- ==============================================================================
- ##### 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 @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.
- (+) RxFifoFullCallback : Rx Fifo Full Callback.
- (+) TxFifoEmptyCallback : Tx Fifo Empty 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.
- (+) RxFifoFullCallback : Rx Fifo Full Callback.
- (+) TxFifoEmptyCallback : Tx Fifo Empty 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.

- [..]
- 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 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.
