-# RGB Matrix Lighting
+# LED Matrix Lighting
+
+This feature allows you to use LED matrices driven by external drivers. It hooks into the backlight system so you can use the same keycodes as backlighting to control it.
+
+If you want to use RGB LED's you should use the [RGB Matrix Subsystem](feature_rgb_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`:
+There is basic support for addressable LED matrix lighting with the I2C IS31FL3731 RGB controller. To enable it, add this to your `rules.mk`:
LED_MATRIX_ENABLE = IS31FL3731
+
+You can use between 1 and 4 IS31FL3731 IC's. Do not specify `LED_DRIVER_ADDR_<N>` defines for IC's that are not present on your keyboard. You can define the following items in `config.h`:
-Configure the hardware via your `config.h`:
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `ISSI_TIMEOUT` | (Optional) How long to wait for i2c messages | 100 |
+| `ISSI_PERSISTENCE` | (Optional) Retry failed messages this many times | 0 |
+| `LED_DRIVER_COUNT` | (Required) How many LED driver IC's are present | |
+| `LED_DRIVER_LED_COUNT` | (Required) How many LED lights are present across all drivers | |
+| `LED_DRIVER_ADDR_1` | (Required) Address for the first LED driver | |
+| `LED_DRIVER_ADDR_2` | (Optional) Address for the second LED driver | |
+| `LED_DRIVER_ADDR_3` | (Optional) Address for the third LED driver | |
+| `LED_DRIVER_ADDR_4` | (Optional) Address for the fourth LED driver | |
+
+Here is an example using 2 drivers.
// 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)
#define LED_DRIVER_ADDR_2 0b1110110
#define LED_DRIVER_COUNT 2
- #define LED_DRIVER_1_LED_TOTAL 25
- #define LED_DRIVER_2_LED_TOTAL 24
- #define LED_DRIVER_LED_TOTAL LED_DRIVER_1_LED_TOTAL + LED_DRIVER_2_LED_TOTAL
+ #define LED_DRIVER_1_LED_COUNT 25
+ #define LED_DRIVER_2_LED_COUNT 24
+ #define LED_DRIVER_LED_COUNT LED_DRIVER_1_LED_TOTAL + LED_DRIVER_2_LED_TOTAL
Currently only 2 drivers are supported, but it would be trivial to support all 4 combinations.
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},
+ * | LED address
+ * | | */
+ {0, 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) 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}
- * | {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).
+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-simple.h`. The `driver` is the index of the driver you defined in your `config.h` (`0`, `1`, `2`, or `3` ).
## 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
-

+## LED Matrix Effects
+Currently no LED matrix effects have been created.
## 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);
+ void led_matrix_indicators_kb(void) {
+ led_matrix_set_index_value(index, value);
}
-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) 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
-
-## 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`.
+A similar function works in the keymap as `led_matrix_indicators_user`.
## Suspended state
void suspend_power_down_kb(void)
{
- rgb_matrix_set_suspend_state(true);
+ led_matrix_set_suspend_state(true);
}
void suspend_wakeup_init_kb(void)
{
- rgb_matrix_set_suspend_state(false);
+ led_matrix_set_suspend_state(false);
}
