+  *          The file is the unique include file that the application programmer
+  *          is using in the C source code, usually in main.c. This file contains:
+  *           - Configuration section that allows to select:
+  *              - The STM32F2xx device used in the target application
+  *              - To use or not the peripheral’s drivers in application code(i.e. 
+  *                code will be based on direct access to peripheral’s registers 
+  *                rather than drivers API), this option is controlled by 
+  *                "#define USE_HAL_DRIVER"
