@ -101,6 +101,13 @@ The `host_keyboard_led_state()` function will report the LED state returned from
bool caps = host_keyboard_led_state().caps_lock; bool caps = host_keyboard_led_state().caps_lock;
``` ```
## `led_update_ports()`
This function writes the LED state to the actual hardware. Call it manually
from your `led_update_*()` callbacks to modify the handling of the standard
keyboard LEDs.
For example when repurposing a standard LED indicator as layer indicator.
## Setting Physical LED State ## Setting Physical LED State
Some keyboard implementations provide convenient methods for setting the state of the physical LEDs. Some keyboard implementations provide convenient methods for setting the state of the physical LEDs.
