RGB Matrix Lighting :id=rgb-matrix-lighting
This feature allows you to use RGB LED matrices driven by external drivers. It hooks into the RGBLIGHT system so you can use the same keycodes as RGBLIGHT to control it.
If you want to use single color LED's you should use the LED Matrix Subsystem instead.

Common Configuration :id=common-configuration
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:
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:
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 RGB_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.
Flags :id=flags
| Define | Value | Description |

RGB_MODE_PLAIN |
RGB_M_P |
Static (no animation) mode |
RGB_MODE_BREATHE |
RGB_M_B |

RGB_MODE_*keycodes will generally work, but not all of the modes are currently mapped to the correct effects for the RGB Matrix system.
RGB_MODE_PLAIN, RGB_MODE_BREATHE, RGB_MODE_RAINBOW, and RGB_MATRIX_SWIRL are the only ones that are mapped properly. The rest don't have a direct equivalent, and are not mapped.
!> By default, if you have both the RGB Light and the RGB Matrix feature enabled, these keycodes will work for both features, at the same time. You can disable the keycode functionality by defining the *_DISABLE_KEYCODES option for the specific feature.

RGB Matrix Effect Typing Heatmap :id=rgb-matrix-effect-typing-heatmap
This effect will color the RGB matrix according to a heatmap of recently pressed keys. Whenever a key is pressed its "temperature" increases as well as that of its neighboring keys. The temperature of each key is then decreased automatically every 25 milliseconds by default.
In order to change the delay of temperature decrease define
RGB_MATRIX_TYPING_HEATMAP_DECREASE_DELAY_MS:
#define RGB_MATRIX_TYPING_HEATMAP_DECREASE_DELAY_MS 50
Custom RGB Matrix Effects :id=custom-rgb-matrix-effects
By setting RGB_MATRIX_CUSTOM_USER (and/or RGB_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 rgb_matrix_user/kb.inc that looks something like this:
rgb_matrix_user.inc should go in the root of the keymap directory.
rgb_matrix_kb.inc should go in the root of the keyboard directory.
To use custom effects in your code, simply prepend RGB_MATRIX_CUSTOM_ to the effect name specified in RGB_MATRIX_EFFECT(). For example, an effect declared as RGB_MATRIX_EFFECT(my_cool_effect) would be referenced with:
rgb_matrix_mode(RGB_MATRIX_CUSTOM_my_cool_effect);
// !!! DO NOT ADD #pragma once !!! //
// Step 1.
// Declare custom effects using the RGB_MATRIX_EFFECT macro
// (note the lack of semicolon after the macro!)
RGB_MATRIX_EFFECT(my_cool_effect)
RGB_MATRIX_EFFECT(my_cool_effect2)
// Step 2.
// Define effects inside the `RGB_MATRIX_CUSTOM_EFFECT_IMPLS` ifdef block
#ifdef RGB_MATRIX_CUSTOM_EFFECT_IMPLS
// e.g: A simple effect, self-contained within a single method
static bool my_cool_effect(effect_params_t* params) {
RGB_MATRIX_USE_LIMITS(led_min, led_max);
for (uint8_t i = led_min; i < led_max; i++) {
rgb_matrix_set_color(i, 0xff, 0xff, 0x00);
}
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) {
RGB_MATRIX_USE_LIMITS(led_min, led_max);
for (uint8_t i = led_min; i < led_max; i++) {
rgb_matrix_set_color(i, 0xff, some_global_state++, 0xff);
}
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 // RGB_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 rgb_matrix_indicators_kb or rgb_matrix_indicators_user function for that:
void rgb_matrix_indicators_kb(void) {
rgb_matrix_set_color(index, red, green, blue);
}
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. Such as some of the "drashna" layouts. This includes a special macro to help make this easier to use: RGB_MATRIX_INDICATOR_SET_COLOR(i, r, g, b).
void rgb_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
RGB_MATRIX_INDICATOR_SET_COLOR(index, red, green, blue);
}
Indicator Examples :id=indicator-examples
Caps Lock indicator on alphanumeric flagged keys:
void rgb_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
if (host_keyboard_led_state().caps_lock) {
for (uint8_t i = led_min; i <= led_max; i++) {
if (g_led_config.flags[i] & LED_FLAG_KEYLIGHT) {
rgb_matrix_set_color(i, RGB_RED);
}
}
}
}
Layer indicator on all flagged keys:
void rgb_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
for (uint8_t i = led_min; i <= led_max; i++) {
switch(get_highest_layer(layer_state|default_layer_state)) {
case RAISE:
rgb_matrix_set_color(i, RGB_BLUE);
break;
case LOWER:
rgb_matrix_set_color(i, RGB_YELLOW);
break;
default:
break;
}
}
}
Examples :id=indicator-examples
This example sets the modifiers to be a specific color based on the layer state. You can use a switch case here, instead, if you would like. This uses HSV and then converts to RGB, because this allows the brightness to be limited (important when using the WS2812 driver).
void rgb_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
HSV hsv = {0, 255, 255};
if (layer_state_is(layer_state, 2)) {
hsv = {130, 255, 255};
} else {
hsv = {30, 255, 255};
}
if (hsv.v > rgb_matrix_get_val()) {
hsv.v = rgb_matrix_get_val();
}
RGB rgb = hsv_to_rgb(hsv);
for (uint8_t i = led_min; i <= led_max; i++) {
if (HAS_FLAGS(g_led_config.flags[i], 0x01)) { // 0x01 == LED_FLAG_MODIFIER
rgb_matrix_set_color(i, rgb.r, rgb.g, rgb.b);
}
}
}
If you want to indicate a Host LED status (caps lock, num lock, etc), you can use something like this to light up the caps lock key:
void rgb_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
if (host_keyboard_led_state().caps_lock) {
RGB_MATRIX_INDICATOR_SET_COLOR(5, 255, 255, 255); // assuming caps lock is at led #5
} else {
RGB_MATRIX_INDICATOR_SET_COLOR(5, 0, 0, 0);
}
}
