done.

+Resolving deltas: 100% (29362/29362), done.
+Checking out files: 100% (2799/2799), done.
+```
+
+现在你本地计算机有QMK的分叉了,你可以添加你的布局了, 为你的键盘编译并刷新固件吧。如果你觉得你的修改很不错, 你可以添加,提交,然后想你的分叉推出（pull）你的改变，像这样:
+
+```
+user@computer:~$ git add .
+user@computer:~$ git commit -m "adding my keymap"
+[master cccb1608] adding my keymap
+ 1 file changed, 1 insertion(+)
+ create mode 100644 keyboards/planck/keymaps/mine/keymap.c
+user@computer:~$ git push
+Counting objects: 1, done.
+Delta compression using up to 4 threads.
+Compressing objects: 100% (1/1), done.

+To https://github.com/whoeveryouare/qmk_firmware.git
+ + 20043e64...7da94ac5 master -> master
+```
+
+现在你的改动已经在你Github上的分支中了 - 如果你回到这 (`https://github.com/你的GitHub账户名/qmk_firmware`) ,你可以点击下方所示按钮创建 "New Pull Request":
+
+![新的 Pull Request](http://i.imgur.com/DxMHpJ8.jpg)
+
+现在你可以看到你所做的一切 - 如果看起来不错, 就可以点击 "Create Pull Request"定稿了:
+
+![创建Pull Request](http://i.imgur.com/Ojydlaj.jpg)
+
+提交后,我们会开跟你说你的改动,要求您进行更改, 并最终接受您的更改!感谢您为QMK做的贡献 :)

+键盘上照明的通称。背光通常是一组LED灯，通过键帽或者按轴发光，但也不总是这样。
+
+## Bluetooth(蓝牙)
+一种短距离点对点无线协议。许多多无线键盘使用此协议。
+
+## Bootloader(引导加载程序)
+一种写到你单片机的保护区的特殊的程序，该程序可以使单片机升级自己的固件，通常是通过USB来升级。
+
+## Bootmagic(热改键)
+允许各种键盘行为动态变化的功能，如交换或禁用常用键。
+
+## C
+一种适用于系统代码的低级编程语言。大多数qmk代码是用C编写的。
+
+## Colemak
+一种流行的键盘布局。
+
+## Compile(编译)
+把人可读的代码转换成你的单片机可以运行的机器代码的过程。
+
+## Dvorak
+一个由August Dvorak博士在20世纪30年代创建的布局。Dvorak简化键盘(Dvorak Simplified Keyboard)的缩写。
+
+## Dynamic Macro(动态宏)
+一种记录在键盘上的宏，当键盘拔出或计算机重新启动时，宏将丢失。
+
+* [动态宏文档](feature_dynamic_macros.md)
+
+## Eclipse
+是一种受C语言开发者追捧的集成开发环境(IDE)。
+
+* [Eclipse安装说明](eclipse.md)
+
+## Firmware(固件)
+用来控制单片机的软件。
+
+## FLIP
+爱特梅尔(Atmel)提供的AVR器件刷写软件。我们一般推荐 [QMK刷写工具](https://github.com/qmk/qmk_flasher)，但是对于一些高级用例，需要FLIP。
+
+## git
+命令行版本控制软件
+
+## GitHub
+负责大多数QMK项目的网站。它是Git、问题跟踪和其他帮助我们运行qmk的功能的集成平台。
+
+## ISP(在系统编程)
+在系统编程(In-system programming), 使用外部硬件和JTAG管脚对AVR芯片进行编程的一种方法。
+
+## hid_listen
+从键盘接收调试消息的接口。 您可以使用[QMK Flasher](https://github.com/qmk/qmk_flasher)或[PJRC's hid_listen](https://www.pjrc.com/teensy/hid_listen.html)查看这些消息
+
+## Keycode(键码)
+表示特定键的2字节数据。`0x00`-`0xFF`用于[基本键码](keycodes_basic.md)而`0x100`-`0xFFFF`用于[量子键码](quantum_keycodes.md).
+
+## Key Down
+一个键按下尚未抬起时触发的事件。
+
+## Key Up
+一个键抬起时触发的事件。
+
+## Keymap(键映射)
+映射到物理键盘布局的一组键码，在按键和按键释放时进行处理。有时翻译为布局，意为软件上表示的布局，即映射。
+
+## Layer(层)
+为了让一个键实现多个功能的抽象结构。最高活动层有限。
+
+## Leader Key(前导键、设置菜单键)
+本功能允许您点击前导键，然后按顺序按1-3个键子来激活按键或其他量子功能。
+
+* [前导键文档](feature_leader_key.md)
+
+## LED
+发光二极管，键盘上最常用的指示灯装置。
+
+## Make
+用于编译所有源文件的软件包。可以使用`make`命令和其他参数来编译你的固件。
+
+## Matrix(矩阵)
+一种由列和行组成的接线模式，使单片机能够用较少的引脚检测按键。矩阵通常包含二极管，以达到全键无冲。
+
+## Macro(宏)
+本功能可以在敲击单个键后发送多个按键事件(hid报告)。
+
+* [宏文档](feature_macros.md)
+
+## MCU(单片机、微控制单元)
+微控制单元，键盘的处理器。
+
+## Modifier(修改键、修饰键、功能键)
+按住该键将会改变其他键的功能，修饰键包括 Ctrl, Alt, 和 Shift。
+
+## Mousekeys(鼠标键)
+本功能在您敲击键盘时会控制鼠标光标。
+
+* [鼠标键文档](feature_mouse_keys.md)
+
+## N-Key Rollover (NKRO、全键无冲)
+一种术语，适用于能够同时报告任意数量按键的键盘。
+
+## Oneshot Modifier(粘滞键)
+一种能让你的功能键一直保持按下，直到你按下其他键的功能。它叫做粘滞键或叫做粘连键，该功能由软件实现而非机械结构。
+
+## ProMicro
+一种低成本AVR开发板。这种板子很容易在购物网站找到(价格不到20RMB)，但是据说刷写pro micro有点令人抓狂。
+
+## Pull Request(拉请求、PR)
+向QMK请求提交代码。我们鼓励所有用户提交你们自己的键盘的代码。
+
+## QWERTY
+标准英文键盘，通常也用于其他语言，例如中文。是用键盘前6个字母命名的。
+
+## QWERTZ
+标准Deutsche(德语)键盘布局。使用前6个字母明名。
+
+## Rollover(允许翻转、无冲形式)
+该术语表示在一个键已按下时按下另一个键。形式包括2KRO(双键无冲),6KRO(6键无冲),和NKRO(全键无冲)，无冲表示可同时按下而不产生冲突的键的数量。
+
+## Scancode(扫描码)
+HID报告中的一个1字节的数字，表示一个键子。这些数字在下列文档中[HID Usage Tables](https://www.usb.org/sites/default/files/documents/hut1_12v2.pdf)该文档发布于[USB-IF](http://www.usb.org/)。
+
+## Space Cadet键盘的shift键
+一种特使的shift设置，能让你通过敲击左或右shift一次或多次键入不同的括号。
+
+* [Space Cadet键盘文档](feature_space_cadet.md)
+
+## Tap(敲击、单击)
+按下并释放一个键。在某些情况下您需要区分键按下和键抬起，但是单击把两个事件都包括了。
+
+## Tap Dance(多击键)
+本功能允许向同一个键子分配多个键码，并根据按键次数区分。
+
+* [多击键文档](feature_tap_dance.md)
+
+## Teensy
+一种低成本AVR开发板<!--译者吐槽：我怎么感觉成本不低。好吧，我穷。 -->，通常用于手工连线键盘。这个teensy是有点小贵但是halfkay bootloader会让它刷写十分简单，所以也很常用。
+
+## Underlight(背光)
+用于照亮电路板底面的LED的总称。这些LED通常从印刷电路板的底部向键盘所在的表面发光。
+
+## Unicode
+在较大的计算机世界中，Unicode是一组编码方案，用于表示任何语言中的字符。 与qmk相关的是，它意味着使用各种操作系统方案来发送Unicode代码点，而不是扫描码。
+
+* [Unicode文档](feature_unicode.md)
+
+## Unit Testing(单元测试)
+针对qmk的自动运行测试框架。单元测试帮助我们确信我们的更改不会破坏任何东西。
+
+* [单元测试文档](unit_testing.md)
+
+## USB
+通用串行总线，键盘最常见的有线接口。
+
+## USB 主机 (或简易主机)
+USB诸暨市你的电脑，或者你的键盘所插的任何设备。
+
+# 并没有找到你想找到的术语?
+
+[建立一个issue](https://github.com/qmk/qmk_firmware/issues) ，想好你的问题，或许你所问的术语就会添加到这里。创建一个PR帮我们添加需要添加的术语当然坠吼了:)

+ LCD character displays can be found in many devices, like espresso machines, laser printers.
+ The Hitachi HD44780 controller and its compatible controllers like Samsung KS0066U have become an industry standard for these types of displays.
+
  This library allows easy interfacing with a HD44780 compatible display and can be
- operated in memory mapped mode (LCD_IO_MODE defined as 0 in the include file lcd.h.) or in 
+ operated in memory mapped mode (LCD_IO_MODE defined as 0 in the include file lcd.h.) or in
  4-bit IO port mode (LCD_IO_MODE defined as 1). 8-bit IO port mode is not supported.
 
  Memory mapped mode is compatible with old Kanda STK200 starter kit, but also supports
  generation of R/W signal through A8 address line.
