|
|
- ##### 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 the UART TX/RX 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.
|
|
|
- (##) 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 stream.
|
|
|
- (+++) Enable the DMAx interface clock.
|
|
|
- (+++) Configure the declared DMA handle structure with the required
|
|
|
- Tx/Rx parameters.
|
|
|
- (+++) Configure the DMA Tx/Rx stream.
|
|
|
- (+++) 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 stream.
|
|
|
- (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
|
|
|
- (used for last byte sending completion detection in DMA non circular mode)
|
|
|
-
|
|
|
- (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
|
|
|
- flow control and Mode(Receiver/Transmitter) in the huart Init 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 LIN mode, initialize the UART registers by calling the HAL_LIN_Init() API.
|
|
|
-
|
|
|
- (#) For the Multi-Processor mode, initialize the UART registers by calling
|
|
|
- the HAL_MultiProcessor_Init() API.
|
|
|
-
|
|
|
- [..]
|
|
|
- (@) The specific UART interrupts (Transmission complete interrupt,
|
|
|
- RXNE interrupt and Error Interrupts) will be managed using the macros
|
|
|
- __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit
|
|
|
- and receive process.
|
|
|
-
|
|
|
- [..]
|
|
|
- (@) These APIs (HAL_UART_Init() and HAL_HalfDuplex_Init()) configure also 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.
|
|
|
- (+) 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 (surcharged) 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.
|
|
|
- (+) 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 (surcharged) functions:
|
|
|
- examples HAL_UART_TxCpltCallback(), HAL_UART_RxHalfCpltCallback().
|
|
|
- Exception done for MspInit and MspDeInit functions that are respectively
|
|
|
- reset to the legacy weak (surcharged) 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 (surcharged) callbacks are used.
|
|
|
-
|
|
|
- [..]
|
|
|
- Three operation modes are available within this driver :
|
|
|
-
|
|
|
- *** Polling mode IO operation ***
|
|
|
- =================================
|
|
|
- [..]
|
|
|
- (+) Send an amount of data in blocking mode using HAL_UART_Transmit()
|
|
|
- (+) Receive an amount of data in blocking mode using HAL_UART_Receive()
|
|
|
-
|
|
|
- *** Interrupt mode IO operation ***
|
|
|
- ===================================
|
|
|
- [..]
|
|
|
- (+) Send an amount of data in non blocking mode using HAL_UART_Transmit_IT()
|
|
|
- (+) At transmission end of transfer HAL_UART_TxCpltCallback is executed and user can
|
|
|
- add his own code by customization of function pointer HAL_UART_TxCpltCallback
|
|
|
- (+) Receive an amount of data in non blocking mode using HAL_UART_Receive_IT()
|
|
|
- (+) At reception end of transfer HAL_UART_RxCpltCallback is executed and user can
|
|
|
- add his own code by customization of function pointer HAL_UART_RxCpltCallback
|
|
|
- (+) In case of transfer Error, HAL_UART_ErrorCallback() function is executed and user can
|
|
|
- add his own code by customization of function pointer HAL_UART_ErrorCallback
|
|
|
-
|
|
|
- *** DMA mode IO operation ***
|
|
|
- ==============================
|
|
|
- [..]
|
|
|
- (+) Send an amount of data in non blocking mode (DMA) using HAL_UART_Transmit_DMA()
|
|
|
- (+) At transmission end of half transfer HAL_UART_TxHalfCpltCallback is executed and user can
|
|
|
- add his own code by customization of function pointer HAL_UART_TxHalfCpltCallback
|
|
|
- (+) At transmission end of transfer HAL_UART_TxCpltCallback is executed and user can
|
|
|
- add his own code by customization of function pointer HAL_UART_TxCpltCallback
|
|
|
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_UART_Receive_DMA()
|
|
|
- (+) At reception end of half transfer HAL_UART_RxHalfCpltCallback is executed and user can
|
|
|
- add his own code by customization of function pointer HAL_UART_RxHalfCpltCallback
|
|
|
- (+) At reception end of transfer HAL_UART_RxCpltCallback is executed and user can
|
|
|
- add his own code by customization of function pointer HAL_UART_RxCpltCallback
|
|
|
- (+) In case of transfer Error, HAL_UART_ErrorCallback() function is executed and user can
|
|
|
- add his own code by customization of function pointer HAL_UART_ErrorCallback
|
|
|
- (+) Pause the DMA Transfer using HAL_UART_DMAPause()
|
|
|
- (+) Resume the DMA Transfer using HAL_UART_DMAResume()
|
|
|
- (+) Stop the DMA Transfer using HAL_UART_DMAStop()
|
|
|
-
|
|
|
-
|
|
|
- [..] This subsection also provides a set of additional functions providing enhanced reception
|
|
|
- services to user. (For example, these functions allow application to handle use cases
|
|
|
- where number of data to be received is unknown).
|
|
|
-
|
|
|
- (#) Compared to standard reception services which only consider number of received
|
|
|
- data elements as reception completion criteria, these functions also consider additional events
|
|
|
- as triggers for updating reception status to caller :
|
|
|
- (+) Detection of inactivity period (RX line has not been active for a given period).
|
|
|
- (++) RX inactivity detected by IDLE event, i.e. RX line has been in idle state (normally high state)
|
|
|
- for 1 frame time, after last received byte.
|
|
|
-
|
|
|
- (#) There are two mode of transfer:
|
|
|
- (+) Blocking mode: The reception is performed in polling mode, until either expected number of data is received,
|
|
|
- or till IDLE event occurs. Reception is handled only during function execution.
|
|
|
- When function exits, no data reception could occur. HAL status and number of actually received data elements,
|
|
|
- are returned by function after finishing transfer.
|
|
|
- (+) Non-Blocking mode: The reception 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_UARTEx_RxEventCallback() user callback will be executed during Receive process
|
|
|
- The HAL_UART_ErrorCallback()user callback will be executed when a reception error is detected.
|
|
|
-
|
|
|
- (#) Blocking mode API:
|
|
|
- (+) HAL_UARTEx_ReceiveToIdle()
|
|
|
-
|
|
|
- (#) Non-Blocking mode API with Interrupt:
|
|
|
- (+) HAL_UARTEx_ReceiveToIdle_IT()
|
|
|
-
|
|
|
- (#) Non-Blocking mode API with DMA:
|
|
|
- (+) HAL_UARTEx_ReceiveToIdle_DMA()

- ===============================================================================
|
|
|
- This subsection provides a set of functions allowing to manage the UART asynchronous
|
|
|
- and Half duplex data transfers.
|
|
|
-
|
|
|
- (#) There are two modes 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()
|
|
|
-
|
|
|
- (#) A Rx Event Reception Callback (Rx event notification) is available for Non_Blocking modes of enhanced reception services:
|
|
|
- (+) HAL_UARTEx_RxEventCallback()
|
|
|
-
|
|
|
- (#) 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.
