** TARGET **
The demo runs on an STM32F3 Discovery board.
The demo runs on an ST STM32F3-Discovery board.
** The Demo **
The demo uses the ChibiOS Shell in order to test L3GD20 APIs.
Shell is used on the SDU1 BaseSequentialStream.
The demo prints L3GD20 data on the SD1 BaseSequentialStream.
** Build Procedure **
The demo has been tested by using the free Codesourcery GCC-based toolchain
The demo has been tested using the free Codesourcery GCC-based toolchain
and YAGARTO.
Just modify the TRGT line in the makefile in order to use different GCC ports.
