Functions

static void UARTEx_Wakeup_AddressConfig (UART_HandleTypeDef *huart, UART_WakeUpTypeDef WakeUpSelection)
 Initialize the UART wake-up from stop mode parameters when triggered by address detection.
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.
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_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.
__weak void HAL_UARTEx_WakeupCallback (UART_HandleTypeDef *huart)
 UART wakeup from Stop mode callback.
