+ ==============================================================================
+ ##### 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 HAL_IRDA_RegisterCallback() to register a user callback.
+ Function 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 HAL_IRDA_UnRegisterCallback() to reset a callback to the default
+ weak (surcharged) function.
+ 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 HAL_IRDA_Init() and when the state is HAL_IRDA_STATE_RESET
+ all callbacks are set to the corresponding weak (surcharged) functions:
+ examples HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxHalfCpltCallback().
+ Exception done for MspInit and MspDeInit functions that are respectively
+ reset to the legacy weak (surcharged) functions in the HAL_IRDA_Init()
+ and HAL_IRDA_DeInit() only when these callbacks are null (not registered beforehand).
+ If not, MspInit or MspDeInit are not null, the HAL_IRDA_Init() and 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 HAL_IRDA_RegisterCallback() before calling HAL_IRDA_DeInit()
+ or 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.
+
+ Table 1. IRDA frame format.

+ *
+@verbatim
+ ===============================================================================
+ ##### 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.
