+# QMK Breaking Changes - 2021 May 29 Changelog
+
+## Notable Changes :id=notable-changes
+
+### RGB Matrix support for split common ([#11055](https://github.com/qmk/qmk_firmware/pull/11055)) :id=rgb-matrix-split-common
+
+Split boards can now use RGB Matrix without defining a custom matrix.
+
+### Teensy 3.6 support ([#12258](https://github.com/qmk/qmk_firmware/pull/12258)) :id=teensy-3-6-support
+
+Added support for MK66F18 (Teensy 3.6) microcontroller.
+
+### New command: qmk console ([#12828](https://github.com/qmk/qmk_firmware/pull/12828)) :id=new-command-qmk-console
+
+A new `qmk console` command has been added for attaching to your keyboard's console. It operates similiarly to QMK Toolbox by allowing you to connect to one or more keyboard consoles to display debugging messages.
+
+### Improved command: qmk config :id=improve-command-qmk-config
+
+We've updated the `qmk config` command to show only the configuration items you have actually set. You can now display (almost) all of the available configuration options, along with their default values, using `qmk config -a`.
+
+### LED Matrix Improvements ([#12509](https://github.com/qmk/qmk_firmware/pull/12509), [#12580](https://github.com/qmk/qmk_firmware/pull/12580), [#12588](https://github.com/qmk/qmk_firmware/pull/12588), [#12633](https://github.com/qmk/qmk_firmware/pull/12633), [#12651](https://github.com/qmk/qmk_firmware/pull/12651), [#12685](https://github.com/qmk/qmk_firmware/pull/12685)) :id=led-matrix-improvements
+
+LED Matrix has been improved with effects, CIE1931 curves, and a task system.
+
+## Changes Requiring User Action :id=changes-requiring-user-action
+
+### Updated Keyboard Codebases :id=updated-keyboard-codebases
+
+* Durgod keyboard refactor in preparation for adding additional durgod keyboards ([#11978](https://github.com/qmk/qmk_firmware/pull/11978))
+* Updated Function96 with V2 files and removed chconf.h and halconf.h ([#12613](https://github.com/qmk/qmk_firmware/pull/12613))
+* [Keyboard] updated a vendor name / fixed minor keymap issues ([#12881](https://github.com/qmk/qmk_firmware/pull/12881))
+* [Keyboard] Corne - Remove legacy revision support ([#12226](https://github.com/qmk/qmk_firmware/pull/12226))
+
+The following keyboards have had their source moved within QMK:
+
+Old Keyboard Name | New Keyboard Name
+:---------------- | :----------------
+crkbd/rev1/common | crkbd/rev1
+function96 | function96/v1
+nckiibs/flatbread60 | delikeeb/flatbread60
+nckiibs/vaguettelite | delikeeb/vaguettelite
+nckiibs/vanana/rev1 | delikeeb/vanana/rev1
+nckiibs/vanana/rev2 | delikeeb/vanana/rev2
+nckiibs/vaneela | delikeeb/vaneela
+nckiibs/vaneelaex | delikeeb/vaneelaex
+nckiibs/waaffle/rev3/elite_c | delikeeb/waaffle/rev3/elite_c
+nckiibs/waaffle/rev3/pro_micro | delikeeb/waaffle/rev3/pro_micro
+
+The [Function96 V2](https://github.com/qmk/qmk_firmware/tree/0.13.0/keyboards/function96/v2) has also been added as part of these changes.
+
+The codebase for the [Durgod K320](https://github.com/qmk/qmk_firmware/tree/0.13.0/keyboards/durgod/k320) has been reworked in anticipation of additional Durgod keyboards gaining QMK support.
+
+Additionally, the `crkbd/rev1/legacy` keyboard has been removed.
+
+### Bootmagic Deprecation and Refactor ([#12172](https://github.com/qmk/qmk_firmware/pull/12172)) :id=bootmagic-deprecation-and-refactor
+
+QMK has decided to deprecate the full Bootmagic feature and leave Bootmagic Lite as the only remaining option.
+
+This pull request changes the behavior of `BOOTMAGIC_ENABLE` such that specifying `BOOTMAGIC_ENABLE = yes` enables Bootmagic Lite instead of full Bootmagic.
+
+If attempts to use Bootmagic functionality result in unexpected behavior, check your `rules.mk` file and change the `BOOTMAGIC_ENABLE` setting to specify either `lite` or `full`.
+
+#### Tentative Deprecation Schedule
+
+This is the current planned roadmap for the behavior of `BOOTMAGIC_ENABLE`:
+
+- From 2021 May 29, setting `BOOTMAGIC_ENABLE = yes` will enable Bootmagic Lite instead of full Bootmagic.
+- From 2021 Aug 28, `BOOTMAGIC_ENABLE` must be either `yes`, `lite`, or `no` – setting `BOOTMAGIC_ENABLE = full` will cause compilation to fail.
+- From 2021 Nov 27, `BOOTMAGIC_ENABLE` must be either `yes` or `no` – setting `BOOTMAGIC_ENABLE = lite` will cause compilation to fail.
+
+### Removal of LAYOUT_kc ([#12160](https://github.com/qmk/qmk_firmware/pull/12160)) :id=removal-of-layout-kc
+
+We've removed support for `LAYOUT_kc` macros, if your keymap uses one you will need to update it use a regular `LAYOUT` macro.
+
+### Encoder callbacks are now boolean ([#12805](https://github.com/qmk/qmk_firmware/pull/12805), [#12985](https://github.com/qmk/qmk_firmware/pull/12985)) :id=encoder-callback-boolean
+
+To allow for keyboards to override (or not) keymap level code the `encoder_update_kb` function has been changed from `void` to `bool`. You will need to update your function definition to reflect this and ensure that you return a `true` or `false` value.
+
+Example code before change:
+
+```c
+void encoder_update_kb(uint8_t index, bool clockwise) {
+    encoder_update_user(index, clockwise);
+}
+```
+
+Example code after change:
+
+```c
+bool encoder_update_kb(uint8_t index, bool clockwise) {
+    return encoder_update_user(index, clockwise);
+}
+```
+

 Also note that the F0 and F3 use different numbering schemes. The F0 has a single ADC and the channels are 0-indexed, whereas the F3 has 4 ADCs and the channels are 1-indexed. This is because the F0 uses the `ADCv1` implementation of the ADC, whereas the F3 uses the `ADCv3` implementation.

In particular, pins `F6`…`F10`, which are present at least on some STM32F103x[C-G] devices, cannot be used as ADC inputs because of this driver limitation.</sup>

+# ChibiOS Upgrade Procedure
+
+ChibiOS and ChibiOS-Contrib need to be updated in tandem -- the latter has a branch tied to the ChibiOS version in use and should not be mixed with different versions.
+
+## Getting ChibiOS
+
+* `svn` Initialisation:
+    * Only needed to be done once
+    * You might need to separately install `git-svn` package in your OS's package manager
+    * `git svn init --stdlayout --prefix='svn/' http://svn.osdn.net/svnroot/chibios/`
+    * `git remote add qmk git@github.com:qmk/ChibiOS.git`
+* Updating:
+    * `git svn fetch`
+    * First time around this will take several hours
+    * Subsequent updates will be incremental only
+* Tagging example (work out which version first!):
+    * `git tag -a ver20.3.3 -m ver20.3.3 svn/tags/ver20.3.3`
+    * `git push qmk ver20.3.3`
+    * `git tag -a breaking_YYYY_qN -m breaking_YYYY_qN svn/tags/ver20.3.3`
+    * `git push qmk breaking_YYYY_qN`
+
+## Getting ChibiOS-Contrib
+
+* `git` Initialisation:
+    * `git clone git@github.com:qmk/ChibiOS-Contrib`
+    * `git remote add upstream https://github.com/ChibiOS/ChibiOS-Contrib`
+    * `git checkout -b chibios-20.3.x upstream/chibios-20.3.x`
+* Updating:
+    * `git fetch --all --tags --prune`
+    * `git checkout chibios-20.3.x`
+    * `git pull --ff-only`
+    * `git push origin chibios-20.3.x`
+    * `git tag -a breaking_YYYY_qN -m breaking_YYYY_qN chibios-20.3.x`
+    * `git push origin breaking_YYYY_qN`
+
+## Updating submodules
+
+* Update the submodules
+    * `cd $QMK_FIRMWARE`
+    * `git checkout develop`
+    * `git pull --ff-only`
+    * `git checkout -b chibios-version-bump`
+    * `cd lib/chibios`
+    * `git fetch --all --tags --prune`
+    * `git checkout breaking_YYYY_qN`
+    * `cd ../chibios-contrib`
+    * `git fetch --all --tags --prune`
+    * `git checkout breaking_YYYY_qN`
+* Build everything
+    * `cd $QMK_FIRMWARE`
+    * `qmk multibuild -j4`
+    * Make sure there are no errors
+* Push to the repo
+    * `git commit -am 'Update ChibiOS to XXXXXXXXX'`
+    * `git push --set-upstream origin chibios-version-bump`
+* Make a PR to qmk_firmware with the new branch

+## Infinite Leader key timeout
+
+Sometimes your leader key is not on a comfortable places as the rest of keys on your sequence. Imagine that your leader key is one of your outer top right keys, you may need to reposition your hand just to reach your leader key.
+This can make typing the entire sequence on time hard even if you are able to type most of the sequence fast. For example, if your sequence is `Leader + asd` typing `asd` fast is very easy once you have your hands in your home row. However starting the sequence in time after moving your hand out of the home row to reach the leader key and back is not.
+To remove the stress this situation produces to your hands you can enable an infinite timeout just for the leader key. This mean that, after you hit the leader key you will have an infinite amount of time to start the rest of the sequence, allowing you to proper position your hands on the best position to type the rest of the sequence comfortably.
+This infinite timeout only affects the leader key, so in our previous example of `Leader + asd` you will have an infinite amount of time between `Leader` and `a`, but once you start the sequence the timeout you have configured (global or per key) will work normally.
+This way you can configure a very short `LEADER_TIMEOUT` but still have plenty of time to position your hands.
+
+In order to enable this, place this in your `config.h`:
+```c
+#define LEADER_NO_TIMEOUT
+```
+
 ## Strict Key Processing
 
 By default, the Leader Key feature will filter the keycode out of [`Mod-Tap`](mod_tap.md) and [`Layer Tap`](feature_layers.md#switching-and-toggling-layers) functions when checking for the Leader sequences. That means if you're using `LT(3, KC_A)`, it will pick this up as `KC_A` for the sequence, rather than `LT(3, KC_A)`, giving a more expected behavior for newer users.

As an example, `rand() % (LED_DRIVER_1_LED_TOTAL + LED_DRIVER_2_LED_TOTAL)` will give very different results than `rand() % LED_DRIVER_1_LED_TOTAL + LED_DRIVER_2_LED_TOTAL`.
 
 Define these arrays listing all the LEDs in your `<keyboard>.c`:
 
 ```c
-    const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
-    /* Refer to IS31 manual for these locations
-     *    driver
-     *    |  LED address
-     *    |  | */
-        { 0, C1_1  },
-        { 0, C1_15 },
-       // ...
-    }
+const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
+/* Refer to IS31 manual for these locations
+ *    driver
+ *    |  LED address
+ *    |  | */
+    { 0, C1_1  },
+    { 0, C1_15 },
+    // ...
+}
 ```
 
 Where `Cx_y` is the location of the LED in the matrix defined by [the datasheet](https://www.issi.com/WW/pdf/31FL3731.pdf) and the header file `drivers/issi/is31fl3731-simple.h`. The `driver` is the index of the driver you defined in your `config.h` (`0`, `1`, `2`, or `3` ).

+From this point forward the configuration is the same for all the drivers. The `led_config_t` struct provides a key electrical matrix to led index lookup table, what the physical position of each LED is on the board, and what type of key or usage the LED if the LED represents. Here is a brief example:
 
+```c
+led_config_t g_led_config = { {
+  // Key Matrix to LED Index
+  {   5, NO_LED, NO_LED,   0 },
+  { NO_LED, NO_LED, NO_LED, NO_LED },
+  {   4, NO_LED, NO_LED,   1 },
+  {   3, NO_LED, NO_LED,   2 }
+}, {
+  // LED Index to Physical Position
+  { 188,  16 }, { 187,  48 }, { 149,  64 }, { 112,  64 }, {  37,  48 }, {  38,  16 }
+}, {
+  // LED Index to Flag
+  1, 4, 4, 4, 4, 1
+} };
+```
+
+The first part, `// Key Matrix to LED Index`, tells the system what key this LED represents by using the key's electrical matrix row & col. The second part, `// LED Index to Physical Position` represents the LED's physical `{ x, y }` position on the keyboard. The default expected range of values for `{ x, y }` is the inclusive range `{ 0..224, 0..64 }`. This default expected range is due to effects that calculate the center of the keyboard for their animations. The easiest way to calculate these positions is imagine your keyboard is a grid, and the top left of the keyboard represents `{ x, y }` coordinate `{ 0, 0 }` and the bottom right of your keyboard represents `{ 224, 64 }`. Using this as a basis, you can use the following formula to calculate the physical position:
+
+```c
+x = 224 / (NUMBER_OF_COLS - 1) * COL_POSITION
+y =  64 / (NUMBER_OF_ROWS - 1) * ROW_POSITION
+```
+
+Where NUMBER_OF_COLS, NUMBER_OF_ROWS, COL_POSITION, & ROW_POSITION are all based on the physical layout of your keyboard, not the electrical layout. 
+
+As mentioned earlier, the center of the keyboard by default is expected to be `{ 112, 32 }`, but this can be changed if you want to more accurately calculate the LED's physical `{ x, y }` positions. Keyboard designers can implement `#define LED_MATRIX_CENTER { 112, 32 }` in their config.h file with the new center point of the keyboard, or where they want it to be allowing more possibilities for the `{ x, y }` values. Do note that the maximum value for x or y is 255, and the recommended maximum is 224 as this gives animations runoff room before they reset.
+
+`// LED Index to Flag` is a bitmask, whether or not a certain LEDs is of a certain type. It is recommended that LEDs are set to only 1 type.

+## Custom LED Matrix Effects :id=custom-led-matrix-effects
+
+By setting `LED_MATRIX_CUSTOM_USER` (and/or `LED_MATRIX_CUSTOM_KB`) in `rules.mk`, new effects can be defined directly from userspace, without having to edit any QMK core files.
+
+To declare new effects, create a new `led_matrix_user/kb.inc` that looks something like this:
+
+`led_matrix_user.inc` should go in the root of the keymap directory.
+`led_matrix_kb.inc` should go in the root of the keyboard directory.
+
+To use custom effects in your code, simply prepend `LED_MATRIX_CUSTOM_` to the effect name specified in `LED_MATRIX_EFFECT()`. For example, an effect declared as `LED_MATRIX_EFFECT(my_cool_effect)` would be referenced with:
+
+```c
+led_matrix_mode(led_MATRIX_CUSTOM_my_cool_effect);
+```
+
+```c
+// !!! DO NOT ADD #pragma once !!! //
+
+// Step 1.
+// Declare custom effects using the LED_MATRIX_EFFECT macro
+// (note the lack of semicolon after the macro!)
+LED_MATRIX_EFFECT(my_cool_effect)
+LED_MATRIX_EFFECT(my_cool_effect2)
+
+// Step 2.
+// Define effects inside the `LED_MATRIX_CUSTOM_EFFECT_IMPLS` ifdef block
+#ifdef LED_MATRIX_CUSTOM_EFFECT_IMPLS
+
+// e.g: A simple effect, self-contained within a single method
+static bool my_cool_effect(effect_params_t* params) {
+  LED_MATRIX_USE_LIMITS(led_min, led_max);
+  for (uint8_t i = led_min; i < led_max; i++) {
+    led_matrix_set_value(i, 0xFF);
+  }
+  return led_max < DRIVER_LED_TOTAL;
+}
+
+// e.g: A more complex effect, relying on external methods and state, with
+// dedicated init and run methods
+static uint8_t some_global_state;
+static void my_cool_effect2_complex_init(effect_params_t* params) {
+  some_global_state = 1;
+}
+static bool my_cool_effect2_complex_run(effect_params_t* params) {
+  LED_MATRIX_USE_LIMITS(led_min, led_max);
+  for (uint8_t i = led_min; i < led_max; i++) {
+    led_matrix_set_value(i, some_global_state++);
+  }
+
+  return led_max < DRIVER_LED_TOTAL;
+}
+static bool my_cool_effect2(effect_params_t* params) {
+  if (params->init) my_cool_effect2_complex_init(params);
+  return my_cool_effect2_complex_run(params);
+}
+
+#endif // LED_MATRIX_CUSTOM_EFFECT_IMPLS

+## Callbacks :id=callbacks
+
+### Indicators :id=indicators
+
+If you want to set custom indicators, such as an LED for Caps Lock, or layer indication, you can use the `led_matrix_indicators_kb` or `led_matrix_indicators_user` function for that: 
 ```c
 void led_matrix_indicators_kb(void) {
-    led_matrix_set_index_value(index, value);
+    led_matrix_set_color(index, value);
 }
 ```
 
-A similar function works in the keymap as `led_matrix_indicators_user`.
+In addition, there are the advanced indicator functions.  These are aimed at those with heavily customized displays, where rendering every LED per cycle is expensive.  This includes a special macro to help make this easier to use: `LED_MATRIX_INDICATOR_SET_VALUE(i, v)`.
 
-## Suspended State
+```c
+void led_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
+    LED_MATRIX_INDICATOR_SET_VALUE(index, value);
+}
+```
 
-To use the suspend feature, add this to your `<keyboard>.c`:
+## Suspended State :id=suspended-state
+To use the suspend feature, make sure that `#define LED_DISABLE_WHEN_USB_SUSPENDED true` is added to the `config.h` file. 
+
+Additionally add this to your `<keyboard>.c`:
 
 ```c
 void suspend_power_down_kb(void) {
     led_matrix_set_suspend_state(true);
+    suspend_power_down_user();
 }
 
 void suspend_wakeup_init_kb(void) {
     led_matrix_set_suspend_state(false);
+    suspend_wakeup_init_user();
 }
-```
+```
+or add this to your `keymap.c`:
+```c
+void suspend_power_down_user(void) {
+    led_matrix_set_suspend_state(true);
+}
+
+void suspend_wakeup_init_user(void) {
+    led_matrix_set_suspend_state(false);
+}
+```

+# MIDI
+
+## Usage
+
+First, enable MIDI by adding the following to your `rules.mk`:
+
+```makefile
+MIDI_ENABLE = yes
+```
+
+There are two MIDI systems in QMK: basic and advanced. With basic MIDI you will only be able to send Note On and Note Off messages using the note keycodes, meaning that keycodes like `MI_OCTU` and `MI_OCTD` will not work. Advanced MIDI allows you to do things like octave shifts, channel changes, velocity changes, modulation, and more.
+
+### Basic MIDI
+
+To enable basic MIDI, add the following to your `config.h`:
+
+```c
+#define MIDI_BASIC
+```
+
+### Advanced MIDI
+
+To enable advanced MIDI, add the following to your `config.h`:
+
+```c
+#define MIDI_ADVANCED
+```
+
+#### Sending Control Change (CC) Messages
+
+If you're aiming to emulate the features of something like a Launchpad or other MIDI controller you'll need to access the internal MIDI device directly.
+
+Because there are so many possible CC messages, not all of them are implemented as keycodes. Additionally, you might need to provide more than just two values that you would get from a keycode (pressed and released) - for example, the analog values from a fader or a potentiometer. So, you will need to implement [custom keycodes](feature_macros.md) if you want to use them in your keymap directly using `process_record_user()`.

+For reference of all the possible control code numbers see [MIDI Specification](#midi-specification)

+enum custom_keycodes {

+bool process_record_user(uint16_t keycode, keyrecord_t *record) {

+### Configuration
+
+Certain values are stored in the `midi_config` struct. This configuration is not persisted to EEPROM. By default, these values are:
+
+|Configuration      |Value|Comments                 |
+|-------------------|-----|-------------------------|
+|Octave             |`4`  |Corresponds to `MI_OCT_2`|
+|Transposition      |`0`  |                         |
+|Velocity           |`127`|                         |
+|Channel            |`0`  |                         |
+|Modulation Interval|`8`  |                         |
+
+For the above, the `MI_C` keycode will produce a C3 (note number 48), and so on.

+Note that the total resistance for the connected system should be within spec at 2.2k-10kOhm, with an 'ideal' at 4.7kOhm, regardless of the placement and number.

+
+### Custom data sync between sides :id=custom-data-sync
+
+QMK's split transport allows for arbitrary data transactions at both the keyboard and user levels. This is modelled on a remote procedure call, with the master invoking a function on the slave side, with the ability to send data from master to slave, process it slave side, and send data back from slave to master.
+
+To leverage this, a keyboard or user/keymap can define a comma-separated list of _transaction IDs_:
+
+```c
+// for keyboard-level data sync:
+#define SPLIT_TRANSACTION_IDS_KB KEYBOARD_SYNC_A, KEYBOARD_SYNC_B
+// or, for user:
+#define SPLIT_TRANSACTION_IDS_USER USER_SYNC_A, USER_SYNC_B, USER_SYNC_C
+```
+
+These _transaction IDs_ then need a slave-side handler function to be registered with the split transport, for example:
+
+```c
+typedef struct _master_to_slave_t {
+    int m2s_data;
+} master_to_slave_t;
+
+typedef struct _slave_to_master_t {
+    int s2m_data;
+} slave_to_master_t;
+
+void user_sync_a_slave_handler(uint8_t in_buflen, const void* in_data, uint8_t out_buflen, void* out_data) {
+    const master_to_slave_t *m2s = (const master_to_slave_t*)in_data;
+    slave_to_master_t *s2m = (slave_to_master_t*)out_data;
+    s2m->s2m_data = m2s->m2s_data + 5; // whatever comes in, add 5 so it can be sent back
+}
+
+void keyboard_post_init_user(void) {
+    transaction_register_rpc(USER_SYNC_A, user_sync_a_slave_handler);
+}
+```
+
+The master side can then invoke the slave-side handler - for normal keyboard functionality to be minimally affected, any keyboard- or user-level code attempting to sync data should be throttled:
+
+```c
+void housekeeping_task_user(void) {
+    if (is_keyboard_master()) {
+        // Interact with slave every 500ms
+        static uint32_t last_sync = 0;
+        if (timer_elapsed32(last_sync) > 500) {
+            master_to_slave_t m2s = {6};
+            slave_to_master_t s2m = {0};
+            if(transaction_rpc_exec(USER_SYNC_A, sizeof(m2s), &m2s, sizeof(s2m), &s2m)) {
+                last_sync = timer_read32();
+                dprintf("Slave value: %d\n", s2m.s2m_data); // this will now be 11, as the slave adds 5
+            } else {
+                dprint("Slave sync failed!\n");
+            }
+        }
+    }
+}
+```
+
+!> It is recommended that any data sync between halves happens during the master side's _housekeeping task_. This ensures timely retries should failures occur.
+
+If only one-way data transfer is needed, helper methods are provided:
+
+```c
+bool transaction_rpc_exec(int8_t transaction_id, uint8_t initiator2target_buffer_size, const void *initiator2target_buffer, uint8_t target2initiator_buffer_size, void *target2initiator_buffer);
+bool transaction_rpc_send(int8_t transaction_id, uint8_t initiator2target_buffer_size, const void *initiator2target_buffer);
+bool transaction_rpc_recv(int8_t transaction_id, uint8_t target2initiator_buffer_size, void *target2initiator_buffer);
+```
+
+By default, the inbound and outbound data is limited to a maximum of 32 bytes each. The sizes can be altered if required:
+
+```c
+// Master to slave:
+#define RPC_M2S_BUFFER_SIZE 48
+// Slave to master:
+#define RPC_S2M_BUFFER_SIZE 48

+
+## Usage
+
+To enable the feature, there are three steps. First, when compiling your keyboard, you'll need to add the following to your `rules.mk`:
+
+```make
+ST7565_ENABLE = yes
+```
+
+Then in your `keymap.c` file, implement the ST7565 task call. This example assumes your keymap has three layers named `_QWERTY`, `_FN` and `_ADJ`:
+
+```c
+#ifdef ST7565_ENABLE
+void st7565_task_user(void) {
+    // Host Keyboard Layer Status
+    st7565_write_P(PSTR("Layer: "), false);
+
+    switch (get_highest_layer(layer_state)) {
+        case _QWERTY:
+            st7565_write_P(PSTR("Default\n"), false);
+            break;
+        case _FN:
+            st7565_write_P(PSTR("FN\n"), false);
+            break;
+        case _ADJ:
+            st7565_write_P(PSTR("ADJ\n"), false);
+            break;
+        default:
+            // Or use the write_ln shortcut over adding '\n' to the end of your string
+            st7565_write_ln_P(PSTR("Undefined"), false);
+    }
+
+    // Host Keyboard LED Status
+    led_t led_state = host_keyboard_led_state();
+    st7565_write_P(led_state.num_lock ? PSTR("NUM ") : PSTR("    "), false);
+    st7565_write_P(led_state.caps_lock ? PSTR("CAP ") : PSTR("    "), false);
+    st7565_write_P(led_state.scroll_lock ? PSTR("SCR ") : PSTR("    "), false);
+}
+#endif
+```
+
+## Logo Example
+
+In the default font, certain ranges of characters are reserved for a QMK logo. To render this logo to the screen, use the following code example:
+
+```c
+static void render_logo(void) {
+    static const char PROGMEM qmk_logo[] = {
+        0x80, 0x81, 0x82, 0x83, 0x84, 0x85, 0x86, 0x87, 0x88, 0x89, 0x8A, 0x8B, 0x8C, 0x8D, 0x8E, 0x8F, 0x90, 0x91, 0x92, 0x93, 0x94,
+        0xA0, 0xA1, 0xA2, 0xA3, 0xA4, 0xA5, 0xA6, 0xA7, 0xA8, 0xA9, 0xAA, 0xAB, 0xAC, 0xAD, 0xAE, 0xAF, 0xB0, 0xB1, 0xB2, 0xB3, 0xB4,
+        0xC0, 0xC1, 0xC2, 0xC3, 0xC4, 0xC5, 0xC6, 0xC7, 0xC8, 0xC9, 0xCA, 0xCB, 0xCC, 0xCD, 0xCE, 0xCF, 0xD0, 0xD1, 0xD2, 0xD3, 0xD4, 0x00
+    };
+
+    st7565_write_P(qmk_logo, false);
+}
+```
+
+## Buffer Read Example
+For some purposes, you may need to read the current state of the display buffer. The `st7565_read_raw` function can be used to safely read bytes from the buffer.
+
+In this example, calling `fade_display` in the `st7565_task_user` function will slowly fade away whatever is on the screen by turning random pixels off over time.
+```c
+//Setup some mask which can be or'd with bytes to turn off pixels
+const uint8_t single_bit_masks[8] = {127, 191, 223, 239, 247, 251, 253, 254};
+
+static void fade_display(void) {
+    //Define the reader structure
+    display_buffer_reader_t reader;
+    uint8_t buff_char;
+    if (random() % 30 == 0) {
+        srand(timer_read());
+        // Fetch a pointer for the buffer byte at index 0. The return structure
+        // will have the pointer and the number of bytes remaining from this
+        // index position if we want to perform a sequential read by
+        // incrementing the buffer pointer
+        reader = st7565_read_raw(0);
+        //Loop over the remaining buffer and erase pixels as we go
+        for (uint16_t i = 0; i < reader.remaining_element_count; i++) {
+            //Get the actual byte in the buffer by dereferencing the pointer
+            buff_char = *reader.current_element;
+            if (buff_char != 0) {
+                st7565_write_raw_byte(buff_char & single_bit_masks[rand() % 8], i);
+            }
+            //increment the pointer to fetch a new byte during the next loop
+            reader.current_element++;
+        }
+    }
+}
+```
+
+## Other Examples
+
+In split keyboards, it is very common to have two displays that each render different content and are oriented or flipped differently. You can do this by switching which content to render by using the return value from `is_keyboard_master()` or `is_keyboard_left()` found in `split_util.h`, e.g:
+
+```c
+#ifdef ST7565_ENABLE
+display_rotation_t st7565_init_user(display_rotation_t rotation) {
+    if (!is_keyboard_master()) {
+        return DISPLAY_ROTATION_180;  // flips the display 180 degrees if offhand
+    }
+
+    return rotation;
+}
+
+void st7565_task_user(void) {
+    if (is_keyboard_master()) {
+        render_status();  // Renders the current keyboard state (layer, lock, caps, scroll, etc)
+    } else {
+        render_logo();  // Renders a static logo
+    }
+}
+#endif
+```

+-->
+
+このページでは、QMK のデータ駆動型 JSON コンフィギュレーションシステムがどのように動作するかを説明します。これは、QMK 自体に取り組みたい開発者を対象としています。
+
+## ヒストリー
+
+これまで、QMK は、`rules.mk` と `config.h` の2つのメカニズムを組み合わせてコンフィギュレーションされてきました。
+この方法は、QMK がほんの一握りのキーボードをサポートしていたときは上手く機能していましたが、今では、サポートするキーボードは1500近くまで成長しました。
+`keyboards` の下だけで6000個の設定ファイルがあることが推定されます。
+これらのファイルの自由形式の性質と、重複を避けるために人々が使用してきたユニークなパターンが継続的なメンテナンスを困難にしており、また、多くのキーボードが時代遅れで時には理解が難しいパターンに従っています。
+
+また、CLI に慣れていない人に QMK のパワーを提供することにも取り組んでおり、VIA などの他のプロジェクトでは、プログラムをインストールするのと同じくらい簡単に QMK を使用できるように取り組んでいます。
+これらのツールには、ユーザーが QMK を最大限に活用できるように、キーボードのレイアウト方法や使用可能なピンと機能に関する情報が必要です。
+その第一歩として `info.json` を導入しました。
+QMK API は、これら3つの情報源（`config.h`、` rules.mk`、および `info.json`）を、エンドユーザーツールが使用できる信頼できる単一の情報源に結合するための取り組みです。
+
+これで、`info.json`から `rules.mk` と `config.h` の値を生成することがサポートされ、信頼できる単一の情報源を持つことができます。
+これにより、自動化されたツールを使用してキーボードを保守できるため、時間と保守作業を大幅に節約できます。
+
+## 概要
+
+C 側では何も変わりません。
+新しいルールを作成したり、定義したりする必要がある場合は、同じプロセスに従います。
+
+1. `docs/config_options.md` に追加します。
+1. 適切なコアファイルにデフォルトを設定します。
+1. 必要に応じて ifdef 文を追加します。
+
+次に、新しい構成のサポートを `info.json` に追加する必要があります。
+基本的なプロセスは次のとおりです。
+
+1. `data/schemas/keyboards.jsonschema` のスキーマに追加します
+1. `data/maps` にマッピングを追加します
+1. （オプションおよび非推奨）構成を抽出/生成するコードを追加します。
+   * `lib/python/qmk/info.py`
+   * `lib/python/qmk/cli/generate/config_h.py`
+   * `lib/python/qmk/cli/generate/rules_mk.py`
+
+## info.json にオプションを追加する
+
+このセクションでは、info.json に `config.h`/`rules.mk` の値のサポートを追加することについて説明します。
+
+### スキーマに追加する
+
+QMK では、[jsonschema](https:json-schema.org) のファイルを `data/schemas` に保持しています。
+キーボード固有の `info.json` ファイルに入る値は `keyboard.jsonschema` に保持されています。
+エンドユーザーが編集できるようにしたい値はすべてここに入れなければなりません。
+
+場合によっては、新しいトップレベルキーを追加するだけで済みます。
+従うべきいくつかの例は、 `keyboard_name`、`maintainer`、 `processor`、および `url` です。
+これは、オプションが自己完結型で、他のオプションと直接関係がない場合に適しています。
+
+その他の場合、1つの `object` の中に、似ているオプションを集める必要があります。
+これは、機能のサポートを追加する場合に特に当てはまります。
+このために従うべきいくつかの例は、`indicators`、`matrix_pins`、および `rgblight` です。
+新しいオプションを統合する方法がわからない場合は、[問題を開く](https://github.com/qmk/qmk_firmware/issues/new?assignees=&labels=cli%2C+python&template=other_issues.md&title=)か、[Discord で #cli に参加](https://discord.gg/heQPAgy)して、そこで会話を始めてください。
+
+### マッピングを追加する
+
+ほとんどの場合、単純なマッピングを追加することができます。
+これらは `data/mappings/info_config.json` と `data/mappings/info_rules.json` に JSON ファイルとして保持され、それぞれ `config.h` と `rules.mk` のマッピングを制御します。
+各マッピングは `config.h` または `rules.mk` 変数名をキーとし、値は以下のキーを持つハッシュです。
+
+* `info_key`: (必須）この値の `info.json` 内の場所。 下記参照。
+* `value_type`: (オプション）デフォルトは `str`。 この変数の値の形式。 下記参照。
+* `to_json`: (オプション）デフォルトは `true`。 このマッピングを info.json から除外するには、`false` に設定します
+* `to_c`: (オプション）デフォルトは `true`。 このマッピングを config.h から除外するには、`false` に設定します
+* `warn_duplicate`: (オプション）デフォルトは `true`。 値が両方の場所に存在する場合に警告をオフにするには、`false` に設定します
+
+#### Info Key
+
+info.json 内の変数をアドレス指定するために JSON ドット表記を使用します。
+たとえば、`info_json["rgblight"]["split_count"]` にアクセスするには、`rgblight.split_count` を指定します。
+これにより、深くネストされたキーを単純な文字列でアドレス指定できます。
+
+内部では [Dotty Dict](https://dotty-dict.readthedocs.io/en/latest/) を使用しています。これらの文字列がオブジェクトアクセスに変換される方法についてはそのドキュメントを参照してください。
+
+#### Value Types
+
+デフォルトでは、すべての値を単純な文字列として扱います。
+値がより複雑な場合は、次のいずれかのタイプを使用してデータをインテリジェントに解析できます。
+
+* `array`: 文字列のコンマ区切りの配列
+* `array.int`: 整数のコンマ区切り配列
+* `int`: 整数
+* `hex`: 16進数としてフォーマットされた数値
+* `list`: 文字列のスペース区切りの配列
+* `mapping`: キーと値のペアのハッシュ
+
+### 抽出するコードを追加する
+
+ほとんどのユースケースは、上記のマッピングファイルによって解決できます。
+できない場合は、代わりに設定値を抽出するコードを書くことができます。
+
+QMK が完全な `info.json` を生成するときはいつでも、`config.h` と `rules.mk` から情報を抽出します。
+あなたの新しい設定値のためのコードを `lib/python/qmk/info.py` に追加する必要があります。
+通常、これは、新しい `_extract_<feature>()` 関数を追加してから、 `_extract_config_h()` または `_extract_rules_mk()` のいずれかで関数を呼び出すことを意味します。
+
+このファイルの編集方法がわからない場合、または Python に慣れていない場合は、[issue を開く](https://github.com/qmk/qmk_firmware/issues/new?assignees=&labels=cli%2C+python&template=other_issues.md&title=）か [Discord で #cli に参加](https://discord.gg/heQPAgy)すると、この部分を誰かが手伝ってくれるでしょう。
+
+### 生成するコードを追加する
+
+パズルの最後のピースは、ビルドシステムに新しいオプションを提供することです。
+これは、2つのファイルを生成することによって行われます。
+
+* `.build/obj_<keyboard>/src/info_config.h`
+* `.build/obj_<keyboard>/src/rules.mk`
+
+この2つのファイルは、次のコードによって生成されます。
+
+* `lib/python/qmk/cli/generate/config_h.py`
+* `lib/python/qmk/cli/generate/rules_mk.py`
+
+`config.h`値の場合、ルール用の関数を記述し、その関数を `generate_config_h()` で呼び出す必要があります。
+
+`rules.mk` の新しいトップレベルの `info.json` キーがある場合は、`lib/python/qmk/cli/generate/rules_mk.py` の上部にある `info_to_rules` にキーを追加するだけです。
+それ以外の場合は、`generate_rules_mk()` で機能の新しい if ブロックを作成する必要があります。

-現在のところ、`LT()` と `MT()` は[基本的なキーコードセット](ja/keycodes_basic.md)に制限されています。つまり、`LCTL()`、`KC_TILD` あるいは `0xFF` より大きなキーコードを使うことができません。特に、`LT` と `MT` のような二重の機能キーは16ビットキーコードを使います。4ビットは機能の識別のために使われ、次の12ビットはパラメータに分かれます。レイヤータップはレイヤーに4ビットを使います(実はレイヤータップがレイヤー 0-15 に制限されている理由です)。モッドタップも同じですが、識別子に4ビット、モッドのために4ビットが使われ、全体でキーコードに8ビットを使います。このため、使用されるキーコードは `0xFF` (0-255) に制限され、基本的なキーコードのみです。

 これを拡張してもせいぜい複雑になるだけでしょう。32ビットキーコードに移行すると、これの多くが解決されますが、キーマップマトリックスが使用する領域が2倍になります。また、問題が起きる可能性もあります。タップしたキーコードにモディファイアを適用する必要がある場合は、[タップダンス](ja/feature_tap_dance.md#example-5-using-tap-dance-for-advanced-mod-tap-and-layer-tap-keys)を使うことができます。

+
+### 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, but it is more efficent as it uses DMA transfers, which can result in even faster transmission speeds.
+
+#### Pin configuration
+
+`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.
+
+#### 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.
+
+#### Setup
+To use the driver, add this to your rules.mk:
+
+```make
+SERIAL_DRIVER = usart_duplex
+```
+
+Next configure the hardware via your config.h:
+
+```c
