A Simple SdFat Audio Player
The example demonstrates how to implement an MP3 Player: which provides the data from a SD drive and provides the audio via A2DP (e.g. to a Bluetooth Speaker): The AudioSourceSdFat class builds on the SdFat Library from Bill Greiman which provides FAT16/FAT32 and exFAT support.
