DESCRIPTION
===========
This example project shows how to use the IAR Embedded Workbench for ARM
to develop code for the IAR STM32-SK evaluation boards and MOD-MP3 module.
It implements a MP3 player. The MOD-MP3 module must be connected to the
UEXT connector of the IAR STM32-SK board. The player can read MMC/SD media
formatting under FAT12/16/32 file system.

COMPATIBILITY
=============
The project is compatible with the IAR IAR STM32-SK evaluation board and MOD-MP3
module.

The project is by default configured to use the J-Link JTAG interface.

CONFIGURATION
=============
The application is downloaded to the flash.

Jumpers:
PWR_SEL - depending of power source

Buttons:
B1 - Next a file/dir (select mode)
B1 - Sound effects None, Wide Stereo, Loudness (play mode)
B2 - Enter/exit form directory or Play/Stop
Potentiometers:
AN_TR - volume control

GETTING STARTED
===============
1) Start the IAR Embedded Workbench for ARM.

2) Select File->Open->Workspace...
Open the following workspace:

installation-root>\arm\examples\ST\STM32F10x\
IAR-STM32-SK\MP3_player\MP3_player.eww

3) Run the program.
