bogdanm	0:9b334a45a8ff	17	##### How to use this driver #####
bogdanm	0:9b334a45a8ff	18	==============================================================================
bogdanm	0:9b334a45a8ff	19	[..]
bogdanm	0:9b334a45a8ff	20	The SMARTCARD HAL driver can be used as follows:
bogdanm	0:9b334a45a8ff	21
bogdanm	0:9b334a45a8ff	22	(#) Declare a SMARTCARD_HandleTypeDef handle structure (eg. SMARTCARD_HandleTypeDef hsmartcard).
bogdanm	0:9b334a45a8ff	23	(#) Associate a USART to the SMARTCARD handle hsmartcard.
bogdanm	0:9b334a45a8ff	24	(#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
bogdanm	0:9b334a45a8ff	25	(++) Enable the USARTx interface clock.
bogdanm	0:9b334a45a8ff	26	(++) USART pins configuration:
bogdanm	0:9b334a45a8ff	27	(+++) Enable the clock for the USART GPIOs.
bogdanm	0:9b334a45a8ff	28	(+++) Configure the USART pins (TX as alternate function pull-up, RX as alternate function Input).
bogdanm	0:9b334a45a8ff	29	(++) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
bogdanm	0:9b334a45a8ff	30	and HAL_SMARTCARD_Receive_IT() APIs):
bogdanm	0:9b334a45a8ff	31	(+++) Configure the USARTx interrupt priority.
bogdanm	0:9b334a45a8ff	32	(+++) Enable the NVIC USART IRQ handle.
bogdanm	0:9b334a45a8ff	33	(++) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
bogdanm	0:9b334a45a8ff	34	and HAL_SMARTCARD_Receive_DMA() APIs):
bogdanm	0:9b334a45a8ff	35	(+++) Declare a DMA handle structure for the Tx/Rx channel.
bogdanm	0:9b334a45a8ff	36	(+++) Enable the DMAx interface clock.
bogdanm	0:9b334a45a8ff	37	(+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
bogdanm	0:9b334a45a8ff	38	(+++) Configure the DMA Tx/Rx channel.
bogdanm	0:9b334a45a8ff	39	(+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
bogdanm	0:9b334a45a8ff	40	(+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
bogdanm	0:9b334a45a8ff	41
bogdanm	0:9b334a45a8ff	42	(#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
bogdanm	0:9b334a45a8ff	43	the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
bogdanm	0:9b334a45a8ff	44	error enabling or disabling in the hsmartcard handle Init structure.
bogdanm	0:9b334a45a8ff	45
bogdanm	0:9b334a45a8ff	46	(#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
bogdanm	0:9b334a45a8ff	47	in the hsmartcard handle AdvancedInit structure.
bogdanm	0:9b334a45a8ff	48
bogdanm	0:9b334a45a8ff	49	(#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
bogdanm	0:9b334a45a8ff	50	(++) This API configures also the low level Hardware (GPIO, CLOCK, CORTEX...etc)
bogdanm	0:9b334a45a8ff	51	by calling the customized HAL_SMARTCARD_MspInit() API.
bogdanm	0:9b334a45a8ff	52	[..]
bogdanm	0:9b334a45a8ff	53	(@) The specific SMARTCARD interrupts (Transmission complete interrupt,
bogdanm	0:9b334a45a8ff	54	RXNE interrupt and Error Interrupts) will be managed using the macros
bogdanm	0:9b334a45a8ff	55	__HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
