  ==============================================================================
                        ##### How to use this driver #####
  ==============================================================================
    [..]
      (#) Program the required configuration through the following parameters:   
          the transfer mode, the output color mode and the output offset using 
          HAL_DMA2D_Init() function.

      (#) Program the required configuration through the following parameters:   
          the input color mode, the input color, the input alpha value, the alpha mode,
          the red/blue swap mode, the inverted alpha mode and the input offset using 
          HAL_DMA2D_ConfigLayer() function for foreground or/and background layer.
          
     *** Polling mode IO operation ***
     =================================   
    [..]        
       (#) Configure pdata parameter (explained hereafter), destination and data length 
           and enable the transfer using HAL_DMA2D_Start(). 
       (#) Wait for end of transfer using HAL_DMA2D_PollForTransfer(), at this stage
           user can specify the value of timeout according to his end application.
               
     *** Interrupt mode IO operation ***    
     ===================================
     [..] 
       (#) Configure pdata parameter, destination and data length and enable 
           the transfer using HAL_DMA2D_Start_IT(). 
       (#) Use HAL_DMA2D_IRQHandler() called under DMA2D_IRQHandler() interrupt subroutine.
       (#) At the end of data transfer HAL_DMA2D_IRQHandler() function is executed and user can 
           add his own function by customization of function pointer XferCpltCallback (member 
           of DMA2D handle structure). 
       (#) In case of error, the HAL_DMA2D_IRQHandler() function will call the callback 
           XferErrorCallback.            

         -@-   In Register-to-Memory transfer mode, pdata parameter is the register
               color, in Memory-to-memory or Memory-to-Memory with pixel format
               conversion pdata is the source address.

         -@-   Configure the foreground source address, the background source address, 
               the destination and data length then Enable the transfer using 
               HAL_DMA2D_BlendingStart() in polling mode and HAL_DMA2D_BlendingStart_IT()
               in interrupt mode.
               
         -@-   HAL_DMA2D_BlendingStart() and HAL_DMA2D_BlendingStart_IT() functions
               are used if the memory to memory with blending transfer mode is selected.
                   
      (#) Optionally, configure and enable the CLUT using HAL_DMA2D_CLUTLoad() in polling
          mode or HAL_DMA2D_CLUTLoad_IT() in interrupt mode.

      (#) Optionally, configure the line watermark in using the API HAL_DMA2D_ProgramLineEvent()
          
      (#) Optionally, configure the dead time value in the AHB clock cycle inserted between two 
          consecutive accesses on the AHB master port in using the API HAL_DMA2D_ConfigDeadTime()
          and enable/disable the functionality  with the APIs HAL_DMA2D_EnableDeadTime() or
          HAL_DMA2D_DisableDeadTime().          
   
      (#) The transfer can be suspended, resumed and aborted using the following
          functions: HAL_DMA2D_Suspend(), HAL_DMA2D_Resume(), HAL_DMA2D_Abort().
          
      (#) The CLUT loading can be suspended, resumed and aborted using the following
          functions: HAL_DMA2D_CLUTLoading_Suspend(), HAL_DMA2D_CLUTLoading_Resume(), 
          HAL_DMA2D_CLUTLoading_Abort().                
                     
      (#) To control the DMA2D state, use the following function: HAL_DMA2D_GetState().   
      
      (#) To read the DMA2D error code, use the following function: HAL_DMA2D_GetError().                         

     *** DMA2D HAL driver macros list ***
