phungductung 0:e87aa4c49e95 16 ##### How to use this driver #####
phungductung 0:e87aa4c49e95 17 ==============================================================================
phungductung 0:e87aa4c49e95 18 [..]
phungductung 0:e87aa4c49e95 19 The IRDA HAL driver can be used as follows:
phungductung 0:e87aa4c49e95 20
phungductung 0:e87aa4c49e95 21 (#) Declare a IRDA_HandleTypeDef handle structure.
phungductung 0:e87aa4c49e95 22 (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
phungductung 0:e87aa4c49e95 23 (##) Enable the USARTx interface clock.
phungductung 0:e87aa4c49e95 24 (##) IRDA pins configuration:
phungductung 0:e87aa4c49e95 25 (+++) Enable the clock for the IRDA GPIOs.
phungductung 0:e87aa4c49e95 26 (+++) Configure these IRDA pins as alternate function pull-up.
phungductung 0:e87aa4c49e95 27 (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
phungductung 0:e87aa4c49e95 28 and HAL_IRDA_Receive_IT() APIs):
phungductung 0:e87aa4c49e95 29 (+++) Configure the USARTx interrupt priority.
phungductung 0:e87aa4c49e95 30 (+++) Enable the NVIC USART IRQ handle.
phungductung 0:e87aa4c49e95 31 (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
phungductung 0:e87aa4c49e95 32 and HAL_IRDA_Receive_DMA() APIs):
phungductung 0:e87aa4c49e95 33 (+++) Declare a DMA handle structure for the Tx/Rx stream.
phungductung 0:e87aa4c49e95 34 (+++) Enable the DMAx interface clock.
phungductung 0:e87aa4c49e95 35 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
phungductung 0:e87aa4c49e95 36 (+++) Configure the DMA Tx/Rx Stream.
phungductung 0:e87aa4c49e95 37 (+++) Associate the initialized DMA handle to the IRDA DMA Tx/Rx handle.
phungductung 0:e87aa4c49e95 38 (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
phungductung 0:e87aa4c49e95 39
phungductung 0:e87aa4c49e95 40 (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
phungductung 0:e87aa4c49e95 41 and Mode(Receiver/Transmitter) in the hirda Init structure.
phungductung 0:e87aa4c49e95 42
phungductung 0:e87aa4c49e95 43 (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
phungductung 0:e87aa4c49e95 44 (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
phungductung 0:e87aa4c49e95 45 by calling the customized HAL_IRDA_MspInit() API.
phungductung 0:e87aa4c49e95 46 -@@- The specific IRDA interrupts (Transmission complete interrupt,
phungductung 0:e87aa4c49e95 47 RXNE interrupt and Error Interrupts) will be managed using the macros
phungductung 0:e87aa4c49e95 48 __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
phungductung 0:e87aa4c49e95 49
phungductung 0:e87aa4c49e95 50 (#) Three operation modes are available within this driver :

phungductung 0:e87aa4c49e95 186 This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
phungductung 0:e87aa4c49e95 187 in IrDA mode.
phungductung 0:e87aa4c49e95 188 (+) For the asynchronous mode only these parameters can be configured:
phungductung 0:e87aa4c49e95 189 (++) BaudRate
phungductung 0:e87aa4c49e95 190 (++) WordLength
phungductung 0:e87aa4c49e95 191 (++) Parity: If the parity is enabled, then the MSB bit of the data written
phungductung 0:e87aa4c49e95 192 in the data register is transmitted but is changed by the parity bit.
phungductung 0:e87aa4c49e95 193 Depending on the frame length defined by the M bit (8-bits or 9-bits),
phungductung 0:e87aa4c49e95 194 please refer to Reference manual for possible IRDA frame formats.
phungductung 0:e87aa4c49e95 195 (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may
phungductung 0:e87aa4c49e95 196 not be rejected. The receiver set up time should be managed by software. The IrDA physical layer
phungductung 0:e87aa4c49e95 197 specification specifies a minimum of 10 ms delay between transmission and
phungductung 0:e87aa4c49e95 198 reception (IrDA is a half duplex protocol).
phungductung 0:e87aa4c49e95 199 (++) Mode: Receiver/transmitter modes
phungductung 0:e87aa4c49e95 200 (++) IrDAMode: the IrDA can operate in the Normal mode or in the Low power mode.
phungductung 0:e87aa4c49e95 201 [..]

phungductung 0:e87aa4c49e95 334 ===============================================================================
phungductung 0:e87aa4c49e95 335 This subsection provides a set of functions allowing to manage the IRDA data transfers.
phungductung 0:e87aa4c49e95 336 [..]
phungductung 0:e87aa4c49e95 337 IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
phungductung 0:e87aa4c49e95 338 on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
phungductung 0:e87aa4c49e95 339 is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
phungductung 0:e87aa4c49e95 340 While receiving data, transmission should be avoided as the data to be transmitted
phungductung 0:e87aa4c49e95 341 could be corrupted.
phungductung 0:e87aa4c49e95 342
phungductung 0:e87aa4c49e95 343 (#) There are two modes of transfer:
phungductung 0:e87aa4c49e95 344 (++) Blocking mode: the communication is performed in polling mode.
phungductung 0:e87aa4c49e95 345 The HAL status of all data processing is returned by the same function
phungductung 0:e87aa4c49e95 346 after finishing transfer.
phungductung 0:e87aa4c49e95 347 (++) No-Blocking mode: the communication is performed using Interrupts
phungductung 0:e87aa4c49e95 348 or DMA, these API's return the HAL status.
phungductung 0:e87aa4c49e95 349 The end of the data processing will be indicated through the
phungductung 0:e87aa4c49e95 350 dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
phungductung 0:e87aa4c49e95 351 using DMA mode.
phungductung 0:e87aa4c49e95 352 The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
phungductung 0:e87aa4c49e95 353 will be executed respectively at the end of the Transmit or Receive process
phungductung 0:e87aa4c49e95 354 The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
phungductung 0:e87aa4c49e95 355
phungductung 0:e87aa4c49e95 356 (#) Blocking mode API's are :
phungductung 0:e87aa4c49e95 357 (++) HAL_IRDA_Transmit()
phungductung 0:e87aa4c49e95 358 (++) HAL_IRDA_Receive()
phungductung 0:e87aa4c49e95 359
phungductung 0:e87aa4c49e95 360 (#) Non-Blocking mode API's with Interrupt are :
phungductung 0:e87aa4c49e95 361 (++) HAL_IRDA_Transmit_IT()
phungductung 0:e87aa4c49e95 362 (++) HAL_IRDA_Receive_IT()
phungductung 0:e87aa4c49e95 363 (++) HAL_IRDA_IRQHandler()
phungductung 0:e87aa4c49e95 364 (++) IRDA_Transmit_IT()
phungductung 0:e87aa4c49e95 365 (++) IRDA_Receive_IT()
phungductung 0:e87aa4c49e95 366
phungductung 0:e87aa4c49e95 367 (#) Non-Blocking mode functions with DMA are :
phungductung 0:e87aa4c49e95 368 (++) HAL_IRDA_Transmit_DMA()
phungductung 0:e87aa4c49e95 369 (++) HAL_IRDA_Receive_DMA()
phungductung 0:e87aa4c49e95 370
