Functions
HAL_StatusTypeDef	HAL_RS485Ex_Init (UART_HandleTypeDef *huart, uint32_t Polarity, uint32_t AssertionTime, uint32_t DeassertionTime)
	Initialize the RS485 Driver enable feature according to the specified parameters in the UART_InitTypeDef and creates the associated handle.
__weak void	HAL_UARTEx_WakeupCallback (UART_HandleTypeDef *huart)
	UART wakeup from Stop mode callback.
HAL_StatusTypeDef	HAL_UARTEx_StopModeWakeUpSourceConfig (UART_HandleTypeDef *huart, UART_WakeUpTypeDef WakeUpSelection)
	Set Wakeup from Stop mode interrupt flag selection.
HAL_StatusTypeDef	HAL_UARTEx_EnableStopMode (UART_HandleTypeDef *huart)
	Enable UART Stop Mode.
HAL_StatusTypeDef	HAL_UARTEx_DisableStopMode (UART_HandleTypeDef *huart)
	Disable UART Stop Mode.
HAL_StatusTypeDef	HAL_UARTEx_EnableClockStopMode (UART_HandleTypeDef *huart)
	Keep UART Clock enabled when in Stop Mode.
HAL_StatusTypeDef	HAL_UARTEx_DisableClockStopMode (UART_HandleTypeDef *huart)
	Disable UART Clock when in Stop Mode.
HAL_StatusTypeDef	HAL_MultiProcessorEx_AddressLength_Set (UART_HandleTypeDef *huart, uint32_t AddressLength)
	By default in multiprocessor mode, when the wake up method is set to address mark, the UART handles only 4-bit long addresses detection; this API allows to enable longer addresses detection (6-, 7- or 8-bit long).
HAL_StatusTypeDef	HAL_UARTEx_ReceiveToIdle (UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size, uint16_t *RxLen, uint32_t Timeout)
	Receive an amount of data in blocking mode till either the expected number of data is received or an IDLE event occurs.
HAL_StatusTypeDef	HAL_UARTEx_ReceiveToIdle_IT (UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size)
	Receive an amount of data in interrupt mode till either the expected number of data is received or an IDLE event occurs.
HAL_StatusTypeDef	HAL_UARTEx_ReceiveToIdle_DMA (UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size)
	Receive an amount of data in DMA mode till either the expected number of data is received or an IDLE event occurs.
