+## Bootmagic Deprecation and Refactor ([#12172](https://github.com/qmk/qmk_firmware/pull/12172))
+
+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.
+
+### Tentative Deprecation Schedule
+
+This is the current planned roadmap for the behavior of `BOOTMAGIC_ENABLE`:
+
+- From 2021-05-29, setting `BOOTMAGIC_ENABLE = yes` will enable Bootmagic Lite instead of full Bootmagic.
+- From 2021-08-28, `BOOTMAGIC_ENABLE` must be either `yes`, `lite`, or `no` – setting `BOOTMAGIC_ENABLE = full` will cause compilation to fail.
+- From 2021-11-27, `BOOTMAGIC_ENABLE` must be either `yes` or `no` – setting `BOOTMAGIC_ENABLE = lite` will cause compilation to fail.

+## 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.

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` ).
-## 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:
+
+```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

-## 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)`.
+
+```c
+void led_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
+ LED_MATRIX_INDICATOR_SET_VALUE(index, value);
+}
+```
-## Suspended State
+## 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.
-To use the suspend feature, add this to your `<keyboard>.c`:
+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);
}

-

-This function returns the current WPM as an unsigned integer.
+## Configuration
+|Define |Default | Description |
+|-----------------------------|--------------|------------------------------------------------------------------------------------------|
+|`WPM_SMOOTHING` |`0.0487` | Sets the smoothing to about 40 keystrokes |

+|Function |Description |
+|--------------------------|--------------------------------------------------|
+|`get_current_wpm(void)` | Returns the current WPM as a value 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.
+
+For instance, the default is:
+
+```c
+bool wpm_keycode_user(uint16_t keycode) {
+ if ((keycode >= QK_MOD_TAP && keycode <= QK_MOD_TAP_MAX) || (keycode >= QK_LAYER_TAP && keycode <= QK_LAYER_TAP_MAX) || (keycode >= QK_MODS && keycode <= QK_MODS_MAX)) {

+ }
+ if ((keycode >= KC_A && keycode <= KC_0) || (keycode >= KC_TAB && keycode <= KC_SLASH)) {
+ return true;
+ }
+
+ return false;
+}
+```
+
+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
+```

+
+```c

+
+Pin Swap available: N/A
+
+TX Pin is always Alternate Function Push-Pull, RX Pin is always regular input pin for any USART peripheral. **For STM32F103 no additional Alternate Function configuration is necessary. QMK is already configured.**
+
+Pin remapping:
+
+The pins of USART Peripherals use default Pins that can be remapped to use other pins using the AFIO registers. Default pins are marked **bold**. Add the appropriate defines to your config.h file.

+#### Circular Buffer Mode
+Some boards may flicker while in the normal buffer mode. To fix this issue, circular buffer mode may be used to rectify the issue.
+
+By default, the circular buffer mode is disabled.
+
+To enable this alternative buffer mode, place this into your `config.h` file:
+```c
+#define WS2812_SPI_USE_CIRCULAR_BUFFER
+```
+
+#### Setting baudrate with divisor
+To adjust the baudrate at which the SPI peripheral is configured, users will need to derive the target baudrate from the clock tree provided by STM32CubeMX.
+
+Only divisors of 2, 4, 8, 16, 32, 64, 128 and 256 are supported by hardware.

+Note that using a complementary timer output (TIMx_CHyN) is possible only for advanced-control timers (TIM1, TIM8, TIM20 on STM32), and the `STM32_PWM_USE_ADVANCED` option in mcuconf.h must be set to `TRUE`. Complementary outputs of general-purpose timers are not supported due to ChibiOS limitations.
