- ==============================================================================
- ##### 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

-

- 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.
- (++) No-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()
