* 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 STM32F4xx 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"
