Size)
Function description
Simplex Send an amount of data in non-blocking mode.
Parameters
husart: pointer to a USART_HandleTypeDef structure that
contains the configuration information for the specified
USART module.
pTxData: Pointer to data buffer
Size: Amount of data to be sent
Return values
HAL: status
HAL_USART_Receive_DMA
Function name
HAL_StatusTypeDef HAL_USART_Receive_DMA
(USART_HandleTypeDef * husart, uint8_t * pRxData, uint16_t
Size)
Function description
Full-Duplex Receive an amount of data in non-blocking mode.
Parameters
husart: pointer to a USART_HandleTypeDef structure that
contains the configuration information for the specified
USART module.
pRxData: Pointer to data buffer
Size: Amount of data to be received
Return values
HAL: status
Notes
The USART DMA transmit stream must be configured in
order to generate the clock for the slave.
When the USART parity is enabled (PCE = 1) the data
received contain the parity bit.
HAL_USART_TransmitReceive_DMA
Function name
HAL_StatusTypeDef HAL_USART_TransmitReceive_DMA
(USART_HandleTypeDef * husart, uint8_t * pTxData, uint8_t *
pRxData, uint16_t Size)
Function description
Full-Duplex Transmit Receive an amount of data in non-blocking
mode.
Parameters

contains the configuration information for the specified
USART module.
pTxData: Pointer to data transmitted buffer
pRxData: Pointer to data received buffer
Size: Amount of data to be received
Return values
HAL: status
Notes
When the USART parity is enabled (PCE = 1) the data
received contain the parity bit.
