** TARGET **

The demo runs on an STM32L4 Discovery board.

** The Demo **

The demo flashes the board LED using a thread, read data from L3GD20 printing
it on a BaseSequentialStream (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.
