USB host audio example application using SD Card FAT file system


This example application demonstrates playing .wav files from an SD card
that is formatted with a FAT file system using USB host audio class.  The
application can browse the file system on the SD card and displays
all files that are found.  Files can be selected to show their format and
then played if the application determines that they are a valid .wav file.
Only PCM format (uncompressed) files may be played.

For additional details about FatFs, see the following site:

The application can be recompiled to run using and external USB phy to
implement a high speed host using an external USB phy.  To use the external
phy the application must be built with \b USE_ULPI defined.  This disables
the internal phy and the connector on the DK-TM4C129X board and enables the
connections to the external ULPI phy pins on the DK-TM4C129X board.
