# RGB Matrix Lighting
+## 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_REACTIVE,
+ 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_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` |
+|`#define DISABLE_RGB_MATRIX_DUAL_BEACON` |Disables `RGB_MATRIX_DUAL_BEACON` |
+|`#define DISABLE_RGB_MATRIX_GRADIENT_UP_DOWN` |Disables `RGB_MATRIX_GRADIENT_UP_DOWN` |

## 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`.
#define RGB_MATRIX_KEYRELEASES // reacts to keyreleases (not recommened)
#define RGB_DISABLE_AFTER_TIMEOUT 0 // number of ticks to wait until disabling effects
#define RGB_DISABLE_WHEN_USB_SUSPENDED false // turn off effects when suspended
- #define RGB_MATRIX_SKIP_FRAMES 1 // number of frames to skip when displaying animations (0 is full effect)
+ #define RGB_MATRIX_SKIP_FRAMES 1 // number of frames to skip when displaying animations (0 is full effect) if not defined defaults to 1
+ #define RGB_MATRIX_MAXIMUM_BRIGHTNESS 200 // limits maximum brightness of LEDs to 200 out of 255. If not defined maximum brightness is set to 255
