ganlikun	0:13413ea9a877	19	The SMARTCARD HAL driver can be used as follows:
ganlikun	0:13413ea9a877	20
ganlikun	0:13413ea9a877	21	(#) Declare a SMARTCARD_HandleTypeDef handle structure.
ganlikun	0:13413ea9a877	22	(#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
ganlikun	0:13413ea9a877	23	(##) Enable the USARTx interface clock.

ganlikun	0:13413ea9a877	189	[..]
ganlikun	0:13413ea9a877	190	The Smartcard interface is designed to support asynchronous protocol Smartcards as
ganlikun	0:13413ea9a877	191	defined in the ISO 7816-3 standard.
ganlikun	0:13413ea9a877	192	[..]
ganlikun	0:13413ea9a877	193	The USART can provide a clock to the smartcard through the SCLK output.
ganlikun	0:13413ea9a877	194	In smartcard mode, SCLK is not associated to the communication but is simply derived
ganlikun	0:13413ea9a877	195	from the internal peripheral input clock through a 5-bit prescaler.
ganlikun	0:13413ea9a877	196	[..]

ganlikun	0:13413ea9a877	220	(@) It is also possible to choose 0.5 stop bit for receiving but it is recommended
ganlikun	0:13413ea9a877	221	to use 1.5 stop bits for both transmitting and receiving to avoid switching
ganlikun	0:13413ea9a877	222	between the two configurations.

ganlikun	0:13413ea9a877	383	[..]
ganlikun	0:13413ea9a877	384	(#) Smartcard is a single wire half duplex communication protocol.
ganlikun	0:13413ea9a877	385	The Smartcard interface is designed to support asynchronous protocol Smartcards as
ganlikun	0:13413ea9a877	386	defined in the ISO 7816-3 standard.
ganlikun	0:13413ea9a877	387	(#) The USART should be configured as:
ganlikun	0:13413ea9a877	388	(++) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
ganlikun	0:13413ea9a877	389	(++) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.

ganlikun	0:13413ea9a877	392	(++) Blocking mode: The communication is performed in polling mode.
ganlikun	0:13413ea9a877	393	The HAL status of all data processing is returned by the same function
ganlikun	0:13413ea9a877	394	after finishing transfer.
ganlikun	0:13413ea9a877	395	(++) Non Blocking mode: The communication is performed using Interrupts
ganlikun	0:13413ea9a877	396	or DMA, These APIs return the HAL status.
ganlikun	0:13413ea9a877	397	The end of the data processing will be indicated through the
ganlikun	0:13413ea9a877	398	dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
ganlikun	0:13413ea9a877	399	using DMA mode.
