mbed_official 87:085cde657901 17 ==============================================================================
mbed_official 87:085cde657901 18 [..]
mbed_official 87:085cde657901 19 The IRDA HAL driver can be used as follow:
mbed_official 87:085cde657901 20
mbed_official 87:085cde657901 21 (#) Declare a IRDA_HandleTypeDef handle structure.
mbed_official 87:085cde657901 22 (#) Initialize the IRDA low level resources by implement the HAL_IRDA_MspInit() API:
mbed_official 87:085cde657901 23 (##) Enable the USARTx interface clock.
mbed_official 87:085cde657901 24 (##) IRDA pins configuration:
mbed_official 87:085cde657901 25 (+++) Enable the clock for the IRDA GPIOs.
mbed_official 87:085cde657901 26 (+++) Configure these IRDA pins as alternate function pull-up.
mbed_official 87:085cde657901 27 (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
mbed_official 87:085cde657901 28 and HAL_IRDA_Receive_IT() APIs):
mbed_official 87:085cde657901 29 (+++) Configure the USARTx interrupt priority.
mbed_official 87:085cde657901 30 (+++) Enable the NVIC USART IRQ handle.
mbed_official 87:085cde657901 31 (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
mbed_official 87:085cde657901 32 and HAL_IRDA_Receive_DMA() APIs):
mbed_official 87:085cde657901 33 (+++) Declare a DMA handle structure for the Tx/Rx stream.
mbed_official 87:085cde657901 34 (+++) Enable the DMAx interface clock.
mbed_official 87:085cde657901 35 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
mbed_official 87:085cde657901 36 (+++) Configure the DMA Tx/Rx Stream.
mbed_official 87:085cde657901 37 (+++) Associate the initilalized DMA handle to the IRDA DMA Tx/Rx handle.
mbed_official 87:085cde657901 38 (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
mbed_official 87:085cde657901 39
mbed_official 87:085cde657901 40 (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
mbed_official 87:085cde657901 41 and Mode(Receiver/Transmitter) in the hirda Init structure.
mbed_official 87:085cde657901 42
mbed_official 87:085cde657901 43 (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:

mbed_official 87:085cde657901 45 by calling the customed HAL_IRDA_MspInit() API.
mbed_official 87:085cde657901 46 -@@- The specific IRDA interrupts (Transmission complete interrupt,
mbed_official 87:085cde657901 47 RXNE interrupt and Error Interrupts) will be managed using the macros
mbed_official 87:085cde657901 48 __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
mbed_official 87:085cde657901 49

mbed_official 87:085cde657901 170 This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
mbed_official 87:085cde657901 171 in IrDA mode.
mbed_official 87:085cde657901 172 (+) For the asynchronous mode only these parameters can be configured:
mbed_official 87:085cde657901 173 (++) BaudRate
mbed_official 87:085cde657901 174 (++) WordLength
mbed_official 87:085cde657901 175 (++) Parity: If the parity is enabled, then the MSB bit of the data written
mbed_official 87:085cde657901 176 in the data register is transmitted but is changed by the parity bit.
mbed_official 87:085cde657901 177 Depending on the frame length defined by the M bit (8-bits or 9-bits),
mbed_official 87:085cde657901 178 the possible IRDA frame formats are as listed in the following table:
mbed_official 87:085cde657901 179 +-------------------------------------------------------------+
mbed_official 87:085cde657901 180 | M bit | PCE bit | IRDA frame |

mbed_official 87:085cde657901 189 +-------------------------------------------------------------+
mbed_official 87:085cde657901 190 (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may
mbed_official 87:085cde657901 191 not be rejected. The receiver set up time should be managed by software. The IrDA physical layer
mbed_official 87:085cde657901 192 specification specifies a minimum of 10 ms delay between transmission and
mbed_official 87:085cde657901 193 reception (IrDA is a half duplex protocol).
mbed_official 87:085cde657901 194 (++) Mode: Receiver/transmitter modes
mbed_official 87:085cde657901 195 (++) IrDAMode: the IrDA can operate in the Normal mode or in the Low power mode.
mbed_official 87:085cde657901 196 [..]
mbed_official 87:085cde657901 197 The HAL_IRDA_Init() API follows IRDA configuration procedures (details for the procedures

mbed_official 87:085cde657901 328 This subsection provides a set of functions allowing to manage the IRDA data transfers.
mbed_official 87:085cde657901 329 [..]
mbed_official 87:085cde657901 330 IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
mbed_official 87:085cde657901 331 on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
mbed_official 87:085cde657901 332 is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
mbed_official 87:085cde657901 333 While receiving data, transmission should be avoided as the data to be transmitted
mbed_official 87:085cde657901 334 could be corrupted.
mbed_official 87:085cde657901 335
mbed_official 87:085cde657901 336 (#) There are two mode of transfer:
mbed_official 87:085cde657901 337 (++) Blocking mode: The communication is performed in polling mode.
mbed_official 87:085cde657901 338 The HAL status of all data processing is returned by the same function
mbed_official 87:085cde657901 339 after finishing transfer.
mbed_official 87:085cde657901 340 (++) No-Blocking mode: The communication is performed using Interrupts
mbed_official 87:085cde657901 341 or DMA, These API's return the HAL status.
mbed_official 87:085cde657901 342 The end of the data processing will be indicated through the
mbed_official 87:085cde657901 343 dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
mbed_official 87:085cde657901 344 using DMA mode.
mbed_official 87:085cde657901 345 The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
mbed_official 87:085cde657901 346 will be executed respectivelly at the end of the transmit or Receive process
mbed_official 87:085cde657901 347 The HAL_IRDA_ErrorCallback()user callback will be executed when a communication error is detected
mbed_official 87:085cde657901 348
mbed_official 87:085cde657901 349 (#) Blocking mode API's are :
mbed_official 87:085cde657901 350 (++) HAL_IRDA_Transmit()
mbed_official 87:085cde657901 351 (++) HAL_IRDA_Receive()
mbed_official 87:085cde657901 352
mbed_official 87:085cde657901 353 (#) Non-Blocking mode API's with Interrupt are :
mbed_official 87:085cde657901 354 (++) HAL_IRDA_Transmit_IT()
mbed_official 87:085cde657901 355 (++) HAL_IRDA_Receive_IT()
