+ * + Peripheral Control functions
+ * + Peripheral State and Error functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### 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()

+ 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.
+ (++) No-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 :
