* Added Modular keyboards L,R and NUM Created code modules for the 3 modules of the modular keyboard. Original idea by MechboardsUK. Uses i2c implementation similar to lets split * Remove modular from master This is to fix incorrect branching * Add effect speed support for RGB Matrix *No eeprom yet* Keycodes RGB_SPI and RGB_SPD have been added to increase and decrease effect speed. Speed is not saved in EEPROM yet as per Jack's request. * Update rgb_matrix.c * RGB Matrix speed fix rgblight.h * More fixes for rgb speed. Speed functions declared but not used in rgblight * More travis fixes.. * Another one for travis..

# 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_SPI` - increase speed effect (no EEPROM support)
|
|
* `RGB_SPD` - decrease speed effect (no EEPROM support)
|
|
|
|
|
|
* `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);
|
|
}
|
