27 ##### How to use this driver #####
28 ==============================================================================
29 [..]
30 The IRDA HAL driver can be used as follows:
31
32 (#) Declare a IRDA_HandleTypeDef handle structure (eg. IRDA_HandleTypeDef hirda).
33 (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API
34 in setting the associated USART or UART in IRDA mode:
35 (++) Enable the USARTx/UARTx interface clock.
36 (++) USARTx/UARTx pins configuration:
37 (+++) Enable the clock for the USARTx/UARTx GPIOs.
38 (+++) Configure these USARTx/UARTx pins (TX as alternate function pull-up, RX as alternate function Input).
39 (++) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
40 and HAL_IRDA_Receive_IT() APIs):
41 (+++) Configure the USARTx/UARTx interrupt priority.
42 (+++) Enable the NVIC USARTx/UARTx IRQ handle.
43 (+++) The specific IRDA interrupts (Transmission complete interrupt,
44 RXNE interrupt and Error Interrupts) will be managed using the macros
45 __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
46
47 (++) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
48 and HAL_IRDA_Receive_DMA() APIs):
49 (+++) Declare a DMA handle structure for the Tx/Rx channel.
50 (+++) Enable the DMAx interface clock.
51 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
52 (+++) Configure the DMA Tx/Rx channel.
53 (+++) Associate the initialized DMA handle to the IRDA DMA Tx/Rx handle.
54 (+++) Configure the priority and enable the NVIC for the transfer
55 complete interrupt on the DMA Tx/Rx channel.
56
57 (#) Program the Baud Rate, Word Length and Parity and Mode(Receiver/Transmitter),
58 the normal or low power mode and the clock prescaler in the hirda handle Init structure.
59
60 (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
61 (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
62 by calling the customized HAL_IRDA_MspInit() API.
63
64 -@@- The specific IRDA interrupts (Transmission complete interrupt,
65 RXNE interrupt and Error Interrupts) will be managed using the macros
66 __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
67
68 (#) Three operation modes are available within this driver :

104 *** IRDA HAL driver macros list ***
105 ====================================
106 [..]

108
109 (+) __HAL_IRDA_ENABLE: Enable the IRDA peripheral

116
117 [..]
118 (@) You can refer to the IRDA HAL driver header file for more useful macros
119
120 ##### Callback registration #####
121 ==================================
122
123 [..]
124 The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS when set to 1
125 allows the user to configure dynamically the driver callbacks.
126
127 [..]
128 Use Function HAL_IRDA_RegisterCallback() to register a user callback.
129 Function HAL_IRDA_RegisterCallback() allows to register following callbacks:
130 (+) TxHalfCpltCallback : Tx Half Complete Callback.
131 (+) TxCpltCallback : Tx Complete Callback.
132 (+) RxHalfCpltCallback : Rx Half Complete Callback.
133 (+) RxCpltCallback : Rx Complete Callback.
134 (+) ErrorCallback : Error Callback.
135 (+) AbortCpltCallback : Abort Complete Callback.
136 (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
137 (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
138 (+) MspInitCallback : IRDA MspInit.
139 (+) MspDeInitCallback : IRDA MspDeInit.
140 This function takes as parameters the HAL peripheral handle, the Callback ID
141 and a pointer to the user callback function.
142
143 [..]
144 Use function HAL_IRDA_UnRegisterCallback() to reset a callback to the default
145 weak (surcharged) function.
146 HAL_IRDA_UnRegisterCallback() takes as parameters the HAL peripheral handle,
147 and the Callback ID.
148 This function allows to reset following callbacks:
149 (+) TxHalfCpltCallback : Tx Half Complete Callback.
150 (+) TxCpltCallback : Tx Complete Callback.
151 (+) RxHalfCpltCallback : Rx Half Complete Callback.
152 (+) RxCpltCallback : Rx Complete Callback.
153 (+) ErrorCallback : Error Callback.
154 (+) AbortCpltCallback : Abort Complete Callback.
155 (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
156 (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
157 (+) MspInitCallback : IRDA MspInit.
158 (+) MspDeInitCallback : IRDA MspDeInit.
159
160 [..]
161 By default, after the HAL_IRDA_Init() and when the state is HAL_IRDA_STATE_RESET
162 all callbacks are set to the corresponding weak (surcharged) functions:
163 examples HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxHalfCpltCallback().
164 Exception done for MspInit and MspDeInit functions that are respectively
165 reset to the legacy weak (surcharged) functions in the HAL_IRDA_Init()
166 and HAL_IRDA_DeInit() only when these callbacks are null (not registered beforehand).
167 If not, MspInit or MspDeInit are not null, the HAL_IRDA_Init() and HAL_IRDA_DeInit()
168 keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
169
170 [..]
171 Callbacks can be registered/unregistered in HAL_IRDA_STATE_READY state only.
172 Exception done MspInit/MspDeInit that can be registered/unregistered
173 in HAL_IRDA_STATE_READY or HAL_IRDA_STATE_RESET state, thus registered (user)
174 MspInit/DeInit callbacks can be used during the Init/DeInit.
175 In that case first register the MspInit/MspDeInit user callbacks
176 using HAL_IRDA_RegisterCallback() before calling HAL_IRDA_DeInit()
177 or HAL_IRDA_Init() function.
178
179 [..]
180 When The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS is set to 0 or
181 not defined, the callback registration feature is not available
182 and weak (surcharged) callbacks are used.

280 This subsection provides a set of functions allowing to initialize the USARTx
281 in asynchronous IRDA mode.
282 (+) For the asynchronous mode only these parameters can be configured:
283 (++) Baud Rate
284 (++) Word Length
285 (++) Parity: If the parity is enabled, then the MSB bit of the data written
286 in the data register is transmitted but is changed by the parity bit.
287 (++) Power mode
288 (++) Prescaler setting
289 (++) Receiver/transmitter modes
290
291 [..]
292 The HAL_IRDA_Init() API follows the USART asynchronous configuration procedures
293 (details for the procedures are available in reference manual).

704 ===============================================================================
705 ##### IO operation functions #####
706 ===============================================================================
707 [..]
708 This subsection provides a set of functions allowing to manage the IRDA data transfers.
709
710 [..]
711 IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
712 on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
713 is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
714 While receiving data, transmission should be avoided as the data to be transmitted
715 could be corrupted.
716
717 [..]
718 (#) There are two modes of transfer:
719 (++) Blocking mode: the communication is performed in polling mode.
720 The HAL status of all data processing is returned by the same function
721 after finishing transfer.
722 (++) Non-Blocking mode: the communication is performed using Interrupts
723 or DMA, these API's return the HAL status.
724 The end of the data processing will be indicated through the
725 dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
726 using DMA mode.
727 The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
728 will be executed respectively at the end of the Transmit or Receive process
729 The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
730
731 (#) Blocking mode APIs are :
732 (++) HAL_IRDA_Transmit()
733 (++) HAL_IRDA_Receive()
734
735 (#) Non Blocking mode APIs with Interrupt are :
736 (++) HAL_IRDA_Transmit_IT()
737 (++) HAL_IRDA_Receive_IT()
738 (++) HAL_IRDA_IRQHandler()
739
740 (#) Non Blocking mode functions with DMA are :
741 (++) HAL_IRDA_Transmit_DMA()
742 (++) HAL_IRDA_Receive_DMA()
743 (++) HAL_IRDA_DMAPause()
744 (++) HAL_IRDA_DMAResume()
745 (++) HAL_IRDA_DMAStop()
746
747 (#) A set of Transfer Complete Callbacks are provided in Non Blocking mode:
748 (++) HAL_IRDA_TxHalfCpltCallback()
749 (++) HAL_IRDA_TxCpltCallback()
750 (++) HAL_IRDA_RxHalfCpltCallback()
751 (++) HAL_IRDA_RxCpltCallback()
752 (++) HAL_IRDA_ErrorCallback()
753
754 (#) Non-Blocking mode transfers could be aborted using Abort API's :
755 (++) HAL_IRDA_Abort()
756 (++) HAL_IRDA_AbortTransmit()
757 (++) HAL_IRDA_AbortReceive()
758 (++) HAL_IRDA_Abort_IT()
759 (++) HAL_IRDA_AbortTransmit_IT()
760 (++) HAL_IRDA_AbortReceive_IT()
761
762 (#) For Abort services based on interrupts (HAL_IRDA_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
763 (++) HAL_IRDA_AbortCpltCallback()
764 (++) HAL_IRDA_AbortTransmitCpltCallback()
765 (++) HAL_IRDA_AbortReceiveCpltCallback()
766
767 (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
768 Errors are handled as follows :
769 (++) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
770 to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error
771 in Interrupt mode reception .
772 Received character is then retrieved and stored in Rx buffer, Error code is set to allow user
773 to identify error type, and HAL_IRDA_ErrorCallback() user callback is executed.
774 Transfer is kept ongoing on IRDA side.
775 If user wants to abort it, Abort services should be called by user.
776 (++) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
777 This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
778 Error code is set to allow user to identify error type, and
779 HAL_IRDA_ErrorCallback() user callback is executed.
