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.

Driver configuration :id=driver-configuration

IS31FL3731 :id=is31fl3731

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
`IS31FL3731_I2C_TIMEOUT`	(Optional) How long to wait for i2c messages, in milliseconds	100
`IS31FL3731_I2C_PERSISTENCE`	(Optional) Retry failed messages this many times	0
`IS31FL3731_DEGHOST`	(Optional) Set this define to enable de-ghosting by halving Vcc during blanking time
`IS31FL3731_DRIVER_COUNT`	(Required) How many RGB driver IC's are present
`RGB_MATRIX_LED_COUNT`	(Required) How many RGB lights are present across all drivers
`DRIVER_ADDR_1`	(Required) Address for the first RGB driver
`DRIVER_ADDR_2`	(Optional) Address for the second RGB driver
`DRIVER_ADDR_3`	(Optional) Address for the third RGB driver
`DRIVER_ADDR_4`	(Optional) Address for the fourth RGB driver

Here is an example using 2 drivers.

// This is a 7-bit address, that gets left-shifted and bit 0
// set to 0 for write, 1 for read (as per I2C protocol)
// The address will vary depending on your wiring:
// 00 AD <-> GND
// 01 AD <-> SCL
// 10 AD <-> SDA
// 11 AD <-> VCC
// ADDR represents A1:A0 of the 7-bit address.
// The result is: 0b11101(ADDR)
#define DRIVER_ADDR_1 IS31FL3731_I2C_ADDRESS_GND
#define DRIVER_ADDR_2 IS31FL3731_I2C_ADDRESS_SDA

#define IS31FL3731_DRIVER_COUNT 2
#define DRIVER_1_LED_TOTAL 25
#define DRIVER_2_LED_TOTAL 24
#define RGB_MATRIX_LED_COUNT (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)

!> Note the parentheses, this is so when RGB_MATRIX_LED_COUNT 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_is31fl3731_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_is31fl3731_leds.

Define these arrays listing all the LEDs in your <keyboard>.c:

const is31fl3731_led_t PROGMEM g_is31fl3731_leds[RGB_MATRIX_LED_COUNT] = {
/* Refer to IS31 manual for these locations
 *   driver
 *   |  R location
 *   |  |      G location
 *   |  |      |      B location
 *   |  |      |      | */
    {0, C1_3,  C2_3,  C3_3},
    ....
}

Where Cx_y is the location of the LED in the matrix defined by the datasheet and the header file drivers/led/issi/is31fl3731.h. The driver is the index of the driver you defined in your config.h (0, 1, 2, or 3).

You can use between 1 and 4 IC's. Do not specify DRIVER_ADDR_<N> define for IC's if not present on your keyboard. The DRIVER_ADDR_1 default assumes that all Address pins on the controller have been connected to GND. Drivers that have SYNC functionality have the default settings to disable if 1 driver.

#define RGB_MATRIX_LED_COUNT (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)

Currently only 4 drivers are supported, but it would be trivial to support for more. Note that using a combination of different drivers is not supported. All drivers must be of the same model.

Define these arrays listing all the LEDs in your <keyboard>.c:

const is31_led PROGMEM g_is31_leds[RGB_MATRIX_LED_COUNT] = {
/* Refer to IS31 manual for these locations
 *   driver
 *   |  R location

    ....
}

Where CSx_SWx is the location of the LED in the matrix defined by the datasheet. The driver is the index of the driver you defined in your config.h (0, 1, 2, or 3 for now).

ISSI_MANUAL_SCALING is used to override the Scaling for individual LED's. By default they will be set as per ISSI_SCAL_<colour>. In config.h set how many LED's you want to manually set scaling for. Eg #define ISSI_MANUAL_SCALING 3

Then Define the array listing all the LEDs you want to override in your <keyboard>.c:

const is31_led PROGMEM g_is31_scaling[ISSI_MANUAL_SCALING] = {
/*   LED Index
 *   |  R scaling
 *   |  |    G scaling
 *   |  |    |    B scaling
 *   |  |    |    | */
    {5, 120, 155, 167},
    {9, 120, 155, 167},
    ....
}

Where LED Index is the position of the LED in the g_is31_leds array. The scaling value between 0 and 255 to be written to the Scaling Register.

    ...

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
`HAS_FLAGS(bits, flags)`	n/a	Evaluates to `true` if `bits` has all `flags` set
`HAS_ANY_FLAGS(bits, flags)`	n/a	Evaluates to `true` if `bits` has any `flags` set
`LED_FLAG_NONE`	`0x00`	If this LED has no flags
`LED_FLAG_ALL`	`0xFF`	If this LED has all flags
`LED_FLAG_MODIFIER`	`0x01`	If the LED is on a modifier key
`LED_FLAG_UNDERGLOW`	`0x02`	If the LED is for underglow
`LED_FLAG_KEYLIGHT`	`0x04`	If the LED is for key backlight
`LED_FLAG_INDICATOR`	`0x08`	If the LED is for keyboard state indication

Keycodes :id=keycodes

All RGB keycodes are currently shared with the RGBLIGHT system:

Key	Aliases	Description
`RGB_TOG`		Toggle RGB lighting on or off
`RGB_MODE_FORWARD`	`RGB_MOD`	Cycle through modes, reverse direction when Shift is held
`RGB_MODE_REVERSE`	`RGB_RMOD`	Cycle through modes in reverse, forward direction when Shift is held
`RGB_HUI`		Increase hue, decrease hue when Shift is held
`RGB_HUD`		Decrease hue, increase hue when Shift is held
`RGB_SAI`		Increase saturation, decrease saturation when Shift is held
`RGB_SAD`		Decrease saturation, increase saturation when Shift is held
`RGB_VAI`		Increase value (brightness), decrease value when Shift is held
`RGB_VAD`		Decrease value (brightness), increase value when Shift is held
`RGB_SPI`		Increase effect speed (does not support eeprom yet), decrease speed when Shift is held
`RGB_SPD`		Decrease effect speed (does not support eeprom yet), increase speed when Shift is held
`RGB_MODE_PLAIN`	`RGB_M_P`	Static (no animation) mode
`RGB_MODE_BREATHE`	`RGB_M_B`	Breathing animation mode
`RGB_MODE_RAINBOW`	`RGB_M_R`	Full gradient scrolling left to right (uses the `RGB_MATRIX_CYCLE_LEFT_RIGHT` mode)
`RGB_MODE_SWIRL`	`RGB_M_SW`	Full gradient spinning pinwheel around center of keyboard (uses `RGB_MATRIX_CYCLE_PINWHEEL` mode)

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_MODE_SWIRL are the only ones that are mapped properly. The rest don't have a direct equivalent, and are not mapped.

?> RGB_* keycodes cannot be used with functions like tap_code16(RGB_HUD) as they're not USB HID keycodes. If you wish to replicate similar behaviour in custom code within your firmware (e.g. inside encoder_update_user() or process_record_user()), the equivalent RGB functions should be used instead.

!> 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

As heatmap uses the physical position of the leds set in the g_led_config, you may need to tweak the following options to get the best effect for your keyboard. Note the size of this grid is 224x64.

Limit the distance the effect spreads to surrounding keys.

#define RGB_MATRIX_TYPING_HEATMAP_SPREAD 40

Limit how hot surrounding keys get from each press.

#define RGB_MATRIX_TYPING_HEATMAP_AREA_LIMIT 16

Remove the spread effect entirely.

#define RGB_MATRIX_TYPING_HEATMAP_SLIM

It's also possible to adjust the tempo of heating up. It's defined as the number of shades that are increased on the HSV scale. Decreasing this value increases the number of keystrokes needed to fully heat up the key.

#define RGB_MATRIX_TYPING_HEATMAP_INCREASE_STEP 32

RGB Matrix Effect Solid Reactive :id=rgb-matrix-effect-solid-reactive

Solid reactive effects will pulse RGB light on key presses with user configurable hues. To enable gradient mode that will automatically change reactive color, add the following define:

#define RGB_MATRIX_SOLID_REACTIVE_GRADIENT_MODE

Gradient mode will loop through the color wheel hues over time and its duration can be controlled with the effect speed keycodes (RGB_SPI/RGB_SPD).

Custom RGB Matrix Effects :id=custom-rgb-matrix-effects

By setting RGB_MATRIX_CUSTOM_USER = yes in rules.mk, new effects can be defined directly from your keymap or userspace, without having to edit any QMK core files. To declare new effects, create a rgb_matrix_user.inc file in the user keymap directory or userspace folder.

?> Hardware maintainers who want to limit custom effects to a specific keyboard can create a rgb_matrix_kb.inc file in the root of the keyboard directory, and add RGB_MATRIX_CUSTOM_KB = yes to the keyboard level rules.mk.

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);
}

Indicators :id=indicators

If you want to set custom indicators, such as an LED for Caps Lock, or layer indication, then you can use the rgb_matrix_indicators_kb function on the keyboard level source file, or rgb_matrix_indicators_user function in the user keymap.c.

bool rgb_matrix_indicators_kb(void) {
    if (!rgb_matrix_indicators_user()) {
        return false;
    }
    rgb_matrix_set_color(index, red, green, blue);
    return true;
}

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).

bool rgb_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
    RGB_MATRIX_INDICATOR_SET_COLOR(index, red, green, blue);
    return false;
}

Indicator Examples :id=indicator-examples

Caps Lock indicator on alphanumeric flagged keys:

bool 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);
            }
        }
    }
    return false;
}

Layer indicator on all keys:

bool 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 2:
                rgb_matrix_set_color(i, RGB_BLUE);
                break;
            case 1:
                rgb_matrix_set_color(i, RGB_YELLOW);
                break;
            default:
                break;
        }
    }
    return false;
}

Layer indicator only on keys with configured keycodes:

bool rgb_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
    if (get_highest_layer(layer_state) > 0) {
        uint8_t layer = get_highest_layer(layer_state);

        for (uint8_t row = 0; row < MATRIX_ROWS; ++row) {
            for (uint8_t col = 0; col < MATRIX_COLS; ++col) {
                uint8_t index = g_led_config.matrix_co[row][col];

                if (index >= led_min && index < led_max && index != NO_LED &&
                keymap_key_to_keycode(layer, (keypos_t){col,row}) > KC_TRNS) {
                    rgb_matrix_set_color(index, RGB_GREEN);
                }
            }
        }
    }
    return false;
}

?> Split keyboards will require layer state data syncing with #define SPLIT_LAYER_STATE_ENABLE. See Data Sync Options for more details.

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).

bool 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);
        }
    }
    return false;
}

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:

bool 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);
    }
    return false;
}

?> RGB indicators on split keyboards will require state information synced to the slave half (e.g. #define SPLIT_LAYER_STATE_ENABLE). See data sync options for more details.

Indicators without RGB Matrix Effect

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);
}
