- * @brief SMARTCARD HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the SmartCard.
- * + Initialization and de-initialization methods
- * + IO operation methods
- * + Peripheral Control methods
- *
- *
- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The SMARTCARD HAL driver can be used as follow:
-
- (#) Declare a SMARTCARD_HandleTypeDef handle structure.
- (#) Associate a USART to the SMARTCARD handle hsc.
- (#) 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 these USART 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.
- (@) The specific USART 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.
- (##) 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, 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 hsc Init structure.
-
- (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
- in the hsc AdvancedInit structure.
-
- (#) Initialize the SMARTCARD associated USART registers by calling
- the HAL_SMARTCARD_Init() API.
-
- (@) HAL_SMARTCARD_Init() API also configure also the low level Hardware GPIO, CLOCK, CORTEX...etc) by
- calling the customized HAL_SMARTCARD_MspInit() API.

- ##### Initialization and Configuration functions #####

- associated to the SmartCard.
- (+) These parameters can be configured:
- (++) Baud Rate
- (++) Parity: parity should be enabled,
- Frame Length is fixed to 8 bits plus parity:
- the USART frame format is given in the following table:
- +---------------------------------------------------------------+
- | M1M0 bits | PCE bit | USART frame |
- |-----------------------|---------------------------------------|
- | 01 | 1 | | SB | 8 bit data | PB | STB | |
- +---------------------------------------------------------------+
- (++) Receiver/transmitter modes
- (++) Synchronous mode (and if enabled, phase, polarity and last bit parameters)
- (++) Prescaler value
- (++) Guard bit time
- (++) NACK enabling or disabling on transmission error
-
- (+) The following advanced features can be configured as well:
- (++) TX and/or RX pin level inversion
- (++) data logical level inversion
- (++) RX and TX pins swap
- (++) RX overrun detection disabling
- (++) DMA disabling on RX error
- (++) MSB first on communication line
- (++) Time out enabling (and if activated, timeout value)
- (++) Block length
- (++) Auto-retry counter
-
- [..]
- The HAL_SMARTCARD_Init() API follow respectively the USART (a)synchronous configuration procedures
- (details for the procedures are available in reference manual).

- ##### IO operation functions #####
- ===============================================================================
- This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
-
- (#) There are two mode 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, These 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 respectivelly 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 API's are :
- (+) HAL_SMARTCARD_Transmit()
- (+) HAL_SMARTCARD_Receive()
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_SMARTCARD_Transmit_IT()
- (+) HAL_SMARTCARD_Receive_IT()
- (+) HAL_SMARTCARD_IRQHandler()
- (+) SMARTCARD_Transmit_IT()
- (+) SMARTCARD_Receive_IT()
-
- (#) No-Blocking mode functions with DMA are :
- (+) HAL_SMARTCARD_Transmit_DMA()
- (+) HAL_SMARTCARD_Receive_DMA()
-
- (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
- (+) HAL_SMARTCARD_TxCpltCallback()
- (+) HAL_SMARTCARD_RxCpltCallback()
