- ##### How to use this driver #####
- ==============================================================================
- [..]
- The IRDA HAL driver can be used as follows:
-
- (#) Declare a IRDA_HandleTypeDef handle structure (eg. IRDA_HandleTypeDef hirda).
- (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API
- in setting the associated USART or UART in IRDA mode:
- (++) Enable the USARTx/UARTx interface clock.
- (++) USARTx/UARTx pins configuration:
- (+++) Enable the clock for the USARTx/UARTx GPIOs.
- (+++) Configure these USARTx/UARTx pins (TX as alternate function pull-up, RX as alternate function Input).
- (++) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
- and HAL_IRDA_Receive_IT() APIs):
- (+++) Configure the USARTx/UARTx interrupt priority.
- (+++) Enable the NVIC USARTx/UARTx IRQ handle.
- (+++) The specific IRDA interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
-
- (++) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
- and HAL_IRDA_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 IRDA 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 and Parity and Mode(Receiver/Transmitter),
- the normal or low power mode and the clock prescaler in the hirda handle Init structure.
-
- (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
- (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customized HAL_IRDA_MspInit() API.
-
- -@@- The specific IRDA interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
-
- (#) Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_IRDA_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_IRDA_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non-blocking mode using HAL_IRDA_Transmit_IT()
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback() is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback()
- (+) Receive an amount of data in non-blocking mode using HAL_IRDA_Receive_IT()
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback() is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback()
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback()
-
- *** DMA mode IO operation ***
- ==============================
- [..]
- (+) Send an amount of data in non-blocking mode (DMA) using HAL_IRDA_Transmit_DMA()
- (+) At transmission half of transfer HAL_IRDA_TxHalfCpltCallback() is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxHalfCpltCallback()
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback() is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback()
- (+) Receive an amount of data in non-blocking mode (DMA) using HAL_IRDA_Receive_DMA()
- (+) At reception half of transfer HAL_IRDA_RxHalfCpltCallback() is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxHalfCpltCallback()
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback() is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback()
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback()
-
- *** IRDA HAL driver macros list ***
- ====================================
- [..]
- Below the list of most used macros in IRDA HAL driver.
-
- (+) __HAL_IRDA_ENABLE: Enable the IRDA peripheral
- (+) __HAL_IRDA_DISABLE: Disable the IRDA peripheral
- (+) __HAL_IRDA_GET_FLAG : Check whether the specified IRDA flag is set or not
- (+) __HAL_IRDA_CLEAR_FLAG : Clear the specified IRDA pending flag
- (+) __HAL_IRDA_ENABLE_IT: Enable the specified IRDA interrupt
- (+) __HAL_IRDA_DISABLE_IT: Disable the specified IRDA interrupt
- (+) __HAL_IRDA_GET_IT_SOURCE: Check whether or not the specified IRDA interrupt is enabled
-
- [..]
- (@) You can refer to the IRDA HAL driver header file for more useful macros
-
- ##### Callback registration #####
- ==================================
-
- [..]
- The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- [..]
- Use Function @ref HAL_IRDA_RegisterCallback() to register a user callback.
- Function @ref HAL_IRDA_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 : IRDA MspInit.
- (+) MspDeInitCallback : IRDA 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_IRDA_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function.
- @ref HAL_IRDA_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 : IRDA MspInit.
- (+) MspDeInitCallback : IRDA MspDeInit.
-
- [..]
- By default, after the @ref HAL_IRDA_Init() and when the state is HAL_IRDA_STATE_RESET
- all callbacks are set to the corresponding weak (surcharged) functions:
- examples @ref HAL_IRDA_TxCpltCallback(), @ref HAL_IRDA_RxHalfCpltCallback().
- Exception done for MspInit and MspDeInit functions that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_IRDA_Init()
- and @ref HAL_IRDA_DeInit() only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_IRDA_Init() and @ref HAL_IRDA_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
-
- [..]
- Callbacks can be registered/unregistered in HAL_IRDA_STATE_READY state only.
- Exception done MspInit/MspDeInit that can be registered/unregistered
- in HAL_IRDA_STATE_READY or HAL_IRDA_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_IRDA_RegisterCallback() before calling @ref HAL_IRDA_DeInit()
- or @ref HAL_IRDA_Init() function.
-
- [..]
- When The compilation define USE_HAL_IRDA_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
- in asynchronous IRDA mode.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) 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.
- (++) Power mode
- (++) Prescaler setting
- (++) Receiver/transmitter modes
-
- [..]
- The HAL_IRDA_Init() API follows the USART asynchronous 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 IRDA frame formats are listed in the
- following table.
-

- ===============================================================================
- ##### IO operation functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to manage the IRDA data transfers.
-
- [..]
- IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
- on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
- is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
- While receiving data, transmission should be avoided as the data to be transmitted
- could be corrupted.
-
- [..]
- (#) 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 IRDA IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
- will be executed respectively at the end of the Transmit or Receive process
- The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
-
- (#) Blocking mode APIs are :
- (++) HAL_IRDA_Transmit()
- (++) HAL_IRDA_Receive()
-
- (#) Non Blocking mode APIs with Interrupt are :
- (++) HAL_IRDA_Transmit_IT()
- (++) HAL_IRDA_Receive_IT()
- (++) HAL_IRDA_IRQHandler()
-
- (#) Non Blocking mode functions with DMA are :
- (++) HAL_IRDA_Transmit_DMA()
- (++) HAL_IRDA_Receive_DMA()
- (++) HAL_IRDA_DMAPause()
- (++) HAL_IRDA_DMAResume()
- (++) HAL_IRDA_DMAStop()
-
- (#) A set of Transfer Complete Callbacks are provided in Non Blocking mode:
- (++) HAL_IRDA_TxHalfCpltCallback()
- (++) HAL_IRDA_TxCpltCallback()
- (++) HAL_IRDA_RxHalfCpltCallback()
- (++) HAL_IRDA_RxCpltCallback()
- (++) HAL_IRDA_ErrorCallback()
-
- (#) Non-Blocking mode transfers could be aborted using Abort API's :
- (++) HAL_IRDA_Abort()
- (++) HAL_IRDA_AbortTransmit()
- (++) HAL_IRDA_AbortReceive()
- (++) HAL_IRDA_Abort_IT()
- (++) HAL_IRDA_AbortTransmit_IT()
- (++) HAL_IRDA_AbortReceive_IT()
-
- (#) For Abort services based on interrupts (HAL_IRDA_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
- (++) HAL_IRDA_AbortCpltCallback()
- (++) HAL_IRDA_AbortTransmitCpltCallback()
- (++) HAL_IRDA_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_IRDA_ErrorCallback() user callback is executed. Transfer is kept ongoing on IRDA 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_IRDA_ErrorCallback() user callback is executed.
