### 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.
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`.
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.

## Hardware
The A an B lines of the encoders should be wired directly to the MCU, and the C/common lines should be wired to ground.
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.
This feature allows you to use LED matrices driven by external drivers. It hooks into the backlight system so you can use the same keycodes as backlighting to control it.
If you want to use RGB LED's you should use the [RGB Matrix Subsystem](feature_rgb_matrix.md) instead.

## Keycodes
---
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:
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:
#define LED_DISABLE_TIMEOUT 0 // number of milliseconds to wait until led automatically turns off
#define LED_DISABLE_AFTER_TIMEOUT 0 // OBSOLETE: number of ticks to wait until disabling effects
#define LED_DISABLE_WHEN_USB_SUSPENDED false // turn off effects when suspended
#define LED_MATRIX_LED_PROCESS_LIMIT (DRIVER_LED_TOTAL + 4) / 5 // limits the number of LEDs to process in an animation per task run (increases keyboard responsiveness)
#define LED_MATRIX_LED_FLUSH_LIMIT 16 // limits in milliseconds how frequently an animation will update the LEDs. 16 (16ms) is equivalent to limiting to 60fps (increases keyboard responsiveness)
#define LED_MATRIX_MAXIMUM_BRIGHTNESS 255 // limits maximum brightness of LEDs
#define LED_MATRIX_STARTUP_MODE LED_MATRIX_SOLID // Sets the default mode, if none has been set
#define LED_MATRIX_STARTUP_VAL LED_MATRIX_MAXIMUM_BRIGHTNESS // Sets the default brightness value, if none has been set
#define LED_MATRIX_STARTUP_SPD 127 // Sets the default animation speed, if none has been set
#define LED_MATRIX_SPLIT { X, Y } // (Optional) For split keyboards, the number of LEDs connected on each half. X = left, Y = Right.
// If LED_MATRIX_KEYPRESSES or LED_MATRIX_KEYRELEASES is enabled, you also will want to enable SPLIT_TRANSPORT_MIRROR
```
## EEPROM storage :id=eeprom-storage
The EEPROM for it is currently shared with the RGB Matrix system (it's generally assumed only one feature would be used at a time), but could be configured to use its own 32bit address with:
|`led_matrix_set_value_all(v)` |Set all of the LEDs to the given value, where `v` is between 0 and 255 (not written to EEPROM) |
|`led_matrix_set_value(index, v)` |Set a single LED to the given value, where `v` is between 0 and 255, and `index` is between 0 and `DRIVER_LED_TOTAL` (not written to EEPROM) |

## Custom Layer Effects
## Callbacks :id=callbacks
Custom layer effects can be done by defining this in your `<keyboard>.c`:
### 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)`.
You can use between 1 and 4 IS31FL3731 IC's. Do not specify `DRIVER_ADDR_<N>` defines for IC's that are not present on your keyboard. You can define the following items in `config.h`:

### Overriding RGB Lighting on/off status
Normally lighting layers are not shown when RGB Lighting is disabled (e.g. with `RGB_TOG` keycode). If you would like lighting layers to work even when the RGB Lighting is otherwise off, add `#define RGBLIGHT_LAYERS_OVERRIDE_RGB_OFF` to your `config.h`.
Example uses include sending Unicode strings when a key is pressed, as described in [Macros](feature_macros.md).
### `send_unicode_hex_string()`
### `send_unicode_hex_string()` (Deprecated)
Similar to `send_unicode_string()`, but the characters are represented by their Unicode code points, written in hexadecimal and separated by spaces. For example, the table flip above would be achieved with:
|`get_current_wpm(void)` | Returns the current WPM as a value between 0-255 |
|`set_current_wpm(x)` | Sets the current WPM to `x` (between 0-255) |
## Callbacks
By default, the WPM score only includes letters, numbers, space and some punctuation. If you want to change the set of characters considered as part of the WPM calculation, you can implement your own `bool wpm_keycode_user(uint16_t keycode)` and return true for any characters you would like included in the calculation, or false to not count that particular keycode.
Additionally, if `WPM_ALLOW_COUNT_REGRESSION` is defined, there is the `uint8_t wpm_regress_count(uint16_t keycode)` function that allows you to decrease the WPM. This is useful if you want to be able to penalize certain keycodes (or even combinations).

### 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
```
