HAL_UART_DMAStop
Function name
HAL_StatusTypeDef HAL_UART_DMAStop
(UART_HandleTypeDef * huart)
Function description
Stops the DMA Transfer.
Parameters
huart: pointer to a UART_HandleTypeDef structure that
contains the configuration information for the specified UART
module.
Return values
HAL: status
HAL_UART_Abort
Function name
HAL_StatusTypeDef HAL_UART_Abort
(UART_HandleTypeDef * huart)
Function description
Abort ongoing transfers (blocking mode).
Parameters
huart: UART handle.
Return values
HAL: status
Notes
This procedure could be used for aborting any ongoing
transfer started in Interrupt or DMA mode. This procedure
performs following operations : Disable PPP InterruptsDisable
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_UART_AbortTransmit
Function name
HAL_StatusTypeDef HAL_UART_AbortTransmit
(UART_HandleTypeDef * huart)
Function description
Abort ongoing Transmit transfer (blocking mode).
Parameters
huart: UART handle.
Return values
HAL: status

HAL_UART_AbortReceive
Function name
HAL_StatusTypeDef HAL_UART_AbortReceive
(UART_HandleTypeDef * huart)
Function description
Abort ongoing Receive transfer (blocking mode).
