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 (#) Declare a IRDA_HandleTypeDef handle structure.
bogdanm 0:9b334a45a8ff 25 (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API
bogdanm 0:9b334a45a8ff 26 in setting the associated USART or UART in IRDA mode:
bogdanm 0:9b334a45a8ff 27 (##) Enable the USARTx/UARTx interface clock.
bogdanm 0:9b334a45a8ff 28 (##) USARTx/UARTx pins configuration:
bogdanm 0:9b334a45a8ff 29 (+) Enable the clock for the USARTx/UARTx GPIOs.
bogdanm 0:9b334a45a8ff 30 (+) Configure these USARTx/UARTx 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/UARTx interrupt priority.
bogdanm 0:9b334a45a8ff 34 (+) Enable the NVIC IRDA IRQ handle.
bogdanm 0:9b334a45a8ff 35 (@) The specific IRDA interrupts (Transmission complete interrupt,
bogdanm 0:9b334a45a8ff 36 RXNE interrupt and Error Interrupts) will be managed using the macros
bogdanm 0:9b334a45a8ff 37 __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
bogdanm 0:9b334a45a8ff 38 (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
bogdanm 0:9b334a45a8ff 39 and HAL_IRDA_Receive_DMA() APIs):
bogdanm 0:9b334a45a8ff 40 (+) Declare a DMA handle structure for the Tx/Rx stream.
bogdanm 0:9b334a45a8ff 41 (+) Enable the DMAx interface clock.
bogdanm 0:9b334a45a8ff 42 (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
bogdanm 0:9b334a45a8ff 43 (+) Configure the DMA Tx/Rx Stream.
bogdanm 0:9b334a45a8ff 44 (+) Associate the initilalized DMA handle to the IRDA DMA Tx/Rx handle.
bogdanm 0:9b334a45a8ff 45 (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
bogdanm 0:9b334a45a8ff 46
bogdanm 0:9b334a45a8ff 47 (#) Program the Baud Rate, Word Length and Parity and Mode(Receiver/Transmitter),
bogdanm 0:9b334a45a8ff 48 the normal or low power mode and the clock prescaler in the hirda Init structure.
bogdanm 0:9b334a45a8ff 49
bogdanm 0:9b334a45a8ff 50 (#) Initialize the IRDA registers by calling
bogdanm 0:9b334a45a8ff 51 the HAL_IRDA_Init() API.
bogdanm 0:9b334a45a8ff 52
bogdanm 0:9b334a45a8ff 53 (@) This API (HAL_IRDA_Init()) configures also the low level Hardware (GPIO, CLOCK, CORTEX...etc)
bogdanm 0:9b334a45a8ff 54 by calling the customized HAL_IRDA_MspInit() API.

bogdanm 0:9b334a45a8ff 146 This subsection provides a set of functions allowing to initialize the USARTx
bogdanm 0:9b334a45a8ff 147 in asynchronous IRDA mode.
bogdanm 0:9b334a45a8ff 148 (+) For the asynchronous mode only these parameters can be configured:
bogdanm 0:9b334a45a8ff 149 (++) Baud Rate
bogdanm 0:9b334a45a8ff 150 (++) Word Length
bogdanm 0:9b334a45a8ff 151 (++) Parity: If the parity is enabled, then the MSB bit of the data written
bogdanm 0:9b334a45a8ff 152 in the data register is transmitted but is changed by the parity bit.
bogdanm 0:9b334a45a8ff 153 Depending on the frame length defined by the M bit (8-bits or 9-bits)
bogdanm 0:9b334a45a8ff 154 or by the M1 and M0 bits (7-bit, 8-bit or 9-bit),
bogdanm 0:9b334a45a8ff 155 the possible IRDA frame formats are as listed in the following table:

bogdanm 0:9b334a45a8ff 303 This subsection provides a set of functions allowing to manage the IRDA asynchronous
bogdanm 0:9b334a45a8ff 304 data transfers.
bogdanm 0:9b334a45a8ff 305
bogdanm 0:9b334a45a8ff 306 (#) There are two modes of transfer:
bogdanm 0:9b334a45a8ff 307 (+) Blocking mode: the communication is performed in polling mode.
bogdanm 0:9b334a45a8ff 308 The HAL status of all data processing is returned by the same function
bogdanm 0:9b334a45a8ff 309 after finishing transfer.
bogdanm 0:9b334a45a8ff 310 (+) No-Blocking mode: the communication is performed using Interrupts
bogdanm 0:9b334a45a8ff 311 or DMA, these API's return the HAL status.
bogdanm 0:9b334a45a8ff 312 The end of the data processing will be indicated through the
bogdanm 0:9b334a45a8ff 313 dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
bogdanm 0:9b334a45a8ff 314 using DMA mode.
bogdanm 0:9b334a45a8ff 315 The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
bogdanm 0:9b334a45a8ff 316 will be executed respectivelly at the end of the Transmit or Receive process
bogdanm 0:9b334a45a8ff 317 The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
bogdanm 0:9b334a45a8ff 318
bogdanm 0:9b334a45a8ff 319 (#) Blocking mode API's are :
bogdanm 0:9b334a45a8ff 320 (+) HAL_IRDA_Transmit()
bogdanm 0:9b334a45a8ff 321 (+) HAL_IRDA_Receive()
bogdanm 0:9b334a45a8ff 322
bogdanm 0:9b334a45a8ff 323 (#) Non-Blocking mode API's with Interrupt are :
bogdanm 0:9b334a45a8ff 324 (+) HAL_IRDA_Transmit_IT()
bogdanm 0:9b334a45a8ff 325 (+) HAL_IRDA_Receive_IT()
bogdanm 0:9b334a45a8ff 326 (+) HAL_IRDA_IRQHandler()
bogdanm 0:9b334a45a8ff 327 (+) IRDA_Transmit_IT()
bogdanm 0:9b334a45a8ff 328 (+) IRDA_Receive_IT()
bogdanm 0:9b334a45a8ff 329
bogdanm 0:9b334a45a8ff 330 (#) Non-Blocking mode functions with DMA are :
bogdanm 0:9b334a45a8ff 331 (+) HAL_IRDA_Transmit_DMA()
bogdanm 0:9b334a45a8ff 332 (+) HAL_IRDA_Receive_DMA()
bogdanm 0:9b334a45a8ff 333
bogdanm 0:9b334a45a8ff 334 (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
bogdanm 0:9b334a45a8ff 335 (+) HAL_IRDA_TxCpltCallback()
bogdanm 0:9b334a45a8ff 336 (+) HAL_IRDA_RxCpltCallback()
