There is basic support for addressable LED matrix lighting with the I2C IS31FL3731 RGB controller. To enable it, add this to your `rules.mk`:
LED_MATRIX_ENABLE = yes
LED_MATRIX_DRIVER = IS31FL3731
```make
LED_MATRIX_ENABLE = yes
LED_MATRIX_DRIVER = IS31FL3731
```
You can use between 1 and 4 IS31FL3731 IC's. Do not specify `LED_DRIVER_ADDR_<N>` defines for IC's that are not present on your keyboard. You can define the following items in `config.h`:

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
* | LED address
* | | */
{0, C3_3},
....
}
```c
const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
/* Refer to IS31 manual for these locations
* driver
* | LED address
* | | */
{ 0, C1_1 },
{ 0, C1_15 },
// ...
}
```
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` ).

## Custom layer effects
## Custom Layer Effects
Custom layer effects can be done by defining this in your `<keyboard>.c`:
void led_matrix_indicators_kb(void) {
led_matrix_set_index_value(index, value);
}
```c
void led_matrix_indicators_kb(void) {
led_matrix_set_index_value(index, value);
}
```
A similar function works in the keymap as `led_matrix_indicators_user`.
## Suspended state
## Suspended State
To use the suspend feature, add this to your `<keyboard>.c`:
void suspend_power_down_kb(void)
{
led_matrix_set_suspend_state(true);
}
```c
void suspend_power_down_kb(void) {
led_matrix_set_suspend_state(true);
}
void suspend_wakeup_init_kb(void)
{
led_matrix_set_suspend_state(false);
}
void suspend_wakeup_init_kb(void) {
led_matrix_set_suspend_state(false);
}
