Decoding a MP3 file
In this example we decode a MP3 file into RAW output and send it the analog output pins.
Currently we provide multiple mp3 decoders
- libhelix
- tinymp3
Unfortunately non of those are currently stable in all environments....
Output Device: Piezo Electric Element
To test the output I am using piezo electric elements
It should also be possible to connect a headphone to the output pins.
