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.
There is basic support for addressable RGB matrix lighting with the I2C IS31FL3731 RGB controller. To enable it, add this to your rules.mk
:
RGB_MATRIX_ENABLE = yes
RGB_MATRIX_DRIVER = IS31FL3731
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
:
Variable | Description | Default |
---|---|---|
ISSI_TIMEOUT |
(Optional) How long to wait for i2c messages, in milliseconds | 100 |
ISSI_PERSISTENCE |
(Optional) Retry failed messages this many times | 0 |
ISSI_3731_DEGHOST |
(Optional) Set this define to enable de-ghosting by halving Vcc during blanking time | |
DRIVER_COUNT |
(Required) How many RGB driver IC's are present | |
DRIVER_LED_TOTAL |
(Required) How many RGB lights are present across all drivers | |

is used in code and expanded, the values are added together before any additional math is applied to them. As an example, rand() % (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)
will give very different results than rand() % DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL
.
For split keyboards using RGB_MATRIX_SPLIT
with an LED driver, you can either have the same driver address or different driver addresses. If using different addresses, use DRIVER_ADDR_1
for one and DRIVER_ADDR_2
for the other one. Then, in g_is31_leds
, fill out the correct driver index (0 or 1). If using one address, use DRIVER_ADDR_1
for both, and use index 0 for g_is31_leds
.
Define these arrays listing all the LEDs in your <keyboard>.c
:

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.

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
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 rgb_matrix_check_finished_leds(led_max);
}
// 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 rgb_matrix_check_finished_leds(led_max);
}
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);

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);
}
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;
}
}
}
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);
}
}
If you want to just use RGB indicators without RGB matrix effect, it is not possible to disable the latter because toggling RGB off will disable everything. You can workaround it with solid effect and colors off using this init function:
void keyboard_post_init_user(void) {
rgb_matrix_mode_noeeprom(RGB_MATRIX_SOLID_COLOR);
rgb_matrix_sethsv_noeeprom(HSV_OFF);
}
