bogdanm 0:9b334a45a8ff 16 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 17 ==============================================================================
bogdanm 0:9b334a45a8ff 18 [..]
bogdanm 0:9b334a45a8ff 19 The IRDA HAL driver can be used as follows:
bogdanm 0:9b334a45a8ff 20
bogdanm 0:9b334a45a8ff 21 (#) Declare a IRDA_HandleTypeDef handle structure.
bogdanm 0:9b334a45a8ff 22 (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
bogdanm 0:9b334a45a8ff 23 (##) Enable the USARTx interface clock.
bogdanm 0:9b334a45a8ff 24 (##) IRDA pins configuration:
bogdanm 0:9b334a45a8ff 25 (+++) Enable the clock for the IRDA GPIOs.
bogdanm 0:9b334a45a8ff 26 (+++) Configure these IRDA pins as alternate function pull-up.
bogdanm 0:9b334a45a8ff 27 (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
bogdanm 0:9b334a45a8ff 28 and HAL_IRDA_Receive_IT() APIs):
bogdanm 0:9b334a45a8ff 29 (+++) Configure the USARTx interrupt priority.
bogdanm 0:9b334a45a8ff 30 (+++) Enable the NVIC USART IRQ handle.
bogdanm 0:9b334a45a8ff 31 (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
bogdanm 0:9b334a45a8ff 32 and HAL_IRDA_Receive_DMA() APIs):
bogdanm 0:9b334a45a8ff 33 (+++) Declare a DMA handle structure for the Tx/Rx stream.
bogdanm 0:9b334a45a8ff 34 (+++) Enable the DMAx interface clock.
bogdanm 0:9b334a45a8ff 35 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
bogdanm 0:9b334a45a8ff 36 (+++) Configure the DMA Tx/Rx Stream.
bogdanm 0:9b334a45a8ff 37 (+++) Associate the initialized DMA handle to the IRDA DMA Tx/Rx handle.
bogdanm 0:9b334a45a8ff 38 (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
bogdanm 0:9b334a45a8ff 39
bogdanm 0:9b334a45a8ff 40 (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
bogdanm 0:9b334a45a8ff 41 and Mode(Receiver/Transmitter) in the hirda Init structure.
bogdanm 0:9b334a45a8ff 42
bogdanm 0:9b334a45a8ff 43 (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
bogdanm 0:9b334a45a8ff 44 (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
bogdanm 0:9b334a45a8ff 45 by calling the customized HAL_IRDA_MspInit() API.
bogdanm 0:9b334a45a8ff 46 -@@- The specific IRDA interrupts (Transmission complete interrupt,
bogdanm 0:9b334a45a8ff 47 RXNE interrupt and Error Interrupts) will be managed using the macros
bogdanm 0:9b334a45a8ff 48 __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
bogdanm 0:9b334a45a8ff 49

bogdanm 0:9b334a45a8ff 185 [..]
bogdanm 0:9b334a45a8ff 186 This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
bogdanm 0:9b334a45a8ff 187 in IrDA mode.
bogdanm 0:9b334a45a8ff 188 (+) For the asynchronous mode only these parameters can be configured:
bogdanm 0:9b334a45a8ff 189 (++) BaudRate
bogdanm 0:9b334a45a8ff 190 (++) WordLength
bogdanm 0:9b334a45a8ff 191 (++) Parity: If the parity is enabled, then the MSB bit of the data written
bogdanm 0:9b334a45a8ff 192 in the data register is transmitted but is changed by the parity bit.
bogdanm 0:9b334a45a8ff 193 Depending on the frame length defined by the M bit (8-bits or 9-bits),
bogdanm 0:9b334a45a8ff 194 please refer to Reference manual for possible IRDA frame formats.
bogdanm 0:9b334a45a8ff 195 (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may
bogdanm 0:9b334a45a8ff 196 not be rejected. The receiver set up time should be managed by software. The IrDA physical layer
bogdanm 0:9b334a45a8ff 197 specification specifies a minimum of 10 ms delay between transmission and
bogdanm 0:9b334a45a8ff 198 reception (IrDA is a half duplex protocol).
bogdanm 0:9b334a45a8ff 199 (++) Mode: Receiver/transmitter modes
bogdanm 0:9b334a45a8ff 200 (++) IrDAMode: the IrDA can operate in the Normal mode or in the Low power mode.
bogdanm 0:9b334a45a8ff 201 [..]
bogdanm 0:9b334a45a8ff 202 The HAL_IRDA_Init() API follows IRDA configuration procedures (details for the procedures

bogdanm 0:9b334a45a8ff 329 This subsection provides a set of functions allowing to manage the IRDA data transfers.
bogdanm 0:9b334a45a8ff 330 [..]
bogdanm 0:9b334a45a8ff 331 IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
bogdanm 0:9b334a45a8ff 332 on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
bogdanm 0:9b334a45a8ff 333 is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
bogdanm 0:9b334a45a8ff 334 While receiving data, transmission should be avoided as the data to be transmitted
bogdanm 0:9b334a45a8ff 335 could be corrupted.
bogdanm 0:9b334a45a8ff 336
bogdanm 0:9b334a45a8ff 337 (#) There are two modes of transfer:
bogdanm 0:9b334a45a8ff 338 (++) Blocking mode: the communication is performed in polling mode.
bogdanm 0:9b334a45a8ff 339 The HAL status of all data processing is returned by the same function
bogdanm 0:9b334a45a8ff 340 after finishing transfer.
bogdanm 0:9b334a45a8ff 341 (++) No-Blocking mode: the communication is performed using Interrupts
bogdanm 0:9b334a45a8ff 342 or DMA, these API's return the HAL status.
bogdanm 0:9b334a45a8ff 343 The end of the data processing will be indicated through the
bogdanm 0:9b334a45a8ff 344 dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
bogdanm 0:9b334a45a8ff 345 using DMA mode.
bogdanm 0:9b334a45a8ff 346 The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
bogdanm 0:9b334a45a8ff 347 will be executed respectively at the end of the Transmit or Receive process
bogdanm 0:9b334a45a8ff 348 The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
bogdanm 0:9b334a45a8ff 349
bogdanm 0:9b334a45a8ff 350 (#) Blocking mode API's are :
bogdanm 0:9b334a45a8ff 351 (++) HAL_IRDA_Transmit()
bogdanm 0:9b334a45a8ff 352 (++) HAL_IRDA_Receive()
bogdanm 0:9b334a45a8ff 353
bogdanm 0:9b334a45a8ff 354 (#) Non-Blocking mode API's with Interrupt are :
bogdanm 0:9b334a45a8ff 355 (++) HAL_IRDA_Transmit_IT()
bogdanm 0:9b334a45a8ff 356 (++) HAL_IRDA_Receive_IT()
bogdanm 0:9b334a45a8ff 357 (++) HAL_IRDA_IRQHandler()
bogdanm 0:9b334a45a8ff 358 (++) IRDA_Transmit_IT()
bogdanm 0:9b334a45a8ff 359 (++) IRDA_Receive_IT()
bogdanm 0:9b334a45a8ff 360
bogdanm 0:9b334a45a8ff 361 (#) Non-Blocking mode functions with DMA are :
bogdanm 0:9b334a45a8ff 362 (++) HAL_IRDA_Transmit_DMA()
bogdanm 0:9b334a45a8ff 363 (++) HAL_IRDA_Receive_DMA()
bogdanm 0:9b334a45a8ff 364
bogdanm 0:9b334a45a8ff 365 (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
