681/1371
Function description
Pauses the DMA Transfer.
Parameters
husart: pointer to a USART_HandleTypeDef structure that
contains the configuration information for the specified
USART module.
Return values
HAL: status
HAL_USART_DMAResume
Function name
HAL_StatusTypeDef HAL_USART_DMAResume
(USART_HandleTypeDef * husart)
Function description
Resumes the DMA Transfer.
Parameters
husart: pointer to a USART_HandleTypeDef structure that
contains the configuration information for the specified
USART module.
Return values
HAL: status
HAL_USART_DMAStop
Function name
HAL_StatusTypeDef HAL_USART_DMAStop
(USART_HandleTypeDef * husart)
Function description
Stops the DMA Transfer.
Parameters
husart: pointer to a USART_HandleTypeDef structure that
contains the configuration information for the specified
USART module.
Return values
HAL: status
HAL_USART_Abort
Function name
HAL_StatusTypeDef HAL_USART_Abort
(USART_HandleTypeDef * husart)
Function description
Abort ongoing transfer (blocking mode).
Parameters
husart: USART handle.
Return values
HAL: status
Notes
This procedure could be used for aborting any ongoing
transfer (either Tx or Rx, as described by TransferType
parameter) started in Interrupt or DMA mode. This procedure
performs following operations : Disable PPP Interrupts
(depending of transfer direction)Disable the DMA transfer in
the peripheral register (if enabled)Abort DMA transfer by
calling HAL_DMA_Abort (in case of transfer in DMA
mode)Set handle State to READY
This procedure is executed in blocking mode : when exiting
function, Abort is considered as completed.
HAL_USART_Abort_IT
Function name
HAL_StatusTypeDef HAL_USART_Abort_IT
