mbed_official	237:f3da66175598	19	##### How to use this driver #####
mbed_official	237:f3da66175598	20	===============================================================================
mbed_official	237:f3da66175598	21	[..]
mbed_official	237:f3da66175598	22	The IRDA HAL driver can be used as follows:
mbed_official	237:f3da66175598	23
mbed_official	237:f3da66175598	24	(#) Declare a IRDA_HandleTypeDef handle structure.
mbed_official	237:f3da66175598	25	(#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API
mbed_official	237:f3da66175598	26	in setting the associated USART or UART in IRDA mode:
mbed_official	237:f3da66175598	27	(##) Enable the USARTx/UARTx interface clock.
mbed_official	237:f3da66175598	28	(##) USARTx/UARTx pins configuration:
mbed_official	237:f3da66175598	29	(+) Enable the clock for the USARTx/UARTx GPIOs.
mbed_official	237:f3da66175598	30	(+) Configure these USARTx/UARTx pins as alternate function pull-up.
mbed_official	237:f3da66175598	31	(##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
mbed_official	237:f3da66175598	32	and HAL_IRDA_Receive_IT() APIs):
mbed_official	237:f3da66175598	33	(+) Configure the USARTx/UARTx interrupt priority.
mbed_official	237:f3da66175598	34	(+) Enable the NVIC IRDA IRQ handle.
mbed_official	237:f3da66175598	35	(@) The specific IRDA interrupts (Transmission complete interrupt,
mbed_official	237:f3da66175598	36	RXNE interrupt and Error Interrupts) will be managed using the macros
mbed_official	237:f3da66175598	37	__HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
mbed_official	237:f3da66175598	38	(##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
mbed_official	237:f3da66175598	39	and HAL_IRDA_Receive_DMA() APIs):
mbed_official	237:f3da66175598	40	(+) Declare a DMA handle structure for the Tx/Rx stream.
mbed_official	237:f3da66175598	41	(+) Enable the DMAx interface clock.
mbed_official	237:f3da66175598	42	(+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
mbed_official	237:f3da66175598	43	(+) Configure the DMA Tx/Rx Stream.
mbed_official	237:f3da66175598	44	(+) Associate the initilalized DMA handle to the IRDA DMA Tx/Rx handle.
mbed_official	237:f3da66175598	45	(+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
mbed_official	237:f3da66175598	46
mbed_official	237:f3da66175598	47	(#) Program the Baud Rate, Word Length and Parity and Mode(Receiver/Transmitter),
mbed_official	237:f3da66175598	48	the normal or low power mode and the clock prescaler in the hirda Init structure.
mbed_official	237:f3da66175598	49
mbed_official	237:f3da66175598	50	(#) Initialize the IRDA registers by calling
mbed_official	237:f3da66175598	51	the HAL_IRDA_Init() API.
mbed_official	237:f3da66175598	52
mbed_official	237:f3da66175598	53	(@) This API (HAL_IRDA_Init()) configures also the low level Hardware (GPIO, CLOCK, CORTEX...etc)
mbed_official	237:f3da66175598	54	by calling the customized HAL_IRDA_MspInit() API.
