# esp-adf (esp-idf) audio_hal component for AI-Thinker's ESP32-A1S module (AC101 codec)
This is a *audio_hal* component for AI-Thinker's *ESP32-A1S* [1] module
respectively *ESP32 Audio Kit* [2]. The audio_hal component shipped with the
esp-adf [3] unfortunately doesn't provide any interface to add third-party
codec. This is based on AI-Thinker's code [4], which is an esp-adf fork with
modifications for this codec (AC101).
How to use:
Clone this repository into *components/audio_hal* of your esp-adf project:
```
cd /path/to/your/project
git clone https://github.com/phkehl/esp32-a1s-audio_hal.git components/audio_hal
```
Or add it as a git submodule:
```
cd /path/to/your/project
git submodule add -b master https://github.com/phkehl/esp32-a1s-audio_hal.git components/audio_hal
```
This will then take precedence over the one in *$ADF_PATH/components/audio_hal*.
The modifications to *audio_hal.h* and *audio_hal.h* are very minimal and
upgrading this with later versions of the esp-adf should be easy. There is one
additional function *esp_err_t audio_hal_pa_power(bool enable)* not present in
the original code. Use this to controls the power of the power amplifier on AI's
*ESP32 Audio Kit* board.
There is an example in the *example* subdirectory. Note the symlink
*example/components/audio_hal*.
Happy hacking!
