Where `X_Y` is the location of the LED in the matrix defined by [the datasheet](https://www.issi.com/WW/pdf/31FL3733.pdf) and the header file `drivers/led/issi/is31fl3733.h`. The `driver` is the index of the driver you defined in your `config.h` (`0`, `1`, `2`, or `3` for now).

### IS31FL3736 :id=is31fl3736
There is basic support for addressable RGB matrix lighting with the I2C IS31FL3737 RGB controller. To enable it, add this to your `rules.mk`:
```make
RGB_MATRIX_ENABLE = yes
RGB_MATRIX_DRIVER = IS31FL3736
```
You can use between 1 and 4 IS31FL3736 IC's. Do not specify `DRIVER_ADDR_<N>` defines for IC's that are not present on your keyboard.
Configure the hardware via your `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_PWM_FREQUENCY` | (Optional) PWM Frequency Setting - IS31FL3736B only | 0 |
| `ISSI_GLOBALCURRENT` | (Optional) Configuration for the Global Current Register | 0xFF |
| `ISSI_SWPULLUP` | (Optional) Set the value of the SWx lines on-chip de-ghosting resistors | PUR_0R (Disabled) |
| `ISSI_CSPULLUP` | (Optional) Set the value of the CSx lines on-chip de-ghosting resistors | PUR_0R (Disabled) |
| `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 | |
The IS31FL3736 IC's have on-chip resistors that can be enabled to allow for de-ghosting of the RGB matrix. By default these resistors are not enabled (`ISSI_SWPULLUP`/`ISSI_CSPULLUP` are given the value of`PUR_0R`), the values that can be set to enable de-ghosting are as follows:
| `ISSI_SWPULLUP/ISSI_CSPULLUP` | Description |
|----------------------|-------------|
| `PUR_0R` | (default) Do not use the on-chip resistors/enable de-ghosting |
| `PUR_05KR` | The 0.5k Ohm resistor used during blanking period (t_NOL) |
| `PUR_1KR` | The 1k Ohm resistor used during blanking period (t_NOL) |
| `PUR_2KR` | The 2k Ohm resistor used during blanking period (t_NOL) |
| `PUR_4KR` | The 4k Ohm resistor used during blanking period (t_NOL) |
| `PUR_8KR` | The 8k Ohm resistor during blanking period (t_NOL) |
| `PUR_16KR` | The 16k Ohm resistor during blanking period (t_NOL) |
| `PUR_32KR` | The 32k Ohm resistor used during blanking period (t_NOL) |
Here is an example using 2 drivers.
```c
// 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:
// 0000 <-> GND
// 0101 <-> SCL
// 1010 <-> SDA
// 1111 <-> VCC
// ADDR represents A3:A0 of the 7-bit address.
// The result is: 0b101(ADDR)
#define DRIVER_ADDR_1 0b1010000
#define DRIVER_ADDR_2 0b1010001
#define DRIVER_COUNT 2
#define DRIVER_1_LED_TOTAL 30
#define DRIVER_2_LED_TOTAL 36
#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`.
Define these arrays listing all the LEDs in your `<keyboard>.c`:
```c
const is31_led PROGMEM g_is31_leds[RGB_MATRIX_LED_COUNT] = {
/* Refer to IS31 manual for these locations
* driver
* | R location
* | | G location
* | | | B location
* | | | | */
{0, B_1, A_1, C_1},
....
}
```
