# LED Matrix Lighting :id=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.

There is basic support for addressable LED matrix lighting with the I2C IS31FL3731 LED controller. To enable it, add this to your `rules.mk`:
|
||||
|
||||
```make
|
||||
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 | |
|
||||
| `DRIVER_LED_TOTAL` | (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.
|
||||
Configure the hardware via your `config.h`:
|
||||
|
||||
```c
|
||||
// This is a 7-bit address, that gets left-shifted and bit 0

As an example, `rand() % (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)` will give very different results than `rand() % 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`:
|
||||
|
||||
```c
|
||||
const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
|
||||
/* Refer to IS31 manual for these locations
|
||||
* driver
|
||||
* | LED address
|
||||
* | | */
|
||||
{ 0, C1_1 },
|
||||
{ 0, C1_15 },
|
||||
// ...
|
||||
}
|
||||
const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
|
||||
/* Refer to IS31 manual for these locations
|
||||
* driver
|
||||
* | LED address
|
||||
* | | */
|
||||
{ 0, C1_1 },
|
||||
{ 0, C1_15 },
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
Where `Cx_y` is the location of the LED in the matrix defined by [the datasheet](https://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`:
|
||||
From this point forward the configuration is the same for all the drivers. The `led_config_t` struct provides a key electrical matrix to led index lookup table, what the physical position of each LED is on the board, and what type of key or usage the LED if the LED represents. Here is a brief example:
|
||||
|
||||
```c
|
||||
led_config_t g_led_config = { {
|
||||
// Key Matrix to LED Index
|
||||
{ 5, NO_LED, NO_LED, 0 },
|
||||
{ NO_LED, NO_LED, NO_LED, NO_LED },
|
||||
{ 4, NO_LED, NO_LED, 1 },
|
||||
{ 3, NO_LED, NO_LED, 2 }
|
||||
}, {
|
||||
// LED Index to Physical Position
|
||||
{ 188, 16 }, { 187, 48 }, { 149, 64 }, { 112, 64 }, { 37, 48 }, { 38, 16 }
|
||||
}, {
|
||||
// LED Index to Flag
|
||||
1, 4, 4, 4, 4, 1
|
||||
} };
|
||||
```
|
||||
|
||||
The first part, `// Key Matrix to LED Index`, tells the system what key this LED represents by using the key's electrical matrix row & col. The second part, `// LED Index to Physical Position` represents the LED's physical `{ x, y }` position on the keyboard. The default expected range of values for `{ x, y }` is the inclusive range `{ 0..224, 0..64 }`. This default expected range is due to effects that calculate the center of the keyboard for their animations. The easiest way to calculate these positions is imagine your keyboard is a grid, and the top left of the keyboard represents `{ x, y }` coordinate `{ 0, 0 }` and the bottom right of your keyboard represents `{ 224, 64 }`. Using this as a basis, you can use the following formula to calculate the physical position:
|
||||
|
||||
```c
|
||||
x = 224 / (NUMBER_OF_COLS - 1) * COL_POSITION
|
||||
y = 64 / (NUMBER_OF_ROWS - 1) * ROW_POSITION
|
||||
```
|
||||
|
||||
Where NUMBER_OF_COLS, NUMBER_OF_ROWS, COL_POSITION, & ROW_POSITION are all based on the physical layout of your keyboard, not the electrical layout.
|
||||
|
||||
As mentioned earlier, the center of the keyboard by default is expected to be `{ 112, 32 }`, but this can be changed if you want to more accurately calculate the LED's physical `{ x, y }` positions. Keyboard designers can implement `#define LED_MATRIX_CENTER { 112, 32 }` in their config.h file with the new center point of the keyboard, or where they want it to be allowing more possibilities for the `{ x, y }` values. Do note that the maximum value for x or y is 255, and the recommended maximum is 224 as this gives animations runoff room before they reset.
|
||||
|
||||
`// LED Index to Flag` is a bitmask, whether or not a certain LEDs is of a certain type. It is recommended that LEDs are set to only 1 type.
|
||||
|
||||
## Flags :id=flags

||||

|

## Custom LED Matrix Effects :id=custom-led-matrix-effects
|
||||
|
||||
By setting `LED_MATRIX_CUSTOM_USER` (and/or `LED_MATRIX_CUSTOM_KB`) in `rules.mk`, new effects can be defined directly from userspace, without having to edit any QMK core files.
|
||||
|
||||
To declare new effects, create a new `led_matrix_user/kb.inc` that looks something like this:
|
||||
|
||||
`led_matrix_user.inc` should go in the root of the keymap directory.
|
||||
`led_matrix_kb.inc` should go in the root of the keyboard directory.
|
||||
|
||||
To use custom effects in your code, simply prepend `LED_MATRIX_CUSTOM_` to the effect name specified in `LED_MATRIX_EFFECT()`. For example, an effect declared as `LED_MATRIX_EFFECT(my_cool_effect)` would be referenced with:
|
||||
|
||||
```c
|
||||
led_matrix_mode(led_MATRIX_CUSTOM_my_cool_effect);
|
||||
```
|
||||
|
||||
```c
|
||||
// !!! DO NOT ADD #pragma once !!! //
|
||||
|
||||
// Step 1.
|
||||
// Declare custom effects using the LED_MATRIX_EFFECT macro
|
||||
// (note the lack of semicolon after the macro!)
|
||||
LED_MATRIX_EFFECT(my_cool_effect)
|
||||
LED_MATRIX_EFFECT(my_cool_effect2)
|
||||
|
||||
// Step 2.
|
||||
// Define effects inside the `LED_MATRIX_CUSTOM_EFFECT_IMPLS` ifdef block
|
||||
#ifdef LED_MATRIX_CUSTOM_EFFECT_IMPLS
|
||||
|
||||
// e.g: A simple effect, self-contained within a single method
|
||||
static bool my_cool_effect(effect_params_t* params) {
|
||||
LED_MATRIX_USE_LIMITS(led_min, led_max);
|
||||
for (uint8_t i = led_min; i < led_max; i++) {
|
||||
led_matrix_set_value(i, 0xFF);
|
||||
}
|
||||
return led_max < DRIVER_LED_TOTAL;
|
||||
}
|
||||
|
||||
// e.g: A more complex effect, relying on external methods and state, with
|
||||
// dedicated init and run methods
|
||||
static uint8_t some_global_state;
|
||||
static void my_cool_effect2_complex_init(effect_params_t* params) {
|
||||
some_global_state = 1;
|
||||
}
|
||||
static bool my_cool_effect2_complex_run(effect_params_t* params) {
|
||||
LED_MATRIX_USE_LIMITS(led_min, led_max);
|
||||
for (uint8_t i = led_min; i < led_max; i++) {
|
||||
led_matrix_set_value(i, some_global_state++);
|
||||
}
|
||||
|
||||
return led_max < DRIVER_LED_TOTAL;
|
||||
}
|

static bool my_cool_effect2(effect_params_t* params) {
|

if (params->init) my_cool_effect2_complex_init(params);
|

return my_cool_effect2_complex_run(params);
|
||||
}
|
||||
|
||||
#endif // LED_MATRIX_CUSTOM_EFFECT_IMPLS

## EEPROM storage :id=eeprom-storage
|

```c
|
||||
#define EECONFIG_LED_MATRIX (uint32_t *)28

### Indicators :id=indicators
|
||||
|
||||
If you want to set custom indicators, such as an LED for Caps Lock, or layer indication, you can use the `led_matrix_indicators_kb` or `led_matrix_indicators_user` function for that:
|
||||
```c
|
||||
void led_matrix_indicators_kb(void) {
|
||||
led_matrix_set_value(index, value);
|
||||
led_matrix_set_color(index, value);
|
||||
}
|
||||
```
|
||||
|
||||
A similar function works in the keymap as `led_matrix_indicators_user`.
|
||||
In addition, there are the advanced indicator functions. These are aimed at those with heavily customized displays, where rendering every LED per cycle is expensive. This includes a special macro to help make this easier to use: `LED_MATRIX_INDICATOR_SET_VALUE(i, v)`.
|
||||
|
||||
## Suspended State
|
||||
```c
|
||||
void led_matrix_indicators_advanced_user(uint8_t led_min, uint8_t led_max) {
|
||||
LED_MATRIX_INDICATOR_SET_VALUE(index, value);
|
||||
}
|
||||
```
|
||||
|
||||
To use the suspend feature, add this to your `<keyboard>.c`:
|
||||
## Suspended State :id=suspended-state
|
||||
To use the suspend feature, make sure that `#define LED_DISABLE_WHEN_USB_SUSPENDED true` is added to the `config.h` file.
|
||||
|
||||
Additionally add this to your `<keyboard>.c`:
|
||||
|
||||
```c
|
||||
void suspend_power_down_kb(void) {
|
||||
led_matrix_set_suspend_state(true);
|
||||
suspend_power_down_user();
|
||||
}
|
||||
|
||||
void suspend_wakeup_init_kb(void) {
|
||||
led_matrix_set_suspend_state(false);
|
||||
suspend_wakeup_init_user();
|
||||
}
|
||||
```
|
||||
```
|
||||
or add this to your `keymap.c`:
|
||||
```c
|
||||
void suspend_power_down_user(void) {
|
||||
led_matrix_set_suspend_state(true);
|
||||
}
|
||||
|
||||
void suspend_wakeup_init_user(void) {
|
||||
led_matrix_set_suspend_state(false);
|
||||
}
|
||||
```
