Configure the hardware via your `config.h`: 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`:
| 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 |
| `LED_DRIVER_COUNT` | (Required) How many LED driver IC's are present | |
| `DRIVER_LED_TOTAL` | (Required) How many LED lights are present across all drivers | |
| `LED_DRIVER_ADDR_1` | (Required) Address for the first LED driver | |

| `LED_DRIVER_ADDR_3` | (Optional) Address for the third LED driver | |
