- @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 @ref HAL_UART_RegisterCallback() to register a user callback.
- Function @ref 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 @ref HAL_UART_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function.
- @ref 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.
-
- [..]
- By default, after the @ref HAL_UART_Init() and when the state is HAL_UART_STATE_RESET
- all callbacks are set to the corresponding weak (surcharged) functions:
- examples @ref HAL_UART_TxCpltCallback(), @ref HAL_UART_RxHalfCpltCallback().
- Exception done for MspInit and MspDeInit functions that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_UART_Init()
- and @ref HAL_UART_DeInit() only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_UART_Init() and @ref 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 @ref HAL_UART_RegisterCallback() before calling @ref HAL_UART_DeInit()
- or @ref 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 (surcharged) callbacks are used.

- ##### Initialization and Configuration functions #####
- ===============================================================================
- [..]
- 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).
-

-
- 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.

-@verbatim
- ===============================================================================
- ##### IO operation functions #####
- ===============================================================================
- This subsection provides a set of functions allowing to manage the UART asynchronous
- and Half duplex data transfers.
-
- (#) There are two mode of transfer:
- (+) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (+) Non-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated UART IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_UART_TxCpltCallback(), HAL_UART_RxCpltCallback() user callbacks
- will be executed respectively at the end of the transmit or Receive process
- The HAL_UART_ErrorCallback()user callback will be executed when a communication error is detected
-
- (#) Blocking mode API's are :
- (+) HAL_UART_Transmit()
- (+) HAL_UART_Receive()
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_UART_Transmit_IT()
- (+) HAL_UART_Receive_IT()
- (+) HAL_UART_IRQHandler()
-
- (#) Non-Blocking mode API's with DMA are :
- (+) HAL_UART_Transmit_DMA()
- (+) HAL_UART_Receive_DMA()
- (+) HAL_UART_DMAPause()
- (+) HAL_UART_DMAResume()
- (+) HAL_UART_DMAStop()
-
- (#) A set of Transfer Complete Callbacks are provided in Non_Blocking mode:
- (+) HAL_UART_TxHalfCpltCallback()
- (+) HAL_UART_TxCpltCallback()
- (+) HAL_UART_RxHalfCpltCallback()
- (+) HAL_UART_RxCpltCallback()
- (+) HAL_UART_ErrorCallback()
-
- (#) Non-Blocking mode transfers could be aborted using Abort API's :
- (+) HAL_UART_Abort()
- (+) HAL_UART_AbortTransmit()
- (+) HAL_UART_AbortReceive()
- (+) HAL_UART_Abort_IT()
- (+) HAL_UART_AbortTransmit_IT()
- (+) HAL_UART_AbortReceive_IT()
-
- (#) For Abort services based on interrupts (HAL_UART_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
- (+) HAL_UART_AbortCpltCallback()
- (+) HAL_UART_AbortTransmitCpltCallback()
- (+) HAL_UART_AbortReceiveCpltCallback()
-
- (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
- Errors are handled as follows :
- (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
- to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
- Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
- and HAL_UART_ErrorCallback() user callback is executed. Transfer is kept ongoing on UART side.
- If user wants to abort it, Abort services should be called by user.
- (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
- This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
- Error code is set to allow user to identify error type, and HAL_UART_ErrorCallback() user callback is executed.
-
- -@- In the Half duplex communication, it is forbidden to run the transmit
- and receive process in parallel, the UART state HAL_UART_STATE_BUSY_TX_RX can't be useful.
