@par Example Description

  This example provides a description of how to configure the DMA2D peripheral in 
  Memory_to_Memory transfer mode and display the result on LCD, in resorting to
  DMA2D LL APIs for performance improvement.

  The source buffer in format RGB565 and size 128x160 located in Flash is copied 
  in Memory to Memory mode by the DMA2D to the LCD. 
  
  In this basic example, the goal is to show how to set some of the DMA2D IP
  parameters thru DMAD LL APIs:
  - input and output image format, alpha value
  - origin and destination buffers addresses
  - transfer size
  - DMA2D interruptions enabling
  - DMA2D transfer start 
  
  STM32F429ZI-Nucleo Rev B board's LEDs can be used to monitor the transfer status:
 - LED1 is ON when the DMA2D transfer is complete.
 - LED2 is ON when there is a DMA2D transfer error.
 - LED3 is ON if the adafruit shield is not detected.
 

@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 devices.
  
  - This example has been tested with STMicroelectronics STM32F429ZI-Nucleo Rev B 
    board and can be easily tailored to any other supported device 
    and development board. 

  - Adafruit 1.8" TFT shield must be connected on CN7, CN8, CN9 and CN10 Arduino connectors,
    for more details please refer to UM1726.
