** The Demo **
Not complete yet.
The demo flashes the board LED using a thread, by pressing the button located
on the board the test procedure is activated with output on the serial port
COM2 (USART2).

*****************************************************************************
*** 0.6.3 ***
- NEW: ARM Cortex-M3 port completed. The demo program targets the STM32F103
chip from ST Microelectronics on an Olimex STM32-P103 board.
- Fixed a minor error in ./ports/ARM7/vic.h, it should not affect anything.
- Minor bug fix: in chThdCreate() a working area size equal to UserStackSize(0)
was asserted as an error when in debug mode. It is now allowed.
- Increased the stack size for the threads in the test suite to 128 bytes
because THUMB/THUMB2 modes seem to use a lot more stack than ARM mode.
- More work done on the ARM-CM3 port but it does not pass the test suite yet.
*** 0.6.2 ***
- NEW: Added C++ wrapper around the ChibiOS/RT core APIs, now it is possible
