+# 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`            |
+
+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
+```

 If the LEDs start blinking during the recording with each keypress, it means there is no more space for the macro in the macro buffer. To fit the macro in, either make the other macro shorter (they share the same buffer) or increase the buffer size by adding the `DYNAMIC_MACRO_SIZE` define in your `config.h` (default value: 128; please read the comments for it in the header).

 Sometimes you want a key to type out words or phrases. For the most common situations, we've provided `SEND_STRING()`, which will type out a string (i.e. a sequence of characters) for you. All ASCII characters that are easily translatable to a keycode are supported (e.g. `qmk 123\n\t`).

 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.

+# 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
+
+Once unlocked, the keyboard will revert back to a locked state after the configured timeout.
+The timeout can be refreshed by using the `secure_activity_event` function, for example from one of the various [hooks](custom_quantum_functions.md).

+# 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

+### 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 :id=tx-bolt
 
-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_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.

+Similar to the first option, the second and third option are good for simple layer-switching cases.
 
-For more complicated cases, use the third or fourth options (examples of each are listed below).
-
-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.
+For more complicated cases, like blink the LEDs, fiddle with the backlighting, and so on, use the fourth or fifth option. Examples of each are listed below.
 
 ## 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`:
-
-    TERMINAL_ENABLE = yes
-
-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.
-
-`#define TERMINAL_HELP` enables some other output helpers that aren't really needed with this page.

-
-* Keyboard/user-extensible commands
-* Smaller footprint
-* Arrow key support
-* Command history - Done
-* SD card support
-* LCD support for buffer display
-* Keycode -> name string LUT

+# Proton C
+
+The Proton C is an Arm STM32F303xC based drop-in replacement for the Pro Micro.
+
+<img src="https://i.imgur.com/GdsN1Rdh.jpg" alt="Proton C" />
+
+#### Features
+
+* Through-hole mounted USB-C Port
+* 32-bit 72MHz Cortex-M4 processor (STM32F303CCT6)
+* I2C, SPI, PWM, DMA, DAC, USART, I2S
+* 23x 3.3V I/O Ports
+* 1x 5V output for WS2812 LED chains
+* 256kB flash
+* 40kB RAM
+* AST1109MLTRQ speaker footprint
+* Reset button
+
+## 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.
+

+| `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.
-

-|-----------|----------|-|----------|-----------|
-| `D3` | `A9` | | 5v | RAW (5v) |

-| GND | GND | | FLASH | RESET |
-| GND | GND | | 3.3v | VCC <sup>1</sup> |

-| `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

-### 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:

+
+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.

-#define SERIAL_USART_TIMEOUT 20    // USART driver timeout. default 20
+#define SERIAL_USART_TX_PIN B6     // The GPIO pin that is used split communication.
 ```
 
-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)
+For STM32 MCUs several GPIO configuration options can be changed as well. See the section ["Alternate Functions for selected STM32 MCUs"](alternate-functions-for-selected-stm32-mcus).
 
-Do note that the configuration required is for the `SERIAL` peripheral, not the `UART` peripheral.
+```c
+#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
+```
 
-### 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.

+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.

+
+## 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.

 Some variants of the WS2812 may have their color components in a different physical or logical order. For example, the WS2812B-2020 has physically swapped red and green LEDs, which causes the wrong color to be displayed, because the default order of the bytes sent over the wire is defined as GRB.
