*****************************************************************************
** ChibiOS/RT + FatFS demo for LPC214x. **
*****************************************************************************
** TARGET **
The demo runs on an Olimex LPC-P2148 board. The port on other boards or other
members of the LPC2000 family should be an easy task.
** The Demo **
The demo blinks the leds on the board by using multiple threads.
By pressing button 1 a directory scan on the MMC slot is performed, by
pressing the button 2 the test suite is activated on serial port 1.
** Build Procedure **
The demo was built using the YAGARTO toolchain but any toolchain based on GCC
and GNU userspace programs will work.
