  * @brief  This function is used to initialize the HAL Library; it must be the first 
  *         instruction to be executed in the main program (before to call any other
  *         HAL function), it performs the following:
  *           Configure the Flash prefetch, instruction and Data caches.
  *           Configures the SysTick to generate an interrupt each 1 millisecond,
  *           which is clocked by the HSI (at this stage, the clock is not yet
  *           configured and thus the system is running from the internal HSI at 16 MHz).
  *           Set NVIC Group Priority to 4.
  *           Calls the HAL_MspInit() callback function defined in user file 
  *           "stm32f4xx_hal_msp.c" to do the global low level hardware initialization 
  *            
  * @note   SysTick is used as time base for the HAL_Delay() function, the application
  *         need to ensure that the SysTick time base is always set to 1 millisecond
  *         to have correct HAL operation.
  * @param  None
  * @retval HAL status
