******************************************************************************
* @file STM32F4xx_IAP/src/menu.c
* @author MCD Application Team
* @version V1.0.0
* @date 10-October-2011
* @brief This file provides the software which contains the main menu routine.
* The main menu gives the options of:
* - downloading a new binary file,
* - uploading internal flash memory,
* - executing the binary file already loaded
* - disabling the write protection of the Flash sectors where the
* user loads his binary file.
