+ * + Peripheral Control functions
+ * + Peripheral State and Errors functions

+ @verbatim
+ ==============================================================================
+ ##### 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 calls 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 ***
+ =============================================
+ [..]
+ Below the list of most used macros in DMA2D HAL driver :
+
+ (+) __HAL_DMA2D_ENABLE: Enable the DMA2D peripheral.
+ (+) __HAL_DMA2D_GET_FLAG: Get the DMA2D pending flags.
+ (+) __HAL_DMA2D_CLEAR_FLAG: Clear the DMA2D pending flags.
+ (+) __HAL_DMA2D_ENABLE_IT: Enable the specified DMA2D interrupts.
+ (+) __HAL_DMA2D_DISABLE_IT: Disable the specified DMA2D interrupts.
+ (+) __HAL_DMA2D_GET_IT_SOURCE: Check whether the specified DMA2D interrupt is enabled or not.
+
+ *** Callback registration ***
+ ===================================
+ [..]
+ (#) The compilation define USE_HAL_DMA2D_REGISTER_CALLBACKS when set to 1
+ allows the user to configure dynamically the driver callbacks.
+ Use function @ref HAL_DMA2D_RegisterCallback() to register a user callback.
+
+ (#) Function @ref HAL_DMA2D_RegisterCallback() allows to register following callbacks:
+ (+) XferCpltCallback : callback for transfer complete.
+ (+) XferErrorCallback : callback for transfer error.
+ (+) LineEventCallback : callback for line event.
+ (+) CLUTLoadingCpltCallback : callback for CLUT loading completion.
+ (+) MspInitCallback : DMA2D MspInit.
+ (+) MspDeInitCallback : DMA2D MspDeInit.
+ This function takes as parameters the HAL peripheral handle, the Callback ID
+ and a pointer to the user callback function.
+
+ (#) Use function @ref HAL_DMA2D_UnRegisterCallback() to reset a callback to the default
+ weak (surcharged) function.
+ @ref HAL_DMA2D_UnRegisterCallback() takes as parameters the HAL peripheral handle,
+ and the Callback ID.
+ This function allows to reset following callbacks:
+ (+) XferCpltCallback : callback for transfer complete.
+ (+) XferErrorCallback : callback for transfer error.
+ (+) LineEventCallback : callback for line event.
+ (+) CLUTLoadingCpltCallback : callback for CLUT loading completion.
+ (+) MspInitCallback : DMA2D MspInit.
+ (+) MspDeInitCallback : DMA2D MspDeInit.
+
+ (#) By default, after the @ref HAL_DMA2D_Init and if the state is HAL_DMA2D_STATE_RESET
+ all callbacks are reset to the corresponding legacy weak (surcharged) functions:
+ examples @ref HAL_DMA2D_LineEventCallback(), @ref HAL_DMA2D_CLUTLoadingCpltCallback()
+ Exception done for MspInit and MspDeInit callbacks that are respectively
+ reset to the legacy weak (surcharged) functions in the @ref HAL_DMA2D_Init
+ and @ref HAL_DMA2D_DeInit only when these callbacks are null (not registered beforehand)
+ If not, MspInit or MspDeInit are not null, the @ref HAL_DMA2D_Init and @ref HAL_DMA2D_DeInit
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
+
+ Exception as well for Transfer Completion and Transfer Error callbacks that are not defined
+ as weak (surcharged) functions. They must be defined by the user to be resorted to.
+
+ Callbacks can be registered/unregistered in READY state only.
+ Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
+ in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
+ during the Init/DeInit.
+ In that case first register the MspInit/MspDeInit user callbacks
+ using @ref HAL_DMA2D_RegisterCallback before calling @ref HAL_DMA2D_DeInit
+ or @ref HAL_DMA2D_Init function.
+
+ When The compilation define USE_HAL_DMA2D_REGISTER_CALLBACKS is set to 0 or
+ not defined, the callback registering feature is not available
+ and weak (surcharged) callbacks are used.
+
