<> 144:ef7eb2e8f9f7 20 The SMARTCARD HAL driver can be used as follows:
<> 144:ef7eb2e8f9f7 21
<> 144:ef7eb2e8f9f7 22 (#) Declare a SMARTCARD_HandleTypeDef handle structure (eg. SMARTCARD_HandleTypeDef hsmartcard).
<> 144:ef7eb2e8f9f7 23 (#) Associate a USART to the SMARTCARD handle hsmartcard.
<> 144:ef7eb2e8f9f7 24 (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
<> 144:ef7eb2e8f9f7 25 (++) Enable the USARTx interface clock.
<> 144:ef7eb2e8f9f7 26 (++) USART pins configuration:
<> 144:ef7eb2e8f9f7 27 (+++) Enable the clock for the USART GPIOs.
<> 144:ef7eb2e8f9f7 28 (+++) Configure the USART pins (TX as alternate function pull-up, RX as alternate function Input).
<> 144:ef7eb2e8f9f7 29 (++) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
<> 144:ef7eb2e8f9f7 30 and HAL_SMARTCARD_Receive_IT() APIs):
<> 144:ef7eb2e8f9f7 31 (+++) Configure the USARTx interrupt priority.
<> 144:ef7eb2e8f9f7 32 (+++) Enable the NVIC USART IRQ handle.

<> 144:ef7eb2e8f9f7 38 (+++) Configure the DMA Tx/Rx channel.
<> 144:ef7eb2e8f9f7 39 (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.

<> 144:ef7eb2e8f9f7 47 in the hsmartcard handle AdvancedInit structure.
<> 144:ef7eb2e8f9f7 48
<> 144:ef7eb2e8f9f7 49 (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:

<> 144:ef7eb2e8f9f7 404 [..]
<> 144:ef7eb2e8f9f7 405 Smartcard is a single wire half duplex communication protocol.
<> 144:ef7eb2e8f9f7 406 The Smartcard interface is designed to support asynchronous protocol Smartcards as
<> 144:ef7eb2e8f9f7 407 defined in the ISO 7816-3 standard. The USART should be configured as:
<> 144:ef7eb2e8f9f7 408 (+) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
<> 144:ef7eb2e8f9f7 409 (+) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.

<> 144:ef7eb2e8f9f7 411 [..]
<> 144:ef7eb2e8f9f7 412 (+) There are two modes of transfer:
<> 144:ef7eb2e8f9f7 413 (++) Blocking mode: The communication is performed in polling mode.
<> 144:ef7eb2e8f9f7 414 The HAL status of all data processing is returned by the same function
<> 144:ef7eb2e8f9f7 415 after finishing transfer.
<> 144:ef7eb2e8f9f7 416 (++) No-Blocking mode: The communication is performed using Interrupts
<> 144:ef7eb2e8f9f7 417 or DMA, the relevant API's return the HAL status.
<> 144:ef7eb2e8f9f7 418 The end of the data processing will be indicated through the
