XTronical_XT_DAC_Audio_Mirror

Mirror of XTronical's excellent XT_DAC_Audio library for ease of integration into platformio projects

XTronical, if you're reading this, please consider uploading your projects/this library to your personal git. I have mirrored this for personal convenience.

// Playing a digital WAV recording repeatadly using the XTronical DAC Audio library

// independently of the main loop

// the wav files and include them in your code
