# 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 LED matrix lighting with the I2C IS31FL3731 RGB controller. To enable it, add this to your `rules.mk`:
|
|
|
|
LED_MATRIX_ENABLE = yes
|
|
LED_MATRIX_DRIVER = 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`:
|
|
|
|
| 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)
|
|
// The address will vary depending on your wiring:
|
|
// 0b1110100 AD <-> GND
|
|
// 0b1110111 AD <-> VCC
|
|
// 0b1110101 AD <-> SCL
|
|
// 0b1110110 AD <-> SDA
|
|
#define LED_DRIVER_ADDR_1 0b1110100
|
|
#define LED_DRIVER_ADDR_2 0b1110110
|
|
|
|
#define LED_DRIVER_COUNT 2
|
|
#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.
|
|
|
|
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
|
|
* | 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-simple.h`. The `driver` is the index of the driver you defined in your `config.h` (`0`, `1`, `2`, or `3` ).
|
|
|
|
## Keycodes
|
|
|
|
All LED matrix keycodes are currently shared with the [backlight system](feature_backlight.md).
|
|
|
|
## 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 led_matrix_indicators_kb(void) {
|
|
led_matrix_set_index_value(index, value);
|
|
}
|
|
|
|
A similar function works in the keymap as `led_matrix_indicators_user`.
|
|
|
|
## Suspended state
|
|
|
|
To use the suspend feature, add this to your `<keyboard>.c`:
|
|
|
|
void suspend_power_down_kb(void)
|
|
{
|
|
led_matrix_set_suspend_state(true);
|
|
}
|
|
|
|
void suspend_wakeup_init_kb(void)
|
|
{
|
|
led_matrix_set_suspend_state(false);
|
|
}
|
