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 :

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 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 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 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 callbacks are used.

284 This subsection provides a set of functions allowing to initialize the USARTx
285 in asynchronous IRDA mode.
286 (+) For the asynchronous mode only these parameters can be configured:
287 (++) Baud Rate
288 (++) Word Length
289 (++) Parity: If the parity is enabled, then the MSB bit of the data written
290 in the data register is transmitted but is changed by the parity bit.
291 (++) Power mode
292 (++) Prescaler setting
293 (++) Receiver/transmitter modes
294
295 [..]
296 The HAL_IRDA_Init() API follows the USART asynchronous configuration procedures
297 (details for the procedures are available in reference manual).

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