@verbatim - =============================================================================== - ##### 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, 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. - (+) 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. - (+) 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. -

[..] - This subsection provides a set of functions allowing to initialize the USARTx or the UARTy - in asynchronous mode. - (+) For the asynchronous mode the parameters below can be configured: - (++) Baud Rate - (++) Word Length - (++) Stop Bit - (++) Parity: If the parity is enabled, then the MSB bit of the data written - in the data register is transmitted but is changed by the parity bit. - (++) Hardware flow control - (++) Receiver/transmitter modes - (++) Over Sampling Method - (++) One-Bit Sampling Method - (+) For the asynchronous mode, the following advanced features can be configured as well: - (++) TX and/or RX pin level inversion - (++) data logical level inversion - (++) RX and TX pins swap - (++) RX overrun detection disabling - (++) DMA disabling on RX error - (++) MSB first on communication line - (++) auto Baud rate detection - [..] - The HAL_UART_Init(), HAL_HalfDuplex_Init(), HAL_LIN_Init()and HAL_MultiProcessor_Init()API - follow respectively the UART asynchronous, UART Half duplex, UART LIN mode - and UART multiprocessor mode configuration procedures (details for the procedures - are available in reference manual). - -@endverbatim - - Depending on the frame length defined by the M1 and M0 bits (7-bit, - 8-bit or 9-bit), the possible UART formats are listed in the - following table. -
