 ## API {#api}
 
-### `void ws2812_setleds(rgb_led_t *ledarray, uint16_t number_of_leds)` {#api-ws2812-setleds}
+### `void ws2812_init(void)` {#api-ws2812-init}
 
-Send RGB data to the WS2812 LED chain.
+Initialize the LED driver. This function should be called first.
 
-#### Arguments {#api-ws2812-setleds-arguments}
+---
 
- - `rgb_led_t *ledarray`  
-   A pointer to the LED array.
- - `uint16_t number_of_leds`  
-   The length of the LED array.
+### `void ws2812_set_color(int index, uint8_t red, uint8_t green, uint8_t blue)` {#api-ws2812-set-color}
+
+Set the color of a single LED. This function does not immediately update the LEDs; call `ws2812_flush()` after you are finished.
+
+#### Arguments {#api-ws2812-set-color-arguments}
+
+ - `int index`  
+   The LED index in the WS2812 chain.
+ - `uint8_t red`  
+   The red value to set.
+ - `uint8_t green`  
+   The green value to set.
+ - `uint8_t blue`  
+   The blue value to set.
+
+---
+
+### `void ws812_set_color_all(uint8_t red, uint8_t green, uint8_t blue)` {#api-ws2812-set-color-all}
+
+Set the color of all LEDs.
+
+#### Arguments {#api-ws2812-set-color-all-arguments}
+
+ - `uint8_t red`  
+   The red value to set.
+ - `uint8_t green`  
+   The green value to set.
+ - `uint8_t blue`  
+   The blue value to set.
+
+---
+
+### `void ws2812_flush(void)` {#api-ws2812-flush}
+
+Flush the PWM values to the LED chain.
