@par Example Description

This project provides a reference template that can be used to build any firmware application.

This directory provides a reference template project that can be used to build any firmware application for
STM32F429xx/439xx devices using STM32CubeF4 HAL and running on STM324x9I-EVAL board from STMicroelectronics. 

Two workspace are provided for STM32429I-EVAL (STM32F429xx devices) and STM32439I-EVAL (STM32F439xx devices)
configuration: the difference is related to the hardware Cryptographic and Hash processors which are available
only in STM32F439xx devices.
Each workspace include the right set of peripherals, linker and startup files.


@note Care must be taken when using HAL_Delay(), this function provides accurate delay (in milliseconds)
      based on variable incremented in SysTick ISR. This implies that if HAL_Delay() is called from
      a peripheral ISR process, then the SysTick interrupt must have higher priority (numerically lower)
      than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
      To change the SysTick interrupt priority you have to use HAL_NVIC_SetPriority() function.
      
@note The application needs to ensure that the SysTick time base is always set to 1 millisecond
      to have correct HAL operation.

@par Hardware and Software environment  

  - This example runs on STM32F429xx/STM32F439xx devices.
    
  - This example has been tested with STMicroelectronics STM324x9I-EVAL RevB 
    evaluation boards and can be easily tailored to any other supported device 
    and development board.


@par How to use it ? 

In order to make the program work, you must do the following :
 - Open your preferred toolchain 
 - Rebuild all files and load your image into target memory
 - Run the example
