16 | ##### How to use this driver #####
|
---|
17 | ==============================================================================
|
---|
18 | [..]
|
---|
19 | The IRDA HAL driver can be used as follows:
|
---|
20 |
|
---|
21 | (#) Declare a IRDA_HandleTypeDef handle structure.
|
---|
22 | (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
|
---|
23 | (##) Enable the USARTx interface clock.
|
---|
24 | (##) IRDA pins configuration:
|
---|
25 | (+++) Enable the clock for the IRDA GPIOs.
|
---|
26 | (+++) Configure these IRDA pins as alternate function pull-up.
|
---|
27 | (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
|
---|
28 | and HAL_IRDA_Receive_IT() APIs):
|
---|
29 | (+++) Configure the USARTx interrupt priority.
|
---|
30 | (+++) Enable the NVIC USART IRQ handle.
|
---|
31 | (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
|
---|
32 | and HAL_IRDA_Receive_DMA() APIs):
|
---|
33 | (+++) Declare a DMA handle structure for the Tx/Rx stream.
|
---|
34 | (+++) Enable the DMAx interface clock.
|
---|
35 | (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
|
---|
36 | (+++) Configure the DMA Tx/Rx Stream.
|
---|
37 | (+++) Associate the initialized DMA handle to the IRDA DMA Tx/Rx handle.
|
---|
38 | (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
|
---|
39 |
|
---|
40 | (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
|
---|
41 | and Mode(Receiver/Transmitter) in the hirda Init structure.
|
---|
42 |
|
---|
43 | (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
|
---|
44 | (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
|
---|
45 | by calling the customized HAL_IRDA_MspInit() API.
|
---|
46 | -@@- The specific IRDA interrupts (Transmission complete interrupt,
|
---|
47 | RXNE interrupt and Error Interrupts) will be managed using the macros
|
---|
48 | __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
|
---|
49 |
|
---|
50 | (#) Three operation modes are available within this driver :
|
---|
51 |
|
---|
52 | *** Polling mode IO operation ***
|
---|

182 | [..]
|
---|
183 | This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
|
---|
184 | in IrDA mode.
|
---|
185 | (+) For the asynchronous mode only these parameters can be configured:
|
---|
186 | (++) BaudRate
|
---|
187 | (++) WordLength
|
---|
188 | (++) Parity: If the parity is enabled, then the MSB bit of the data written
|
---|
189 | in the data register is transmitted but is changed by the parity bit.
|
---|
190 | Depending on the frame length defined by the M bit (8-bits or 9-bits),
|
---|
191 | please refer to Reference manual for possible IRDA frame formats.
|
---|
192 | (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may
|
---|
193 | not be rejected. The receiver set up time should be managed by software. The IrDA physical layer
|
---|
194 | specification specifies a minimum of 10 ms delay between transmission and
|
---|
195 | reception (IrDA is a half duplex protocol).
|
---|
196 | (++) Mode: Receiver/transmitter modes
|
---|
197 | (++) IrDAMode: the IrDA can operate in the Normal mode or in the Low power mode.
|
---|
198 | [..]
|
---|
199 | The HAL_IRDA_Init() API follows IRDA configuration procedures (details for the procedures
|
---|
200 | are available in reference manual).

339 | This subsection provides a set of functions allowing to manage the IRDA data transfers.
|
---|
340 | [..]
|
---|
341 | IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
|
---|
342 | on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
|
---|
343 | is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
|
---|
344 | While receiving data, transmission should be avoided as the data to be transmitted
|
---|
345 | could be corrupted.
|
---|
346 |
|
---|
347 | (#) There are two modes of transfer:
|
---|
348 | (++) Blocking mode: The communication is performed in polling mode.
|
---|
349 | The HAL status of all data processing is returned by the same function
|
---|
350 | after finishing transfer.
|
---|
351 | (++) No-Blocking mode: The communication is performed using Interrupts
|
---|
352 | or DMA, These APIs return the HAL status.
|
---|
353 | The end of the data processing will be indicated through the
|
---|
354 | dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
|
---|
355 | using DMA mode.
|
---|
356 | The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
