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 180 (+) For the asynchronous mode only these parameters can be configured:

bogdanm 0:9b334a45a8ff 331 This subsection provides a set of functions allowing to manage the IRDA asynchronous
bogdanm 0:9b334a45a8ff 332 data transfers.
bogdanm 0:9b334a45a8ff 333
bogdanm 0:9b334a45a8ff 334 (#) There are two modes of transfer:
bogdanm 0:9b334a45a8ff 335 (++) Blocking mode: the communication is performed in polling mode.
bogdanm 0:9b334a45a8ff 336 The HAL status of all data processing is returned by the same function
bogdanm 0:9b334a45a8ff 337 after finishing transfer.
bogdanm 0:9b334a45a8ff 338 (++) No-Blocking mode: the communication is performed using Interrupts
bogdanm 0:9b334a45a8ff 339 or DMA, these API's return the HAL status.
bogdanm 0:9b334a45a8ff 340 The end of the data processing will be indicated through the
bogdanm 0:9b334a45a8ff 341 dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
bogdanm 0:9b334a45a8ff 342 using DMA mode.
bogdanm 0:9b334a45a8ff 343 The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
bogdanm 0:9b334a45a8ff 344 will be executed respectivelly at the end of the Transmit or Receive process
bogdanm 0:9b334a45a8ff 345 The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
bogdanm 0:9b334a45a8ff 346
bogdanm 0:9b334a45a8ff 347 (#) Blocking mode API's are :
bogdanm 0:9b334a45a8ff 348 (++) HAL_IRDA_Transmit()
bogdanm 0:9b334a45a8ff 349 (++) HAL_IRDA_Receive()
bogdanm 0:9b334a45a8ff 350
bogdanm 0:9b334a45a8ff 351 (#) Non-Blocking mode API's with Interrupt are :
bogdanm 0:9b334a45a8ff 352 (++) HAL_IRDA_Transmit_IT()
bogdanm 0:9b334a45a8ff 353 (++) HAL_IRDA_Receive_IT()

bogdanm 0:9b334a45a8ff 358 (#) Non-Blocking mode functions with DMA are :
