phungductung	0:e87aa4c49e95	17	==============================================================================
phungductung	0:e87aa4c49e95	18	[..]
phungductung	0:e87aa4c49e95	19	The SMARTCARD HAL driver can be used as follow:
phungductung	0:e87aa4c49e95	20
phungductung	0:e87aa4c49e95	21	(#) Declare a SMARTCARD_HandleTypeDef handle structure.
phungductung	0:e87aa4c49e95	22	(#) Associate a USART to the SMARTCARD handle hsc.
phungductung	0:e87aa4c49e95	23	(#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
phungductung	0:e87aa4c49e95	24	(##) Enable the USARTx interface clock.
phungductung	0:e87aa4c49e95	25	(##) SMARTCARD pins configuration:
phungductung	0:e87aa4c49e95	26	(+++) Enable the clock for the SMARTCARD GPIOs.
phungductung	0:e87aa4c49e95	27	(+++) Configure these SMARTCARD pins as alternate function pull-up.

phungductung	0:e87aa4c49e95	31	(+++) Enable the NVIC USART IRQ handle.

phungductung	0:e87aa4c49e95	33	RXNE interrupt and Error Interrupts) will be managed using the macros
phungductung	0:e87aa4c49e95	34	__HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
phungductung	0:e87aa4c49e95	35	(##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()

phungductung	0:e87aa4c49e95	44	(#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
phungductung	0:e87aa4c49e95	45	the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
phungductung	0:e87aa4c49e95	46	error enabling or disabling in the hsc Init structure.

phungductung	0:e87aa4c49e95	311	This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
phungductung	0:e87aa4c49e95	312
phungductung	0:e87aa4c49e95	313	(#) There are two modes of transfer:
phungductung	0:e87aa4c49e95	314	(+) Blocking mode: The communication is performed in polling mode.
phungductung	0:e87aa4c49e95	315	The HAL status of all data processing is returned by the same function
phungductung	0:e87aa4c49e95	316	after finishing transfer.
phungductung	0:e87aa4c49e95	317	(+) No-Blocking mode: The communication is performed using Interrupts
phungductung	0:e87aa4c49e95	318	or DMA, These API's return the HAL status.
phungductung	0:e87aa4c49e95	319	The end of the data processing will be indicated through the
phungductung	0:e87aa4c49e95	320	dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
phungductung	0:e87aa4c49e95	321	using DMA mode.
phungductung	0:e87aa4c49e95	322	The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
phungductung	0:e87aa4c49e95	323	will be executed respectively at the end of the Transmit or Receive process
phungductung	0:e87aa4c49e95	324	The HAL_SMARTCARD_ErrorCallback()user callback will be executed when a communication error is detected
phungductung	0:e87aa4c49e95	325
phungductung	0:e87aa4c49e95	326	(#) Blocking mode API's are :
