@par Application Description

This directory contains a set of source files that implement a simple "acceleration" 
application based on STemWin for STM32F4xx devices.

The application shows the capability of STemWin to do animations using the DMA2D HW for the 
acceleration of different draws (Bitmaps, Memdevs, ColorFill...).

Note that the following user files may need to be updated:
  LCDConf_stm324x9i_eval_MB1046.c
  LCDConf_stm324x9i_eval_MB1063.c
  GUIConf.c
(if for example more GUI allocated memory is needed)

 How to interact with the application
 ------------------------------------
 - The application is an automatic run of a FadeIn/FadeOut between different plans.
 - After the run of these plans, the performance of the operations done is displayed on the screen
 - It will loop infinetly.  

@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.
