A minimalistic stereo music player.

This application needs two speakers, one connected to DAC0 and the other to DAC1, and a SD card with songs in the root folder. The format of the songs must be the expected format by the DAC hardware. For Arduino Due, one 12 bits sample for each channel tagged with the channel number in the 13th bit are packed into a 32 bits number. Use music_player.py to convert uncompressed wav or mp3 files to this format.

Example shell commands to list, play, pause, resume and stop songs.

All mp3-files in the folder songs can be converted to the .b12-format with the command 'make convert'. Copy the creted .b12 files to a SD card and insert it into the music player.
