+## How to Get It

 If you plan on contributing a keymap, keyboard, or features to QMK, the easiest thing to do is [fork the repo through Github](https://github.com/qmk/qmk_firmware#fork-destination-box), and clone your repo locally to make your changes, push them, then open a [Pull Request](https://github.com/qmk/qmk_firmware/pulls) from your fork.

 Otherwise, you can either download it directly ([zip](https://github.com/qmk/qmk_firmware/zipball/master), [tar](https://github.com/qmk/qmk_firmware/tarball/master)), or clone it via git (`git@github.com:qmk/qmk_firmware.git`), or https (`https://github.com/qmk/qmk_firmware.git`).

 QMK has lots of [features](features.md) to explore, and a good deal of [reference documentation](http://docs.qmk.fm) to dig through. Most features are taken advantage of by modifying your [keymap](keymap.md), and changing the [keycodes](keycodes.md).

+# Keyboard Idling/Wake Code
+
+If the board supports it, it can be "idled", by stopping a number of functions.  A good example of this is RGB lights or backlights.   This can save on power consumption, or may be better behavior for your keyboard.  
+
+This is controlled by two functions: `suspend_power_down_*` and `suspend_wakeup_init_*`, which are called when the system is board is idled and when it wakes up, respectively. 
+
+
+### Example suspend_power_down_user() and suspend_wakeup_init_user() Implementation

 # Switching and Toggling Layers

-These functions allow you to activate layers in various ways.
+These functions allow you to activate layers in various ways. Note that layers are not generally independent layouts -- multiple layers can be activated at once, and it's typical for layers to use `KC_TRNS` to allow keypresses to pass through to lower layers. For a detailed explanation of layers, see [Keymap Overview](keymap.md#keymap-and-layers)

-* `MO(layer)` - momentary switch to *layer*. As soon as you let go of the key, the layer is deactivated and you pop back out to the previous layer.
-* `LT(layer, kc)` - momentary switch to *layer* when held, and *kc* when tapped.
-* `TG(layer)` - toggles a layer on or off.
-* `TO(layer)` - Goes to a layer. This code is special, because it lets you go either up or down the stack -- just goes directly to the layer you want. So while other codes only let you go _up_ the stack (from layer 0 to layer 3, for example), `TO(2)` is going to get you to layer 2, no matter where you activate it from -- even if you're currently on layer 5. This gets activated on keydown (as soon as the key is pressed).
-* `TT(layer)` - Layer Tap-Toggle. If you hold the key down, the layer becomes active, and then deactivates when you let go. And if you tap it, the layer simply becomes active (toggles on). It needs 5 taps by default, but you can set it by defining `TAPPING_TOGGLE`, for example, `#define TAPPING_TOGGLE 2` for just two taps.
+* `DF(layer)` - switches the default layer. The default layer is the always-active base layer that other layers stack on top of. See below for more about the default layer. This might be used to switch from QWERTY to Dvorak layout. (Note that this is a temporary switch that only persists until the keyboard loses power. To modify the default layer in a persistent way requires deeper customization, such as calling the `set_single_persistent_default_layer` function inside of [process_record_user](custom_quantum_functions.md#programming-the-behavior-of-any-keycode).)
+* `MO(layer)` - momentarily activates *layer*. As soon as you let go of the key, the layer is deactivated. 
+* `LM(layer, mod)` - Momentarily activates *layer* (like `MO`), but with modifier(s) *mod* active. Only supports layers 0-15 and the left modifiers.
+* `LT(layer, kc)` - momentarily activates *layer* when held, and sends *kc* when tapped.
+* `TG(layer)` - toggles *layer*, activating it if it's inactive and vice versa
+* `TO(layer)` - activates *layer* and de-activates all other layers (except your default layer). This function is special, because instead of just adding/removing one layer to your active layer stack, it will completely replace your current active layers, uniquely allowing you to replace higher layers with a lower one. This is activated on keydown (as soon as the key is pressed).
+* `TT(layer)` - Layer Tap-Toggle. If you hold the key down, *layer* is activated, and then is de-activated when you let go (like `MO`). If you repeatedly tap it, the layer will be toggled on or off (like `TG`). It needs 5 taps by default, but you can change this by defining `TAPPING_TOGGLE` -- for example, `#define TAPPING_TOGGLE 2` to toggle on just two taps.

+* Setup layer 0 as your default, "base" layer. This is your normal typing layer, and could be whatever layout you want (qwerty, dvorak, colemak, etc.).

 Layers stack on top of each other in numerical order. When determining what a keypress does, QMK scans the layers from the top down, stopping when it reaches the first active layer that is not set to `KC_TRNS`. As a result if you activate a layer that is numerically lower than your current layer, and your current layer (or another layer that is active and higher than your target layer) has something other than `KC_TRNS`, that is the key that will be sent, not the key on the layer you just activated.

-# Mod Tap
+You can combine these by ORing them together like so:

-`MT(mod, kc)` - is *mod* (modifier key - MOD_LCTL, MOD_LSFT) when held, and *kc* when tapped. In other words, you can have a key that sends Esc (or the letter O or whatever) when you tap it, but works as a Control key or a Shift key when you hold it down.
+```c
+MT(MOD_LCTL | MOD_LSFT, KC_ESC)
+```

-These are the values you can use for the `mod` in `MT()` and `OSM()`:
+This key would activate Left Control and Left Shift when held, and send Escape when tapped.

-  * MOD_LCTL
-  * MOD_LSFT
-  * MOD_LALT
-  * MOD_LGUI
-  * MOD_RCTL
-  * MOD_RSFT
-  * MOD_RALT
-  * MOD_RGUI
-  * MOD_HYPR
-  * MOD_MEH
+For convenience, QMK includes some Mod-Tap shortcuts to make common combinations more compact in your keymap:

-These can also be combined like `MOD_LCTL | MOD_LSFT` e.g. `MT(MOD_LCTL | MOD_LSFT, KC_ESC)` which would activate Control and Shift when held, and send Escape when tapped. Note however, that you cannot mix right and left side modifiers.
-
-We've added shortcuts to make common modifier/tap (mod-tap) mappings more compact:
-
-  * `CTL_T(kc)` - is LCTL when held and *kc* when tapped
-  * `SFT_T(kc)` - is LSFT when held and *kc* when tapped
-  * `ALT_T(kc)` - is LALT when held and *kc* when tapped
-  * `ALGR_T(kc)` - is AltGr when held and *kc* when tapped
-  * `GUI_T(kc)` - is LGUI when held and *kc* when tapped
-  * `ALL_T(kc)` - is Hyper (all mods) when held and *kc* when tapped. To read more about what you can do with a Hyper key, see [this blog post by Brett Terpstra](http://brettterpstra.com/2012/12/08/a-useful-caps-lock-key/)
-  * `LCAG_T(kc)` - is CtrlAltGui when held and *kc* when tapped
-  * `MEH_T(kc)` - is like Hyper, but not as cool -- does not include the Cmd/Win key, so just sends Alt+Ctrl+Shift.

+# Mod tap interrupt
+
+When a dual role key used for a modifier is quickly followed by another keys, it is interpreted as held even before the tapping term elapsed.  This is a problem if a key is used for example inside a rolling combo because the second key will be pressed before the first key is released.
+
+For example, when trying to type the rolling combo "zx" and z being configured to send Ctrl when hold, z rapidly followed by x actually sends Ctrl-x. That's bad.

+# Retro Tapping
+
+When you hold a dual function key, and haven't pressed anything when you release the key, normally nothing happens.  However, if you enable this, if you release the key without pressing another key, it will send the original key, even if it is outside of the tapping term.

 # Backlighting

-<!-- FIXME: Describe how backlighting works in QMK -->
+Many keyboards support backlit keys by way of individual LEDs placed through or underneath the keyswitches. QMK is able to control the brightness of these LEDs by switching them on and off rapidly in a certain ratio, a technique known as *Pulse Width Modulation*, or PWM. By altering the duty cycle of the PWM signal, it creates the illusion of dimming.

-## Backlight Keycodes
+The MCU can only supply so much current to its GPIO pins. Instead of powering the backlight directly from the MCU, the backlight pin is connected to a transistor or MOSFET that switches the power to the LEDs.

-These keycodes control the backlight. Most keyboards use this for single color in-switch lighting.
+## Usage
+
+Most keyboards have backlighting enabled by default if they support it, but if it is not working for you, check that your `rules.mk` includes the following:
+
+```make
+BACKLIGHT_ENABLE = yes
+```
+
+You should then be able to use the keycodes below to change the backlight level.

-* `BACKLIGHT_BREATHING` if defined, enables backlight breathing. Note that this is only available if `BACKLIGHT_PIN` is B5, B6 or B7.
-* `BREATHING_PERIOD 6` defines the length of one backlight "breath" in seconds.
+Hardware PWM is only supported on certain pins of the MCU, so if the backlighting is not connected to one of them, a software implementation will be used, and backlight breathing will not be available. Currently the supported pins are `B5`, `B6`, `B7`, and `C6`.

-## Notes on Implementation
+## Configuration

-To change the brightness when using pins B5, B6 or B7, the PWM (Pulse Width Modulation) functionality of the on-chip timer is used.
-The timer is a counter that counts up to a certain TOP value (`0xFFFF` set in ICR1) before resetting to 0.
-We also set an OCR1x register.
-When the counter reaches the value stored in that register, the PWM pin drops to low.
-The PWM pin is pulled high again when the counter resets to 0.
-Therefore, OCR1x basically sets the duty cycle of the LEDs and as such the brightness where `0` is the darkest and `0xFFFF` the brightest setting.
+To change the behaviour of the backlighting, `#define` these in your `config.h`:

-To enable the breathing effect, we register an interrupt handler to be called whenever the counter resets (with `ISR(TIMER1_OVF_vect)`).
-In this handler, which gets called roughly 244 times per second, we compute the desired brightness using a precomputed brightness curve.
-To disable breathing, we can just disable the respective interrupt vector and reset the brightness to the desired level.

+
+## Hardware PWM Implementation
+
+When using the supported pins for backlighting, QMK will use a hardware timer configured to output a PWM signal. This timer will count up to `ICRx` (by default `0xFFFF`) before resetting to 0.
+The desired brightness is calculated and stored in the `OCRxx` register. When the counter reaches this value, the backlight pin will go low, and is pulled high again when the counter resets.
+In this way `OCRxx` essentially controls the duty cycle of the LEDs, and thus the brightness, where `0x0000` is completely off and `0xFFFF` is completely on.
+
+The breathing effect is achieved by registering an interrupt handler for `TIMER1_OVF_vect` that is called whenever the counter resets, roughly 244 times per second.
+In this handler, the value of an incrementing counter is mapped onto a precomputed brightness curve. To turn off breathing, the interrupt handler is simply disabled, and the brightness reset to the level stored in EEPROM.

 # Bootmagic

-<!-- FIXME: Describe the bootmagic feature here. -->
+There are three separate but related features that allow you to change the behavior of your keyboard without reflashing. While each of them have similar functionality, it is accessed in different ways depending on how your keyboard is configured.

-## Bootmagic Keycodes
+**Bootmagic** is a system for configuring your keyboard while it initializes. To trigger a Bootmagic command, hold down the Bootmagic key and one or more command keys.

-Shortcuts for bootmagic options. You can use these even when bootmagic is off.
+**Bootmagic Keycodes** are prefixed with `MAGIC_`, and allow you to access the Bootmagic functionality *after* your keyboard has initialized. To use the keycodes, assign them to your keymap as you would any other keycode.

-|Key                               |Aliases  |Description                         |

+**Command**, formerly known as **Magic**, is another feature that allows you to control different aspects of your keyboard. While it shares some functionality with Bootmagic, it also allows you to do things that Bootmagic does not, such as printing version information to the console. For more information, see [Command](feature_command.md).
+
+On some keyboards Bootmagic is disabled by default. If this is the case, it must be explicitly enabled in your `rules.mk` with:
+
+```make
+BOOTMAGIC_ENABLE = yes
+```
+
+## Hotkeys
+
+Hold down the Bootmagic key (Space by default) and the desired hotkey while plugging in your keyboard. For example, holding Space+`B` should cause it to enter the bootloader.

+# Command
+
+Command, formerly known as Magic, is a way to change your keyboard's behavior without having to flash or unplug it to use [Bootmagic](feature_bootmagic.md). There is a lot of overlap between this functionality and the [Bootmagic Keycodes](feature_bootmagic.md#keycodes). Wherever possible we encourage you to use that feature instead of Command.
+
+On some keyboards Command is disabled by default. If this is the case, it must be explicitly enabled in your `rules.mk`:
+
+```make
+COMMAND_ENABLE = yes
+```
+
+## Usage
+
+To use Command, hold down the key combination defined by the `IS_COMMAND()` macro. By default this is Left Shift+Right Shift. Then, press the key corresponding to the command you want. For example, to output the current QMK version to the QMK Toolbox console, press Left Shift+Right Shift+`V`.
+
+## Configuration
+
+If you would like to change the key assignments for Command, `#define` these in your `config.h` at either the keyboard or keymap level. All keycode assignments here must omit the `KC_` prefix.

 # Grave Escape

-Grave Escape is a feature that allows you to share the grave key (<code>&#96;</code> and `~`) on the same key as Escape. When `KC_GESC` is used it will act as `KC_ESC`, unless Shift or GUI is pressed, in which case it will act as `KC_GRAVE`.
+If you're using a 60% keyboard, or any other layout with no F-row, you will have noticed that there is no dedicated Escape key. Grave Escape is a feature that allows you to share the grave key (<code>&#96;</code> and `~`) with Escape.

+## Usage
+
+Replace the `KC_GRAVE` key in your keymap (usually to the left of the `1` key) with `KC_GESC`. When pressed it will behave like `KC_ESC`, but with Shift or GUI held it will send `KC_GRAVE`.
+
+## Keycodes

 |Key      |Aliases    |Description                                                       |

+# HD44780 LCD Displays
+
+This is an integration of Peter Fleury's LCD library. This page will explain the basics. [For in depth documentation visit his page.](http://homepage.hispeed.ch/peterfleury/doxygen/avr-gcc-libraries/group__pfleury__lcd.html)
+
+You can enable support for HD44780 Displays by setting the `HD44780_ENABLE` flag in your keyboards `rules.mk` to yes. This will use about 400 KB of extra space.
+
+## Configuration
+
+You will need to configure the pins used by your display and its number of lines and collumn in your keyboards `config.h`.
+
+Uncomment the section labled HD44780 and change the parameters as needed.
+````
+/*
+ * HD44780 LCD Display Configuration
+ */
+

+#define LCD_E_PIN        1            //< pin  for Enable line    
+#endif
+````
+
+Should you need to configure other properties you can copy them from `quantum/hd44780.h` and set them in your `config.h`
+
+## Usage 
+
+To initialize your display call lcd_init() with one of these parameters:
+````
+LCD_DISP_OFF             : display off
+LCD_DISP_ON              : display on, cursor off
+LCD_DISP_ON_CURSOR       : display on, cursor on
+LCD_DISP_ON_CURSOR_BLINK : display on, cursor on flashing 
+````
+This is best done in your keyboards `matrix_init_kb` or your keymaps `matrix_init_user`.  
+It is advised to clear the display before use.  
+To do so call `lcd_clrsrc()`.
+
+To now print something to your Display you first call `lcd_gotoxy(column, line)`. To go to the start of the first line you would call `lcd_gotoxy(0, 0)` and then print a string with `lcd_puts("example string")`.
+
+There are more posible methods to control the display. [For in depth documentation please visit the linked page.](http://homepage.hispeed.ch/peterfleury/doxygen/avr-gcc-libraries/group__pfleury__lcd.html)

-## Key Lock: Holding Down Keys for You
+# Key Lock

-Sometimes, you need to hold down a specific key for a long period of time. Whether this is while typing in ALL CAPS, or playing a video game that hasn't implemented auto-run, Key Lock is here to help. Key Lock adds a new keycode, `KC_LOCK`, that will hold down the next key you hit for you. The key is released when you hit it again. Here's an example: let's say you need to type in all caps for a few sentences. You hit KC_LOCK, and then shift. Now, shift will be considered held until you hit it again. You can think of key lock as caps lock, but supercharged.
+Sometimes you may find yourself needing to hold down a specific key for a long period of time. Key Lock holds down the next key you press for you. Press it again, and it will be released.

-Here's how to use it:
+Let's say you need to type in ALL CAPS for a few sentences. Hit `KC_LOCK`, and then Shift. Now, Shift will be considered held until you tap it again. You can think of Key Lock as Caps Lock, but supercharged.

-1. Pick a key on your keyboard. This will be the key lock key. Assign it the keycode `KC_LOCK`. This will be a single-action key: you won't be able to use it for anything else.
-2. Enable key lock by including `KEY_LOCK_ENABLE = yes` in your Makefile.
-3. That's it!
+## Usage

-Important: switching layers does not cancel the key lock. Additionally, key lock is only able to hold standard action keys and One Shot modifier keys (for example, if you have your shift defined as `OSM(KC_LSFT)`; see [One Shot Keys](quantum_keycodes.md#one-shot-keys)). This does not include any of the QMK special functions (except One Shot modifiers), or shifted versions of keys such as KC_LPRN. If it's in the [Basic Keycodes](keycodes_basic.md) list, it can be held. If it's not, then it can't be.
+First, enable Key Lock by setting `KEY_LOCK_ENABLE = yes` in your `rules.mk`. Then pick a key in your keymap and assign it the keycode `KC_LOCK`.
+
+## Keycodes
+
+|Keycode  |Description                                                   |
+|---------|--------------------------------------------------------------|
+|`KC_LOCK`|Hold down the next key pressed, until the key is pressed again|

+## Caveats

+Key Lock is only able to hold standard action keys and [One Shot modifier](quantum_keycodes.md#one-shot-keys) keys (for example, if you have your Shift defined as `OSM(KC_LSFT)`).

+## Driver configuration
+
+### IS31FL3731
+
+There is basic support for addressable RGB matrix lighting with the I2C IS31FL3731 RGB controller. To enable it, add this to your `rules.mk`:
+
+    RGB_MATRIX_ENABLE = IS31FL3731
+
+Configure the hardware via your `config.h`:
+
+	// This is a 7-bit address, that gets left-shifted and bit 0
+	// set to 0 for write, 1 for read (as per I2C protocol)
+	// The address will vary depending on your wiring:

+	// 0b1110111 AD <-> VCC
+	// 0b1110101 AD <-> SCL
+	// 0b1110110 AD <-> SDA
+	#define DRIVER_ADDR_1 0b1110100

+	#define DRIVER_1_LED_TOTAL 25
+	#define DRIVER_2_LED_TOTAL 24
+	#define DRIVER_LED_TOTAL DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL
+
+Currently only 2 drivers are supported, but it would be trivial to support all 4 combinations.
+
+Define these arrays listing all the LEDs in your `<keyboard>.c`:
+
+	const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
+	/* Refer to IS31 manual for these locations
+	 *   driver

+Where `Cx_y` is the location of the LED in the matrix defined by [the datasheet](http://www.issi.com/WW/pdf/31FL3731.pdf) and the header file `drivers/issi/is31fl3731.h`. The `driver` is the index of the driver you defined in your `config.h` (`0` or `1` right now).
+
+###  IS31FL3733
+
+There is basic support for addressable RGB matrix lighting with the I2C IS31FL3733 RGB controller. To enable it, add this to your `rules.mk`:
+
+    RGB_MATRIX_ENABLE = IS31FL3733

+	    ....
+	}
+
+The format for the matrix position used in this array is `{row | (col << 4)}`. The `x` is between (inclusive) 0-224, and `y` is between (inclusive) 0-64. The easiest way to calculate these positions is:
+
+    x = 224 / ( NUMBER_OF_ROWS - 1 ) * ROW_POSITION
+    y = 64 / (NUMBER_OF_COLS - 1 ) * COL_POSITION
+
+Where all variables are decimels/floats.
+
+`modifier` is a boolean, whether or not a certain key is considered a modifier (used in some effects).
+
+## Keycodes
+
+All RGB keycodes are currently shared with the RGBLIGHT system:
+
+	* `RGB_TOG` - toggle
+	* `RGB_MOD` - cycle through modes
+	* `RGB_HUI` - increase hue
+	* `RGB_HUD` - decrease hue
+	* `RGB_SAI` - increase saturation
+	* `RGB_SAD` - decrease saturation
+	* `RGB_VAI` - increase value
+	* `RGB_VAD` - decrease value
+	* `RGB_SPI` - increase speed effect (no EEPROM support)
+	* `RGB_SPD` - decrease speed effect (no EEPROM support)
+
+
+	* `RGB_MODE_*` keycodes will generally work, but are not currently mapped to the correct effects for the RGB Matrix system
+
+## RGB Matrix Effects
+
+These are the effects that are currently available:
+
+	enum rgb_matrix_effects {
+	    RGB_MATRIX_SOLID_COLOR = 1,
+	    RGB_MATRIX_ALPHAS_MODS,
+	    RGB_MATRIX_DUAL_BEACON,
+	    RGB_MATRIX_GRADIENT_UP_DOWN,
+	    RGB_MATRIX_RAINDROPS,
+	    RGB_MATRIX_CYCLE_ALL,
+	    RGB_MATRIX_CYCLE_LEFT_RIGHT,
+	    RGB_MATRIX_CYCLE_UP_DOWN,
+	    RGB_MATRIX_RAINBOW_BEACON,
+	    RGB_MATRIX_RAINBOW_PINWHEELS,
+	    RGB_MATRIX_RAINBOW_MOVING_CHEVRON,
+	    RGB_MATRIX_JELLYBEAN_RAINDROPS,
+	#ifdef RGB_MATRIX_KEYPRESSES
+	    RGB_MATRIX_SOLID_REACTIVE,
+	    RGB_MATRIX_SPLASH,
+	    RGB_MATRIX_MULTISPLASH,
+	    RGB_MATRIX_SOLID_SPLASH,
+	    RGB_MATRIX_SOLID_MULTISPLASH,
+	#endif
+	    RGB_MATRIX_EFFECT_MAX
+	};
+
+## Custom layer effects
+
+Custom layer effects can be done by defining this in your `<keyboard>.c`:
+
+    void rgb_matrix_indicators_kb(void) {
+        rgb_matrix_set_color(index, red, green, blue);
+    }
+
+A similar function works in the keymap as `rgb_matrix_indicators_user`.
+
+## Additional `config.h` Options
+
+	#define RGB_MATRIX_KEYPRESSES // reacts to keypresses (will slow down matrix scan by a lot)
+	#define RGB_MATRIX_KEYRELEASES // reacts to keyreleases (not recommened)
+	#define RGB_DISABLE_AFTER_TIMEOUT 0 // number of ticks to wait until disabling effects
+	#define RGB_DISABLE_WHEN_USB_SUSPENDED false // turn off effects when suspended
+    #define RGB_MATRIX_SKIP_FRAMES 1 // number of frames to skip when displaying animations (0 is full effect) if not defined defaults to 1
+    #define RGB_MATRIX_MAXIMUM_BRIGHTNESS 200 // limits maximum brightness of LEDs to 200 out of 255. If not defined maximum brightness is set to 255
+
+## EEPROM storage
+
+The EEPROM for it is currently shared with the RGBLIGHT system (it's generally assumed only one RGB would be used at a time), but could be configured to use its own 32bit address with:
+
+    #define EECONFIG_RGB_MATRIX (uint32_t *)16
+
+Where `16` is an unused index from `eeconfig.h`.
+
+## Suspended state
+
+To use the suspend feature, add this to your `<keyboard>.c`:
+
+	void suspend_power_down_kb(void)
+	{
+	    rgb_matrix_set_suspend_state(true);
+	}
+
+	void suspend_wakeup_init_kb(void)
+	{
+	    rgb_matrix_set_suspend_state(false);

 # RGB Lighting

-If you've installed addressable RGB lights on your keyboard you can control them with QMK. Currently we support the following addressable LEDs on Atmel AVR processors:
+QMK has the ability to control RGB LEDs attached to your keyboard. This is commonly called *underglow*, due to the LEDs often being mounted on the bottom of the keyboard, producing a nice diffused effect when combined with a translucent case.

+Some keyboards come with RGB LEDs preinstalled. Others must have them installed after the fact. See the [Hardware Modification](#hardware-modification) section for information on adding RGB lighting to your keyboard.

-## Selecting Colors
+Currently QMK supports the following addressable LEDs on AVR microcontrollers (however, the white LED in RGBW variants is not supported):

-QMK uses Hue, Saturation, and Value to set color rather than using RGB. You can use the color wheel below to see how this works. Changing the Hue will cycle around the circle. Saturation will affect the intensity of the color, which you can see as you move from the inner part to the outer part of the wheel. Value sets the overall brightness.

+ * SK6812, SK6812MINI, SK6805

-<img src="gitbook/images/color-wheel.svg" alt="HSV Color Wheel" width="250">
+These LEDs are called "addressable" because instead of using a wire per color, each LED contains a small microchip that understands a special protocol sent over a single wire. The chip passes on the remaining data to the next LED, allowing them to be chained together. In this way, you can easily control the color of the individual LEDs.

-If you would like to learn more about HSV you can start with the [Wikipedia article](https://en.wikipedia.org/wiki/HSL_and_HSV).
+## Usage

-## Configuration
+On keyboards with onboard RGB LEDs, it is usually enabled by default. If it is not working for you, check that your `rules.mk` includes the following:

-Before RGB Lighting can be used you have to enable it in `rules.mk`:
-
-    RGBLIGHT_ENABLE = yes
-
-You can configure the behavior of the RGB lighting by defining values inside `config.h`.
-
-### Required Configuration
-
-At minimum you have to define the pin your LED strip is connected to and the number of LEDs connected.
-
-```c
-#define RGB_DI_PIN D7     // The pin the LED strip is connected to
-#define RGBLED_NUM 14     // Number of LEDs in your strip
+```make
+RGBLIGHT_ENABLE = yes
 ```

-### Optional Configuration
+At minimum you must define the data pin your LED strip is connected to, and the number of LEDs in the strip, in your `config.h`. If your keyboard has onboard RGB LEDs, and you are simply creating a keymap, you usually won't need to modify these.

-You can change the behavior of the RGB Lighting by setting these configuration values. Use `#define <Option> <Value>` in a `config.h` at the keyboard, revision, or keymap level.
+|Define      |Description                                  |
+|------------|---------------------------------------------|
+|`RGB_DI_PIN`|The pin connected to the data pin of the LEDs|
+|`RGBLED_NUM`|The number of LEDs connected                 |

-| Option | Default Value | Description |
-|--------|---------------|-------------|
-| `RGBLIGHT_HUE_STEP` | 10 | How many hues you want to have available. |
-| `RGBLIGHT_SAT_STEP` | 17 | How many steps of saturation you'd like. |
-| `RGBLIGHT_VAL_STEP` | 17 | The number of levels of brightness you want. |
-| `RGBLIGHT_LIMIT_VAL` | 255 | Limit the val of HSV to limit the maximum brightness simply. |
+Then you should be able to use the keycodes below to change the RGB lighting to your liking.

-### Animations
+### Color Selection

-If you have `#define RGBLIGHT_ANIMATIONS` in your `config.h` you will have a number of animation modes you can cycle through using the `RGB_MOD` key. You can also `#define` other options to tweak certain animations.
+QMK uses [Hue, Saturation, and Value](https://en.wikipedia.org/wiki/HSL_and_HSV) to select colors rather than RGB. The color wheel below demonstrates how this works.

-| Option | Default Value | Description |
-|--------|---------------|-------------|
-| `RGBLIGHT_ANIMATIONS` | | `#define` this to enable animation modes. |
-| `RGBLIGHT_EFFECT_BREATHE_CENTER` | 1.85 | Used to calculate the curve for the breathing animation. Valid values 1.0-2.7. |
-| `RGBLIGHT_EFFECT_BREATHE_MAX` | 255 | The maximum brightness for the breathing mode. Valid values 1-255. |
-| `RGBLIGHT_EFFECT_SNAKE_LENGTH` | 4 | The number of LEDs to light up for the "snake" animation. |
-| `RGBLIGHT_EFFECT_KNIGHT_LENGTH` | 3 | The number of LEDs to light up for the "knight" animation. |
-| `RGBLIGHT_EFFECT_KNIGHT_OFFSET` | 0 | Start the knight animation this many LEDs from the start of the strip. |
-| `RGBLIGHT_EFFECT_KNIGHT_LED_NUM` | RGBLED_NUM | The number of LEDs to have the "knight" animation travel. |
-| `RGBLIGHT_EFFECT_CHRISTMAS_INTERVAL` | 1000 | How long to wait between light changes for the "christmas" animation. Specified in ms. |
-| `RGBLIGHT_EFFECT_CHRISTMAS_STEP` | 2 | How many LED's to group the red/green colors by for the christmas mode. |
+<img src="gitbook/images/color-wheel.svg" alt="HSV Color Wheel" width="250"/>

-You can also tweak the behavior of the animations by defining these consts in your `keymap.c`. These mostly affect the speed different modes animate at.
+Changing the **Hue** cycles around the circle.  
+Changing the **Saturation** moves between the inner and outer sections of the wheel, affecting the intensity of the color.  
+Changing the **Value** sets the overall brightness.

-```c
-// How long (in ms) to wait between animation steps for the breathing mode
-const uint8_t RGBLED_BREATHING_INTERVALS[] PROGMEM = {30, 20, 10, 5};
-
-// How long (in ms) to wait between animation steps for the rainbow mode
-const uint8_t RGBLED_RAINBOW_MOOD_INTERVALS[] PROGMEM = {120, 60, 30};
-
-// How long (in ms) to wait between animation steps for the swirl mode
-const uint8_t RGBLED_RAINBOW_SWIRL_INTERVALS[] PROGMEM = {100, 50, 20};
-
-// How long (in ms) to wait between animation steps for the snake mode
-const uint8_t RGBLED_SNAKE_INTERVALS[] PROGMEM = {100, 50, 20};
-
-// How long (in ms) to wait between animation steps for the knight modes
-const uint8_t RGBLED_KNIGHT_INTERVALS[] PROGMEM = {127, 63, 31};
-
-// These control which colors are selected for the gradient mode
-const uint16_t RGBLED_GRADIENT_RANGES[] PROGMEM = {360, 240, 180, 120, 90};
-```
-
-### LED Control
-
-Look in `rgblights.h` for all available functions, but if you want to control all or some LEDs your goto functions are:
-
-```c
-rgblight_disable();  // turn all lights off
-rgblight_enable();  // turn lights on, based on their previous state (stored in EEPROM)
-
-rgblight_setrgb(r, g, b);  // where r/g/b is a number from 0..255.  Turns all the LEDs to this color
-rgblight_sethsv(h, s, v);  // HSV color control
-rgblight_setrgb_at(r,g,b, LED);  // control a single LED.  0 <= LED < RGBLED_NUM
-rgblight_sethsv_at(h,s,v, LED);  // control a single LED.  0 <= LED < RGBLED_NUM

 ## Hardware Modification

-![Planck with RGB Underglow](https://raw.githubusercontent.com/qmk/qmk_firmware/master/keyboards/planck/keymaps/yang/planck-with-rgb-underglow.jpg)
-
-Here is a quick demo on Youtube (with NPKC KC60) (https://www.youtube.com/watch?v=VKrpPAHlisY).
-
-For this mod, you need an unused pin wiring to DI of WS2812 strip. After wiring the VCC, GND, and DI, you can enable the underglow in your Makefile.
-
-    RGBLIGHT_ENABLE = yes
-
-In order to use the underglow animation functions, you need to have `#define RGBLIGHT_ANIMATIONS` in your `config.h`.
-
-Please add the following options into your config.h, and set them up according your hardware configuration. These settings are for the `F4` pin by default:
-
-    #define RGB_DI_PIN F4     // The pin your RGB strip is wired to
-    #define RGBLED_NUM 14     // Number of LEDs
-
-You'll need to edit `RGB_DI_PIN` to the pin you have your `DI` on your RGB strip wired to.
+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.

-## Space Cadet Shift: The Future, Built In

-Steve Losh [described](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/) the Space Cadet Shift quite well. Essentially, you hit the left Shift on its own, and you get an opening parenthesis; hit the right Shift on its own, and you get the closing one. When hit with other keys, the Shift key keeps working as it always does. Yes, it's as cool as it sounds.
-
-To use it, use `KC_LSPO` (Left Shift, Parenthesis Open) for your left Shift on your keymap, and `KC_RSPC` (Right Shift, Parenthesis Close) for your right Shift.
-
-It's defaulted to work on US keyboards, but if your layout uses different keys for parenthesis, you can define those in your `config.h` like this:
-
-    #define LSPO_KEY KC_9
-    #define RSPC_KEY KC_0
-
-You can also choose between different rollover behaviors of the shift keys by defining:
-
-    #define DISABLE_SPACE_CADET_ROLLOVER
-
-in your `config.h`. Disabling rollover allows you to use the opposite shift key to cancel the space cadet state in the event of an erroneous press instead of emitting a pair of parentheses when the keys are released.
-
-The only other thing you're going to want to do is create a `Makefile` in your keymap directory and set the following:
-
-```
-COMMAND_ENABLE   = no  # Commands for debug and configuration
-```
-
-This is just to keep the keyboard from going into command mode when you hold both Shift keys at the same time.

+# Space Cadet Shift: The Future, Built In
+
+Steve Losh described the [Space Cadet Shift](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/) quite well. Essentially, when you tap Left Shift on its own, you get an opening parenthesis; tap Right Shift on its own and you get the closing one. When held, the Shift keys function as normal. Yes, it's as cool as it sounds.
+
+## Usage
+
+Replace the Left Shift key in your keymap with `KC_LSPO` (Left Shift, Parenthesis Open), and Right Shift with `KC_RSPC` (Right Shift, Parenthesis Close).
+
+## Keycodes
+
+|Keycode  |Description                           |
+|---------|--------------------------------------|
+|`KC_LSPO`|Left Shift when held, `(` when tapped |
+|`KC_RSPC`|Right Shift when held, `)` when tapped|
+
+## Caveats
+
+Space Cadet's functionality can conflict with the default Command functionality when both Shift keys are held at the same time. Make sure that Command is disabled in your `rules.mk` with:
+
+```make
+COMMAND_ENABLE = no
+```
+
+## Configuration
+
+By default Space Cadet assumes a US ANSI layout, but if your layout uses different keys for parentheses, you can redefine them in your `config.h`.
+You can also disable the rollover, allowing you to use the opposite Shift key to cancel the Space Cadet state in the event of an erroneous press, instead of emitting a pair of parentheses when the keys are released.

+# Space Cadet Shift Enter
+
+Based on the [Space Cadet Shift](feature_space_cadet_shift.md) feature. Tap the Shift key on its own, and it behaves like Enter. When held, the Shift functions as normal.
+
+## Usage
+
+Replace any Shift key in your keymap with `KC_SFTENT` (Shift, Enter), and you're done.
+

+## Caveats
+
+As with Space Cadet Shift, this feature may conflict with Command, so it should be disabled in your `rules.mk` with:
+
+```make
+COMMAND_ENABLE = no
+```
+
+This feature also uses the same timers as Space Cadet Shift, so using them in tandem may produce strange results.
+
+## Configuration
+
+By default Space Cadet assumes a US ANSI layout, but if you'd like to use a different key for Enter, you can redefine it in your `config.h`:

 * More resources at the Plover [Learning Stenography](https://github.com/openstenoproject/plover/wiki/Learning-Stenography) wiki

+## Interfacing with the code
+
+The steno code has three interceptible hooks. If you define these functions, they will be called at certain points in processing; if they return true, processing continues, otherwise it's assumed you handled things.
+
+```C
+bool send_steno_chord_user(steno_mode_t mode, uint8_t chord[6]);
+```
+
+This function is called when a chord is about to be sent. Mode will be one of `STENO_MODE_BOLT` or `STENO_MODE_GEMINI`. This represents the actual chord that would be sent via whichever protocol. You can modify the chord provided to alter what gets sent. Remember to return true if you want the regular sending process to happen.
+
+```C
+bool process_steno_user(uint16_t keycode, keyrecord_t *record) { return true; }
+```
+
+This function is called when a keypress has come in, before it is processed. The keycode should be one of `QK_STENO_BOLT`, `QK_STENO_GEMINI`, or one of the `STN_*` key values.
+
+```C
+bool postprocess_steno_user(uint16_t keycode, keyrecord_t *record, steno_mode_t mode, uint8_t chord[6], int8_t pressed);
+```
+
+This function is called after a key has been processed, but before any decision about whether or not to send a chord. If `IS_PRESSED(record->event)` is false, and `pressed` is 0 or 1, the chord will be sent shortly, but has not yet been sent. This is where to put hooks for things like, say, live displays of steno chords or keys.

+# Swap-Hands Action
+
+The swap-hands action allows support for one-handed typing without requiring a separate layer. Set `SWAP_HANDS_ENABLE` in the Makefile and define a `hand_swap_config` entry in your keymap. Now whenever the `ACTION_SWAP_HANDS` command key is pressed the keyboard is mirrored. For instance, to type "Hello, World" on QWERTY you would type `^Ge^s^s^w^c W^wr^sd`
+
+## Configuration
+
+The configuration table is a simple 2-dimensional array to map from column/row to new column/row. Example `hand_swap_config` for Planck:
+
+```C
+const keypos_t hand_swap_config[MATRIX_ROWS][MATRIX_COLS] = {
+  {{11, 0}, {10, 0}, {9, 0}, {8, 0}, {7, 0}, {6, 0}, {5, 0}, {4, 0}, {3, 0}, {2, 0}, {1, 0}, {0, 0}},
+  {{11, 1}, {10, 1}, {9, 1}, {8, 1}, {7, 1}, {6, 1}, {5, 1}, {4, 1}, {3, 1}, {2, 1}, {1, 1}, {0, 1}},
+  {{11, 2}, {10, 2}, {9, 2}, {8, 2}, {7, 2}, {6, 2}, {5, 2}, {4, 2}, {3, 2}, {2, 2}, {1, 2}, {0, 2}},
+  {{11, 3}, {10, 3}, {9, 3}, {8, 3}, {7, 3}, {6, 3}, {5, 3}, {4, 3}, {3, 3}, {2, 3}, {1, 3}, {0, 3}},
+};
+```
+
+Note that the array indices are reversed same as the matrix and the values are of type `keypos_t` which is `{col, row}` and all values are zero-based. In the example above, `hand_swap_config[2][4]` (third row, fifth column) would return `{7, 2}` (third row, eighth column). Yes, this is confusing.

 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.

 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:

 * `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).
 * `ACTION_TAP_DANCE_FN(fn)`: Calls the specified function - defined in the user keymap - with the final tap count of the tap dance action.
-* `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 on when the dance action finishes (like the previous option), and the last function when the tap dance action resets.

+## Setup
+
+You will need a few things that can be used for 'Quad Function Tap-Dance'. The suggested setup is to create a user directory for yourself. This directory will contain rules.mk `<your_name>.c` and `<your_name>.h`. This directory should be called `<your_name>`, and located in the top level `users` directory. There should already be a few examples to look at there.

+### In `/qmk_firmware/users/<your_name>/rules.mk`
+
+Put the following:
 ```c
-//**************** Definitions needed for quad function to work *********************//
-//Enums used to clearly convey the state of the tap dance
-enum {
-  SINGLE_TAP = 1,
-  SINGLE_HOLD = 2,
-  DOUBLE_TAP = 3,
-  DOUBLE_HOLD = 4,
-  DOUBLE_SINGLE_TAP = 5 //send SINGLE_TAP twice - NOT DOUBLE_TAP
-  // Add more enums here if you want for triple, quadruple, etc.

+TAP_DANCE_ENABLE = yes

+ * How to figure out tap dance state: interrupted and pressed.
+ *
+ * Interrupted: If the state of a dance dance is "interrupted", that means that another key has been hit
+ *  under the tapping term. This is typically indicitive that you are trying to "tap" the key.
+ *
+ * Pressed: Whether or not the key is still being pressed. If this value is true, that means the tapping term
+ *  has ended, but the key is still being pressed down. This generally means the key is being "held".
+ *
+ * One thing that is currenlty not possible with qmk software in regards to tap dance is to mimic the "permissive hold"
+ *  feature. In general, advanced tap dances do not work well if they are used with commonly typed letters.
+ *  For example "A". Tap dances are best used on non-letter keys that are not hit while typing letters.
+ *
+ * Good places to put an advanced tap dance:
+ *  z,q,x,j,k,v,b, any function key, home/end, comma, semi-colon
+ *
+ * Criteria for "good placement" of a tap dance key:
+ *  Not a key that is hit frequently in a sentence
+ *  Not a key that is used frequently to double tap, for example 'tab' is often double tapped in a terminal, or
+ *    in a web form. So 'tab' would be a poor choice for a tap dance.
+ *  Letters used in common words as a double. For example 'p' in 'pepper'. If a tap dance function existed on the
+ *    letter 'p', the word 'pepper' would be quite frustating to type.
+ *
+ * For the third point, there does exist the 'DOUBLE_SINGLE_TAP', however this is not fully tested

+Additionally, `config.h` here will be processed like the same file in your keymap folder.  This is handled separately from the `<name>.h` file.
+
+The reason for this, is that `<name>.h` won't be added in time to add settings (such as `#define TAPPING_TERM 100`), and including the `<name.h>` file in any `config.h` files will result in compile issues.
+
+So you should use the `config.h` for QMK settings, and the `<name>.h` file for user or keymap specific settings.
+
+`/users/<name>/rules.mk` will be included in the build _after_ the `rules.mk` from your keymap. This allows you to have features in your userspace `rules.mk` that depend on individual QMK features that may or may not be available on a specific keyboard. For example, if you have RGB control features shared between all your keyboards that support RGB lighting, you can `define RGB_ENABLE` in your keymap `rules.mk` and then check for the variable in your userspace `rules.mk` like this:
+```make
+ifdef RGB_ENABLE
+    # Include my fancy rgb functions source here
+endif
+```
+Because of this, any time you turn on QMK features in your `users/<name>/rules.mk`, you should conditionally enable them only if the flag isn't already defined, like this:
+```make
+ifndef TAP_DANCE_ENABLE
+    TAP_DANCE_ENABLE = yes
+endif
+```
+This will ensure that you can explicitly turn off features for an individual keymap.

And this will work with any keyboard and any keymap as it will output the current boards info, so that you don't have to type this out every time.

 Additionally, this should flash the newly compiled firmware automatically, using the correct utility, based on the bootloader settings (or default to just generating the HEX file).

 Any sort of hardware file (plate, case, pcb) can't be stored in qmk_firmware, but we have the [qmk.fm repo](https://github.com/qmk/qmk.fm) where such files (as well as in-depth info) can be stored and viewed on [qmk.fm](http://qmk.fm). Downloadable files are stored in `/<keyboard>/` (name follows the same format as above) which are served at `http://qmk.fm/<keyboard>/`, and pages are generated from `/_pages/<keyboard>/` which are served at the same location (.md files are generated into .html files through Jekyll). Check out the `lets_split` directory for an example.

+## Keyboard Defaults
+
+Given the amount of functionality that QMK exposes it's very easy to confuse new users. When putting together the default firmware for your keyboard we recommend limiting your enabled features and options to the minimal set needed to support your hardware. Recommendations for specific features follow.
+
+### Bootmagic and Command
+
+[Bootmagic](feature_bootmagic.md) and [Command](feature_command.md) are two related features that allow a user to control their keyboard in non-obvious ways. We recommend you think long and hard about if you're going to enable either feature, and how you will expose this functionality. Keep in mind that users who want this functionality can enable it in their personal keymaps without affecting all the novice users who may be using your keyboard as their first programmable board.
+
+By far the most common problem new users encounter is accidentally triggering Bootmagic while they're plugging in their keyboard. They're holding the keyboard by the bottom, unknowingly pressing in alt and spacebar, and then they find that these keys have been swapped on them. We recommend leaving this feature disabled by default, but if you do turn it on consider setting `BOOTMAGIC_KEY_SALT` to a key that is hard to press while plugging your keyboard in.
+
+If your keyboard does not have 2 shift keys you should provide a working default for `IS_COMMAND`, even when you have set `COMMAND_ENABLE = no`. This will give your users a default to conform to if they do enable Command.
+
+## Custom Keyboard Programming
+
+As documented on [Customizing Functionality](custom_quantum_functions.md) you can define custom functions for your keyboard. Please keep in mind that your users may want to customize that behavior as well, and make it possible for them to do that. If you are providing a custom function, for example `process_record_kb()`, make sure that your function calls the `_user()` version of the call too. You should also take into account the return value of the `_user()` version, and only run your custom code if the user returns `true`.

+
+You use the functions when you are implementing your own midi device.
+
+You set a send function to actually send bytes via your device, this method is called when you call a send function with this device, for instance midi_send_cc
+
+You use the midi_device_input to process input data from the device and pass it through the device's associated callbacks.
+
+You use the midi_device_set_pre_input_process_func if you want to have a function called at the beginning of the device's process function, generally to poll for input and pass that into midi_device_input

 ## Software Needed

-* [The Arduino IDE](https://www.arduino.cc/en/Main/Software)
-* [Teensyduino](https://www.pjrc.com/teensy/td_download.html) (if you're using a Teensy)
-* [WinAVR](http://www.ladyada.net/learn/avr/setup-win.html) (Windows)
+* [Teensy Loader](https://www.pjrc.com/teensy/loader.html) (if using a Teensy)
+* QMK Toolbox (flash as usual - be sure to select the correct MCU) or `avrdude` via [WinAVR](http://www.ladyada.net/learn/avr/setup-win.html) (for Teensy & Pro Micro)

 ## Wiring

 This is pretty straight-forward - we'll be connecting like-things to like-things in the following manner:

-    Flasher B0  <-> Keyboard RESET
-    Flasher B1  <-> Keyboard B1 (SCLK)
-    Flasher B2  <-> Keyboard B2 (MOSI)
-    Flasher B3  <-> Keyboard B3 (MISO)
-    Flasher VCC <-> Keyboard VCC
-    Flasher GND <-> Keyboard GND
+### Teensy 2.0

-## The ISP Firmware
+    Teensy B0  <-> Keyboard RESET
+    Teensy B1  <-> Keyboard B1 (SCLK)
+    Teensy B2  <-> Keyboard B2 (MOSI)
+    Teensy B3  <-> Keyboard B3 (MISO)
+    Teensy VCC <-> Keyboard VCC
+    Teensy GND <-> Keyboard GND
+    
+### Pro Micro
+
+    Pro Micro 10 (B6)  <-> Keyboard RESET
+    Pro Micro 15 (B1)  <-> Keyboard B1 (SCLK)
+    Pro Micro 16 (B2)  <-> Keyboard B2 (MOSI)
+    Pro Micro 14 (B3)  <-> Keyboard B3 (MISO)
+    Pro Micro VCC      <-> Keyboard VCC
+    Pro Micro GND      <-> Keyboard GND
+
+## The ISP Firmware (now pre-compiled)
+
+The only difference between the .hex files below is which pin is connected to RESET. You can use them on other boards as well, as long as you're aware of the pins being used. If for some reason neither of these pins are available, [create an issue](https://github.com/qmk/qmk_firmware/issues/new), and we can generate one for you!
+
+* Teensy 2.0: [`util/teensy_2.0_ISP_B0.hex`](https://github.com/qmk/qmk_firmware/blob/master/util/teensy_2.0_ISP_B0.hex) (`B0`)
+* Pro Micro: [`util/pro_micro_ISP_B6_10.hex`](https://github.com/qmk/qmk_firmware/blob/master/util/pro_mico_ISP_B6_10.hex) (`B6/10`)
+
+**Flash your Teenys/Pro Micro with one of these and continue - you won't need the file after flashing your ISP device.**
+
+## Just the Bootloader File
+
+If you just want to get things back to normal, you can flash only a bootloader from [`util/` folder](https://github.com/qmk/qmk_firmware/tree/master/util), and use your normal process to flash the firmware afterwards. Be sure to flash the correct bootloader for your chip:
+
+* [`atmega32u4`](https://github.com/qmk/qmk_firmware/blob/master/util/bootloader_atmega32u4_1_0_0.hex) - Most keyboards, Planck Rev 1-5, Preonic Rev 1-2
+* [`at90usb1286`](https://github.com/qmk/qmk_firmware/blob/master/util/bootloader_at90usb128x_1_0_1.hex) - Planck Light Rev 1
+
+If you're not sure what your board uses, look in the `rules.mk` file for the keyboard in QMK. The `MCU =` line will have the value you need. It may differ between different versions of the board.
+
+### Advanced/Production Techniques
+
+If you'd like to flash both the bootloader **and** the regular firmware at the same time, you need to combine the files. 
+
+1. Open the original firmware .hex file in a text editor
+2. Remove the last line (which should be `:00000001FF` - this is an EOF message)
+3. Copy the entire bootloader's contents onto a new line (with no empty lines between) and paste it at the end of the original file
+4. Save it as a new file by naming it `<keyboard>_<keymap>_production.hex`
+
+It's possible to use other bootloaders here in the same way, but __you need a bootloader__, otherwise you'll have to use ISP again to write new firmware to your keyboard.
+
+## Flashing Your Bootloader/Production File

 Make sure your keyboard is unplugged from any device, and plug in your Teensy.

-1. Run Arduino after you have everything installed
-2. Select `Tools > Board * > Teensy 2.0`
-3. Click `File > Examples > 11.ArduinoISP > ArduinoISP`
+### QMK Toolbox

-Then scroll down until you see something that looks like this block of code:
+1. `AVRISP device connected` will show up in yellow
+2. Select the correct bootloader/production .hex file with the `Open` dialog (spaces can't be in the path)
+3. Be sure the correct `Microcontroller` option is selected
+4. Hit `Flash`
+5. Wait, as nothing will output for a while, especially with production files

-    // Configure which pins to use:
+If the verification and fuse checks are ok, you're done! Your board may restart automatically, otherwise, unplug your Teensy and plug in your keyboard - you can leave your Teensy wired to your keyboard while testing things, but it's recommended that you desolder it/remove the wiring once you're sure everything works.

-    // The standard pin configuration.
-    #ifndef ARDUINO_HOODLOADER2
-
-    #define RESET     0  // Use 0 (B0) instead of 10
-    #define LED_HB    11 // Use 11 (LED on the Teensy 2.0)
-    #define LED_ERR   8  // This won't be used unless you have an LED hooked-up to 8 (D3)
-    #define LED_PMODE 7  // This won't be used unless you have an LED hooked-up to 7 (D2)
-
-And make the changes in the last four lines. If you're using something besides the Teensy 2.0, you'll want to choose something else that makes sense for `LED_HB`. We define `RESET` as `0`/`B0` because that's what's close - if you want to use another pin for some reason, [you can use the pinouts to choose something else](https://www.pjrc.com/teensy/pinout.html).
-
-Once you've made your changes, you can click the Upload button (right arrow), which will open up the Teensy flasher app - you'll need to press the reset button on the Teensy the first time, but after that, it's automatic (you shouldn't be flashing this more than once, though). Once flashed, the orange LED on the Teensy will flash on and off, indicating it's ready for some action.
-
-## The `.hex` File
-
-Before flashing your firmware, you're going to need to and do a little preparation. We'll be appending [this bootloader (also a .hex file)](https://github.com/qmk/qmk_firmware/blob/master/util/bootloader_atmega32u4_1_0_0.hex) to the end of our firmware by opening the original .hex file in a text editor, and removing the last line, which should be `:00000001FF` (this is an EOF message). After that's been removed, copy the entire bootloader's contents and paste it at the end of the original file, and save it.
-
-It's possible to use other bootloaders here in the same way, but __you need a bootloader__, otherwise you'll have to ISP to write new firmware to your keyboard.
-
-## Flashing Your Firmware
-
-Make sure your keyboard is unplugged from any device, and plug in your Teensy.
+### Command Line

 Open `cmd` and navigate to your where your modified .hex file is. We'll pretend this file is called `main.hex`, and that your Teensy 2.0 is on the `COM3` port - if you're unsure, you can open your Device Manager, and look for `Ports > USB Serial Device`. Use that COM port here. You can confirm it's the right port with:

+These keycodes correspond to characters that are "shifted" on a standard US ANSI keyboard. They do not have keycodes of their own but are simply shortcuts for `LSFT(kc)`, and as such send a Left Shift with the unshifted keycode, not the symbol itself.

-It's important to remember that all of these keycodes send a left shift - this may cause unintended actions if unaccounted for. The short code is preferred in most situations.

 To actually handle the keypress event we define an `action_function()`. This function will be called when the key is pressed, and then again when the key is released. We have to handle both situations within our code, as well as determining whether to send/release `KC_ESC` or `KC_GRAVE`.

+# Building Your First Firmware
+
+Now that you have setup your build environment you are ready to start building custom firmware. For this section of the guide we will bounce between 3 programs- your file manager, your text editor, and your terminal window. Keep all 3 open until you are done and happy with your keyboard firmware.
+
+If you have closed and reopened your terminal window since following the first part of the guide, don't forget to `cd qmk_firmware` so that your terminal is in the correct directory.
+
+## Navigate To Your Keymaps Folder
+
+Start by navigating to the `keymaps` folder for your keyboard.
+
+?> If you are on macOS or Windows there are commands you can use to easily open the keymaps folder.
+
+?> macOS:
+
+    open keyboards/<keyboard_folder>/keymaps
+
+?> Windows:
+
+    start keyboards/<keyboard_folder>/keymaps
+
+## Create a Copy Of The `default` Keymap
+
+Once you have the `keymaps` folder open you will want to create a copy of the `default` folder. We highly recommend you name your folder the same as your GitHub username, but you can use any name you want as long as it contains only lower case letters, numbers, and the underscore character.
+
+To automate the process, you also have the option to run the `new_keymap.sh` script. 
+
+Navigate to the `qmk_firmware/util` directory and type the following:
+
+```
+./new_keymap.sh <keyboard path> <username>
+```
+
+For example, for a user named John, trying to make a new keymap for the 1up60hse, they would type in
+
+```
+./new_keymap.sh 1upkeyboards/1up60hse john
+```
+
+## Open `keymap.c` In Your Favorite Text Editor
+
+Open up your `keymap.c`. Inside this file you'll find the structure that controls how your keyboard behaves. At the top of `keymap.c` there may be some defines and enums that make the keymap easier to read. Farther down you'll find a line that looks like this:
+
+    const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {
+
+This line indicates the start of the list of Layers. Below that you'll find lines containing either `LAYOUT` or `KEYMAP`, and these lines indicate the start of a layer. Below that line is the list of keys that comprise a that particular layer.
+
+!> When editing your keymap file be careful not to add or remove any commas. If you do you will prevent your firmware from compiling and it may not be easy to figure out where the extra, or missing, comma is.
+
+## Customize The Layout To Your Liking
+
+How to complete this step is entirely up to you. Make the one change that's been bugging you, or completely rework everything. You can remove layers if you don't need all of them, or add layers up to a total of 32. Check the following documentation to find out what you can define here:
+
+* [Keycodes](keycodes.md)
+* [Features](features.md)
+* [FAQ](faq.md)
+
+?> While you get a feel for how keymaps work, keep each change small. Bigger changes make it harder to debug any problems that arise.
+
+## Build Your Firmware
+
+When your changes to the keymap are complete you will need to build the firmware. To do so go back to your terminal window and run the build command:
+
+    make <my_keyboard>:<my_keymap>
+
+For example, if your keymap is named "xyverz" and you're building a keymap for a rev5 planck, you'll use this command:
+
+    make planck/rev5:xyverz
+
+While this compiles you will have a lot of output going to the screen informing you of what files are being compiled. It should end with output that looks similar to this:
+
+```
+Linking: .build/planck_rev5_xyverz.elf                                                              [OK]
+Creating load file for flashing: .build/planck_rev5_xyverz.hex                                      [OK]
+Copying planck_rev5_xyverz.hex to qmk_firmware folder                                               [OK]
+Checking file size of planck_rev5_xyverz.hex                                                        [OK]
+ * File size is fine - 18392/28672
+```
+
+## Flash Your Firmware

+# Flashing Your Keyboard 
+
+Now that you've built a custom firmware file you'll want to flash your keyboard. 
+
+## Flashing Your Keyboard with QMK Toolbox
+
+The simplest way to flash your keyboard will be with the [QMK Toolbox](https://github.com/qmk/qmk_toolbox/releases). 
+
+However, the QMK Toolbox is only available for Windows and macOS currently.  If you're using Linux (or just wish to flash the firmware from the command line), you'll have to use the [method outlined below](newbs_flashing.md#flash-your-keyboard-from-the-command-line).
+
+### Load The File Into QMK Toolbox
+
+Begin by opening the QMK Toolbox application. You'll want to locate the firmware file in Finder or Explorer. Your keyboard firmware may be in one of two formats- `.hex` or `.bin`. QMK tries to copy the appropriate one for your keyboard into the root `qmk_firmware` directory.
+
+?> If you are on Windows or macOS there are commands you can use to easily open the current firmware folder in Explorer or Finder.
+
+?> Windows:
+
+    start .
+
+?> macOS:
+
+    open .
+
+The firmware file always follows this naming format:
+
+    <keyboard_name>_<keymap_name>.{bin,hex}
+
+For example, the `plank/rev5` with a `default` keymap will have this filename:
+
+    planck_rev5_default.hex
+
+Once you have located your firmware file drag it into the "Local file" box in QMK Toolbox, or click "Open" and navigate to where your firmware file is stored. 
+
+### Put Your Keyboard Into DFU (Bootloader) Mode
+
+In order to flash your custom firmware you have to put your keyboard into a special flashing mode. While it is in this mode you will not be able to type or otherwise use your keyboard. It is very important that you do not unplug your keyboard or otherwise interrupt the flashing process while the firmware is being written.
+
+Different keyboards have different ways to enter this special mode. If your PCB currently runs QMK or TMK and you have not been given specific instructions try the following, in order:
+
+* Hold down both shift keys and press `Pause`
+* Hold down both shift keys and press `B`
+* Unplug your keyboard, hold down the Spacebar and `B` at the same time, plug in your keyboard and wait a second before releasing the keys
+* Press the physical `RESET` button on the bottom of the PCB
+* Locate header pins on the PCB labeled `BOOT0` or `RESET`, short those together while plugging your PCB in
+
+When you are successful you will see a message similar to this in QMK Toolbox:
+
+```
+*** Clueboard - Clueboard 66% HotSwap disconnected -- 0xC1ED:0x2390
+*** DFU device connected
+```
+
+### Flash Your Keyboard
+
+Click the `Flash` button in QMK Toolbox. You will see output similar to the following:
+
+```
+*** Clueboard - Clueboard 66% HotSwap disconnected -- 0xC1ED:0x2390
+*** DFU device connected
+*** Attempting to flash, please don't remove device

+    
+*** DFU device disconnected
+*** Clueboard - Clueboard 66% HotSwap connected -- 0xC1ED:0x2390
+```
+
+## Flash your Keyboard from the Command Line
+
+First thing you'll need to know is which bootloader that your keyboard uses.  There are four main bootloaders that are used, usually. Pro-Micro and clones use CATERINA, and Teensy's use Halfkay, OLKB boards use QMK-DFU, and other atmega32u4 chips use DFU. 
+
+You can find more information about the bootloaders in the [Flashing Instructions and Bootloader Information](flashing.md) page. 
+
+If you know what bootloader that you're using, then when compiling the firmware, you can actually add some extra text to the `make` command to automate the flashing process. 
+
+### DFU
+
+For the DFU bootloader, when you're ready to compile and flash your firmware, open up your terminal window and run the built command: 
+
+    make <my_keyboard>:<my_keymap>:dfu
+
+For example, if your keymap is named "xyverz" and you're building a keymap for a rev5 planck, you'll use this command:
+
+    make planck/rev5:xyverz:dfu
+
+Once it finishes compiling, it should output the following:
+
+```
+Linking: .build/planck_rev5_xyverz.elf                                                              [OK]
+Creating load file for flashing: .build/planck_rev5_xyverz.hex                                      [OK]
+Copying planck_rev5_xyverz.hex to qmk_firmware folder                                               [OK]
+Checking file size of planck_rev5_xyverz.hex                                                        
+ * File size is fine - 18574/28672
+ ```
+
+After it gets to this point, the build script will look for the DFU bootloader every 5 seconds.  It will repeat the following until the device is found or you cancel it. 
+
+    dfu-programmer: no device present.
+    Error: Bootloader not found. Trying again in 5s.
+
+Once it does this, you'll want to reset the controller.  It should then show output similiar to this: 
+
+```
+*** Attempting to flash, please don't remove device
+>>> dfu-programmer atmega32u4 erase --force
+    Erasing flash...  Success
+    Checking memory from 0x0 to 0x6FFF...  Empty.
+>>> dfu-programmer atmega32u4 flash /Users/skully/qmk_firmware/clueboard_66_hotswap_gen1_skully.hex
+    Checking memory from 0x0 to 0x55FF...  Empty.

+    Validating...  Success
+    0x5600 bytes written into 0x7000 bytes memory (76.79%).
+>>> dfu-programmer atmega32u4 reset
+```
+
+If you have any issues with this, you may need to this: 
+
+    sudo make <my_keyboard>:<my_keymap>:dfu
+
+### Caterina 
+
+For Arduino boards and their close (such as the SparkFun ProMicro), when you're ready to compile and flash your firmware, open up your terminal window and run the built command: 
+
+    make <my_keyboard>:<my_keymap>:avrdude
+
+For example, if your keymap is named "xyverz" and you're building a keymap for a rev2 Lets Split, you'll use this command:
+
+    make lets_split/rev2:xyverz:avrdude
+
+Once the firmware finishes compiling, it will output something like this: 
+
+```
+Linking: .build/lets_split_rev2_xyverz.elf                                                            [OK]
+Creating load file for flashing: .build/lets_split_rev2_xyverz.hex                                    [OK]
+Checking file size of lets_split_rev2_xyverz.hex                                                      [OK]
+ * File size is fine - 27938/28672
+Detecting USB port, reset your controller now..............
+```
+
+At this point, reset the board and then the script will detect the bootloader and then flash the board.  The output should look something like this: 
+
+```
+Detected controller on USB port at /dev/ttyS15
+

+
+For example, if your keymap is named "xyverz" and you're building a keymap for an Ergodox or Ergodox EZ, you'll use this command:
+
+    make erdogox_ez:xyverz:teensy
+
+Once the firmware finishes compiling, it will output something like this: 
+
+```
+Linking: .build/ergodox_ez_xyverz.elf                                                               [OK]

+# Introduction
+
+Your computer keyboard has a processor inside of it, not unlike the one inside your computer. This processor runs software that is responsible for detecting button presses and sending reports about the state of the keyboard when they are pressed or released. QMK fills the role of that software, detecting button presses and passing that information on to the host computer. When you build your custom layout you are creating the equivalent of an .exe for your keyboard.
+
+QMK tries to put a lot of power into your hands by making easy things easy, and hard things possible. You don't have to know how to program to create powerful layouts, you only have to follow a few simple syntax rules.
+
+# Getting Started
+
+Before you can build keymaps you need to install some software and setup your build environment. This only has to be done one time no matter how many keyboards you want to compile firmware for.
+
+## Download Software
+
+### Text Editor
+
+You'll need a program that can edit and save **plain text** files. If you are on Windows you can make due with Notepad, and on Linux you can use Gedit, both of which are simple but functional text editors. On macOS be careful with TextEdit.app, it will not save plain text files unless you make sure to select "Make Plain text" from the "Format" menu, or you can use another program such as Sublime Text.
+
+?> Not sure which text editor to use? Laurence Bradford wrote [a great introduction](https://learntocodewith.me/programming/basics/text-editors/) to the subject.
+
+### QMK Toolbox
+
+QMK Toolbox is an optional graphical Windows and macOS program that allows you to both program and debug your custom keyboard. You will likely prefer it to easily flash your keyboard and receive the debugging messages that your keyboard will print.
+
+Download the files from the links below:
+
+For Windows: "qmk_toolbox.exe" or "qmk_toolbox_install.exe" (with installer)
+
+For Mac: "QMK.Toolbox.app.zip" or "QMK.Toolbox.pkg" (with installer)
+
+* [Newest Release](https://github.com/qmk/qmk_toolbox/releases/latest)
+* [Source Code](https://github.com/qmk/qmk_toolbox/)
+
+## Environment Setup
+
+We've tried to make QMK as easy to setup as possible. You only have to prepare your Linux or Unix environment and let QMK install the rest.
+
+?> If you haven't worked with the Linux/Unix command line before there are a few basic concepts and commands you should learn. These resources will teach you enough to work with QMK:<br>
+[Must Know Linux Commands](https://www.guru99.com/must-know-linux-commands.html)<br>
+[Some Basic Unix Commands](https://www.tjhsst.edu/~dhyatt/superap/unixcmd.html)
+
+### Windows
+
+You will need to install msys2 and git.
+
+* Follow the installation instructions on the msys2 homepage: http://www.msys2.org
+* Close any open msys2 terminals, and open a new terminal
+* Install git by running this command: `pacman -S git`
+
+### macOS
+
+You will need to install homebrew. Follow the instructions on the homebrew homepage: https://brew.sh
+
+After homebrew is installed continue with "Download QMK", following step "Setup QMK" runs a script that will install other packages.
+
+### Linux
+
+You will need to install git. It's extremely likely you already have it, but if not one of the following commands should install it:
+
+* Debian/Ubuntu/Devuan: `apt-get install git`
+* Fedora/Redhat/Centos: `yum install git`
+* Arch: `pacman -S git`
+
+## Download QMK
+
+Once you have setup your Linux/Unix environment you are ready to download QMK. We will do this by using git to "clone" the QMK repository. Open a Terminal or MSYS2 Console window and leave it open for the remainder of this guide. Inside that window run these two commands:
+
+    git clone https://github.com/qmk/qmk_firmware.git
+    cd qmk_firmware
+
+?> If you already know [how to use GitHub](getting_started_github.md) we recommend you create and clone your own fork instead. If you don't know what that means you can safely ignore this message.
+
+## Setup QMK
+
+QMK comes with a script to help you setup the rest of what you'll need. You should run it now by typing in this command:
+
+    ./util/qmk_install.sh
+
+## Test Your Build Environment
+
+Now that your QMK build environment is setup you can build a firmware for your keyboard. Start by trying to build the default layout for your keyboard. You should be able to do that with a command in this format:
+
+    make <keyboard>:default
+
+For example, to build a firmware for a Clueboard 66% use:
+
+    make clueboard/66/rev3:default
+
+When it is done you should have a lot of output that ends similar to this:
+
+```
+Linking: .build/clueboard_66_rev2_default.elf                                                       [OK]
+Creating load file for flashing: .build/clueboard_66_rev2_default.hex                               [OK]
+Copying clueboard_66_rev2_default.hex to qmk_firmware folder                                        [OK]
+Checking file size of clueboard_66_rev2_default.hex                                                 [OK]
+ * File size is fine - 25174/28672
+```
+
+## Creating Your Layout
+
+Now you are ready to create your own personal layout. Move on to [Building Your First Firmware](newbs_building_firmware.md) for that.

+# Testing and Debugging
+
+Once you've flashed your keyboard with a custom firmware you're ready to test it out. With a little bit of luck everything will work perfectly, but if not this document will help you figure out what's wrong.
+
+## Testing
+
+Testing your keyboard is usually pretty straightforward. Press every single key and make sure it sends the keys you expect. There are even programs that will help you make sure that no key is missed.
+
+Note: These programs are not provided by or endorsed by QMK.

+* [Keyboard Checker](http://keyboardchecker.com) (Web Based)
+
+## Debugging With QMK Toolbox
+
+[QMK Toolbox](https://github.com/qmk/qmk_toolbox) will show messages from your keyboard if you have `CONSOLE_ENABLE = yes` in your `rules.mk`. By default the output is very limited, but you can turn on debug mode to increase the amount of debug output. Use the `DEBUG` keycode in your keymap, or use the [Command](feature_command.md) feature to enable debug mode.
+

+## Sending Your Own Debug Messages
+
+Sometimes it's useful to print debug messages from within your [custom code](custom_quantum_functions.md). Doing so is pretty simple. Start by including `print.h` at the top of your file:
+
+    #include <print.h>
+
+After that you can use a few different print functions:
+
+* `print("string")`: Print a simple string.
+* `sprintf("%s string", var)`: Print a formatted string
+* `dprint("string")` Print a simple string, but only when debug mode is enabled
+* `dprintf("%s string", var)`: Print a formatted string, but only when debug mode is enabled

+# List of Useful Core Functions To Make Your Keyboard Better
+
+There are a lot of hidden functions in QMK that are incredible useful, or may add a bit of functionality that you've been wanting.  Functions that are specific to certain features are not included here, as those will be on their respective feature page. 
+
+## (OLKB) Tri Layers
+
+There are actually separate functions that you can use there, depending on what you're after. 
+
+The first is the `update_tri_layer(x, y, z)` function.   This function check to see if layers `x` and `y` are both on. If they are both on, then it runs on layer `z`.  Otherwise, if both `x` and `y` are not both on (either only one is, or neither is), then it runs off layer `z`. 
+
+This function is useful if you want to create specific keys that have this functionality, but other layer keycodes won't do this. 
+
+The other function is `update_tri_layer_state(state, x, y, z)`.  This function is meant to be called from they [`layer_state_set_*` functions](custom_quantum_functions.md#layer-change-code).  This means that any time that you use a keycode to change the layer, this will be checked.  So you could use `LT(layer, kc)` to change the layer and it will trigger the same layer check. 
+
+The caveat to this method is that you cannot access the `z` layer without having `x` and `y` layers on, since if you try to activate just layer `z`, it will run this code and turn off layer `z` before you could use it. 
+
+## Setting the Persistent Default Layer
+
+Do you want to set the default layer, so that it's retained even after you unplug the board?  If so, this is the function for you. 
+
+To use this, you would use `set_single_persistent_default_layer(layer)`.  If you have a name defined for your layer, you can use that instead (such as _QWERTY, _DVORAK or _COLEMAK). 
+
+This will set the default layer, update the persistent settings, and play a tune if you have [Audio](feature_audio.md) enabled on your board, and the default layer sounds set. 
+
+To configure the default layer sounds, you would want to define this in your `config.h` file, like this: 
+
+```c
+#define DEFAULT_LAYER_SONGS { SONG(QWERTY_SOUND), \
+                              SONG(COLEMAK_SOUND), \
+                              SONG(DVORAK_SOUND) \
+                            }
+```
+
+
+?> There are a large number of predefined songs in [quantum/audio/song_list.h](https://github.com/qmk/qmk_firmware/blob/master/quantum/audio/song_list.h) that you can use.
+
+## Reseting the keyboard
+
+There is the `RESET` quantum keycode that you can use. But if you want to reset the board as part of a macro, rather than hitting a key separately, you can do that. 
+
+And to do so, add `reset_keyboard()` to your function or macro, and this will reset to bootloader.
+
+## Wiping the EEPROM (Persistent Storage)
+
+If you're having issues with Audio, RGB Underglow, backlighting or keys acting weird, then you can reset the EEPROM (persistent setting storage).  Bootmagic is one way to do this, but if that isn't enabled, then you can use a custom macro to do so. 
+
+To wipe the EEPROM, run `eeconfig_init()` from your function or macro to reset most of the settings to default.

However, if you look at a 17 key numpad you'll notice that it has 3 places where the matrix could have a switch but doesn't, due to larger keys.

+ Title:     HD44780U LCD library
+ Author:    Peter Fleury <pfleury@gmx.ch>  http://tinyurl.com/peterfleury
+ License:   GNU General Public License Version 3
+ File:	    $Id: lcd.c,v 1.15.2.2 2015/01/17 12:16:05 peter Exp $
+ Software:  AVR-GCC 3.3 
+ Target:    any AVR device, memory mapped mode only for AT90S4414/8515/Mega
+
+ DESCRIPTION
+       Basic routines for interfacing a HD44780U-based text lcd display
+
+       Originally based on Volker Oth's lcd library,
+       changed lcd_init(), added additional constants for lcd_command(),
+       added 4-bit I/O mode, improved and optimized code.
+
+       Library can be operated in memory mapped mode (LCD_IO_MODE=0) or in 
+       4-bit IO port mode (LCD_IO_MODE=1). 8-bit IO port mode not supported.
+       
+       Memory mapped mode compatible with Kanda STK200, but supports also
+       generation of R/W signal through A8 address line.
+
+ USAGE
+       See the C include lcd.h file for a description of each function

+ @brief Basic routines for interfacing a HD44780U-based character LCD display
+
+ 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 
+ 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.
+
+ @see The chapter <a href=" http://homepage.hispeed.ch/peterfleury/avr-lcd44780.html" target="_blank">Interfacing a HD44780 Based LCD to an AVR</a>
+      on my home page, which shows example circuits how to connect an LCD to an AVR controller.
