*****************************************************************************
** ChibiOS/RT port for ARM7TDMI 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 **
This is a minimal demo, it just blinks the leds on the board by using multiple
threads, most subsystems are disabled.
** Build Procedure **
The demo was built using the YAGARTO toolchain but any toolchain based on GCC
and GNU userspace programs will work.
