Andreas Grün / Mbed 2 deprecated madplayer

MP3 Player without external hardware MP3 Player without external hardware. A software based MP3 player based on a modified version of libmad. Mono output (at the moment) via AnalogOut. Files are read from an USB drive. This is a demo program, it plays only one file at the moment. Documentation is in "main.cpp" and "config.h"

USBHostLite/usbhost_lpc17xx.h@2:f28cf0afd021, 2010-11-27 (annotated)

Revision:
2:f28cf0afd021
Parent:
0:7627c79db971 
Version 3:

 * moved another memory block into AHB RAM, giving more room for

 * stereo buffer.

 * moved content of decode() to main()

 * decoding	is now safe to be called multiple times (bug in older versions)

 * Output routine now fills stereo buffer, DAC output sums channels,

 * just for demonstration that stereo output could go here
