=============================================================================== + ##### How to use this driver ##### + =============================================================================== + [..] + The UART HAL driver can be used as follows: + + (#) Declare a UART_HandleTypeDef handle structure (eg. UART_HandleTypeDef huart). + (#) Initialize the UART low level resources by implementing the HAL_UART_MspInit() API: + (++) Enable the USARTx interface clock. + (++) UART pins configuration: + (+++) Enable the clock for the UART GPIOs. + (+++) Configure these UART pins as alternate function pull-up. + (++) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT() + and HAL_UART_Receive_IT() APIs): + (+++) Configure the USARTx interrupt priority. + (+++) Enable the NVIC USART IRQ handle. + (++) UART interrupts handling: + -@@- The specific UART interrupts (Transmission complete interrupt, + RXNE interrupt, RX/TX FIFOs related interrupts and Error Interrupts) + are managed using the macros __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() + inside the transmit and receive processes. + (++) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA() + and HAL_UART_Receive_DMA() APIs): + (+++) Declare a DMA handle structure for the Tx/Rx channel. + (+++) Enable the DMAx interface clock. + (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters. + (+++) Configure the DMA Tx/Rx channel. + (+++) Associate the initialized DMA handle to the UART DMA Tx/Rx handle. + (+++) Configure the priority and enable the NVIC for the transfer complete + interrupt on the DMA Tx/Rx channel. + + (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Prescaler value , Hardware + flow control and Mode (Receiver/Transmitter) in the huart handle Init structure. + + (#) If required, program UART advanced features (TX/RX pins swap, auto Baud rate detection,...) + in the huart handle AdvancedInit structure. + + (#) For the UART asynchronous mode, initialize the UART registers by calling + the HAL_UART_Init() API. + + (#) For the UART Half duplex mode, initialize the UART registers by calling + the HAL_HalfDuplex_Init() API. + + (#) For the UART LIN (Local Interconnection Network) mode, initialize the UART registers + by calling the HAL_LIN_Init() API. + + (#) For the UART Multiprocessor mode, initialize the UART registers + by calling the HAL_MultiProcessor_Init() API. + + (#) For the UART RS485 Driver Enabled mode, initialize the UART registers + by calling the HAL_RS485Ex_Init() API. + + [..] + (@) These API's (HAL_UART_Init(), HAL_HalfDuplex_Init(), HAL_LIN_Init(), HAL_MultiProcessor_Init(), + also configure the low level Hardware GPIO, CLOCK, CORTEX...etc) by + calling the customized HAL_UART_MspInit() API. + + ##### Callback registration ##### + ================================== + + [..] + The compilation define USE_HAL_UART_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + [..] + Use Function HAL_UART_RegisterCallback() to register a user callback. + Function HAL_UART_RegisterCallback() allows to register following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) WakeupCallback : Wakeup Callback. + (+) RxFifoFullCallback : Rx Fifo Full Callback. + (+) TxFifoEmptyCallback : Tx Fifo Empty Callback. + (+) MspInitCallback : UART MspInit. + (+) MspDeInitCallback : UART MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function HAL_UART_UnRegisterCallback() to reset a callback to the default + weak function. + HAL_UART_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) WakeupCallback : Wakeup Callback. + (+) RxFifoFullCallback : Rx Fifo Full Callback. + (+) TxFifoEmptyCallback : Tx Fifo Empty Callback. + (+) MspInitCallback : UART MspInit. + (+) MspDeInitCallback : UART MspDeInit. + + [..] + For specific callback RxEventCallback, use dedicated registration/reset functions: + respectively HAL_UART_RegisterRxEventCallback() , HAL_UART_UnRegisterRxEventCallback(). + + [..] + By default, after the HAL_UART_Init() and when the state is HAL_UART_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_UART_TxCpltCallback(), HAL_UART_RxHalfCpltCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak functions in the HAL_UART_Init() + and HAL_UART_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the HAL_UART_Init() and HAL_UART_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_UART_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_UART_STATE_READY or HAL_UART_STATE_RESET state, thus registered (user) + MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using HAL_UART_RegisterCallback() before calling HAL_UART_DeInit() + or HAL_UART_Init() function. + + [..] + When The compilation define USE_HAL_UART_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available + and weak callbacks are used. + + + @endverbatim +
