bogdanm	0:9b334a45a8ff	19	==============================================================================
bogdanm	0:9b334a45a8ff	20	[..]
bogdanm	0:9b334a45a8ff	21	The IRDA HAL driver can be used as follows:
bogdanm	0:9b334a45a8ff	22
bogdanm	0:9b334a45a8ff	23	(#) Declare a IRDA_HandleTypeDef handle structure (eg. IRDA_HandleTypeDef hirda).
bogdanm	0:9b334a45a8ff	24	(#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API
bogdanm	0:9b334a45a8ff	25	in setting the associated USART or UART in IRDA mode:
bogdanm	0:9b334a45a8ff	26	(++) Enable the USARTx/UARTx interface clock.
bogdanm	0:9b334a45a8ff	27	(++) USARTx/UARTx pins configuration:
bogdanm	0:9b334a45a8ff	28	(+++) Enable the clock for the USARTx/UARTx GPIOs.
bogdanm	0:9b334a45a8ff	29	(+++) Configure these USARTx/UARTx pins (TX as alternate function pull-up, RX as alternate function Input).
bogdanm	0:9b334a45a8ff	30	(++) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
bogdanm	0:9b334a45a8ff	31	and HAL_IRDA_Receive_IT() APIs):
bogdanm	0:9b334a45a8ff	32	(+++) Configure the USARTx/UARTx interrupt priority.
bogdanm	0:9b334a45a8ff	33	(+++) Enable the NVIC USARTx/UARTx IRQ handle.
bogdanm	0:9b334a45a8ff	34	(+++) The specific IRDA interrupts (Transmission complete interrupt,
bogdanm	0:9b334a45a8ff	35	RXNE interrupt and Error Interrupts) will be managed using the macros
bogdanm	0:9b334a45a8ff	36	__HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
bogdanm	0:9b334a45a8ff	37
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 channel.
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 channel.
bogdanm	0:9b334a45a8ff	44	(+++) Associate the initialized 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 channel.
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 handle Init structure.
bogdanm	0:9b334a45a8ff	49
bogdanm	0:9b334a45a8ff	50	(#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
bogdanm	0:9b334a45a8ff	51	(++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
bogdanm	0:9b334a45a8ff	52	by calling the customized HAL_IRDA_MspInit() API.

bogdanm	0:9b334a45a8ff	384	[..]
bogdanm	0:9b334a45a8ff	385	IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
bogdanm	0:9b334a45a8ff	386	on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
bogdanm	0:9b334a45a8ff	387	is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
bogdanm	0:9b334a45a8ff	388	While receiving data, transmission should be avoided as the data to be transmitted
bogdanm	0:9b334a45a8ff	389	could be corrupted.

bogdanm	0:9b334a45a8ff	393	The HAL status of all data processing is returned by the same function
bogdanm	0:9b334a45a8ff	394	after finishing transfer.
bogdanm	0:9b334a45a8ff	395	(++) No-Blocking mode: the communication is performed using Interrupts
bogdanm	0:9b334a45a8ff	396	or DMA, these API's return the HAL status.
bogdanm	0:9b334a45a8ff	397	The end of the data processing will be indicated through the
