Firmware architecture

The demonstration is built with a modular architecture based on a real time operating
system and uses a graphical windowing system based on the uC-OSII RTOS from Micrium
and the emWin graphical stack from Segger.
The system configuration and the standard peripheral settings and configuration are made
through the STM32F2xx Standard Peripheral Library.
Data used by the application is stored in the external USB Flash disk through a FAT file
system (emFile from Segger) in order to save space in the STM32 internal Flash memory.
