+*****************************************************************************

+** ChibiOS/RT + FatFS demo for SAM7.                                    **

+*****************************************************************************

+

+** TARGET **

+

+The demo runs on an Olimex SAM-EX256 board. The port on other boards or other

+members of the SAM7 family should be an easy task.

+

+** The Demo **

+

+This demo shows how to integrate the FatFs file system and use the SPI and MMC

+drivers.

+The demo flashes the board LCD background using a thread and monitors the MMC

+slot for a card insertion. When a card is inserted then the file system is

+mounted and the LCD background flashes faster.

+A command line shell is spawned on SD1, all the interaction with the demo is

+performed using the command shell, type "help" for a list of the available

+commands.

+

+** Build Procedure **

+

+The demo was built using the YAGARTO toolchain but any toolchain based on GCC

+and GNU userspace programs will work.
