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.

main.cpp or sketch.ino

// Playing a digital WAV recording repeatadly using the XTronical DAC Audio library
// prints out to the serial monitor numbers counting up showing that the sound plays 
// independently of the main loop
// See www.xtronical.com for write ups on sound, the hardware required and how to make
// the wav files and include them in your code
