+# APA102 Driver {#apa102-driver}
+
+This driver provides support for APA102 addressable RGB LEDs. They are similar to the [WS2812](ws2812) LEDs, but have increased data and refresh rates.
+
+## Usage {#usage}
+
+In most cases, the APA102 driver code is automatically included if you are using either the [RGBLight](../features/rgblight) or [RGB Matrix](../features/rgb_matrix) feature with the `apa102` driver set, and you would use those APIs instead.
+
+However, if you need to use the driver standalone, add the following to your `rules.mk`:
+
+```make
+APA102_DRIVER_REQUIRED = yes
+```
+
+You can then call the APA102 API by including `apa102.h` in your code.
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define                     |Default      |Description                                                       |
+|---------------------------|-------------|------------------------------------------------------------------|
+|`APA102_DI_PIN`            |*Not defined*|The GPIO pin connected to the DI pin of the first LED in the chain|
+|`APA102_CI_PIN`            |*Not defined*|The GPIO pin connected to the CI pin of the first LED in the chain|
+|`APA102_DEFAULT_BRIGHTNESS`|`31`         |The default global brightness level of the LEDs, from 0 to 31     |
+
+## API {#api}
+
+### `void apa102_setleds(rgb_led_t *start_led, uint16_t num_leds)`
+
+Send RGB data to the APA102 LED chain.

+#### Arguments {#api-apa102-setleds-arguments}
+
+ - `rgb_led_t *start_led`  
+   A pointer to the LED array.
+ - `uint16_t num_leds`  
+   The length of the LED array.
+
+---
+
+### `void apa102_set_brightness(uint8_t brightness)`
+
+Set the global brightness.
+
+#### Arguments {#api-apa102-set-brightness-arguments}
+
+ - `uint8_t brightness`  
+   The brightness level to set, from 0 to 31.
