Detailed Description

SMARTCARD Transmit and Receive functions. 

  ==============================================================================
                         ##### IO operation functions #####
  ==============================================================================
  [..]
    This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.

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

  [..]
    (+) There are two modes of transfer:
        (++) Blocking mode: The communication is performed in polling mode.
             The HAL status of all data processing is returned by the same function
             after finishing transfer.
        (++) Non-Blocking mode: The communication is performed using Interrupts
             or DMA, the relevant API's return the HAL status.
             The end of the data processing will be indicated through the
             dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
             using DMA mode.
        (++) The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
             will be executed respectively at the end of the Transmit or Receive process
             The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication
             error is detected.

    (+) Blocking mode APIs are :
        (++) HAL_SMARTCARD_Transmit()
        (++) HAL_SMARTCARD_Receive()

    (+) Non Blocking mode APIs with Interrupt are :
        (++) HAL_SMARTCARD_Transmit_IT()
        (++) HAL_SMARTCARD_Receive_IT()
        (++) HAL_SMARTCARD_IRQHandler()

    (+) Non Blocking mode functions with DMA are :
        (++) HAL_SMARTCARD_Transmit_DMA()
        (++) HAL_SMARTCARD_Receive_DMA()

    (+) A set of Transfer Complete Callbacks are provided in non Blocking mode:
        (++) HAL_SMARTCARD_TxCpltCallback()
        (++) HAL_SMARTCARD_RxCpltCallback()
        (++) HAL_SMARTCARD_ErrorCallback()

    (#) Non-Blocking mode transfers could be aborted using Abort API's :
        (+) HAL_SMARTCARD_Abort()
        (+) HAL_SMARTCARD_AbortTransmit()
        (+) HAL_SMARTCARD_AbortReceive()
        (+) HAL_SMARTCARD_Abort_IT()
        (+) HAL_SMARTCARD_AbortTransmit_IT()
        (+) HAL_SMARTCARD_AbortReceive_IT()

    (#) For Abort services based on interrupts (HAL_SMARTCARD_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
        (+) HAL_SMARTCARD_AbortCpltCallback()
        (+) HAL_SMARTCARD_AbortTransmitCpltCallback()
        (+) HAL_SMARTCARD_AbortReceiveCpltCallback()

    (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
        Errors are handled as follows :
       (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
           to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
           Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
           and HAL_SMARTCARD_ErrorCallback() user callback is executed. Transfer is kept ongoing on SMARTCARD side.
           If user wants to abort it, Abort services should be called by user.
       (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
           This concerns Frame Error in Interrupt mode tranmission, Overrun Error in Interrupt mode reception and all errors in DMA mode.
           Error code is set to allow user to identify error type, and HAL_SMARTCARD_ErrorCallback() user callback is executed.

HAL_StatusTypeDef HAL_SMARTCARD_Abort ( SMARTCARD_HandleTypeDef *  hsmartcard)

Abort ongoing transfers (blocking mode).

Parameters:
hsmartcardPointer to a SMARTCARD_HandleTypeDef structure that contains the configuration information for the specified SMARTCARD module.

HAL_StatusTypeDef HAL_SMARTCARD_Receive_IT ( SMARTCARD_HandleTypeDef *  hsmartcard,

Note:
When FIFO mode is disabled, USART interrupt is generated whenever USART_RDR register can be read, i.e one interrupt per data to receive.
When FIFO mode is enabled, USART interrupt is generated whenever RXFIFO threshold reached. In that case the interrupt rate depends on RXFIFO threshold configuration.
This function sets the hsmartcard->RxIsr function pointer according to the FIFO mode (data reception processing depends on FIFO mode).

uint8_t *  pData,
uint16_t  Size,
uint32_t  Timeout 
)

Send an amount of data in blocking mode.

Note:
When FIFO mode is enabled, writing a data in the TDR register adds one data to the TXFIFO. Write operations to the TDR register are performed when TXFNF flag is set. From hardware perspective, TXFNF flag and TXE are mapped on the same bit-field.
Parameters:
hsmartcardPointer to a SMARTCARD_HandleTypeDef structure that contains the configuration information for the specified SMARTCARD module.
