                       ##### How to use this driver #####
  ======================================================================================================================


    [..]
      DMA transfer modes are divided to 2 major categories :
          (+) Normal transfers (legacy)
          (+) Linked-list transfers

    [..]
      Normal transfers mode is initialized via the standard module and linked-list mode is configured via the extended
      module.

    [..]
      Additionally to linked-list capability, all advanced DMA features are managed and configured via the extended
      module as extensions to normal mode.
      Advanced features are :
          (+) Repeated block feature.
          (+) Trigger feature.
          (+) Data handling feature.

    [..]
      DMA Legacy circular transfer, is replaced by circular linked-list configuration.


    *** Initialization and De-Initialization ***
    ============================================
    [..]
      For a given channel, enable and configure the peripheral to be connected to the DMA Channel (except for internal
      SRAM/FLASH memories: no initialization is necessary) please refer to Reference manual for connection between
      peripherals and DMA requests.

    [..]
      For a given channel, use HAL_DMA_Init function to program the required configuration for normal transfer through
      the following parameters:

          (+) Request               : Specifies the DMA channel request
              Request parameters    :
              (++) can be a value of DMA_Request_Selection

          (+) BlkHWRequest          : Specifies the Block hardware request mode for DMA channel
              (++) can be a value of DMA_Block_Request

          (+) Direction             : Specifies the transfer direction for DMA channel
              (++) can be a value of DMA_Transfer_Direction

          (+) SrcInc                : Specifies the source increment mode for the DMA channel
              (++) can be a value of DMA_Source_Increment_Mode

          (+) DestInc               : Specifies the destination increment mode for the DMA channel
              (++) can be a value of DMA_Destination_Increment_Mode

          (+) SrcDataWidth          : Specifies the source data width for the DMA channel
              (++) can be a value of DMA_Source_Data_Width

          (+) DestDataWidth         : Specifies the destination data width for the DMA channel
              (++) can be a value of DMA_Destination_Data_Width

          (+) Priority              : Specifies the priority for the DMA channel
              (++) can be a value of DMA_Priority_Level

          (+) SrcBurstLength        : Specifies the source burst length (number of beats) for the DMA channel
              (++) can be a value of between 1 and 64

          (+) DestBurstLength       : Specifies the destination burst length (number of beats) for the DMA channel
              (++) can be a value of between 1 and 64

          (+) TransferAllocatedPort : Specifies the source and destination allocated ports
              (++) can be a value of DMA_Transfer_Allocated_Port

          (+) TransferEventMode     : Specifies the transfer event mode for the DMA channel
              (++) can be a value of DMA_Transfer_Event_Mode

          (+) Mode                  : Specifies the transfer mode for the DMA channel
              (++) can be one of the following modes :
                  (+++) DMA_NORMAL : Normal Mode
                  (+++) DMA_PFCTRL : Peripheral Flow Control (peripheral early termination) Mode

    *** Polling mode IO operation ***
    =================================
    [..]
          (+) Use HAL_DMA_Start() to start a DMA normal transfer after the configuration of source address, destination
              address and the size of data to be transferred.

          (+) Use HAL_DMA_PollForTransfer() to poll for selected transfer level. In this case a fixed Timeout can be
              configured by User depending on his application.
              Transfer level can be :
              (++) HAL_DMA_HALF_TRANSFER
              (++) HAL_DMA_FULL_TRANSFER
              For circular transfer, this API returns an HAL_ERROR with HAL_DMA_ERROR_NOT_SUPPORTED error code.

          (+) Use HAL_DMA_Abort() function to abort any ongoing DMA transfer in blocking mode.
              This API returns HAL_ERROR when there is no ongoing transfer or timeout is reached when disabling the DMA
              channel. (This API should not be called from an interrupt service routine)


    *** Interrupt mode IO operation ***
    ===================================
    [..]
          (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()

          (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()

          (+) Use HAL_DMA_RegisterCallback() function to register user callbacks from the following list :
              (++) XferCpltCallback     : transfer complete callback.
              (++) XferHalfCpltCallback : half transfer complete callback.
              (++) XferErrorCallback    : transfer error callback.
              (++) XferAbortCallback    : transfer abort complete callback.
              (++) XferSuspendCallback  : transfer suspend complete callback.

          (+) Use HAL_DMA_Start_IT() to start the DMA transfer after the enable of DMA interrupts and the configuration
              of source address,destination address and the size of data to be transferred.

          (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() interrupt subroutine to handle any DMA interrupt.

          (+) Use HAL_DMA_Abort_IT() function to abort any on-going DMA transfer in non-blocking mode.
              This API will suspend immediately the DMA channel execution. When the transfer is effectively suspended,
              an interrupt is generated and HAL_DMA_IRQHandler() will reset the channel and execute the callback
              XferAbortCallback. (This API could be called from an interrupt service routine)


    *** State and errors ***
    ========================
    [..]
          (+) Use HAL_DMA_GetState() function to get the DMA state.
          (+) Use HAL_DMA_GetError() function to get the DMA error code.


    *** Security and privilege attributes ***
    =========================================
    [..]
          (+) Use HAL_DMA_ConfigChannelAttributes() function to configure DMA channel security and privilege attributes.
              (++) Security  : at channel level, at source level and at destination level.
              (++) Privilege : at channel level.
          (+) Use HAL_DMA_GetConfigChannelAttributes() function to get the DMA channel attributes.
          (+) Use HAL_DMA_LockChannelAttributes() function to lock the DMA channel security and privilege attributes
              configuration. This API can be called once after each system boot.
              If called again, HAL_DMA_ConfigChannelAttributes() API has no effect.
              Unlock is done either by a system boot or a by an RCC reset.
          (+) Use HAL_DMA_GetLockChannelAttributes() function to get the attributes lock status.


    *** DMA HAL driver macros list ***
    ==================================
    [..]
      Below the list of most used macros in DMA HAL driver.

          (+) __HAL_DMA_ENABLE        : Enable the specified DMA Channel.
          (+) __HAL_DMA_DISABLE       : Disable the specified DMA Channel.
          (+) __HAL_DMA_GET_FLAG      : Get the DMA Channel pending flags.
          (+) __HAL_DMA_CLEAR_FLAG    : Clear the DMA Channel pending flags.
          (+) __HAL_DMA_ENABLE_IT     : Enable the specified DMA Channel interrupts.
          (+) __HAL_DMA_DISABLE_IT    : Disable the specified DMA Channel interrupts.
          (+) __HAL_DMA_GET_IT_SOURCE : Check whether the specified DMA Channel interrupt has occurred or not.

    [..]
     (@) You can refer to the header file of the DMA HAL driver for more useful macros.
