# RGB Matrix Lighting
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
Configure the hardware via your `config.h`:
// 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:
// 0b1110100 AD <-> GND
// 0b1110111 AD <-> VCC
// 0b1110101 AD <-> SCL
// 0b1110110 AD <-> SDA
#define DRIVER_ADDR_1 0b1110100
#define DRIVER_ADDR_2 0b1110110
#define DRIVER_COUNT 2
#define DRIVER_1_LED_TOTAL 25
#define DRIVER_2_LED_TOTAL 24
#define DRIVER_LED_TOTAL DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL
Currently only 2 drivers are supported, but it would be trivial to support all 4 combinations.
Define these arrays listing all the LEDs in your `<keyboard>.c`:
const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
/* 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](http://www.issi.com/WW/pdf/31FL3731.pdf). The `driver` is the index of the driver you defined in your `config.h` (`0` or `1` right now).
const rgb_led g_rgb_leds[DRIVER_LED_TOTAL] = {
/* {row | col << 4}
* | {x=0..224, y=0..64}
* | | modifier
* | | | */
{{0|(0<<4)}, {20.36*0, 21.33*0}, 1},
{{0|(1<<4)}, {20.36*1, 21.33*0}, 1},
....
}
The format for the matrix position used in this array is `{row | (col << 4)}`. The `x` is between (inclusive) 0-224, and `y` is between (inclusive) 0-64. The easiest way to calculate these positions is:
x = 224 / ( NUMBER_OF_ROWS - 1 ) * ROW_POSITION
y = 64 / (NUMBER_OF_COLS - 1 ) * COL_POSITION
Where all variables are decimels/floats.
`modifier` is a boolean, whether or not a certain key is considered a modifier (used in some effects).
## Keycodes
All RGB keycodes are currently shared with the RGBLIGHT system:
* `RGB_TOG` - toggle
* `RGB_MOD` - cycle through modes
* `RGB_HUI` - increase hue
* `RGB_HUD` - decrease hue
* `RGB_SAI` - increase saturation
* `RGB_SAD` - decrease saturation
* `RGB_VAI` - increase value
* `RGB_VAD` - decrease value
* `RGB_MODE_*` keycodes will generally work, but are not currently mapped to the correct effects for the RGB Matrix system
## RGB Matrix Effects
These are the effects that are currently available:
enum rgb_matrix_effects {
RGB_MATRIX_SOLID_COLOR = 1,
RGB_MATRIX_SOLID_REACTIVE,
RGB_MATRIX_ALPHAS_MODS,
RGB_MATRIX_DUAL_BEACON,
RGB_MATRIX_GRADIENT_UP_DOWN,
RGB_MATRIX_RAINDROPS,
RGB_MATRIX_CYCLE_ALL,
RGB_MATRIX_CYCLE_LEFT_RIGHT,
RGB_MATRIX_CYCLE_UP_DOWN,
RGB_MATRIX_RAINBOW_BEACON,
RGB_MATRIX_RAINBOW_PINWHEELS,
RGB_MATRIX_RAINBOW_MOVING_CHEVRON,
RGB_MATRIX_JELLYBEAN_RAINDROPS,
#ifdef RGB_MATRIX_KEYPRESSES
RGB_MATRIX_SPLASH,
RGB_MATRIX_MULTISPLASH,
RGB_MATRIX_SOLID_SPLASH,
RGB_MATRIX_SOLID_MULTISPLASH,
#endif
RGB_MATRIX_EFFECT_MAX
};
## Custom layer effects
Custom layer effects can be done by defining this in your `<keyboard>.c`:
void rgb_matrix_indicators_kb(void) {
// rgb_matrix_set_color(index, red, green, blue);
}
A similar function works in the keymap as `rgb_matrix_indicators_user`.
## Additional `config.h` Options
#define RGB_MATRIX_KEYPRESSES // reacts to keypresses (will slow down matrix scan by a lot)
#define RGB_MATRIX_KEYRELEASES // reacts to keyreleases (not recommened)
#define RGB_DISABLE_AFTER_TIMEOUT 0 // number of ticks to wait until disabling effects
#define RGB_DISABLE_WHEN_USB_SUSPENDED false // turn off effects when suspended
#define RGB_MATRIX_SKIP_FRAMES 1 // number of frames to skip when displaying animations (0 is full effect)
## EEPROM storage
The EEPROM for it is currently shared with the RGBLIGHT system (it's generally assumed only one RGB would be used at a time), but could be configured to use its own 32bit address with:
#define EECONFIG_RGB_MATRIX (uint32_t *)16
Where `16` is an unused index from `eeconfig.h`.
## Suspended state
To use the suspend feature, add this to your `<keyboard>.c`:
void suspend_power_down_kb(void)
{
rgb_matrix_set_suspend_state(true);
}
void suspend_wakeup_init_kb(void)
{
rgb_matrix_set_suspend_state(false);
}
