HAL_DMA_Start_IT
Function name
HAL_StatusTypeDef HAL_DMA_Start_IT
(DMA_HandleTypeDef * hdma, uint32_t SrcAddress, uint32_t
DstAddress, uint32_t DataLength)
Function description
Start the DMA Transfer with interrupt enabled.
Parameters
hdma: pointer to a DMA_HandleTypeDef structure that
contains the configuration information for the specified DMA
Stream.
SrcAddress: The source memory Buffer address
DstAddress: The destination memory Buffer address
DataLength: The length of data to be transferred from
source to destination
Return values
HAL: status
HAL_DMA_Abort
Function name
HAL_StatusTypeDef HAL_DMA_Abort (DMA_HandleTypeDef *
hdma)
Function description
Aborts the DMA Transfer.
Parameters
hdma: : pointer to a DMA_HandleTypeDef structure that
contains the configuration information for the specified DMA
Stream.
Return values
HAL: status
Notes
After disabling a DMA Stream, a check for wait until the DMA
Stream is effectively disabled is added. If a Stream is disabled
while a data transfer is ongoing, the current data will be
transferred and the Stream will be effectively disabled only
after the transfer of this single data is finished.
HAL_DMA_Abort_IT
Function name
HAL_StatusTypeDef HAL_DMA_Abort_IT

Function description
Aborts the DMA Transfer in Interrupt mode.
Parameters
hdma: : pointer to a DMA_HandleTypeDef structure that
contains the configuration information for the specified DMA
Stream.
Return values
HAL: status
HAL_DMA_PollForTransfer
Function name
HAL_StatusTypeDef HAL_DMA_PollForTransfer
(DMA_HandleTypeDef * hdma,
HAL_DMA_LevelCompleteTypeDef CompleteLevel, uint32_t
Timeout)
Function description
Polling for transfer complete.
Parameters
hdma: pointer to a DMA_HandleTypeDef structure that
