+# QMK Breaking Changes - 2022 August 27 Changelog
+
+## Notable Features :id=notable-features
+
+### Add Raspberry Pi RP2040 support ([#14877](https://github.com/qmk/qmk_firmware/pull/14877), [#17514](https://github.com/qmk/qmk_firmware/pull/17514), [#17516](https://github.com/qmk/qmk_firmware/pull/17516), [#17519](https://github.com/qmk/qmk_firmware/pull/17519), [#17612](https://github.com/qmk/qmk_firmware/pull/17612), [#17512](https://github.com/qmk/qmk_firmware/pull/17512), [#17557](https://github.com/qmk/qmk_firmware/pull/17557), [#17817](https://github.com/qmk/qmk_firmware/pull/17817), [#17839](https://github.com/qmk/qmk_firmware/pull/17839), [#18100](https://github.com/qmk/qmk_firmware/pull/18100)) :id=rp2040-support
+
+QMK _finally_ picked up support for RP2040-based boards, such as the Raspberry Pi Pico, the Sparkfun Pro Micro RP2040, and the Adafruit KB2040. One of QMK's newest collaborators, _@KarlK90_, effectively did `/micdrop` with RP2040, with a massive set of changes to both QMK and the repository QMK uses for the base platform support, ChibiOS[-Contrib]. There has been a flurry of development this breaking changes cycle related to RP2040 from a large number of contributors -- so much so that almost all standard QMK hardware subsystems are supported.
+
+Check the [RP2040 platform development page](platformdev_rp2040.md) for all supported peripherals and other hardware implementation details.
+
+### Allow `qmk flash` to use prebuilt firmware binaries ([#16584](https://github.com/qmk/qmk_firmware/pull/16584)) :id=cli-flash-binaries
+
+A long-requested capability of the QMK CLI has been the ability to flash binaries directly, without needing to build a firmware. QMK provides prebuilt `develop`-based default firmwares on our [CI page](https://qmk.tzarc.io/) -- normally people would need [QMK Toolbox](https://github.com/qmk/qmk_toolbox/releases/latest) to flash them. This new functionality written by _@Erovia_ allows `qmk flash` to be provided the prebuilt file instead, simplifying the workflow for people who haven't got Toolbox available.
+
+## Changes Requiring User Action :id=changes-requiring-user-action
+
+### Default layers dropped from 32 to 16 ([#15286](https://github.com/qmk/qmk_firmware/pull/15286))
+
+QMK allows for controlling the maximum number of layers it supports through `LAYER_STATE_(8|16|32)BIT`. Each definition allows for the same number of maximum layers -- `LAYER_STATE_8BIT` => 8 layers. There is also a corresponding firmware size decrease that goes along with smaller numbers -- given the vast majority of users don't use more than 16 layers the default has been swapped to 16. AVR users who were not previously specifying their max layer count may see some space freed up as a result.
+
+### `RESET` => `QK_BOOT` ([#17940](https://github.com/qmk/qmk_firmware/pull/17940)) :id=reset-2-qk_boot
+
+Following the last breaking changes cycle, QMK has been migrating usages of `RESET` to `QK_BOOT` due to naming collisions with our upstream board support packages. [#17940](https://github.com/qmk/qmk_firmware/pull/17940) converts user keymaps across to use the new keycode name. `RESET` should also move to `QK_BOOT`.
+
+### Updated Keyboard Codebases :id=updated-keyboard-codebases
+
+The following keyboards have had their source moved within QMK:
+
+| Old Keyboard Name      | New Keyboard Name        |
+|------------------------|--------------------------|
+| gentleman65            | jkeys_design/gentleman65 |
+| handwired/hillside/0_1 | handwired/hillside/48    |
+| idobao/id80/v1/ansi    | idobao/id80/v2/ansi      |
+| idobao/id80/v1/iso     | idobao/id80/v2/iso       |
+
+### Data-driven USB IDs Refactoring ([#18152](https://github.com/qmk/qmk_firmware/pull/18152)) :id=usb-ids-Refactoring
+
+QMK has decided to deprecate the specification of USB IDs inside `config.h` in favour of `info.json`, eventually leaving data-driven as the only method to specify USB information.
+
+A significant number of keyboards have already been changed on `master` in a like-for-like fashion, and [#18152](https://github.com/qmk/qmk_firmware/pull/18152) performs the same transformations for keyboards already on `develop`.
+
+Previously in `config.h`:
+```c
+#define VENDOR_ID    0x1234
+#define PRODUCT_ID   0x5678
+#define DEVICE_VER   0x0001
+#define MANUFACTURER Me
+#define PRODUCT      MyKeyboard
+```
+
+Replaced by `info.json`:
+```json
+{
+    "keyboard_name": "MyKeyboard",
+    "manufacturer": "Me",
+    "usb": {
+        "vid": "0x1234",
+        "pid": "0x5678",
+        "device_version": "0.0.1"
+    },
+    // ... layouts, etc. ...
+}
+```
+
+#### Deprecation Schedule
+
+- From 2022 Aug 27, specifying USB information in `config.h` will produce warnings during build but will still function as previously.
+- From 2022 Nov 26, specifying USB information in `config.h` will cause compilation to fail.
+
+## Notable core changes :id=notable-core
+
+### Board converters ([#17514](https://github.com/qmk/qmk_firmware/pull/17514), [#17603](https://github.com/qmk/qmk_firmware/pull/17603), [#17711](https://github.com/qmk/qmk_firmware/pull/17711), [#17827](https://github.com/qmk/qmk_firmware/pull/17827), [#17593](https://github.com/qmk/qmk_firmware/pull/17593), [#17652](https://github.com/qmk/qmk_firmware/pull/17652), [#17595](https://github.com/qmk/qmk_firmware/pull/17595)) :id=board-converters
+
+Historically QMK had a `CONVERT_TO_PROTON_C` directive for `rules.mk` to allow people to replace an AVR-based Pro Micro with a QMK Proton C. Global parts shortages have prompted people to create their own pin-compatible boards -- QMK has made this conversion generic and now allows for drop-in replacements for a lot more boards. see the [Converters Feature](feature_converters.md) documentation for the full list of supported replacement boards -- in this breaking changes cycle we've gone from 1 to 7.
+
+### Add cli command to import keyboard|keymap|kbfirmware ([#16668](https://github.com/qmk/qmk_firmware/pull/16668)) :id=cli-import
+
+To help with importing keyboards and keymaps from other sources, _@zvecr_ added [#16668](https://github.com/qmk/qmk_firmware/pull/16668) which adds a new set of commands to the CLI to automatically import keyboards (`qmk import-keyboard -h`), keymaps (`qmk import-keymap -h`), and kbfirmware definitions (`qmk import-kbfirmware -h`) into QMK.
+
+The now-EOL kbfirmware allowed people who aren't set up with QMK the ability to create keyboard firmwares without requiring a full installation of QMK. Unfortunately, it targets a 7-year-old version of QMK -- adding frustration for users who want the newest features, as well as for QMK maintainers who have to spend time explaining why QMK can't just accept a drive-by code drop from kbfirmware. With any luck, this new command helps both camps!
+
+### Generic wear-leveling for EEPROM emulation ([#16996](https://github.com/qmk/qmk_firmware/pull/16996), [#17376](https://github.com/qmk/qmk_firmware/pull/17376), [#18102](https://github.com/qmk/qmk_firmware/pull/18102)) :id=wear-leveling
+
+QMK has had the ability to write to internal MCU flash in order to emulate EEPROM for some time now, but it was only limited to a small number of MCUs. The base HAL used by QMK for a large number of ARM devices provides a "proper" embedded MCU flash driver, so _@tzarc_ decoupled the wear-leveling algorithm from the old flash writing code, improved it, wrote some tests, and enabled its use for a much larger number of other devices... including RP2040's XIP flash, and external SPI NOR Flash.
+
+See the [EEPROM Driver](eeprom_driver.md) documentation for more information.
+
+### Pointing Device Improvements ([#16371](https://github.com/qmk/qmk_firmware/pull/16371), [#17111](https://github.com/qmk/qmk_firmware/pull/17111), [#17176](https://github.com/qmk/qmk_firmware/pull/17176), [#17482](https://github.com/qmk/qmk_firmware/pull/17482), [#17776](https://github.com/qmk/qmk_firmware/pull/17776), [#17613](https://github.com/qmk/qmk_firmware/pull/17613)) :id=pointing-device-improvements
+
+Ever since Pointing Device Driver support and Split Pointing Device support were added by _@drashna_ and _@daskygit_, there has been increased interest in the development of the pointing device subsystem and its associated code.
+
+Both the PMW33xx and the Cirque Pinnacle implementations have seen a lot of improvement to their code, as has the mouse code in general. Features like circular/edge scrolling for the Cirque, and Kinetic movement for any sensor with "lift detection" ([#17482](https://github.com/qmk/qmk_firmware/pull/17482)). Additionally, for those that make fast motions with their pointing devices, support for much larger mouse movement reports has been added ([#16371](https://github.com/qmk/qmk_firmware/pull/16371)).
+
+Other related changes:
+
+* Add support for large Mouse Reports ([#16371](https://github.com/qmk/qmk_firmware/pull/16371))
+* Improve PS/2 mouse performance ([#17111](https://github.com/qmk/qmk_firmware/pull/17111))
+* Mouse key kinetic mode fix ([#17176](https://github.com/qmk/qmk_firmware/pull/17176))
+* Circular scroll, inertial cursor ([#17482](https://github.com/qmk/qmk_firmware/pull/17482))
+* Create generic Pointing Device Pin defines ([#17776](https://github.com/qmk/qmk_firmware/pull/17776))
+* PMW33XX drivers overhaul ([#17613](https://github.com/qmk/qmk_firmware/pull/17613))

+`WEAR_LEVELING_DRIVER = embedded_flash` | This driver is used for emulating EEPROM by writing to embedded flash on the MCU.
+`WEAR_LEVELING_DRIVER = spi_flash`      | This driver is used to address external SPI NOR Flash peripherals.
+`WEAR_LEVELING_DRIVER = rp2040_flash`   | This driver is used to write to the same storage the RP2040 executes code from.
+`WEAR_LEVELING_DRIVER = legacy`         | This driver is the "legacy" emulated EEPROM provided in historical revisions of QMK. Currently used for STM32F0xx and STM32F4x1, but slated for deprecation and removal once `embedded_flash` support for those MCU families is complete.
+
+!> All wear-leveling drivers require an amount of RAM equivalent to the selected logical EEPROM size. Increasing the size to 32kB of EEPROM requires 32kB of RAM, which a significant number of MCUs simply do not have.
+
+## Wear-leveling Embedded Flash Driver Configuration :id=wear_leveling-efl-driver-configuration
+
+This driver performs writes to the embedded flash storage embedded in the MCU. In most circumstances, the last few of sectors of flash are used in order to minimise the likelihood of collision with program code.
+
+Configurable options in your keyboard's `config.h`:
+
+`config.h` override                      | Default     | Description
+-----------------------------------------|-------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
+`#define WEAR_LEVELING_EFL_FIRST_SECTOR` | _unset_     | The first sector on the MCU to use. By default this is not defined and calculated at runtime based on the MCU. However, different flash sizes on MCUs may require custom configuration.
+`#define WEAR_LEVELING_EFL_FLASH_SIZE`   | _unset_     | Allows overriding the flash size available for use for wear-leveling. Under normal circumstances this is automatically calculated and should not need to be overridden. Specifying a size larger than the amount actually available in flash will usually prevent the MCU from booting.
+`#define WEAR_LEVELING_LOGICAL_SIZE`     | `1024`      | Number of bytes "exposed" to the rest of QMK and denotes the size of the usable EEPROM.
+`#define WEAR_LEVELING_BACKING_SIZE`     | `2048`      | Number of bytes used by the wear-leveling algorithm for its underlying storage, and needs to be a multiple of the logical size.
+`#define BACKING_STORE_WRITE_SIZE`       | _automatic_ | The byte width of the underlying write used on the MCU, and is usually automatically determined from the selected MCU family. If an error occurs in the auto-detection, you'll need to consult the MCU's datasheet and determine this value, specifying it directly.
+
+!> If your MCU does not boot after swapping to the EFL wear-leveling driver, it's likely that the flash size is incorrectly detected, usually as an MCU with larger flash and may require overriding.
+
+## Wear-leveling SPI Flash Driver Configuration :id=wear_leveling-flash_spi-driver-configuration
+
+This driver performs writes to an external SPI NOR Flash peripheral. It also requires a working configuration for the SPI NOR Flash peripheral -- see the [flash driver](flash_driver.md) documentation for more information.
+
+Configurable options in your keyboard's `config.h`:
+
+`config.h` override                                 | Default                        | Description
+----------------------------------------------------|--------------------------------|--------------------------------------------------------------------------------------------------------------------------------
+`#define WEAR_LEVELING_EXTERNAL_FLASH_BLOCK_COUNT`  | `1`                            | Number of blocks in the external flash used by the wear-leveling algorithm.
+`#define WEAR_LEVELING_EXTERNAL_FLASH_BLOCK_OFFSET` | `0`                            | The index first block in the external flash used by the wear-leveling algorithm.
+`#define WEAR_LEVELING_LOGICAL_SIZE`                | `((block_count*block_size)/2)` | Number of bytes "exposed" to the rest of QMK and denotes the size of the usable EEPROM. Result must be <= 64kB.
+`#define WEAR_LEVELING_BACKING_SIZE`                | `(block_count*block_size)`     | Number of bytes used by the wear-leveling algorithm for its underlying storage, and needs to be a multiple of the logical size.
+`#define BACKING_STORE_WRITE_SIZE`                  | `8`                            | The write width used whenever a write is performed on the external flash peripheral.
+
+!> There is currently a limit of 64kB for the EEPROM subsystem within QMK, so using a larger flash is not going to be beneficial as the logical size cannot be increased beyond 65536. The backing size may be increased to a larger value, but erase timing may suffer as a result.
+
+## Wear-leveling RP2040 Driver Configuration :id=wear_leveling-rp2040-driver-configuration
+
+This driver performs writes to the same underlying storage that the RP2040 executes its code.
+
+Configurable options in your keyboard's `config.h`:
+
+`config.h` override                       | Default                    | Description
+------------------------------------------|----------------------------|--------------------------------------------------------------------------------------------------------------------------------
+`#define WEAR_LEVELING_RP2040_FLASH_SIZE` | `PICO_FLASH_SIZE_BYTES`    | Number of bytes of flash on the board.
+`#define WEAR_LEVELING_RP2040_FLASH_BASE` | `(flash_size-sector_size)` | The byte-wise location that the backing storage should be located.
+`#define WEAR_LEVELING_LOGICAL_SIZE`      | `4096`                     | Number of bytes "exposed" to the rest of QMK and denotes the size of the usable EEPROM.
+`#define WEAR_LEVELING_BACKING_SIZE`      | `8192`                     | Number of bytes used by the wear-leveling algorithm for its underlying storage, and needs to be a multiple of the logical size as well as the sector size.
+`#define BACKING_STORE_WRITE_SIZE`        | `2`                        | The write width used whenever a write is performed on the external flash peripheral.
+
+## Wear-leveling Legacy EEPROM Emulation Driver Configuration :id=wear_leveling-legacy-driver-configuration
+
+This driver performs writes to the embedded flash storage embedded in the MCU much like the normal Embedded Flash Driver, and is only for use with STM32F0xx and STM32F4x1 devices. This flash implementation is still currently provided as the EFL driver is currently non-functional for the previously mentioned families.
+
+By default, `1024` bytes of emulated EEPROM is provided:
+
+MCU       | EEPROM Provided | Flash Used
+----------|-----------------|--------------
+STM32F042 | `1024` bytes    | `2048` bytes
+STM32F070 | `1024` bytes    | `2048` bytes
+STM32F072 | `1024` bytes    | `2048` bytes
+STM32F401 | `1024` bytes    | `16384` bytes
+STM32F411 | `1024` bytes    | `16384` bytes
+
+Under normal circumstances configuration of this driver requires intimate knowledge of the MCU's flash structure -- reconfiguration is at your own risk and will require referring to the code.

+# Converters
+
+Since many drop-in replacement controllers now exist, we've done our best to make them easy to use in existing designs.
+
+This page documents the handy automated process for converting keyboards.
+
+### Supported Converters
+
+Currently the following converters are available:
+
+| From       | To                |
+|------------|-------------------|
+| `promicro` | `proton_c`        |
+| `promicro` | `kb2040`          |
+| `promicro` | `promicro_rp2040` |
+| `promicro` | `blok`            |
+| `promicro` | `bit_c_pro`       |
+| `promicro` | `stemcell`        |
+| `promicro` | `bonsai_c4`       |
+
+See below for more in depth information on each converter.
+
+## Overview
+
+Each converter category is broken down by its declared `pin compatibility`.
+This ensures that only valid combinations are attempted.
+
+You can generate the firmware by appending `-e CONVERT_TO=<target>` to your compile/flash command. For example:
+
+```sh
+qmk flash -c -kb keebio/bdn9/rev1 -km default -e CONVERT_TO=proton_c
+```
+
+You can also add the same `CONVERT_TO=<target>` to your keymap's `rules.mk`, which will accomplish the same thing.
+
+?> If you get errors about `PORTB/DDRB`, etc not being defined, you'll need to convert the keyboard's code to use the [GPIO Controls](gpio_control.md) that will work for both ARM and AVR. This shouldn't affect the AVR builds at all.
+
+### Conditional Configuration
+
+Once a converter is enabled, it exposes the `CONVERT_TO_<target_uppercase>` flag that you can use in your code with `#ifdef`s, For example:
+
+```c
+#ifdef CONVERT_TO_PROTON_C
+    // Proton C code
+#else
+    // Pro Micro code
+#endif
+```
+
+## Pro Micro

+
+Feature set currently identical to [Proton C](#proton_c).
+There are two versions of STeMCell available, with different pinouts:
+  - v1.0.0
+  - v2.0.0 (pre-release v1.0.1, v1.0.2)
+Default official firmware only supports v2.0.0 STeMCell.
+
+STeMCell has support to swap UART and I2C pins, to enable single-wire uart communication in STM chips.
+
+The following additional flags has to be used while compiling, based on the pin used for split communication.
+
+| Split Pin | Compile flags |
+|-----------|---------------|
+| D3        | -e STMC_US=yes|
+| D2        | Not needed    |
+| D1        | -e STMC_IS=yes|
+| D0        | Not needed    |
+
+### Bonsai C4 :id=bonsai_c4
+
+The Bonsai C4 only has one on-board LED (B2), and by default, both the Pro Micro TXLED (D5) and RXLED (B0) are mapped to it. If you want only one of them mapped, you can undefine one and redefine it to another pin by adding these line to your `config.h`:
+
+```c
+#undef B0
+// If Vbus detection is unused, we can send RXLED to the Vbus detect pin instead
+#define B0 PAL_LINE(GPIOA, 9)
+```
+
+No peripherals are enabled by default at this time, but example code to enable SPI, I2C, PWM, and Serial communications can be found [here](/keyboards/custommk/bonsai_c4_template)

 Tips:
 
 * The smoothness of the cursor movement depends on the `MOUSEKEY_INTERVAL` setting. The shorter the interval is set the smoother the movement will be.  Setting the value too low makes the cursor unresponsive.  Lower settings are possible if the micro processor is fast enough. For example: At an interval of `8` milliseconds, `125` movements per second will be initiated.  With a base speed of `1000` each movement will move the cursor by `8` pixels.
-* Mouse wheel movements are implemented differently from cursor movements. While it's okay for the cursor to move multiple pixels at once for the mouse wheel this would lead to jerky movements. Instead, the mouse wheel operates at step size `1`. Setting mouse wheel speed is done by adjusting the number of wheel movements per second.

 !> When using `SPLIT_POINTING_ENABLE` the `POINTING_DEVICE_MOTION_PIN` functionality is not supported and `POINTING_DEVICE_TASK_THROTTLE_MS` will default to `1`. Increasing this value will increase transport performance at the cost of possible mouse responsiveness.
 
+The `POINTING_DEVICE_CS_PIN`, `POINTING_DEVICE_SDIO_PIN`, and `POINTING_DEVICE_SCLK_PIN` provide a convenient way to define a single pin that can be used for an interchangeable sensor config.  This allows you to have a single config, without defining each device.  Each sensor allows for this to be overridden with their own defines. 
+
+!> Any pointing device with a lift/contact status can integrate inertial cursor feature into its driver, controlled by `POINTING_DEVICE_GESTURES_CURSOR_GLIDE_ENABLE`. e.g. PMW3360 can use Lift_Stat from Motion register. Note that `POINTING_DEVICE_MOTION_PIN` cannot be used with this feature; continuous polling of `get_report()` is needed to generate glide reports.
 
 ## Split Keyboard Configuration
 
 The following configuration options are only available when using `SPLIT_POINTING_ENABLE` see [data sync options](feature_split_keyboard.md?id=data-sync-options). The rotation and invert `*_RIGHT` options are only used with `POINTING_DEVICE_COMBINED`. If using `POINTING_DEVICE_LEFT` or `POINTING_DEVICE_RIGHT` use the common configuration above to configure your pointing device.

+# Secure
+
+The secure feature aims to prevent unwanted interaction without user intervention.
+
+?> Secure does **not** currently implement encryption/decryption/etc and should not be a replacement where a strong hardware/software based solution is required.
+
+### Unlock sequence
+
+To unlock, the user must perform a set of actions. This can optionally be configured to be multiple keys.
+
+* While unlocking all keyboard input is ignored
+* Incorrect attempts will revert back to the previously locked state
+
+### Automatic Locking
+

+# Send String
+
+The Send String API is part of QMK's macro system. It allows for sequences of keystrokes to be sent automatically.
+
+The full ASCII character set is supported, along with all of the keycodes in the Basic Keycode range (as these are the only ones that will actually be sent to the host).
+
+?> Unicode characters are **not** supported with this API -- see the [Unicode](feature_unicode.md) feature instead.
+
+## Usage
+
+Send String is enabled by default, so there is usually no need for any special setup. However, if it is disabled, add the following to your `rules.mk`:
+
+```make
+SEND_STRING_ENABLE = yes
+```
+
+## Basic Configuration
+
+Add the following to your `config.h`:
+
+|Define           |Default         |Description                                                                                                 |

+
+## Keycodes
+
+The Send String functions accept C string literals, but specific keycodes can be injected with the below macros. All of the keycodes in the [Basic Keycode range](keycodes_basic.md) are supported (as these are the only ones that will actually be sent to the host), but with an `X_` prefix instead of `KC_`.
+
+|Macro         |Description                                                        |

+|`SS_TAP(x)`   |Send a keydown, then keyup, event for the given Send String keycode|
+|`SS_DOWN(x)`  |Send a keydown event for the given Send String keycode             |
+|`SS_UP(x)`    |Send a keyup event for the given Send String keycode               |
+|`SS_DELAY(ms)`|Wait for `ms` milliseconds                                         |
+
+The following characters are also mapped to their respective keycodes for convenience:
+
+|Character|Hex   |ASCII|Keycode       |
+|---------|------|-----|--------------|
+|`\b`     |`\x08`|`BS` |`KC_BACKSPACE`|
+|`\e`     |`\x09`|`ESC`|`KC_ESCAPE`   |
+|`\n`     |`\x0A`|`LF` |`KC_ENTER`    |
+|`\t`     |`\x1B`|`TAB`|`KC_TAB`      |
+|         |`\x7F`|`DEL`|`KC_DELETE`   |
+
+### Language Support
+
+By default, Send String assumes your OS keyboard layout is set to US ANSI. If you are using a different keyboard layout, you can [override the lookup tables used to convert ASCII characters to keystrokes](reference_keymap_extras.md#sendstring-support).
+
+## Examples
+
+### Hello World
+
+A simple custom keycode which types out "Hello, world!" and the Enter key when pressed.
+
+Add the following to your `keymap.c`:
+
+```c
+bool process_record_user(uint16_t keycode, keyrecord_t *record) {
+    switch (keycode) {
+        case SS_HELLO:
+            if (record->event.pressed) {
+                SEND_STRING("Hello, world!\n");
+            }
+            return false;
+    }
+
+    return true;
+}
+```
+
+### Keycode Injection
+
+This example types out opening and closing curly braces, then taps the left arrow key to move the cursor between the two.
+
+```c
+SEND_STRING("{}" SS_TAP(X_LEFT));
+```
+
+This example types Ctrl+A, then Ctrl+C, without releasing Ctrl.
+
+```c
+SEND_STRING(SS_LCTL("ac"));

-TX Bolt communicates the status of 24 keys over a very simple protocol in variable-sized (1-5 byte) packets.
+TX Bolt communicates the status of 24 keys over a simple protocol in variable-sized (1–4 bytes) packets.
+
+To select TX Bolt, add the following lines to your `rules.mk`:
+```mk
+STENO_ENABLE = yes
+STENO_PROTOCOL = txbolt
+```
+
+Each byte of the packet represents a different group of steno keys. Determining the group of a certain byte of the packet is done by checking the first two bits, the remaining bits are set if the corresponding steno key was pressed for the stroke. The last set of keys (as indicated by leading `11`) needs to keep track of less keys than there are bits so one of the bits is constantly 0.
+
+The start of a new packet can be detected by comparing the group “ID” (the two MSBs) of the current byte to that of the previously received byte. If the group “ID” of the current byte is smaller or equal to that of the previous byte, it means that the current byte is the beginning of a new packet.
+
+The format of TX Bolt packets is shown below.
+```
+00HWPKTS 01UE*OAR 10GLBPRF 110#ZDST
+```
+
+Examples of steno strokes and the associated packet:

+### Switching protocols on the fly :id=switching-protocols-on-the-fly
+
+If you wish to switch the serial protocol used to transfer the steno chords without having to recompile your keyboard firmware every time, you can press the `QK_STENO_BOLT` and `QK_STENO_GEMINI` keycodes in order to switch protocols on the fly.
+
+To enable these special keycodes, add the following lines to your `rules.mk`:
+```mk
+STENO_ENABLE = yes
+STENO_PROTOCOL = all
+```
+
+If you want to switch protocols programatically, as part of a custom macro for example, don't use `tap_code(QK_STENO_*)`, as `tap_code` only supports [basic keycodes](keycodes_basic). Instead, you should use `steno_set_mode(STENO_MODE_*)`, whose valid arguments are `STENO_MODE_BOLT` and `STENO_MODE_GEMINI`.
+
+The default protocol is Gemini PR but the last protocol used is stored in non-volatile memory so QMK will remember your choice between reboots of your keyboard — assuming that your keyboard features (emulated) EEPROM.
+
+Naturally, this option takes the most amount of firmware space as it needs to compile the code for all the available stenography protocols. In most cases, compiling a single stenography protocol is sufficient.
+
+The default value for `STENO_PROTOCOL` is `all`.

+Next, you will want to define some tap-dance keys, which is easiest to do with the `TD()` macro. That macro takes a number which will later be used as an index into the `tap_dance_actions` array and turns it into a tap-dance keycode.
 
 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_LAYER_MOVE(kc, layer)`: Sends the `kc` keycode when tapped once, or moves to `layer`. (this functions like the `TO` layer keycode).
-    * This is the same as `ACTION_TAP_DANCE_DUAL_ROLE`, but renamed to something that is clearer about its functionality.  Both names will work.
 * `ACTION_TAP_DANCE_LAYER_TOGGLE(kc, layer)`: Sends the `kc` keycode when tapped once, or toggles the state of `layer`. (this functions like the `TG` 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 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`.
-    * This is deprecated in favor of the Per Key Tapping Term functionality, as outlined [here](tap_hold.md#tapping-term). You'd want to check for the specific `TD()` macro that you want to use (such as `TD(TD_ESC_CAPS)`) instead of using this specific Tap Dance function.
 
 
 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. 
 
 !> Keep in mind that only [basic keycodes](keycodes_basic.md) are supported here. Custom keycodes are not supported.

+Similar to the first option, the second and third option are good for simple layer-switching cases.

-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.

 ## Implementation Details :id=implementation
 
 Well, that's the bulk of it! You should now be able to work through the examples below, and to develop your own Tap Dance functionality. But if you want a deeper understanding of what's going on behind the scenes, then read on for the explanation of how it all works!
 
-The main entry point is `process_tap_dance()`, called from `process_record_quantum()`, which is run for every keypress, and our handler gets to run early. 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 reset the timer.
+Let's go over the three functions mentioned in `ACTION_TAP_DANCE_FN_ADVANCED` in a little more detail. They all receive the same too arguments: a pointer to a structure that holds all dance related state information, and a pointer to a use case specific state variable. The three functions differ in when they are called. The first, `on_each_tap_fn()`, is called every time the tap dance key is *pressed*. Before it is called, the counter is incremented and the timer is reset. The second function, `on_dance_finished_fn()`, is called when the tap dance is interrupted or ends because `TAPPING_TERM` milliseconds have passed since the last tap. When the `finished` field of the dance state structure is set to `true`, the `on_dance_finished_fn()` is skipped. After `on_dance_finished_fn()` was called or would have been called, but no sooner than when the tap dance key is *released*, `on_dance_reset_fn()` is called. It is possible to end a tap dance immediately, skipping `on_dance_finished_fn()`, but not `on_dance_reset_fn`, by calling `reset_tap_dance(state)`.
+
+To accomplish this logic, the tap dance mechanics use three entry points. The main entry point is `process_tap_dance()`, called from `process_record_quantum()` *after* `process_record_kb()` and `process_record_user()`. This function is responsible for calling `on_each_tap_fn()` and `on_dance_reset_fn()`. In order to handle interruptions of a tap dance, another entry point, `preprocess_tap_dance()` is run right at the beginning of `process_record_quantum()`. 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. Finally, `tap_dance_task()` periodically checks whether `TAPPING_TERM` has passed since the last key press and finishes a tap dance if that is the case.
 
 This means that you have `TAPPING_TERM` time to tap the key again; you do not have to input all the taps within a single `TAPPING_TERM` timeframe. This allows for longer tap counts, with minimal impact on responsiveness.
 
-Our next stop is `tap_dance_task()`. This handles the timeout of tap-dance keys.
-
-For the sake of flexibility, tap-dance actions can be either a pair of keycodes, or a user function. The latter allows one to handle higher tap counts, or do extra things, like blink the LEDs, fiddle with the backlighting, and so on. This is accomplished by using an union, and some clever macros.

-The terminal feature is a command-line-like interface designed to communicate through a text editor with keystrokes. It's beneficial to turn off auto-indent features in your editor.
-
-To enable, stick this in your `rules.mk` or `Makefile`:

-
-And use the `TERM_ON` and `TERM_OFF` keycodes to turn it on or off.
-
-When enabled, a `> ` prompt will appear, where you'll be able to type, backspace (a bell will ding if you reach the beginning and audio is enabled), and hit enter to send the command. Arrow keys are currently disabled so it doesn't get confused. Moving your cursor around with the mouse is discouraged.

+# Building QMK with GitHub Userspace
+
+This is an intermediate QMK tutorial to setup an out-of-tree build environment with a personal GitHub repository. It avoids using a fork of the QMK firmware to store and build your keymap within its source tree. Keymap files will instead be stored in your own personal GitHub repository, in [Userspace](https://docs.qmk.fm/#/feature_userspace) format, and built with an action workflow. Unlike the [default tutorial](https://docs.qmk.fm/#/newbs), this guide requires some familiarity with using Git.
+
+?> **Is This Guide For Me?**<br>
+This is a lean setup to avoid space-consuming local build environment in your computer. Troubleshooting compile-time errors will be slower with commit uploads to GitHub for the compiler workflow.
+
+
+## Prerequisites
+
+The following are required to get started:
+
+* [GitHub Account](https://github.com/new)
+  * A working account is required to setup and host your repository for GitHub Actions to build QMK firmware.
+* [Text editor](newbs_learn_more_resources.md#text-editor-resources)
+  * You’ll need a program that can edit and save plain text files. The default editor that comes with many OS's does not save plain text files, so you'll need to make sure that whatever editor you chose does.
+* [Toolbox](https://github.com/qmk/qmk_toolbox)
+  * A graphical program for Windows and macOS that allows you to both program and debug your custom keyboard.
+
+
+## Environment Setup
+
+?> If you are familiar with using [github.dev](https://docs.github.com/en/codespaces/the-githubdev-web-based-editor), you can skip to [step 2](#_2-create-github-repository) and commit the code files that follows directly on GitHub using the web-based VSCode editor.
+
+### 1. Install Git
+
+A working Git client is required for your local operating system to commit and push changes to GitHub.
+
+<!-- tabs:start -->
+
+### ** Windows **
+
+QMK maintains a bundle of MSYS2, the CLI and all necessary dependencies including Git. Install [QMK MSYS](https://msys.qmk.fm/) with the latest release [here](https://github.com/qmk/qmk_distro_msys/releases/latest). Git will be part of the bundle.
+
+### ** macOS **
+
+Install Homebrew following the instructions on https://brew.sh. Git will be part of the bundle.
+
+### ** Linux/WSL **
+
+It's very likely that you already have Git installed. If not, use one of the following commands:
+
+* Debian / Ubuntu / Devuan: `sudo apt install -y git`
+* Fedora / Red Hat / CentOS: `sudo yum -y install git`
+* Arch / Manjaro: `sudo pacman --needed --noconfirm -S git`
+* Void: `sudo xbps-install -y git`
+* Solus: `sudo eopkg -y install git`
+* Sabayon: `sudo equo install dev-vcs/git`
+* Gentoo: `sudo emerge dev-vcs/git`
+
+<!-- tabs:end -->
+
+### 2. GitHub authentication
+
+If your GitHub account is not configured for [authenticated Git operations](https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/), you will need to setup at least one of the following:
+* [Personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token)
+* [Connecting with SSH](https://docs.github.com/en/authentication/connecting-to-github-with-ssh)
+
+### 3. Create a repository
+
+You will need a personal GitHub repository to host your QMK code. Follow [this guide](https://docs.github.com/en/get-started/quickstart/create-a-repo#create-a-repository) to create one named `qmk_keymap`. Do not proceed to commit any files just yet.
+
+
+## Initial Code Commit
+
+### Create template files
+
+Run the following commands in your computer to create a folder with a few template files:
+```
+mkdir -p ~/qmk_keymap/.github/workflows
+touch ~/qmk_keymap/.github/workflows/build.yml
+touch ~/qmk_keymap/config.h
+echo "SRC += source.c" > ~/qmk_keymap/rules.mk
+echo "#include QMK_KEYBOARD_H" > ~/qmk_keymap/source.c
+```
+
+?> For Windows user running MSYS, those commands will create the folder `qmk_keymap/` and its content in the `C:\Users\<windows_username>\qmk_keymap\` path location.
+
+### Add a JSON keymap
+
+Visit the [QMK Configurator](https://config.qmk.fm/#/) to create a keymap file:
+
+1. Select your keyboard from the drop-down list (and choose a layout if required).
+2. Use your GitHub username for the **Keymap Name** field.
+3. Customise the key layout according to your preference.
+4. Select download next to **KEYMAP.JSON** and save the JSON file into the `~/qmk_keymap/` folder.
+
+### Add a GitHub Action workflow
+
+Open the file `~/qmk_keymap/.github/workflows/build.yml` with your favorite [text editor](newbs_learn_more_resources.md#text-editor-resources), paste the following workflow content, and save it:
+```yml
+name: Build QMK firmware
+on: [push, workflow_dispatch]
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    container: qmkfm/qmk_cli
+    strategy:
+      fail-fast: false
+      matrix:
+# List of keymap json files to build
+        file:
+        - username.json
+# End of json file list
+
+    steps:
+
+    - name: Checkout QMK
+      uses: actions/checkout@v3
+      with:
+        repository: qmk/qmk_firmware
+        submodules: recursive
+
+    - name: Checkout userspace
+      uses: actions/checkout@v3
+      with:
+        path: users/${{ github.actor }}
+
+    - name: Build firmware
+      run: qmk compile "users/${{ github.actor }}/${{ matrix.file }}"
+
+    - name: Archive firmware
+      uses: actions/upload-artifact@v3
+      continue-on-error: true
+      with:
+        name: ${{ matrix.file }}_${{ github.actor }}
+        path: |
+          *.hex
+          *.bin
+          *.uf2
+```
+Replace `username.json` with the JSON file name that was downloaded from [QMK Configurator](https://config.qmk.fm/#/) in the previous step.
+
+!> Do note that the `build.yml` file requires ***proper indentation*** for every line. Incorrect spacing will trigger workflow syntax errors.
+
+### Commit files to GitHub
+
+If you have completed all steps correctly, the folder `qmk_keymap/` will contain the following files:
+```
+|-- .github
+|   `-- workflows
+|       `-- build.yml
+|-- rules.mk
+|-- config.h
+|-- source.c
+|-- username.json
+```
+
+To commit and push them into GitHub, run the following commands (replacing `gh-username` with your GitHub user name):
+```
+cd ~/qmk_keymap
+git init
+git add -A
+git commit -m "Initial QMK keymap commit"
+git branch -M main
+git remote add origin https://github.com/gh-username/qmk_keymap.git
+git push -u origin main
+```
+?> Use your GitHub personal access token at the password prompt. If you have setup SSH access, replace `https://github.com/gh-username/qmk_keymap.git` with `git@github.com:gh-username/qmk_keymap.git` in the remote origin command above.
+
+### Review workflow output
+
+Files committed to GitHub in the previous step will automatically trigger the workflow to build the JSON file listed in `build.yml`. To review its output:
+1. Visit your "**qmk_keymap**" repository page on [GitHub](https://github.com/).
+2. Select **Actions** tab to display the "**Build QMK Firmware**" workflow.
+3. Select that workflow to display its run from the last commit.
+4. Successfully compiled firmware will be under the "**Artifacts**" section.
+5. If there are build errors, review the job log for details.
+
+Download and flash the firmware file into your keyboard using [QMK Toolbox](https://docs.qmk.fm/#/newbs_flashing?id=flashing-your-keyboard-with-qmk-toolbox).
+
+
+## Customising your keymap
+
+This setup and workflow relies on the QMK [Userspace](https://docs.qmk.fm/#/feature_userspace) feature. The build process will copy the QMK source codes and clone your repository into its `users/` folder in a container. You must adhere to the following guidelines when customising your keymaps:
+
+* Keymap layout files must be retained in JSON format and cannot be converted to `keymap.c`.
+* User callback and functions (e.g. `process_record_user()`) can be placed in the `source.c` file.
+* Multiple keymap JSON files can be built in the same workflow. List them under `matrix.file:`, e.g.:
+```yml
+        file:
+        - planck.json
+        - crkbd.json
+```
+* Code changes will require Git commit into GitHub to trigger the build workflow.
+
+

+# WeAct Blackpill (STM32F411)
+
+The WeAct Blackpill is a popular choice for handwired boards, as it offers a powerful micro controller, USB Type C, a good number of pins to use, and a large amount of firmware space.  All for a ~$6 USD price tag. 
+
+* [WeAct GitHub for F411 Blackpill](https://github.com/WeActTC/MiniSTM32F4x1)
+  * Unfortunately, due to supply issues official WeAct F411 based blackpills may not be available.
+
+![Blackpill F411](https://i.imgur.com/nCgeolTh.png)
+
+
+## Pin Usage Limitations
+
+While the Blackpill is a great choice to use in your keyboard, there are a number of caveats in regards to using them.  The first is that a number of exposed pins cannot be used, or have special considerations/hardware tweaks that are required for proper opertion. 
+
+### Unusable pins
+* Pins `A11` and `A12` are not useable because they're used for USB connection, and cannot be shared.
+  * In theory, these pins can be used.  However, doing so may disable USB connectivity, outright, if used for anything other than a USB port
+* Pin `B2` is used by `BOOT1` and cannot be used, without causing problems. 
+* `VBAT` is not a usable pin.
+* `NRST` is not a usable pin.
+
+### Pins to be avoided
+* Pin `A9` is meant for VBUS Sense and should not be used, if it can be avoided.  It has an internal pull-down resesitor, which may cause issues with usage.  However, a pull-up resistor can work (~5.1k), but should be avoided.
+* Pin `A10` can be used, but should be avoided.  Any connection on this pin can prevent the bootloader from entering the proper mode for DFU flashing.  A pull-up resistor (~22k) on this pin fixes the bootloader issue. 
+
+### Shared Usage
+* Pin `A0` is shared with the User Key (button) on the controller.  It can be used. 
+* Pin `C13` is shared with the onboard LED indicator, and is connected to +3.3V.  This can be used, but may cause the LED to blink intermittently, depending on activity on the pin. 
+  * 
+* Pins `A4`, `A5`, `A6` and `A7` are used by the SOI8 footprint on the back of the controller, that can be used for either an SPI Flash chip, or an SPI EEPROM chip.  `A4` is the Chip Select pin, and cannot be shared.  However, `A5`, `A6`, and `A7` are the `SCK`, `MISO`, and `MOSI` pins, respectively, and can be shared with other SPI devices. 
+
+### Limited Usage
+* Pins `C13`, `C14`, and `C15` have limits on output current. They should be used only as input.   Eg, they should not be used for row pins in COL2ROW matrix configurations, but can be used as column pins.
+  * This is because the column pins (in COL2ROW) are pulled up (the pullup strength is independant of the current sourcing limitation) and the ROW is driven low and sinks current, then we check the state of the COLs to look for keypresses.
+
+* Pins `A0` and `B5` are not 5V tolerant, and should only be used with 3.3V compatible functionality. 
+
+## Additional Information
+
+### Bootloader issuse
+
+Due to the use of a 25MHz crystal, the controller may have issues entering the bootloader.  Heating up the controller can help with this issue. 
+
+Also, if pin `A10` is connected to anything at all, it needs to have a pullup resistor (see [Pins to be avoided](#pins-to-be-avoided), above)
+
+### Tiny UF2 Support
+
+There is [tinyuf2 support for the WeAct Blackpill](https://github.com/adafruit/tinyuf2/tree/master/ports/stm32f4/boards/stm32f411ce_blackpill).  Instructions on how to compile the bootloadr can be found [here](https://github.com/adafruit/tinyuf2#build-and-flash).  Setting `BOOTLOADER = tinyuf2` will enable support for this user bootloader, and the correct configuration to prevent it from being overwritten when flashing firmware.

+## Warnings
+
+Some of the PCBs compatible with Pro Micro have VCC (3.3V) and RAW (5V) pins connected (shorted) on the pcb. Using the Proton C will short 5V power from USB and regulated 3.3V which is connected directly to the MCU. Shorting those pins may damage the MCU on the Proton C.
+
+So far, it appears that this is only an issue on the Gherkin PCBs, but other PCBs may be affected in this way.
+
+In this case, you may want to not hook up the RAW pin at all.
+
+## Manual Conversion
+
+To use the Proton C natively, without having to specify `CONVERT_TO=proton_c`, you need to change the `MCU` line in `rules.mk`:
+
+```
+MCU = STM32F303
+BOARD = QMK_PROTON_C
+```
+
+Remove these variables if they exist:
+
+* `BOOTLOADER`
+* `EXTRA_FLAGS`
+
+Finally convert all pin assignments in `config.h` to the stm32 equivalents.
+
+| Pro Micro Left | Proton C Left | | Proton C Right | Pro Micro Right |
+|-----------|----------|-|----------|-----------|
+| `D3` | `A9` | | 5v | RAW (5v) |
+| `D2` | `A10` | | GND | GND |
+| GND | GND | | FLASH | RESET |
+| GND | GND | | 3.3v | VCC <sup>1</sup> |
+| `D1` | `B7` | | `A2` | `F4` |
+| `D0` | `B6` | | `A1` | `F5` |
+| `D4` | `B5` | | `A0` | `F6` |
+| `C6` | `B4` | | `B8` | `F7` |
+| `D7` | `B3` | | `B13` | `B1` |
+| `E6` | `B2` | | `B14` | `B3` |
+| `B4` | `B1` | | `B15` | `B2` |
+| `B5` | `B0` | | `B9` | `B6` |
+| `B0` (RX LED) | `C13` <sup>2</sup> | | `C13` <sup>2</sup> | `D5` (TX LED) |
+
+You can also make use of several new pins on the extended portion of the Proton C:
+
+| Left | | Right | 
+|------|-|-------|
+| `A4`<sup>3</sup> | | `B10` |
+| `A5`<sup>4</sup> | | `B11` |
+| `A6` | | `B12` |
+| `A7` | | `A14`<sup>5</sup> (SWCLK) |
+| `A8` | | `A13`<sup>5</sup> (SWDIO) |
+| `A15` | | RESET<sup>6</sup> |
+
+Notes:
+
+1. On a Pro Micro VCC can be 3.3v or 5v.
+2. A Proton C only has one onboard LED, not two like a Pro Micro. The Pro Micro has an RX LED on `D5` and a TX LED on `B0`.
+3. `A4` is shared with the speaker.
+4. `A5` is shared with the speaker.
+5. `A13` and `A14` are used for hardware debugging (SWD). You can also use them for GPIO, but should use them last.
+6. Short RESET to 3.3v (pull high) to reboot the MCU. This does not enter bootloader mode like a Pro Micro, it only resets the MCU.

+
+!> The GPIO pins of the RP2040 are not 5V tolerant!
+
+### Pin nomenclature
+
+To address individual pins on the RP2040, QMK uses the `GPx` abbreviation -- where the `x` stands for the GPIO number of the pin. This number can likely be found on the official pinout diagram of your board. Note that these GPIO numbers match the RP2040 MCU datasheet, and don't necessarily match the number you see printed on the board. For instance the Raspberry Pi Pico uses numbers from 1 to 40 for their pins, but these are not identical to the RP2040's GPIO numbers. So if you want to use the pin 11 of the Pico for your keyboard, you would refer to it as `GP8` in the config files.
+
+### Alternate functions
+
+The RP2040 features flexible GPIO function multiplexing, this means that every pin can be connected to nearly all the internal peripherals like I2C, SPI, UART or PWM. This allows for flexible PCB designs that are much less restricted in the selection of GPIO pins. To find out which pin can use which peripheral refer to the official [Raspberry PI RP2040 datasheet](https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.pdf#page=14) section 1.4.3 GPIO functions.
+
+## Selecting hardware peripherals and drivers
+
+QMK RP2040 support builds upon ChibiOS and thus follows their convention for activating drivers and associated hardware peripherals. These tables only give a quick overview which values have to be used, please refer to the ChibiOS specific sections on the driver pages.
+
+### I2C Driver
+
+| RP2040 Peripheral | `mcuconf.h` values | `I2C_DRIVER` |
+| ----------------- | ------------------ | ------------ |
+| `I2C0`            | `RP_I2C_USE_I2C0`  | `I2CD1`      |
+| `I2C1`            | `RP_I2C_USE_I2C1`  | `I2CD2`      |
+
+To configure the I2C driver please read the [ChibiOS/ARM](i2c_driver.md#arm-configuration) section.
+
+### SPI Driver
+
+| RP2040 Peripheral | `mcuconf.h` values | `SPI_DRIVER` |
+| ----------------- | ------------------ | ------------ |
+| `SPI0`            | `RP_SPI_USE_SPI0`  | `SPID0`      |
+| `SPI1`            | `RP_SPI_USE_SPI1`  | `SPID1`      |
+
+To configure the SPI driver please read the [ChibiOS/ARM](spi_driver.md#chibiosarm-configuration) section.
+
+## Double-tap reset boot-loader entry :id=double-tap
+
+The double-tap reset mechanism is an alternate way in QMK to enter the embedded mass storage UF2 boot-loader of the RP2040. It enables bootloader entry by a fast double-tap of the reset pin on start up, which is similar to the behavior of AVR Pro Micros. This feature activated by default for the Pro Micro RP2040 board, but has to be configured for other boards. To activate it, add the following options to your keyboards `config.h` file:
+
+```c
+#define RP2040_BOOTLOADER_DOUBLE_TAP_RESET // Activates the double-tap behavior
+#define RP2040_BOOTLOADER_DOUBLE_TAP_RESET_TIMEOUT 200U // Timeout window in ms in which the double tap can occur.
+#define RP2040_BOOTLOADER_DOUBLE_TAP_RESET_LED_MASK 0U // Specify a optional status led which blinks when entering the bootloader
+```
+
+## Pre-defined RP2040 boards
+
+QMK defines two boards that you can choose from to base your RP2040 powered keyboard upon. These boards provide pre-configured default pins and drivers.
+
+### Generic Pro Micro RP2040
+
+This is the default board that is chosen, unless any other RP2040 board is selected in your keyboards `rules.mk` file. It assumes a pin layout for the I2C, SPI and Serial drivers which is identical to the Sparkfun Pro Micro RP2040, however all values can be overwritten by defining them in your keyboards `config.h` file. The [double-tap](#double-tap) reset to enter boot-loader behavior is activated by default.

+?> The pin-outs of Adafruit's KB2040 and Boardsource's Blok both deviate from the Sparkfun Pro Micro RP2040. Lookup the pin-out of these boards and adjust your keyboards pin definition accordingly if you want to use these boards.
+
+### Generic RP2040 board
+
+This board can be chosen as a base for RP2040 keyboards which configure all necessary pins and drivers themselves and do not wish to leverage the configuration matching the Generic Pro Micro RP2040 board. Thus it doesn't provide any pre-configured pins or drivers. To select this board add the following line to your keyboards `rules.mk` file.
+
+```make
+BOARD = GENERIC_RP_RP2040
+```
+
+## Split keyboard support
+
+Split keyboards are fully supported using the [serial driver](serial_driver.md) in both full-duplex and half-duplex configurations. Two driver subsystems are supported by the RP2040, the hardware UART based `SIO` and the Programmable IO based `PIO` driver.
+
+| Feature                       | [SIO Driver](serial_driver.md#the-sio-driver) | [PIO Driver](serial_driver.md#the-pio-driver) |
+| ----------------------------- | --------------------------------------------- | --------------------------------------------- |
+| Half-Duplex operation         |                                               | :heavy_check_mark:                            |
+| Full-Duplex operation         | :heavy_check_mark:                            | :heavy_check_mark:                            |
+| `TX` and `RX` pin swapping    |                                               | :heavy_check_mark:                            |
+| Any GPIO as `TX` and `RX` pin | Only UART capable pins                        | :heavy_check_mark:                            |
+| Simple configuration          |                                               | :heavy_check_mark:                            |
+
+The `PIO` driver is much more flexible then the `SIO` driver, the only "downside" is the usage of `PIO` resources which in turn are not available for advanced user programs. Under normal circumstances, this resource allocation will be a non-issue.
+
+## RP2040 second stage bootloader selection
+
+As the RP2040 does not have any internal flash memory it depends on an external SPI flash memory chip to store and execute instructions from. To successfully interact with a wide variety of these chips a second stage bootloader that is compatible with the chosen external flash memory has to be supplied with each firmware image. By default an `W25Q080` compatible bootloader is assumed, but others can be chosen by adding one of the defines listed in the table below to your keyboards `config.h` file. 
+
+| Compatible with flash chip | Selection                          |
+| :------------------------- | ---------------------------------- |
+| W25Q080                    | Selected by default                |
+| AT25SF128A                 | `#define RP2040_FLASH_AT25SF128A`  |
+| GD25Q64CS                  | `#define RP2040_FLASH_GD25Q64CS`   |
+| W25X10CL                   | `#define RP2040_FLASH_W25X10CL`    |
+| IS25LP080                  | `#define RP2040_FLASH_IS25LP080`   |
+| Generic 03H flash          | `#define RP2040_FLASH_GENERIC_03H` |

-# Converting a board to use the Proton C
-
-Since the Proton C is a drop-in replacement for a Pro Micro we've made it easy to use. This page documents a handy automated process for converting keyboards, as well as documenting the manual process if you'd like to make use of Proton C features that aren't available on Pro Micros.
-
-## Automatic Conversion
-
-If a board currently supported in QMK uses a Pro Micro (or compatible board) and you want to use the Proton C, you can generate the firmware by appending `CONVERT_TO_PROTON_C=yes` (or `CTPC=yes`) to your make argument, like this:
-
-    make 40percentclub/mf68:default CTPC=yes
-
-You can add the same argument to your keymap's `rules.mk`, which will accomplish the same thing.
-
-This exposes the `CONVERT_TO_PROTON_C` flag that you can use in your code with `#ifdef`s, like this:
-
-```c
-#ifdef CONVERT_TO_PROTON_C
-    // Proton C code
-#else
-    // Pro Micro code
-#endif
-```
-
-If you get errors about `PORTB/DDRB`, etc not being defined, so you'll need to convert the keyboard's code to use the [GPIO Controls](gpio_control.md) that will work for both ARM and AVR. This shouldn't affect the AVR builds at all.
-
-The Proton C only has one on-board LED (C13), and by default, the TXLED (D5) is mapped to it. If you want the RXLED (B0) mapped to it instead, add this like to your `config.h`:
-
-    #define CONVERT_TO_PROTON_C_RXLED
-
-## Feature Conversion
-
-These are defaults based on what has been implemented for ARM boards.

-## Manual Conversion
-
-To use the Proton C natively, without having to specify `CTPC=yes`, you need to change the `MCU` line in `rules.mk`:
-
-```
-MCU = STM32F303
-BOARD = QMK_PROTON_C
-```
-
-Remove these variables if they exist:
-
-* `BOOTLOADER`
-* `EXTRA_FLAGS`
-
-Finally convert all pin assignments in `config.h` to the stm32 equivalents.
-
-| Pro Micro Left | Proton C Left | | Proton C Right | Pro Micro Right |
-|-----------|----------|-|----------|-----------|
-| `D3` | `A9` | | 5v | RAW (5v) |
-| `D2` | `A10` | | GND | GND |
-| GND | GND | | FLASH | RESET |
-| GND | GND | | 3.3v | VCC <sup>1</sup> |
-| `D1` | `B7` | | `A2` | `F4` |
-| `D0` | `B6` | | `A1` | `F5` |
-| `D4` | `B5` | | `A0` | `F6` |
-| `C6` | `B4` | | `B8` | `F7` |
-| `D7` | `B3` | | `B13` | `B1` |
-| `E6` | `B2` | | `B14` | `B3` |
-| `B4` | `B1` | | `B15` | `B2` |
-| `B5` | `B0` | | `B9` | `B6` |
-| `B0` (RX LED) | `C13` <sup>2</sup> | | `C13` <sup>2</sup> | `D5` (TX LED) |
-
-You can also make use of several new pins on the extended portion of the Proton C:
-
-| Left | | Right | 
-|------|-|-------|
-| `A4`<sup>3</sup> | | `B10` |
-| `A5`<sup>4</sup> | | `B11` |
-| `A6` | | `B12` |
-| `A7` | | `A14`<sup>5</sup> (SWCLK) |
-| `A8` | | `A13`<sup>5</sup> (SWDIO) |
-| `A15` | | RESET<sup>6</sup> |
-
-Notes:
-
-1. On a Pro Micro VCC can be 3.3v or 5v.
-2. A Proton C only has one onboard LED, not two like a Pro Micro. The Pro Micro has an RX LED on `D5` and a TX LED on `B0`.
-3. `A4` is shared with the speaker.
-4. `A5` is shared with the speaker.
-5. `A13` and `A14` are used for hardware debugging (SWD). You can also use them for GPIO, but should use them last.
-6. Short RESET to 3.3v (pull high) to reboot the MCU. This does not enter bootloader mode like a Pro Micro, it only resets the MCU.

+This is the Default driver, the absence of configuration assumes this driver. It works by [bit banging](https://en.wikipedia.org/wiki/Bit_banging) a GPIO pin using the CPU. It is therefore not as efficient as a dedicated hardware peripheral, which the Half-duplex and Full-duplex drivers use.
 
-## Driver configuration
+!> On ARM platforms the bitbang driver causes connection issues when using it together with the bitbang WS2812 driver. Choosing alternate drivers for both serial and WS2812 (instead of bitbang) is strongly recommended.
 
-### Bitbang
-Default driver, the absence of configuration assumes this driver. To configure it, add this to your rules.mk:
+### Pin configuration
+
+```
+  LEFT                      RIGHT
++-------+      SERIAL     +-------+
+|   SSP |-----------------| SSP   |

+|       |-----------------|       |
++-------+                 +-------+
+```
+
+One GPIO pin is needed for the bitbang driver, as only one wire is used for receiving and transmitting data. This pin is referred to as the `SOFT_SERIAL_PIN` (SSP) in the configuration. A simple TRS or USB cable provides enough conductors for this driver to work. 
+
+### Setup
+
+To use the bitbang driver follow these steps to activate it.
+
+1. Change the `SERIAL_DRIVER` to `bitbang` in your keyboards `rules.mk` file:
 
 ```make
 SERIAL_DRIVER = bitbang
 ```
 
-Configure the driver via your config.h:
+2. Configure the GPIO pin of your keyboard via the `config.h` file:
+
 ```c
 #define SOFT_SERIAL_PIN D0  // or D1, D2, D3, E6
-#define SELECT_SOFT_SERIAL_SPEED 1 // or 0, 2, 3, 4, 5
-                                   //  0: about 189kbps (Experimental only)
-                                   //  1: about 137kbps (default)
-                                   //  2: about 75kbps
-                                   //  3: about 39kbps
-                                   //  4: about 26kbps
-                                   //  5: about 20kbps
 ```
 
-#### ARM
+3. On ARM platforms you must turn on ChibiOS `PAL_USE_CALLBACKS` feature:
 
-!> The bitbang driver causes connection issues with bitbang WS2812 driver
+* In `halconf.h` add the line `#define PAL_USE_CALLBACKS TRUE`.
 
-Along with the generic options above, you must also turn on the `PAL_USE_CALLBACKS` feature in your halconf.h.
+<hr>
 
-### USART Half-duplex
-Targeting STM32 boards where communication is offloaded to a USART hardware device. The advantage over bitbang is that this provides fast and accurate timings. `SERIAL_PIN_TX` for this driver is the configured USART TX pin. As this Pin is configured in open-drain mode an **external pull-up resistor is needed to keep the line high** (resistor values of 1.5k to 8.2k are known to work). To configure it, add this to your rules.mk:
+## USART Half-duplex
+
+Targeting ARM boards based on ChibiOS, where communication is offloaded to a USART hardware device that supports Half-duplex operation. The advantages over bitbanging are fast, accurate timings and reduced CPU usage. Therefore it is advised to choose this driver or the Full-duplex driver whenever possible.

+```
+
+Only one GPIO pin is needed for the Half-duplex driver, as only one wire is used for receiving and transmitting data. This pin is referred to as the `SERIAL_USART_TX_PIN` in the configuration. Take care that the pin you chose can act as the TX pin of the USART peripheral. A simple TRS or USB cable provides enough conductors for this driver to work. As the split connection is configured to work in open-drain mode, an **external pull-up resistor is needed to keep the line high**. Resistor values of 1.5kΩ to 8.2kΩ are known to work.
+
+### Setup
+
+To use the Half-duplex driver follow these steps to activate it. If you target the Raspberry Pi RP2040 PIO implementation skip step 1.
+
+1. Change the `SERIAL_DRIVER` to `usart` in your keyboards `rules.mk` file:
 
 ```make
 SERIAL_DRIVER = usart

-### USART Full-duplex
-Targeting STM32 boards where communication is offloaded to a USART hardware device. The advantage over bitbang is that this provides fast and accurate timings. USART Full-Duplex requires two conductors **without** pull-up resistors instead of one conductor with a pull-up resistor unlike the Half-duplex driver. Due to its internal design it is more efficent, which can result in even faster transmission speeds.
+1. Decide either for `SERIAL`, `SIO` or `PIO` subsystem, see the section ["Choosing a driver subsystem"](#choosing-a-driver-subsystem).
 
-#### Pin configuration
+<hr>
 
-`SERIAL_USART_TX_PIN` is the USART `TX` pin, `SERIAL_USART_RX_PIN` is the USART `RX` pin. No external pull-up resistors are needed as the `TX` pin operates in push-pull mode. To use this driver the usart peripherals `TX` and `RX` pins must be configured with the correct Alternate-functions. If you are using a Proton-C everything is already setup, same is true for STM32F103 MCUs. For MCUs which are using a modern flexible GPIO configuration you have to specify these by setting `SERIAL_USART_TX_PAL_MODE` and `SERIAL_USART_RX_PAL_MODE`. Refeer to the corresponding datasheets of your MCU or find those settings in the table below.
+## USART Full-duplex
 
-#### Connecting the halves and Pin Swap
-Please note that `TX` of the master half has to be connected with the `RX` pin of the slave half and `RX` of the master half has to be connected with the `TX` pin of the slave half! Usually this pin swap has to be done outside of the MCU e.g. with cables or on the pcb. Some MCUs like the STM32F303 used on the Proton-C allow this pin swap directly inside the MCU, this feature can be enabled using `#define SERIAL_USART_PIN_SWAP` in your config.h.
+Targeting ARM boards based on ChibiOS where communication is offloaded to an USART hardware device. The advantages over bitbanging are fast, accurate timings and reduced CPU usage. Therefore it is advised to choose this driver or the Full-duplex driver whenever possible. Due to its internal design it is slightly more efficient then the Half-duplex driver, but it should be primarily chosen if Half-duplex operation is not supported by the USART peripheral.
 
-#### Setup
-To use the driver, add this to your rules.mk:
+### Pin configuration
+
+```

++-------+                 +-------+
+```
+
+Two GPIO pins are needed for the Full-duplex driver, as two distinct wires are used for receiving and transmitting data. The pin transmitting data is the `TX` pin and refereed to as the `SERIAL_USART_TX_PIN`, the pin receiving data is the `RX` pin and refereed to as the `SERIAL_USART_RX_PIN` in this configuration. Please note that `TX` pin of the master half has to be connected with the `RX` pin of the slave half and the `RX` pin of the master half has to be connected with the `TX` pin of the slave half! Usually this pin swap has to be done outside of the MCU e.g. with cables or on the PCB. Some MCUs like the STM32F303 used on the Proton-C allow this pin swap directly inside the MCU. A simple TRRS or USB cable provides enough conductors for this driver to work.
+
+To use this driver the usart peripherals `TX` and `RX` pins must be configured with the correct Alternate-functions. If you are using a Proton-C everything is already setup, same is true for STM32F103 MCUs. For MCUs which are using a modern flexible GPIO configuration you have to specify these by setting `SERIAL_USART_TX_PAL_MODE` and `SERIAL_USART_RX_PAL_MODE`. Refer to the corresponding datasheets of your MCU or find those settings in the section ["Alternate Functions for selected STM32 MCUs"](#alternate-functions-for-selected-stm32-mcus).
+
+### Setup
+
+To use the Full-duplex driver follow these steps to activate it. If you target the Raspberry Pi RP2040 PIO implementation skip step 1.
+
+1. Change the `SERIAL_DRIVER` to `usart` in your keyboards `rules.mk` file:
 
 ```make
 SERIAL_DRIVER = usart
 ```
 
-Next configure the hardware via your config.h:
+2. (RP2040 PIO only!) Change the `SERIAL_DRIVER` to `vendor` in your keyboards `rules.mk` file:
+
+```make
+SERIAL_DRIVER = vendor
+```
+
+3. Configure the hardware of your keyboard via the `config.h` file:
 
 ```c
 #define SERIAL_USART_FULL_DUPLEX   // Enable full duplex operation mode.
 #define SERIAL_USART_TX_PIN B6     // USART TX pin
 #define SERIAL_USART_RX_PIN B7     // USART RX pin
-//#define USART1_REMAP             // Remap USART TX and RX pins on STM32F103 MCUs, see table below.
-//#define SERIAL_USART_PIN_SWAP    // Swap TX and RX pins if keyboard is master halve.
-                                   // Check if this feature is necessary with your keyboard design and available on the mcu.
-#define SELECT_SOFT_SERIAL_SPEED 1 // or 0, 2, 3, 4, 5
-                                   //  0: 460800 baud
-                                   //  1: 230400 baud (default)
-                                   //  2: 115200 baud
-                                   //  3: 57600 baud
-                                   //  4: 38400 baud
-                                   //  5: 19200 baud
-#define SERIAL_USART_DRIVER SD1    // USART driver of TX and RX pin. default: SD1
+```
+
+For STM32 MCUs several GPIO configuration options, including the ability for `TX` to `RX` pin swapping, can be changed as well. See the section ["Alternate Functions for selected STM32 MCUs"](alternate-functions-for-selected-stm32-mcus).
+
+```c
+#define SERIAL_USART_PIN_SWAP      // Swap TX and RX pins if keyboard is master halve. (Only available on some MCUs)
+#define USART1_REMAP               // Remap USART TX and RX pins on STM32F103 MCUs, see table below.
 #define SERIAL_USART_TX_PAL_MODE 7 // Pin "alternate function", see the respective datasheet for the appropriate values for your MCU. default: 7
-#define SERIAL_USART_RX_PAL_MODE 7 // Pin "alternate function", see the respective datasheet for the appropriate values for your MCU. default: 7
+```
+
+1. Decide either for `SERIAL`, `SIO` or `PIO` subsystem, see the section ["Choosing a driver subsystem"](#choosing-a-driver-subsystem).
+
+<hr>
+
+## Choosing a driver subsystem
+
+### The `SERIAL` driver
+
+The `SERIAL` Subsystem is supported for the majority of ChibiOS MCUs and should be used whenever supported. Follow these steps in order to activate it:
+
+1. In your keyboards `halconf.h` add:
+
+```c
+#define HAL_USE_SERIAL TRUE
+```
+
+2. In your keyboards `mcuconf.h`: activate the USART peripheral that is used on your MCU. The shown example is for an STM32 MCU, so this will not work on MCUs by other manufacturers. You can find the correct names in the `mcuconf.h` files of your MCU that ship with ChibiOS. 
+ 
+Just below `#include_next <mcuconf.h>` add:
+
+```c
+#include_next <mcuconf.h>
+
+#undef STM32_SERIAL_USE_USARTn
+#define STM32_SERIAL_USE_USARTn TRUE
+```
+
+Where 'n' matches the peripheral number of your selected USART on the MCU.
+
+3. In you keyboards `config.h`: override the default USART `SERIAL` driver if you use a USART peripheral that does not belong to the default selected `SD1` driver. For instance, if you selected `STM32_SERIAL_USE_USART3` the matching driver would be `SD3`.
+
+```c
+ #define SERIAL_USART_DRIVER SD3
+ ```
+
+### The `SIO` driver
+
+The `SIO` Subsystem was added to ChibiOS with the 21.11 release and is only supported on selected MCUs. It should only be chosen when the `SERIAL` subsystem is not supported by your MCU.
+
+Follow these steps in order to activate it:
+
+1. In your keyboards `halconf.h` add:
+
+```c
+#define HAL_USE_SIO TRUE
+```
+
+2. In your keyboards `mcuconf.h:` activate the USART peripheral that is used on your MCU. The shown example is for an STM32 MCU, so this will not work on MCUs by other manufacturers. You can find the correct names in the `mcuconf.h` files of your MCU that ship with ChibiOS. 
+ 
+Just below `#include_next <mcuconf.h>` add:
+
+```c
+#include_next <mcuconf.h>
+
+#undef STM32_SIO_USE_USARTn
+#define STM32_SIO_USE_USARTn TRUE
+```
+
+Where 'n' matches the peripheral number of your selected USART on the MCU.
+
+3. In you keyboards `config.h`: override the default USART `SIO` driver if you use a USART peripheral that does not belong to the default selected `SIOD1` driver. For instance, if you selected `STM32_SERIAL_USE_USART3` the matching driver would be `SIOD3`.
+
+```c
+ #define SERIAL_USART_DRIVER SIOD3
+ ```
+ 
+### The `PIO` driver
+
+The `PIO` subsystem is a Raspberry Pi RP2040 specific implementation, using the integrated PIO peripheral and is therefore only available on this MCU. Because of the flexible nature of the PIO peripherals, **any** GPIO pin can be used as a `TX` or `RX` pin. Half-duplex and Full-duplex operation is fully supported. The Half-duplex operation mode uses the built-in pull-ups and GPIO manipulation on the RP2040 to drive the line high by default. An external pull-up is therefore not necessary.
+
+Configure the hardware via your config.h:
+```c
+#define SERIAL_PIO_USE_PIO1 // Force the usage of PIO1 peripheral, by default the Serial implementation uses the PIO0 peripheral
+```
+
+The Serial PIO program uses 2 state machines, 13 instructions and the complete interrupt handler of the PIO peripheral it is running on.
+
+<hr>
+
+## Advanced Configuration
+
+There are several advanced configuration options that can be defined in your keyboards `config.h` file:
+
+### Baudrate
+
+If you're having issues or need a higher baudrate with serial communication, you can change the baudrate which in turn controls the communication speed for serial. You want to lower the baudrate if you experience failed transactions. 
+
+```c
+#define SELECT_SOFT_SERIAL_SPEED {#}
+```
+
+| Speed | Bitbang                    | Half-duplex and Full-duplex |
+| ----- | -------------------------- | --------------------------- |
+| `0`   | 189000 baud (experimental) | 460800 baud                 |
+| `1`   | 137000 baud (default)      | 230400 baud (default)       |
+| `2`   | 75000 baud                 | 115200 baud                 |
+| `3`   | 39000 baud                 | 57600 baud                  |
+| `4`   | 26000 baud                 | 38400 baud                  |
+| `5`   | 20000 baud                 | 19200 baud                  |
+
+Alternatively you can specify the baudrate directly by defining `SERIAL_USART_SPEED`.
+
+### Timeout
+
+This is the default time window in milliseconds in which a successful communication has to complete. Usually you don't want to change this value. But you can do so anyways by defining an alternate one in your keyboards `config.h` file:
+
+```c
 #define SERIAL_USART_TIMEOUT 20    // USART driver timeout. default 20
 ```
 
-You must also enable the ChibiOS `SERIAL` feature:
-* In your board's halconf.h: `#define HAL_USE_SERIAL TRUE`
-* In your board's mcuconf.h: `#define STM32_SERIAL_USE_USARTn TRUE` (where 'n' matches the peripheral number of your selected USART on the MCU)
+<hr>
 
-Do note that the configuration required is for the `SERIAL` peripheral, not the `UART` peripheral.

+### PIO
+
+Targeting Raspberry Pi RP2040 boards only where WS2812 support is offloaded to an dedicated PIO implementation. This offloads processing of the WS2812 protocol from the MCU to a dedicated PIO program using DMA transfers.
+
+To configure it, add this to your rules.mk:
+
+```make
+WS2812_DRIVER = vendor
+```
+
+Configure the hardware via your config.h:
+```c
+#define WS2812_PIO_USE_PIO1 // Force the usage of PIO1 peripheral, by default the WS2812 implementation uses the PIO0 peripheral
+```
+
+The WS2812 PIO programm uses 1 state machine, 4 instructions and does not use any interrupt handlers. 
+
 ### Push Pull and Open Drain Configuration
 The default configuration is a push pull on the defined pin.
 This can be configured for bitbang, PWM and SPI.
