########################################################################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 controlGETTING 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.
