phungductung	0:8ede47d38d10	18	[..]
phungductung	0:8ede47d38d10	19	The SMARTCARD HAL driver can be used as follow:
phungductung	0:8ede47d38d10	20
phungductung	0:8ede47d38d10	21	(#) Declare a SMARTCARD_HandleTypeDef handle structure.
phungductung	0:8ede47d38d10	22	(#) Associate a USART to the SMARTCARD handle hsc.
phungductung	0:8ede47d38d10	23	(#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
phungductung	0:8ede47d38d10	24	(##) Enable the USARTx interface clock.

phungductung	0:8ede47d38d10	311	This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
phungductung	0:8ede47d38d10	312
phungductung	0:8ede47d38d10	313	(#) There are two modes of transfer:
phungductung	0:8ede47d38d10	314	(+) Blocking mode: The communication is performed in polling mode.
phungductung	0:8ede47d38d10	315	The HAL status of all data processing is returned by the same function
phungductung	0:8ede47d38d10	316	after finishing transfer.
phungductung	0:8ede47d38d10	317	(+) No-Blocking mode: The communication is performed using Interrupts
phungductung	0:8ede47d38d10	318	or DMA, These API's return the HAL status.
phungductung	0:8ede47d38d10	319	The end of the data processing will be indicated through the
phungductung	0:8ede47d38d10	320	dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
phungductung	0:8ede47d38d10	321	using DMA mode.
phungductung	0:8ede47d38d10	322	The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
phungductung	0:8ede47d38d10	323	will be executed respectively at the end of the Transmit or Receive process
phungductung	0:8ede47d38d10	324	The HAL_SMARTCARD_ErrorCallback()user callback will be executed when a communication error is detected
phungductung	0:8ede47d38d10	325
phungductung	0:8ede47d38d10	326	(#) Blocking mode API's are :
phungductung	0:8ede47d38d10	327	(+) HAL_SMARTCARD_Transmit()
phungductung	0:8ede47d38d10	328	(+) HAL_SMARTCARD_Receive()
phungductung	0:8ede47d38d10	329
phungductung	0:8ede47d38d10	330	(#) Non-Blocking mode API's with Interrupt are :
phungductung	0:8ede47d38d10	331	(+) HAL_SMARTCARD_Transmit_IT()
phungductung	0:8ede47d38d10	332	(+) HAL_SMARTCARD_Receive_IT()

phungductung	0:8ede47d38d10	341	(#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
