|
|
|
+ ##### 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_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

|
|
|
+ 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
|
|
|
+ [..]
|
|
|

|
|

+ 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.
