contains the configuration information for the specified UART
module.
pData: Pointer to data buffer
Size: Amount of data to be sent
Return values
HAL: status
HAL_UART_Receive_DMA
Function name
HAL_StatusTypeDef HAL_UART_Receive_DMA
(UART_HandleTypeDef * huart, uint8_t * pData, uint16_t Size)
Function description
Receives an amount of data in non blocking mode.
Parameters
