- * @brief SMARTCARD HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the SMARTCARD peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State and Errors functions
- *
- @verbatim
- ==============================================================================
- ##### 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 USARTx interface clock.
- (##) SMARTCARD pins configuration:
- (+++) Enable the clock for the SMARTCARD GPIOs.
- (+++) Configure these 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 stream.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx Stream.
- (+++) 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 Stream.
-
- (#) 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

- ##### 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
- procedure (details for the procedure are available in reference manual (RM0329)).
-
- @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 | |
