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

    (#) Declare a SMARTCARD_HandleTypeDef handle structure (eg. SMARTCARD_HandleTypeDef hsmartcard).
    (#) Associate a USART to the SMARTCARD handle hsmartcard.
    (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
        (++) Enable the USARTx interface clock.
        (++) USART pins configuration:
             (+++) Enable the clock for the USART GPIOs.
             (+++) Configure the USART pins (TX as alternate function pull-up, RX as alternate function Input).
        (++) 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.

    (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
        the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
        error enabling or disabling in the hsmartcard handle Init structure.

    (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
        in the hsmartcard handle AdvancedInit structure.

    (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
        (++) This API configures 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_GET_FLAG : Check whether or not the specified SMARTCARD flag is set
       (+) __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
       (+) __HAL_SMARTCARD_GET_IT_SOURCE: Check whether or not the specified SMARTCARD interrupt is enabled

     [..]
       (@) 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 HAL_SMARTCARD_RegisterCallback() to register a user callback.
    Function 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 HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default
    weak (surcharged) function.
    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 HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET
    all callbacks are set to the corresponding weak (surcharged) functions:
    examples HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback().
    Exception done for MspInit and MspDeInit functions that are respectively
    reset to the legacy weak (surcharged) functions in the HAL_SMARTCARD_Init()
    and HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand).
    If not, MspInit or MspDeInit are not null, the HAL_SMARTCARD_Init() and 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 HAL_SMARTCARD_RegisterCallback() before calling HAL_SMARTCARD_DeInit()
    or 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.

  [..]
  This subsection provides a set of functions allowing to initialize the USARTx
  associated to the SmartCard.
  (+) These parameters can be configured:
      (++) Baud Rate
      (++) Parity: parity should be enabled, frame Length is fixed to 8 bits plus parity
      (++) Receiver/transmitter modes
      (++) Synchronous mode (and if enabled, phase, polarity and last bit parameters)
      (++) Prescaler value
      (++) Guard bit time
      (++) NACK enabling or disabling on transmission error

  (+) The following advanced features can be configured as well:
      (++) TX and/or RX pin level inversion
      (++) data logical level inversion
      (++) RX and TX pins swap
      (++) RX overrun detection disabling
      (++) DMA disabling on RX error
      (++) MSB first on communication line
      (++) Time out enabling (and if activated, timeout value)
      (++) Block length
      (++) Auto-retry counter
  [..]
  The HAL_SMARTCARD_Init() API follows the USART synchronous configuration procedures
  (details for the procedures are available in reference manual).

  ==============================================================================
                         ##### 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 transmission, 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.

  *           - Disable SMARTCARD Interrupts (Rx)
  *           - Disable the DMA transfer in the peripheral register (if enabled)
  *           - Abort DMA transfer by calling HAL_DMA_Abort_IT (in case of transfer in DMA mode)
  *           - Set handle State to READY
  *           - At abort completion, call user abort complete callback
  * @note   This procedure is executed in Interrupt mode, meaning that abort procedure could be
  *         considered as completed only when user abort complete callback is executed (not when exiting function).
