LED (Mono color backlight)

Want your keyboard to shine? Add some lights!

Enabling the extension​

The only required values that you need to give the LED extension would be the led_pin. It can either be a single board pin, or a list of pins for multiple LED's.

from kmk.extensions.LED import LED
import board

led_ext = LED(led_pin=[board.GP0, board.GP1])
keyboard.extensions.append(led_ext)

[Keycodes]​

KeyAliasesDescription
KC.LED_TOG()Toggles LED's
KC.LED_INC()Increase Brightness

KC.LED_ANIIncrease animation speed
KC.LED_ANDDecrease animation speed
KC.LED_MODE_PLAINLED_M_PStatic LED's
KC.LED_MODE_BREATHELED_M_BBreathing animation

Keycodes with arguments can affect all, or a selection of LED's.

# toggle all LEDs
LED_TOG_ALL = KC.LED_TOG()

# increase brightness of first LED
LED_INC_0 = KC.LED_INC(0)

# decrease brightness of second and third LED
LED_DEC_1_2 = KC.LED_DEC(1,2)

Configuration​

All of these values can be set by default for when the keyboard boots.

from kmk.extensions.led import AnimationModes
led_ext = LED(
led_pin=led_pin,
brightness_step=5,
brightness_limit=100,
breathe_center=1.5,
animation_mode=AnimationModes.STATIC,
animation_speed=1,
user_animation=None,
val=100,
)
