-### Example `led_set_kb()` Implementation
+### Example `led_set_user()` Implementation
```
-void led_set_kb(uint8_t usb_led) {
+void led_set_user(uint8_t usb_led) {
if (usb_led & (1<<USB_LED_NUM_LOCK)) {
PORTB |= (1<<0);
} else {
This example, at the keyboard level, sets up B1, B2, and B3 as LED pins.
```
-void matrix_init_kb(void) {
+void matrix_init_user(void) {
// Call the keymap level matrix init.
- matrix_init_user();
// Set our LED pins as output
DDRB |= (1<<1);
This function gets called at every matrix scan, which is basically as often as the MCU can handle. Be careful what you put here, as it will get run a lot.
You should use this function if you need custom matrix scanning code. It can also be used for custom status output (such as LED's or a display) or other functionality that you want to trigger regularly even when the user isn't typing.
