bogdanm 0:9b334a45a8ff 16 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 17 ==============================================================================
bogdanm 0:9b334a45a8ff 18 [..]
bogdanm 0:9b334a45a8ff 19 The SMARTCARD HAL driver can be used as follows:
bogdanm 0:9b334a45a8ff 20
bogdanm 0:9b334a45a8ff 21 (#) Declare a SMARTCARD_HandleTypeDef handle structure.
bogdanm 0:9b334a45a8ff 22 (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
bogdanm 0:9b334a45a8ff 23 (##) Enable the USARTx interface clock.
bogdanm 0:9b334a45a8ff 24 (##) SMARTCARD pins configuration:
bogdanm 0:9b334a45a8ff 25 (+++) Enable the clock for the SMARTCARD GPIOs.
bogdanm 0:9b334a45a8ff 26 (+++) Configure these SMARTCARD pins as alternate function pull-up.
bogdanm 0:9b334a45a8ff 27 (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
bogdanm 0:9b334a45a8ff 28 and HAL_SMARTCARD_Receive_IT() APIs):
bogdanm 0:9b334a45a8ff 29 (+++) Configure the USARTx interrupt priority.
bogdanm 0:9b334a45a8ff 30 (+++) Enable the NVIC USART IRQ handle.
bogdanm 0:9b334a45a8ff 31 (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
bogdanm 0:9b334a45a8ff 32 and HAL_SMARTCARD_Receive_DMA() APIs):
bogdanm 0:9b334a45a8ff 33 (+++) Declare a DMA handle structure for the Tx/Rx stream.
bogdanm 0:9b334a45a8ff 34 (+++) Enable the DMAx interface clock.
bogdanm 0:9b334a45a8ff 35 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
bogdanm 0:9b334a45a8ff 36 (+++) Configure the DMA Tx/Rx Stream.
bogdanm 0:9b334a45a8ff 37 (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
bogdanm 0:9b334a45a8ff 38 (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
bogdanm 0:9b334a45a8ff 39
bogdanm 0:9b334a45a8ff 40 (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware
bogdanm 0:9b334a45a8ff 41 flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure.
bogdanm 0:9b334a45a8ff 42
bogdanm 0:9b334a45a8ff 43 (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
bogdanm 0:9b334a45a8ff 44 (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc)
bogdanm 0:9b334a45a8ff 45 by calling the customized HAL_SMARTCARD_MspInit() API.
bogdanm 0:9b334a45a8ff 46 [..]
bogdanm 0:9b334a45a8ff 47 (@) The specific SMARTCARD interrupts (Transmission complete interrupt,
bogdanm 0:9b334a45a8ff 48 RXNE interrupt and Error Interrupts) will be managed using the macros
bogdanm 0:9b334a45a8ff 49 __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
bogdanm 0:9b334a45a8ff 50

bogdanm 0:9b334a45a8ff 180 [..]
bogdanm 0:9b334a45a8ff 181 This subsection provides a set of functions allowing to initialize the USART
bogdanm 0:9b334a45a8ff 182 in Smartcard mode.
bogdanm 0:9b334a45a8ff 183 [..]
bogdanm 0:9b334a45a8ff 184 The Smartcard interface is designed to support asynchronous protocol Smartcards as
bogdanm 0:9b334a45a8ff 185 defined in the ISO 7816-3 standard.
bogdanm 0:9b334a45a8ff 186 [..]
bogdanm 0:9b334a45a8ff 187 The USART can provide a clock to the smartcard through the SCLK output.
bogdanm 0:9b334a45a8ff 188 In smartcard mode, SCLK is not associated to the communication but is simply derived
bogdanm 0:9b334a45a8ff 189 from the internal peripheral input clock through a 5-bit prescaler.
bogdanm 0:9b334a45a8ff 190 [..]
bogdanm 0:9b334a45a8ff 191 (+) For the Smartcard mode only these parameters can be configured:
bogdanm 0:9b334a45a8ff 192 (++) Baud Rate
bogdanm 0:9b334a45a8ff 193 (++) Word Length => Should be 9 bits (8 bits + parity)
bogdanm 0:9b334a45a8ff 194 (++) Stop Bit
bogdanm 0:9b334a45a8ff 195 (++) Parity: => Should be enabled
bogdanm 0:9b334a45a8ff 196 +-------------------------------------------------------------+
bogdanm 0:9b334a45a8ff 197 | M bit | PCE bit | SMARTCARD frame |
bogdanm 0:9b334a45a8ff 198 |---------------------|---------------------------------------|
bogdanm 0:9b334a45a8ff 199 | 1 | 1 | | SB | 8 bit data | PB | STB | |
bogdanm 0:9b334a45a8ff 200 +-------------------------------------------------------------+
bogdanm 0:9b334a45a8ff 201 (++) USART polarity
bogdanm 0:9b334a45a8ff 202 (++) USART phase
bogdanm 0:9b334a45a8ff 203 (++) USART LastBit
bogdanm 0:9b334a45a8ff 204 (++) Receiver/transmitter modes
bogdanm 0:9b334a45a8ff 205 (++) Prescaler
bogdanm 0:9b334a45a8ff 206 (++) GuardTime
bogdanm 0:9b334a45a8ff 207 (++) NACKState: The Smartcard NACK state
bogdanm 0:9b334a45a8ff 208
bogdanm 0:9b334a45a8ff 209 (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
bogdanm 0:9b334a45a8ff 210 (++) Word Length = 9 Bits
bogdanm 0:9b334a45a8ff 211 (++) 1.5 Stop Bit
bogdanm 0:9b334a45a8ff 212 (++) Even parity
bogdanm 0:9b334a45a8ff 213 (++) BaudRate = 12096 baud
bogdanm 0:9b334a45a8ff 214 (++) Tx and Rx enabled
bogdanm 0:9b334a45a8ff 215 [..]
bogdanm 0:9b334a45a8ff 216 Please refer to the ISO 7816-3 specification for more details.
bogdanm 0:9b334a45a8ff 217
bogdanm 0:9b334a45a8ff 218 -@- It is also possible to choose 0.5 stop bit for receiving but it is recommended
bogdanm 0:9b334a45a8ff 219 to use 1.5 stop bits for both transmitting and receiving to avoid switching
bogdanm 0:9b334a45a8ff 220 between the two configurations.
bogdanm 0:9b334a45a8ff 221 [..]
bogdanm 0:9b334a45a8ff 222 The HAL_SMARTCARD_Init() function follows the USART SmartCard configuration
bogdanm 0:9b334a45a8ff 223 procedure (details for the procedure are available in reference manual (RM0329)).

bogdanm 0:9b334a45a8ff 366 This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
bogdanm 0:9b334a45a8ff 367 [..]
bogdanm 0:9b334a45a8ff 368 Smartcard is a single wire half duplex communication protocol.
bogdanm 0:9b334a45a8ff 369 The Smartcard interface is designed to support asynchronous protocol Smartcards as
bogdanm 0:9b334a45a8ff 370 defined in the ISO 7816-3 standard. The USART should be configured as:
bogdanm 0:9b334a45a8ff 371 (+) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
bogdanm 0:9b334a45a8ff 372 (+) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.
bogdanm 0:9b334a45a8ff 373
bogdanm 0:9b334a45a8ff 374 (#) There are two modes of transfer:
bogdanm 0:9b334a45a8ff 375 (++) Blocking mode: The communication is performed in polling mode.
bogdanm 0:9b334a45a8ff 376 The HAL status of all data processing is returned by the same function
bogdanm 0:9b334a45a8ff 377 after finishing transfer.
bogdanm 0:9b334a45a8ff 378 (++) Non Blocking mode: The communication is performed using Interrupts
bogdanm 0:9b334a45a8ff 379 or DMA, These APIs return the HAL status.
bogdanm 0:9b334a45a8ff 380 The end of the data processing will be indicated through the
bogdanm 0:9b334a45a8ff 381 dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
bogdanm 0:9b334a45a8ff 382 using DMA mode.
bogdanm 0:9b334a45a8ff 383 The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
bogdanm 0:9b334a45a8ff 384 will be executed respectively at the end of the Transmit or Receive process
bogdanm 0:9b334a45a8ff 385 The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication error is detected
bogdanm 0:9b334a45a8ff 386
bogdanm 0:9b334a45a8ff 387 (#) Blocking mode APIs are :
bogdanm 0:9b334a45a8ff 388 (++) HAL_SMARTCARD_Transmit()
bogdanm 0:9b334a45a8ff 389 (++) HAL_SMARTCARD_Receive()
bogdanm 0:9b334a45a8ff 390
bogdanm 0:9b334a45a8ff 391 (#) Non Blocking mode APIs with Interrupt are :
bogdanm 0:9b334a45a8ff 392 (++) HAL_SMARTCARD_Transmit_IT()
bogdanm 0:9b334a45a8ff 393 (++) HAL_SMARTCARD_Receive_IT()
bogdanm 0:9b334a45a8ff 394 (++) HAL_SMARTCARD_IRQHandler()
bogdanm 0:9b334a45a8ff 395
bogdanm 0:9b334a45a8ff 396 (#) Non Blocking mode functions with DMA are :
bogdanm 0:9b334a45a8ff 397 (++) HAL_SMARTCARD_Transmit_DMA()
bogdanm 0:9b334a45a8ff 398 (++) HAL_SMARTCARD_Receive_DMA()
