@ -106,10 +106,8 @@ There are two ways to get the host LED state:
## `led_set_user()`
This function will be called when the state of one of those 5 LEDs changes.
It receives the LED state as parameter.
Use the `IS_LED_ON(USB_LED, LED_NAME)` and `IS_LED_OFF(USB_LED, LED_NAME)`
macros to check the LED status.

This is useful for reading the LED state outside `led_set_*`, e.g. in [`matrix_scan_user()`](#matrix-scanning-code).

For convenience, you can use the `IS_HOST_LED_ON(led_name)` and `IS_HOST_LED_OFF(led_name)` macros instead of calling and checking `host_keyboard_leds()` directly.

## Setting physical LED state
## Setting Physical LED State
Some keyboard implementations provide convenience methods for setting the state of the physical LEDs.
### Ergodox and Ergodox EZ
### Ergodox Boards
The Ergodox EZ implementation provides `ergodox_right_led_``1`/`2`/`3_on`/`off()`
to turn individual LEDs on and off, as well as
`ergodox_right_led_on`/`off(uint8_t led)`
to turn them on and off by their number.
The Ergodox implementations provide `ergodox_right_led_1`/`2`/`3_on`/`off()` to turn individual LEDs on or off, as well as `ergodox_right_led_on`/`off(uint8_t led)` to turn them on or off by their index.
In addition, it is possible to specify the brightness level with `ergodox_led_all_set(uint8_t n)`,
for individual LEDs with `ergodox_right_led_1`/`2`/`3_set(uint8_t n)`
or by their number using `ergodox_right_led_set(uint8_t led, uint8_t n)`.
In addition, it is possible to specify the brightness level of all LEDs with `ergodox_led_all_set(uint8_t n)`; of individual LEDs with `ergodox_right_led_1`/`2`/`3_set(uint8_t n)`; or by index with `ergodox_right_led_set(uint8_t led, uint8_t n)`.
It defines `LED_BRIGHTNESS_LO` for the lowest brightness and `LED_BRIGHTNESS_HI` for the highest brightness, which is also the default.
Ergodox boards also define `LED_BRIGHTNESS_LO` for the lowest brightness and `LED_BRIGHTNESS_HI` for the highest brightness (which is the default).
