NYX 0:85b3fd62ea1a 16 ##### How to use this driver #####
NYX 0:85b3fd62ea1a 17 ==============================================================================
NYX 0:85b3fd62ea1a 18 [..]
NYX 0:85b3fd62ea1a 19 The SMARTCARD HAL driver can be used as follows:
NYX 0:85b3fd62ea1a 20
NYX 0:85b3fd62ea1a 21 (#) Declare a SMARTCARD_HandleTypeDef handle structure.
NYX 0:85b3fd62ea1a 22 (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
NYX 0:85b3fd62ea1a 23 (##) Enable the USARTx interface clock.
NYX 0:85b3fd62ea1a 24 (##) SMARTCARD pins configuration:
NYX 0:85b3fd62ea1a 25 (+++) Enable the clock for the SMARTCARD GPIOs.
NYX 0:85b3fd62ea1a 26 (+++) Configure these SMARTCARD pins as alternate function pull-up.
NYX 0:85b3fd62ea1a 27 (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
NYX 0:85b3fd62ea1a 28 and HAL_SMARTCARD_Receive_IT() APIs):
NYX 0:85b3fd62ea1a 29 (+++) Configure the USARTx interrupt priority.
NYX 0:85b3fd62ea1a 30 (+++) Enable the NVIC USART IRQ handle.
NYX 0:85b3fd62ea1a 31 (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
NYX 0:85b3fd62ea1a 32 and HAL_SMARTCARD_Receive_DMA() APIs):
NYX 0:85b3fd62ea1a 33 (+++) Declare a DMA handle structure for the Tx/Rx stream.
NYX 0:85b3fd62ea1a 34 (+++) Enable the DMAx interface clock.
NYX 0:85b3fd62ea1a 35 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
NYX 0:85b3fd62ea1a 36 (+++) Configure the DMA Tx/Rx Stream.
NYX 0:85b3fd62ea1a 37 (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
NYX 0:85b3fd62ea1a 38 (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
NYX 0:85b3fd62ea1a 39
NYX 0:85b3fd62ea1a 40 (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware
NYX 0:85b3fd62ea1a 41 flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure.
NYX 0:85b3fd62ea1a 42
NYX 0:85b3fd62ea1a 43 (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
NYX 0:85b3fd62ea1a 44 (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc)
NYX 0:85b3fd62ea1a 45 by calling the customized HAL_SMARTCARD_MspInit() API.
NYX 0:85b3fd62ea1a 46 [..]
NYX 0:85b3fd62ea1a 47 (@) The specific SMARTCARD interrupts (Transmission complete interrupt,
NYX 0:85b3fd62ea1a 48 RXNE interrupt and Error Interrupts) will be managed using the macros
NYX 0:85b3fd62ea1a 49 __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
NYX 0:85b3fd62ea1a 50
NYX 0:85b3fd62ea1a 51 [..]
NYX 0:85b3fd62ea1a 52 Three operation modes are available within this driver :

NYX 0:85b3fd62ea1a 186 [..]
NYX 0:85b3fd62ea1a 187 This subsection provides a set of functions allowing to initialize the USART
NYX 0:85b3fd62ea1a 188 in Smartcard mode.
NYX 0:85b3fd62ea1a 189 [..]
NYX 0:85b3fd62ea1a 190 The Smartcard interface is designed to support asynchronous protocol Smartcards as
NYX 0:85b3fd62ea1a 191 defined in the ISO 7816-3 standard.
NYX 0:85b3fd62ea1a 192 [..]
NYX 0:85b3fd62ea1a 193 The USART can provide a clock to the smartcard through the SCLK output.
NYX 0:85b3fd62ea1a 194 In smartcard mode, SCLK is not associated to the communication but is simply derived
NYX 0:85b3fd62ea1a 195 from the internal peripheral input clock through a 5-bit prescaler.
NYX 0:85b3fd62ea1a 196 [..]
NYX 0:85b3fd62ea1a 197 (+) For the Smartcard mode only these parameters can be configured:
NYX 0:85b3fd62ea1a 198 (++) Baud Rate
NYX 0:85b3fd62ea1a 199 (++) Word Length => Should be 9 bits (8 bits + parity)
NYX 0:85b3fd62ea1a 200 (++) Stop Bit
NYX 0:85b3fd62ea1a 201 (++) Parity: => Should be enabled
NYX 0:85b3fd62ea1a 202 (++) USART polarity
NYX 0:85b3fd62ea1a 203 (++) USART phase
NYX 0:85b3fd62ea1a 204 (++) USART LastBit
NYX 0:85b3fd62ea1a 205 (++) Receiver/transmitter modes
NYX 0:85b3fd62ea1a 206 (++) Prescaler
NYX 0:85b3fd62ea1a 207 (++) GuardTime
NYX 0:85b3fd62ea1a 208 (++) NACKState: The Smartcard NACK state
NYX 0:85b3fd62ea1a 209
NYX 0:85b3fd62ea1a 210 (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
NYX 0:85b3fd62ea1a 211 (++) Word Length = 9 Bits
NYX 0:85b3fd62ea1a 212 (++) 1.5 Stop Bit
NYX 0:85b3fd62ea1a 213 (++) Even parity
NYX 0:85b3fd62ea1a 214 (++) BaudRate = 12096 baud
NYX 0:85b3fd62ea1a 215 (++) Tx and Rx enabled
NYX 0:85b3fd62ea1a 216 [..]
NYX 0:85b3fd62ea1a 217 Please refer to the ISO 7816-3 specification for more details.
NYX 0:85b3fd62ea1a 218
NYX 0:85b3fd62ea1a 219 [..]
NYX 0:85b3fd62ea1a 220 (@) It is also possible to choose 0.5 stop bit for receiving but it is recommended
NYX 0:85b3fd62ea1a 221 to use 1.5 stop bits for both transmitting and receiving to avoid switching
NYX 0:85b3fd62ea1a 222 between the two configurations.
NYX 0:85b3fd62ea1a 223 [..]
NYX 0:85b3fd62ea1a 224 The HAL_SMARTCARD_Init() function follows the USART SmartCard configuration
NYX 0:85b3fd62ea1a 225 procedure (details for the procedure are available in reference manual (RM0329)).

NYX 0:85b3fd62ea1a 380 ===============================================================================
NYX 0:85b3fd62ea1a 381 [..] This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
NYX 0:85b3fd62ea1a 382
NYX 0:85b3fd62ea1a 383 [..]
NYX 0:85b3fd62ea1a 384 (#) Smartcard is a single wire half duplex communication protocol.
NYX 0:85b3fd62ea1a 385 The Smartcard interface is designed to support asynchronous protocol Smartcards as
NYX 0:85b3fd62ea1a 386 defined in the ISO 7816-3 standard.
NYX 0:85b3fd62ea1a 387 (#) The USART should be configured as:
NYX 0:85b3fd62ea1a 388 (++) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
NYX 0:85b3fd62ea1a 389 (++) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.
NYX 0:85b3fd62ea1a 390
NYX 0:85b3fd62ea1a 391 (#) There are two modes of transfer:
NYX 0:85b3fd62ea1a 392 (++) Blocking mode: The communication is performed in polling mode.
NYX 0:85b3fd62ea1a 393 The HAL status of all data processing is returned by the same function
NYX 0:85b3fd62ea1a 394 after finishing transfer.
NYX 0:85b3fd62ea1a 395 (++) Non Blocking mode: The communication is performed using Interrupts
NYX 0:85b3fd62ea1a 396 or DMA, These APIs return the HAL status.
NYX 0:85b3fd62ea1a 397 The end of the data processing will be indicated through the
NYX 0:85b3fd62ea1a 398 dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
NYX 0:85b3fd62ea1a 399 using DMA mode.
NYX 0:85b3fd62ea1a 400 The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
NYX 0:85b3fd62ea1a 401 will be executed respectively at the end of the Transmit or Receive process
NYX 0:85b3fd62ea1a 402 The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication error is detected
NYX 0:85b3fd62ea1a 403
NYX 0:85b3fd62ea1a 404 (#) Blocking mode APIs are :
NYX 0:85b3fd62ea1a 405 (++) HAL_SMARTCARD_Transmit()
NYX 0:85b3fd62ea1a 406 (++) HAL_SMARTCARD_Receive()
NYX 0:85b3fd62ea1a 407
NYX 0:85b3fd62ea1a 408 (#) Non Blocking mode APIs with Interrupt are :
NYX 0:85b3fd62ea1a 409 (++) HAL_SMARTCARD_Transmit_IT()
NYX 0:85b3fd62ea1a 410 (++) HAL_SMARTCARD_Receive_IT()
NYX 0:85b3fd62ea1a 411 (++) HAL_SMARTCARD_IRQHandler()
NYX 0:85b3fd62ea1a 412
NYX 0:85b3fd62ea1a 413 (#) Non Blocking mode functions with DMA are :
NYX 0:85b3fd62ea1a 414 (++) HAL_SMARTCARD_Transmit_DMA()
NYX 0:85b3fd62ea1a 415 (++) HAL_SMARTCARD_Receive_DMA()
NYX 0:85b3fd62ea1a 416
NYX 0:85b3fd62ea1a 417 (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
NYX 0:85b3fd62ea1a 418 (++) HAL_SMARTCARD_TxCpltCallback()
NYX 0:85b3fd62ea1a 419 (++) HAL_SMARTCARD_RxCpltCallback()
