  ==============================================================================
                     ##### How to use this driver #####
  ==============================================================================
    [..]
      The SMARTCARD HAL driver can be used as follows:

    (#) Declare a SMARTCARD_HandleTypeDef handle structure.
    (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
        (##) Enable the interface clock of the USARTx associated to the SMARTCARD.
        (##) SMARTCARD pins configuration:
            (+++) Enable the clock for the SMARTCARD GPIOs.
            (+++) Configure SMARTCARD pins as alternate function pull-up.
        (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
             and HAL_SMARTCARD_Receive_IT() APIs):
            (+++) Configure the USARTx interrupt priority.
            (+++) Enable the NVIC USART IRQ handle.
        (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
             and HAL_SMARTCARD_Receive_DMA() APIs):
            (+++) Declare a DMA handle structure for the Tx/Rx channel.
            (+++) Enable the DMAx interface clock.
            (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
            (+++) Configure the DMA Tx/Rx channel.
            (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
            (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
                  (used for last byte sending completion detection in DMA non circular mode)

    (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware
        flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure.

    (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
        (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc)
             by calling the customized HAL_SMARTCARD_MspInit() API.
    [..]
    (@) The specific SMARTCARD interrupts (Transmission complete interrupt,
        RXNE interrupt and Error Interrupts) will be managed using the macros
        __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.

    [..]
    Three operation modes are available within this driver :

    *** Polling mode IO operation ***
    =================================
    [..]
      (+) Send an amount of data in blocking mode using HAL_SMARTCARD_Transmit()
      (+) Receive an amount of data in blocking mode using HAL_SMARTCARD_Receive()

    *** Interrupt mode IO operation ***
    ===================================
    [..]
      (+) Send an amount of data in non blocking mode using HAL_SMARTCARD_Transmit_IT()
      (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can
          add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
      (+) Receive an amount of data in non blocking mode using HAL_SMARTCARD_Receive_IT()
      (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can
          add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
      (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
          add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback

    *** DMA mode IO operation ***
    ==============================
    [..]
      (+) Send an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Transmit_DMA()
      (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can
          add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
      (+) Receive an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Receive_DMA()
      (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can
          add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
      (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
          add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback

    *** SMARTCARD HAL driver macros list ***
    ========================================
    [..]
      Below the list of most used macros in SMARTCARD HAL driver.

      (+) __HAL_SMARTCARD_ENABLE: Enable the SMARTCARD peripheral
      (+) __HAL_SMARTCARD_DISABLE: Disable the SMARTCARD peripheral
      (+) __HAL_SMARTCARD_GET_FLAG : Check whether the specified SMARTCARD flag is set or not
      (+) __HAL_SMARTCARD_CLEAR_FLAG : Clear the specified SMARTCARD pending flag
      (+) __HAL_SMARTCARD_ENABLE_IT: Enable the specified SMARTCARD interrupt
      (+) __HAL_SMARTCARD_DISABLE_IT: Disable the specified SMARTCARD interrupt

    [..]
      (@) You can refer to the SMARTCARD HAL driver header file for more useful macros

    ##### Callback registration #####
    ==================================

    [..]
    The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS when set to 1
    allows the user to configure dynamically the driver callbacks.

    [..]
    Use Function @ref HAL_SMARTCARD_RegisterCallback() to register a user callback.
    Function @ref HAL_SMARTCARD_RegisterCallback() allows to register following callbacks:
    (+) TxCpltCallback            : Tx Complete Callback.
    (+) RxCpltCallback            : Rx Complete Callback.
    (+) ErrorCallback             : Error Callback.
    (+) AbortCpltCallback         : Abort Complete Callback.
    (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
    (+) AbortReceiveCpltCallback  : Abort Receive Complete Callback.
    (+) MspInitCallback           : SMARTCARD MspInit.
    (+) MspDeInitCallback         : SMARTCARD MspDeInit.
    This function takes as parameters the HAL peripheral handle, the Callback ID
    and a pointer to the user callback function.

    [..]
    Use function @ref HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default
    weak (surcharged) function.
    @ref HAL_SMARTCARD_UnRegisterCallback() takes as parameters the HAL peripheral handle,
    and the Callback ID.
    This function allows to reset following callbacks:
    (+) TxCpltCallback            : Tx Complete Callback.
    (+) RxCpltCallback            : Rx Complete Callback.
    (+) ErrorCallback             : Error Callback.
    (+) AbortCpltCallback         : Abort Complete Callback.
    (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
    (+) AbortReceiveCpltCallback  : Abort Receive Complete Callback.
    (+) MspInitCallback           : SMARTCARD MspInit.
    (+) MspDeInitCallback         : SMARTCARD MspDeInit.

    [..]
    By default, after the @ref HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET
    all callbacks are set to the corresponding weak (surcharged) functions:
    examples @ref HAL_SMARTCARD_TxCpltCallback(), @ref HAL_SMARTCARD_RxCpltCallback().
    Exception done for MspInit and MspDeInit functions that are respectively
    reset to the legacy weak (surcharged) functions in the @ref HAL_SMARTCARD_Init()
    and @ref HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand).
    If not, MspInit or MspDeInit are not null, the @ref HAL_SMARTCARD_Init() and @ref HAL_SMARTCARD_DeInit()
    keep and use the user MspInit/MspDeInit callbacks (registered beforehand).

    [..]
    Callbacks can be registered/unregistered in HAL_SMARTCARD_STATE_READY state only.
    Exception done MspInit/MspDeInit that can be registered/unregistered
    in HAL_SMARTCARD_STATE_READY or HAL_SMARTCARD_STATE_RESET state, thus registered (user)
    MspInit/DeInit callbacks can be used during the Init/DeInit.
    In that case first register the MspInit/MspDeInit user callbacks
    using @ref HAL_SMARTCARD_RegisterCallback() before calling @ref HAL_SMARTCARD_DeInit()
    or @ref HAL_SMARTCARD_Init() function.

    [..]
    When The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS is set to 0 or
    not defined, the callback registration feature is not available
    and weak (surcharged) callbacks are used.

              ##### Initialization and Configuration functions #####
  ==============================================================================
  [..]
  This subsection provides a set of functions allowing to initialize the USART
  in Smartcard mode.
  [..]
  The Smartcard interface is designed to support asynchronous protocol Smartcards as
  defined in the ISO 7816-3 standard.
  [..]
  The USART can provide a clock to the smartcard through the SCLK output.
  In smartcard mode, SCLK is not associated to the communication but is simply derived
  from the internal peripheral input clock through a 5-bit prescaler.
  [..]
  (+) For the Smartcard mode only these parameters can be configured:
      (++) Baud Rate
      (++) Word Length => Should be 9 bits (8 bits + parity)
      (++) Stop Bit
      (++) Parity: => Should be enabled
      (++) USART polarity
      (++) USART phase
      (++) USART LastBit
      (++) Receiver/transmitter modes
      (++) Prescaler
      (++) GuardTime
      (++) NACKState: The Smartcard NACK state

     (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
        (++) Word Length = 9 Bits
        (++) 1.5 Stop Bit
        (++) Even parity
        (++) BaudRate = 12096 baud
        (++) Tx and Rx enabled
  [..]
  Please refer to the ISO 7816-3 specification for more details.

  [..]
   (@) It is also possible to choose 0.5 stop bit for receiving but it is recommended
       to use 1.5 stop bits for both transmitting and receiving to avoid switching
       between the two configurations.
  [..]
    The HAL_SMARTCARD_Init() function follows the USART  SmartCard configuration
    procedures (details for the procedures are available in reference manuals).

@endverbatim

  The SMARTCARD frame format is given in the following table:
       +-------------------------------------------------------------+
       |   M bit |  PCE bit  |        SMARTCARD frame                |
       |---------------------|---------------------------------------|
       |    1    |    1      |    | SB | 8 bit data | PB | STB |     |

 ===============================================================================
                      ##### 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, These APIs 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.
