+# RGB Matrix Lighting
+
+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
+
+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:
+ // 0b1110100 AD <-> GND
+ // 0b1110111 AD <-> VCC
+ // 0b1110101 AD <-> SCL
+ // 0b1110110 AD <-> SDA
+ #define DRIVER_ADDR_1 0b1110100
+ #define DRIVER_ADDR_2 0b1110110
+
+ #define DRIVER_COUNT 2
+ #define DRIVER_1_LED_TOTAL 25
+ #define DRIVER_2_LED_TOTAL 24
+ #define DRIVER_LED_TOTAL DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL
+
+Currently only 2 drivers are supported, but it would be trivial to support all 4 combinations.
+
+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, C1_3, C2_3, C3_3},
+ ....
+ }
+
+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).
+
+ const rgb_led g_rgb_leds[DRIVER_LED_TOTAL] = {
+ /* {row | col << 4}
+ * | {x=0..224, y=0..64}
+ * | | modifier
+ * | | | */
+ {{0|(0<<4)}, {20.36*0, 21.33*0}, 1},
+ {{0|(1<<4)}, {20.36*1, 21.33*0}, 1},
+ ....
+ }
+
+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:
+
+ * `RGB_TOG` - toggle
+ * `RGB_MOD` - cycle through modes
+ * `RGB_HUI` - increase hue
+ * `RGB_HUD` - decrease hue
+ * `RGB_SAI` - increase saturation
+ * `RGB_SAD` - decrease saturation
+ * `RGB_VAI` - increase value
+ * `RGB_VAD` - decrease value
+
+
+ * `RGB_MODE_*` keycodes will generally work, but are not currently mapped to the correct effects for the RGB Matrix system
+
+## RGB Matrix Effects
+
+These are the effects that are currently available:
+
+ enum rgb_matrix_effects {
+ RGB_MATRIX_SOLID_COLOR = 1,
+ RGB_MATRIX_SOLID_REACTIVE,
+ RGB_MATRIX_ALPHAS_MODS,
+ RGB_MATRIX_DUAL_BEACON,
+ RGB_MATRIX_GRADIENT_UP_DOWN,
+ RGB_MATRIX_RAINDROPS,
+ RGB_MATRIX_CYCLE_ALL,
+ RGB_MATRIX_CYCLE_LEFT_RIGHT,
+ RGB_MATRIX_CYCLE_UP_DOWN,
+ RGB_MATRIX_RAINBOW_BEACON,
+ RGB_MATRIX_RAINBOW_PINWHEELS,
+ RGB_MATRIX_RAINBOW_MOVING_CHEVRON,
+ RGB_MATRIX_JELLYBEAN_RAINDROPS,
+ #ifdef RGB_MATRIX_KEYPRESSES
+ RGB_MATRIX_SPLASH,
+ RGB_MATRIX_MULTISPLASH,
+ RGB_MATRIX_SOLID_SPLASH,
+ RGB_MATRIX_SOLID_MULTISPLASH,
+ #endif
+ RGB_MATRIX_EFFECT_MAX
+ };
+
+## 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);
+ }
+
+A similar function works in the keymap as `rgb_matrix_indicators_user`.
+
+## Additional `config.h` Options
+
+ #define RGB_MATRIX_KEYPRESSES // reacts to keypresses (will slow down matrix scan by a lot)
+ #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)
+
+## EEPROM storage
+
+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`:
+
+ void suspend_power_down_kb(void)
+ {
+ rgb_matrix_set_suspend_state(true);
+ }
+
+ void suspend_wakeup_init_kb(void)
+ {
+ rgb_matrix_set_suspend_state(false);
+ }
