bogdanm	0:9b334a45a8ff	18	==============================================================================
bogdanm	0:9b334a45a8ff	19	[..]
bogdanm	0:9b334a45a8ff	20	The IRDA HAL driver can be used as follows:
bogdanm	0:9b334a45a8ff	21
bogdanm	0:9b334a45a8ff	22	(#) Declare a IRDA_HandleTypeDef handle structure.
bogdanm	0:9b334a45a8ff	23	(#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
bogdanm	0:9b334a45a8ff	24	(##) Enable the USARTx interface clock.
bogdanm	0:9b334a45a8ff	25	(##) IRDA pins configuration:
bogdanm	0:9b334a45a8ff	26	(+++) Enable the clock for the IRDA GPIOs.
bogdanm	0:9b334a45a8ff	27	(+++) Configure the USART pins (TX as alternate function pull-up, RX as alternate function Input).
bogdanm	0:9b334a45a8ff	28	(##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
bogdanm	0:9b334a45a8ff	29	and HAL_IRDA_Receive_IT() APIs):
bogdanm	0:9b334a45a8ff	30	(+++) Configure the USARTx interrupt priority.
bogdanm	0:9b334a45a8ff	31	(+++) Enable the NVIC USART IRQ handle.
bogdanm	0:9b334a45a8ff	32	(##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
bogdanm	0:9b334a45a8ff	33	and HAL_IRDA_Receive_DMA() APIs):
bogdanm	0:9b334a45a8ff	34	(+++) Declare a DMA handle structure for the Tx/Rx channel.
bogdanm	0:9b334a45a8ff	35	(+++) Enable the DMAx interface clock.
bogdanm	0:9b334a45a8ff	36	(+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
bogdanm	0:9b334a45a8ff	37	(+++) Configure the DMA Tx/Rx channel.
bogdanm	0:9b334a45a8ff	38	(+++) Associate the initilalized DMA handle to the IRDA DMA Tx/Rx handle.
bogdanm	0:9b334a45a8ff	39	(+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
bogdanm	0:9b334a45a8ff	40	(+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
bogdanm	0:9b334a45a8ff	41	(used for last byte sending completion detection in DMA non circular mode)
bogdanm	0:9b334a45a8ff	42
bogdanm	0:9b334a45a8ff	43	(#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
bogdanm	0:9b334a45a8ff	44	and Mode(Receiver/Transmitter) in the hirda Init structure.
bogdanm	0:9b334a45a8ff	45
bogdanm	0:9b334a45a8ff	46	(#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
bogdanm	0:9b334a45a8ff	47	(++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
bogdanm	0:9b334a45a8ff	48	by calling the customed HAL_IRDA_MspInit() API.
bogdanm	0:9b334a45a8ff	49
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	377	[..]
bogdanm	0:9b334a45a8ff	378	IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
bogdanm	0:9b334a45a8ff	379	on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
bogdanm	0:9b334a45a8ff	380	is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
bogdanm	0:9b334a45a8ff	381	While receiving data, transmission should be avoided as the data to be transmitted
bogdanm	0:9b334a45a8ff	382	could be corrupted.

bogdanm	0:9b334a45a8ff	386	The HAL status of all data processing is returned by the same function
bogdanm	0:9b334a45a8ff	387	after finishing transfer.
bogdanm	0:9b334a45a8ff	388	(++) No-Blocking mode: The communication is performed using Interrupts
bogdanm	0:9b334a45a8ff	389	or DMA, These API's return the HAL status.
bogdanm	0:9b334a45a8ff	390	The end of the data processing will be indicated through the
bogdanm	0:9b334a45a8ff	391	dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
bogdanm	0:9b334a45a8ff	392	using DMA mode.
