+** ChibiOS/RT port for ARM7TDMI LPC214X using G++. **
+*****************************************************************************
+
+** 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 implemented
+as C++ classes. Pressing both buttons activates the test procedure on the
+serial port 1.
+
+NOTE: the C++ GNU compiler can produce code sizes comparable to C if you
+ don't use RTTI and standard libraries, those are disabled by default
+ in the makefile. You can enable them if you have a lot of program space
+ available. It is possible to use a lot of C++ features without using
+ runtimes, just see the demo.
+
+** Build Procedure **
+
+The demo was built using the YAGARTO toolchain but any toolchain based on GCC
+and GNU userspace programs will work.
