Where `Cx_y` is the location of the LED in the matrix defined by [the datasheet](http://www.issi.com/WW/pdf/31FL3731.pdf) and the header file `drivers/issi/is31fl3731.h`. The `driver` is the index of the driver you defined in your `config.h` (`0` or `1` right now).
### IS31FL3733
There is basic support for addressable RGB matrix lighting with the I2C IS31FL3733 RGB controller. To enable it, add this to your `rules.mk`:
RGB_MATRIX_ENABLE = IS31FL3733
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:
// 00 <-> GND
// 01 <-> SCL
// 10 <-> SDA
// 11 <-> VCC
// ADDR1 represents A1:A0 of the 7-bit address.
// ADDR2 represents A3:A2 of the 7-bit address.
// The result is: 0b101(ADDR2)(ADDR1)
#define DRIVER_ADDR_1 0b1010000
#define DRIVER_ADDR_2 0b1010000 // this is here for compliancy reasons.
#define DRIVER_COUNT 1
#define DRIVER_1_LED_TOTAL 64
#define DRIVER_LED_TOTAL DRIVER_1_LED_TOTAL
Currently only a single drivers is supported, but it would be trivial to support all 4 combinations. For now define `DRIVER_ADDR_2` as `DRIVER_ADDR_1`
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, B_1, A_1, C_1},
....
}
Where `X_Y` is the location of the LED in the matrix defined by [the datasheet](http://www.issi.com/WW/pdf/31FL3733.pdf) and the header file `drivers/issi/is31fl3733.h`. The `driver` is the index of the driver you defined in your `config.h` (Only `0` right now).
From this point forward the configuration is the same for all the drivers.
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:
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`:
