Function name
HAL_StatusTypeDef HAL_USART_Transmit_IT
(USART_HandleTypeDef * husart, uint8_t * pTxData, uint16_t
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
Notes
The USART errors are not managed to avoid the overrun
error.
