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. |
Detailed Description
Extended UART HAL module driver. This file provides firmware functions to manage the following extended functionalities of the Universal Asynchronous Receiver Transmitter Peripheral (UART). + Initialization and de-initialization functions + Peripheral Control functions.
- Version:
- V1.1.0
- Date:
- 16-September-2015
============================================================================== ##### UART peripheral extended features ##### ============================================================================== (#) Declare a UART_HandleTypeDef handle structure. (#) For the UART RS485 Driver Enable mode, initialize the UART registers by calling the HAL_RS485Ex_Init() API.
