bogdanm 0:9b334a45a8ff 19 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 20 ===============================================================================
bogdanm 0:9b334a45a8ff 21 [..]
bogdanm 0:9b334a45a8ff 22 The IRDA HAL driver can be used as follows:
bogdanm 0:9b334a45a8ff 23
bogdanm 0:9b334a45a8ff 24
bogdanm 0:9b334a45a8ff 25 (#) Declare a IRDA_HandleTypeDef handle structure.
bogdanm 0:9b334a45a8ff 26 (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
bogdanm 0:9b334a45a8ff 27 (##) Enable the USARTx interface clock.
bogdanm 0:9b334a45a8ff 28 (##) IRDA pins configuration:
bogdanm 0:9b334a45a8ff 29 (+) Enable the clock for the IRDA GPIOs.
bogdanm 0:9b334a45a8ff 30 (+) Configure these IRDA pins as alternate function pull-up.
bogdanm 0:9b334a45a8ff 31 (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
bogdanm 0:9b334a45a8ff 32 and HAL_IRDA_Receive_IT() APIs):
bogdanm 0:9b334a45a8ff 33 (+) Configure the USARTx interrupt priority.
bogdanm 0:9b334a45a8ff 34 (+) Enable the NVIC USART IRQ handle.
bogdanm 0:9b334a45a8ff 35 (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
bogdanm 0:9b334a45a8ff 36 and HAL_IRDA_Receive_DMA() APIs):
bogdanm 0:9b334a45a8ff 37 (+) Declare a DMA handle structure for the Tx/Rx channel.
bogdanm 0:9b334a45a8ff 38 (+) Enable the DMAx interface clock.
bogdanm 0:9b334a45a8ff 39 (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
bogdanm 0:9b334a45a8ff 40 (+) Configure the DMA Tx/Rx channel.
bogdanm 0:9b334a45a8ff 41 (+) Associate the initilalized DMA handle to the IRDA DMA Tx/Rx handle.
bogdanm 0:9b334a45a8ff 42 (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
bogdanm 0:9b334a45a8ff 43
bogdanm 0:9b334a45a8ff 44 (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
bogdanm 0:9b334a45a8ff 45 and Mode(Receiver/Transmitter) in the hirda Init structure.
bogdanm 0:9b334a45a8ff 46
bogdanm 0:9b334a45a8ff 47 (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
bogdanm 0:9b334a45a8ff 48 (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
bogdanm 0:9b334a45a8ff 49 by calling the customed HAL_IRDA_MspInit() API.
bogdanm 0:9b334a45a8ff 50 -@@- The specific IRDA interrupts (Transmission complete interrupt,
bogdanm 0:9b334a45a8ff 51 RXNE interrupt and Error Interrupts) will be managed using the macros
bogdanm 0:9b334a45a8ff 52 __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
bogdanm 0:9b334a45a8ff 53
bogdanm 0:9b334a45a8ff 54 (#) Three operation modes are available within this driver :

bogdanm 0:9b334a45a8ff 183 This subsection provides a set of functions allowing to initialize the USARTx
bogdanm 0:9b334a45a8ff 184 in asynchronous IRDA mode.
bogdanm 0:9b334a45a8ff 185 (+) For the asynchronous mode only these parameters can be configured:

bogdanm 0:9b334a45a8ff 187 (++) Word Length
bogdanm 0:9b334a45a8ff 188 (++) Parity: If the parity is enabled, then the MSB bit of the data written
bogdanm 0:9b334a45a8ff 189 in the data register is transmitted but is changed by the parity bit.
bogdanm 0:9b334a45a8ff 190 Depending on the frame length defined by the M bit (8-bits or 9-bits)
bogdanm 0:9b334a45a8ff 191 or by the M1 and M0 bits (7-bit, 8-bit or 9-bit),

bogdanm 0:9b334a45a8ff 345 This subsection provides a set of functions allowing to manage the IRDA asynchronous
bogdanm 0:9b334a45a8ff 346 data transfers.
bogdanm 0:9b334a45a8ff 347
bogdanm 0:9b334a45a8ff 348 (#) There are two modes of transfer:
bogdanm 0:9b334a45a8ff 349 (++) Blocking mode: the communication is performed in polling mode.
bogdanm 0:9b334a45a8ff 350 The HAL status of all data processing is returned by the same function
bogdanm 0:9b334a45a8ff 351 after finishing transfer.
bogdanm 0:9b334a45a8ff 352 (++) No-Blocking mode: the communication is performed using Interrupts
bogdanm 0:9b334a45a8ff 353 or DMA, these API's return the HAL status.
bogdanm 0:9b334a45a8ff 354 The end of the data processing will be indicated through the
bogdanm 0:9b334a45a8ff 355 dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
bogdanm 0:9b334a45a8ff 356 using DMA mode.
bogdanm 0:9b334a45a8ff 357 The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
bogdanm 0:9b334a45a8ff 358 will be executed respectivelly at the end of the Transmit or Receive process
bogdanm 0:9b334a45a8ff 359 The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
bogdanm 0:9b334a45a8ff 360
bogdanm 0:9b334a45a8ff 361 (#) Blocking mode API's are :
bogdanm 0:9b334a45a8ff 362 (++) HAL_IRDA_Transmit()
bogdanm 0:9b334a45a8ff 363 (++) HAL_IRDA_Receive()
bogdanm 0:9b334a45a8ff 364
bogdanm 0:9b334a45a8ff 365 (#) Non-Blocking mode API's with Interrupt are :
bogdanm 0:9b334a45a8ff 366 (++) HAL_IRDA_Transmit_IT()
bogdanm 0:9b334a45a8ff 367 (++) HAL_IRDA_Receive_IT()
bogdanm 0:9b334a45a8ff 368 (++) HAL_IRDA_IRQHandler()

bogdanm 0:9b334a45a8ff 370 (++) IRDA_Receive_IT()
bogdanm 0:9b334a45a8ff 371
bogdanm 0:9b334a45a8ff 372 (#) Non-Blocking mode functions with DMA are :

bogdanm 0:9b334a45a8ff 374 (++) HAL_IRDA_Receive_DMA()
bogdanm 0:9b334a45a8ff 375
bogdanm 0:9b334a45a8ff 376 (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
bogdanm 0:9b334a45a8ff 377 (++) HAL_IRDA_TxCpltCallback()
