# RGB Matrix Lighting
+This feature allows you to use RGB LED matrices driven by external drivers. It hooks into the RGBLIGHT system so you can use the same keycodes as RGBLIGHT to control it.
+
+If you want to use single color LED's you should use the [LED Matrix Subsystem](feature_led_matrix.md) instead.
+
+## Driver configuration
+
+### IS31FL3731
+
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
+ RGB_MATRIX_ENABLE = IS31FL3731
Configure the hardware via your `config.h`:
....
}
-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).
+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.
const rgb_led g_rgb_leds[DRIVER_LED_TOTAL] = {
/* {row | col << 4}
These are the effects that are currently available:
enum rgb_matrix_effects {
- RGB_MATRIX_SOLID_COLOR = 1,
+ RGB_MATRIX_SOLID_COLOR = 1,
RGB_MATRIX_ALPHAS_MODS,
RGB_MATRIX_DUAL_BEACON,
RGB_MATRIX_GRADIENT_UP_DOWN,
RGB_MATRIX_RAINBOW_PINWHEELS,
RGB_MATRIX_RAINBOW_MOVING_CHEVRON,
RGB_MATRIX_JELLYBEAN_RAINDROPS,
+ RGB_MATRIX_DIGITAL_RAIN,
#ifdef RGB_MATRIX_KEYPRESSES
- RGB_MATRIX_SOLID_REACTIVE,
+ RGB_MATRIX_SOLID_REACTIVE,
RGB_MATRIX_SPLASH,
RGB_MATRIX_MULTISPLASH,
RGB_MATRIX_SOLID_SPLASH,
#endif
RGB_MATRIX_EFFECT_MAX
};
+
+You can disable a single effect by defining `DISABLE_[EFFECT_NAME]` in your `config.h`:
+
+
+|Define |Description |
+|---------------------------------------------------|--------------------------------------------|
+|`#define DISABLE_RGB_MATRIX_ALPHAS_MODS` |Disables `RGB_MATRIX_ALPHAS_MODS` |

## 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);
+ rgb_matrix_set_color(index, red, green, blue);
}
A similar function works in the keymap as `rgb_matrix_indicators_user`.
