** TARGET **
The demo runs on both Olimex STM32-E407 or STM32F4-Discovery boards, just
change the board reference in the Makefile.
The demo runs on an STM32F407 Discovery board REV C or later.
** The Demo **
The application demonstrates the use of the STM32 USB (OTG) driver.
The application demonstrates the use of the STM32F4xx SPI driver in order
to acquire data from LIS3DSH using ChibiOS/EX.
