3 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.
5 If you want to use single color LED's you should use the [LED Matrix Subsystem](feature_led_matrix.md) instead.
7 ## Driver configuration
11 There is basic support for addressable RGB matrix lighting with the I2C IS31FL3731 RGB controller. To enable it, add this to your `rules.mk`:
14 RGB_MATRIX_ENABLE = IS31FL3731
17 Configure the hardware via your `config.h`:
20 // This is a 7-bit address, that gets left-shifted and bit 0
21 // set to 0 for write, 1 for read (as per I2C protocol)
22 // The address will vary depending on your wiring:
23 // 0b1110100 AD <-> GND
24 // 0b1110111 AD <-> VCC
25 // 0b1110101 AD <-> SCL
26 // 0b1110110 AD <-> SDA
27 #define DRIVER_ADDR_1 0b1110100
28 #define DRIVER_ADDR_2 0b1110110
30 #define DRIVER_COUNT 2
31 #define DRIVER_1_LED_TOTAL 25
32 #define DRIVER_2_LED_TOTAL 24
33 #define DRIVER_LED_TOTAL DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL
36 Currently only 2 drivers are supported, but it would be trivial to support all 4 combinations.
38 Define these arrays listing all the LEDs in your `<keyboard>.c`:
41 const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
42 /* Refer to IS31 manual for these locations
48 {0, C1_3, C2_3, C3_3},
53 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).
55 ### IS31FL3733/IS31FL3737
57 !> For the IS31FL3737, replace all instances of `IS31FL3733` below with `IS31FL3737`.
59 There is basic support for addressable RGB matrix lighting with the I2C IS31FL3733 RGB controller. To enable it, add this to your `rules.mk`:
62 RGB_MATRIX_ENABLE = IS31FL3733
65 Configure the hardware via your `config.h`:
68 // This is a 7-bit address, that gets left-shifted and bit 0
69 // set to 0 for write, 1 for read (as per I2C protocol)
70 // The address will vary depending on your wiring:
75 // ADDR1 represents A1:A0 of the 7-bit address.
76 // ADDR2 represents A3:A2 of the 7-bit address.
77 // The result is: 0b101(ADDR2)(ADDR1)
78 #define DRIVER_ADDR_1 0b1010000
79 #define DRIVER_ADDR_2 0b1010000 // this is here for compliancy reasons.
81 #define DRIVER_COUNT 2
82 #define DRIVER_1_LED_TOTAL 64
83 #define DRIVER_LED_TOTAL DRIVER_1_LED_TOTAL
86 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`
88 Define these arrays listing all the LEDs in your `<keyboard>.c`:
91 const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
92 /* Refer to IS31 manual for these locations
103 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).
105 From this point forward the configuration is the same for all the drivers.
108 const rgb_led g_rgb_leds[DRIVER_LED_TOTAL] = {
110 * | {x=0..224, y=0..64}
113 {{0|(0<<4)}, {20.36*0, 21.33*0}, 1},
114 {{0|(1<<4)}, {20.36*1, 21.33*0}, 1},
119 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:
122 x = 224 / ( NUMBER_OF_COLS - 1 ) * ROW_POSITION
123 y = 64 / (NUMBER_OF_ROWS - 1 ) * COL_POSITION
126 Where all variables are decimels/floats.
128 `modifier` is a boolean, whether or not a certain key is considered a modifier (used in some effects).
132 All RGB keycodes are currently shared with the RGBLIGHT system:
135 * `RGB_MOD` - cycle through modes
136 * `RGB_HUI` - increase hue
137 * `RGB_HUD` - decrease hue
138 * `RGB_SAI` - increase saturation
139 * `RGB_SAD` - decrease saturation
140 * `RGB_VAI` - increase value
141 * `RGB_VAD` - decrease value
142 * `RGB_SPI` - increase speed effect (no EEPROM support)
143 * `RGB_SPD` - decrease speed effect (no EEPROM support)
144 * `RGB_MODE_*` keycodes will generally work, but are not currently mapped to the correct effects for the RGB Matrix system
146 ## RGB Matrix Effects
148 All effects have been configured to support current configuration values (Hue, Saturation, Value, & Speed) unless otherwise noted below. These are the effects that are currently available:
151 enum rgb_matrix_effects {
153 RGB_MATRIX_SOLID_COLOR = 1, // Static single hue, no speed support
154 RGB_MATRIX_ALPHAS_MODS, // Static dual hue, speed is hue for secondary hue
155 RGB_MATRIX_GRADIENT_UP_DOWN, // Static gradient top to bottom, speed controls how much gradient changes
156 RGB_MATRIX_BREATHING, // Single hue brightness cycling animation
157 RGB_MATRIX_CYCLE_ALL, // Full keyboard solid hue cycling through full gradient
158 RGB_MATRIX_CYCLE_LEFT_RIGHT, // Full gradient scrolling left to right
159 RGB_MATRIX_CYCLE_UP_DOWN, // Full gradient scrolling top to bottom
160 RGB_MATRIX_RAINBOW_MOVING_CHEVRON, // Full gradent Chevron shapped scrolling left to right
161 RGB_MATRIX_DUAL_BEACON, // Full gradient spinning around center of keyboard
162 RGB_MATRIX_RAINBOW_BEACON, // Full tighter gradient spinning around center of keyboard
163 RGB_MATRIX_RAINBOW_PINWHEELS, // Full dual gradients spinning two halfs of keyboard
164 RGB_MATRIX_RAINDROPS, // Randomly changes a single key's hue
165 RGB_MATRIX_JELLYBEAN_RAINDROPS, // Randomly changes a single key's hue and saturation
166 RGB_MATRIX_DIGITAL_RAIN, // That famous computer simulation
167 #if defined(RGB_MATRIX_KEYPRESSES) || defined(RGB_MATRIX_KEYRELEASES)
168 RGB_MATRIX_SOLID_REACTIVE_SIMPLE, // Pulses keys hit to hue & value then fades value out
169 RGB_MATRIX_SOLID_REACTIVE, // Static single hue, pulses keys hit to shifted hue then fades to current hue
170 RGB_MATRIX_SPLASH, // Full gradient & value pulse away from a single key hit then fades value out
171 RGB_MATRIX_MULTISPLASH, // Full gradient & value pulse away from multiple key hits then fades value out
172 RGB_MATRIX_SOLID_SPLASH, // Hue & value pulse away from a single key hit then fades value out
173 RGB_MATRIX_SOLID_MULTISPLASH, // Hue & value pulse away from multiple key hits then fades value out
175 RGB_MATRIX_EFFECT_MAX
179 You can disable a single effect by defining `DISABLE_[EFFECT_NAME]` in your `config.h`:

202 |`#define DISABLE_RGB_MATRIX_SOLID_MULTISPLASH` |Disables `RGB_MATRIX_SOLID_MULTISPLASH` |
205 ## Custom layer effects
207 Custom layer effects can be done by defining this in your `<keyboard>.c`:
210 void rgb_matrix_indicators_kb(void) {
211 rgb_matrix_set_color(index, red, green, blue);
215 A similar function works in the keymap as `rgb_matrix_indicators_user`.
217 ## Additional `config.h` Options
220 #define RGB_MATRIX_KEYPRESSES // reacts to keypresses
221 #define RGB_MATRIX_KEYRELEASES // reacts to keyreleases (instead of keypresses)
222 #define RGB_DISABLE_AFTER_TIMEOUT 0 // number of ticks to wait until disabling effects
223 #define RGB_DISABLE_WHEN_USB_SUSPENDED false // turn off effects when suspended
224 #define RGB_MATRIX_LED_PROCESS_LIMIT (DRIVER_LED_TOTAL + 4) / 5 // limits the number of LEDs to process in an animation per task run (increases keyboard responsiveness)
225 #define RGB_MATRIX_LED_FLUSH_LIMIT 16 // limits in milliseconds how frequently an animation will update the LEDs. 16 (16ms) is equivalent to limiting to 60fps (increases keyboard responsiveness)
226 #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
231 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:
234 #define EECONFIG_RGB_MATRIX (uint32_t *)16
237 Where `16` is an unused index from `eeconfig.h`.
241 To use the suspend feature, add this to your `<keyboard>.c`:
244 void suspend_power_down_kb(void)
246 rgb_matrix_set_suspend_state(true);
249 void suspend_wakeup_init_kb(void)
251 rgb_matrix_set_suspend_state(false);
