*****************************************************************************
** ChibiOS/RT port for ARM-Cortex-M4 STM32L476. **
*****************************************************************************
** TARGET **
The demo runs on an ST_NUCLEO_L476RG board.
** The Demo **
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
SD2 (USART2, mapped on USB virtual COM port).
** Build Procedure **
The demo has been tested by using the free Codesourcery GCC-based toolchain
and YAGARTO.
Just modify the TRGT line in the makefile in order to use different GCC ports.
** Notes **
Some files used by the demo are not part of ChibiOS/RT but are copyright of
ST Microelectronics and are licensed under a different license.
Also note that not all the files present in the ST library are distributed
with ChibiOS/RT, you can find the whole library on the ST web site:
