bogdanm 0:9b334a45a8ff 17 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 18 ==============================================================================
bogdanm 0:9b334a45a8ff 19 [..]
bogdanm 0:9b334a45a8ff 20 The SMARTCARD HAL driver can be used as follows:
bogdanm 0:9b334a45a8ff 21
bogdanm 0:9b334a45a8ff 22 (#) Declare a SMARTCARD_HandleTypeDef handle structure (eg. SMARTCARD_HandleTypeDef hsmartcard).
bogdanm 0:9b334a45a8ff 23 (#) Associate a USART to the SMARTCARD handle hsmartcard.
bogdanm 0:9b334a45a8ff 24 (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
bogdanm 0:9b334a45a8ff 25 (++) Enable the USARTx interface clock.
bogdanm 0:9b334a45a8ff 26 (++) USART pins configuration:
bogdanm 0:9b334a45a8ff 27 (+++) Enable the clock for the USART GPIOs.
bogdanm 0:9b334a45a8ff 28 (+++) Configure the USART pins (TX as alternate function pull-up, RX as alternate function Input).
bogdanm 0:9b334a45a8ff 29 (++) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
bogdanm 0:9b334a45a8ff 30 and HAL_SMARTCARD_Receive_IT() APIs):
bogdanm 0:9b334a45a8ff 31 (++) Configure the USARTx interrupt priority.
bogdanm 0:9b334a45a8ff 32 (++) Enable the NVIC USART IRQ handle.
bogdanm 0:9b334a45a8ff 33 (++) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
bogdanm 0:9b334a45a8ff 34 and HAL_SMARTCARD_Receive_DMA() APIs):
bogdanm 0:9b334a45a8ff 35 (+++) Declare a DMA handle structure for the Tx/Rx channel.
bogdanm 0:9b334a45a8ff 36 (+++) Enable the DMAx interface clock.
bogdanm 0:9b334a45a8ff 37 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
bogdanm 0:9b334a45a8ff 38 (+++) Configure the DMA Tx/Rx channel.
bogdanm 0:9b334a45a8ff 39 (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
bogdanm 0:9b334a45a8ff 40 (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
bogdanm 0:9b334a45a8ff 41
bogdanm 0:9b334a45a8ff 42 (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
bogdanm 0:9b334a45a8ff 43 the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
bogdanm 0:9b334a45a8ff 44 error enabling or disabling in the hsmartcard handle Init structure.
bogdanm 0:9b334a45a8ff 45
bogdanm 0:9b334a45a8ff 46 (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
bogdanm 0:9b334a45a8ff 47 in the hsmartcard handle AdvancedInit structure.
bogdanm 0:9b334a45a8ff 48
bogdanm 0:9b334a45a8ff 49 (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
bogdanm 0:9b334a45a8ff 50 (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
bogdanm 0:9b334a45a8ff 51 by calling the customized HAL_SMARTCARD_MspInit() API.
bogdanm 0:9b334a45a8ff 52 [..]
bogdanm 0:9b334a45a8ff 53 (@) The specific SMARTCARD interrupts (Transmission complete interrupt,
bogdanm 0:9b334a45a8ff 54 RXNE interrupt and Error Interrupts) will be managed using the macros
bogdanm 0:9b334a45a8ff 55 __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.

bogdanm 0:9b334a45a8ff 375 [..]
bogdanm 0:9b334a45a8ff 376 This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
bogdanm 0:9b334a45a8ff 377
bogdanm 0:9b334a45a8ff 378 [..]
bogdanm 0:9b334a45a8ff 379 Smartcard is a single wire half duplex communication protocol.
bogdanm 0:9b334a45a8ff 380 The Smartcard interface is designed to support asynchronous protocol Smartcards as
bogdanm 0:9b334a45a8ff 381 defined in the ISO 7816-3 standard. The USART should be configured as:
bogdanm 0:9b334a45a8ff 382 (+) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
bogdanm 0:9b334a45a8ff 383 (+) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.
bogdanm 0:9b334a45a8ff 384
bogdanm 0:9b334a45a8ff 385 [..]
bogdanm 0:9b334a45a8ff 386 (+) There are two modes of transfer:
bogdanm 0:9b334a45a8ff 387 (++) Blocking mode: The communication is performed in polling mode.
bogdanm 0:9b334a45a8ff 388 The HAL status of all data processing is returned by the same function
bogdanm 0:9b334a45a8ff 389 after finishing transfer.
bogdanm 0:9b334a45a8ff 390 (++) No-Blocking mode: The communication is performed using Interrupts
bogdanm 0:9b334a45a8ff 391 or DMA, the relevant API's return the HAL status.
bogdanm 0:9b334a45a8ff 392 The end of the data processing will be indicated through the
bogdanm 0:9b334a45a8ff 393 dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
bogdanm 0:9b334a45a8ff 394 using DMA mode.
bogdanm 0:9b334a45a8ff 395 (++) The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
bogdanm 0:9b334a45a8ff 396 will be executed respectively at the end of the Transmit or Receive process
bogdanm 0:9b334a45a8ff 397 The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication
bogdanm 0:9b334a45a8ff 398 error is detected.
bogdanm 0:9b334a45a8ff 399
bogdanm 0:9b334a45a8ff 400 (+) Blocking mode APIs are :
bogdanm 0:9b334a45a8ff 401 (++) HAL_SMARTCARD_Transmit()
bogdanm 0:9b334a45a8ff 402 (++) HAL_SMARTCARD_Receive()
bogdanm 0:9b334a45a8ff 403
bogdanm 0:9b334a45a8ff 404 (+) Non Blocking mode APIs with Interrupt are :
bogdanm 0:9b334a45a8ff 405 (++) HAL_SMARTCARD_Transmit_IT()
bogdanm 0:9b334a45a8ff 406 (++) HAL_SMARTCARD_Receive_IT()
bogdanm 0:9b334a45a8ff 407 (++) HAL_SMARTCARD_IRQHandler()
bogdanm 0:9b334a45a8ff 408
bogdanm 0:9b334a45a8ff 409 (+) Non Blocking mode functions with DMA are :
bogdanm 0:9b334a45a8ff 410 (++) HAL_SMARTCARD_Transmit_DMA()
bogdanm 0:9b334a45a8ff 411 (++) HAL_SMARTCARD_Receive_DMA()
bogdanm 0:9b334a45a8ff 412
bogdanm 0:9b334a45a8ff 413 (+) A set of Transfer Complete Callbacks are provided in non Blocking mode:
