##### 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 :

|
|

|
|

|
|

|
|

|
|

This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
|
|
|
|
[..]
|
|
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.
|
|
(++) Non-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 :
|
|
(++) HAL_SMARTCARD_Transmit_DMA()
|
|
(++) HAL_SMARTCARD_Receive_DMA()
|
|
|
|
(+) A set of Transfer Complete Callbacks are provided in non Blocking mode:
|
|
(++) HAL_SMARTCARD_TxCpltCallback()
|
|
(++) HAL_SMARTCARD_RxCpltCallback()
|
|
(++) HAL_SMARTCARD_ErrorCallback()
|
|
|
|
(#) Non-Blocking mode transfers could be aborted using Abort API's :
|
|
(+) HAL_SMARTCARD_Abort()
|
|
(+) HAL_SMARTCARD_AbortTransmit()
|
|
(+) HAL_SMARTCARD_AbortReceive()
|
|
(+) HAL_SMARTCARD_Abort_IT()
|
|
(+) HAL_SMARTCARD_AbortTransmit_IT()
|
|
(+) HAL_SMARTCARD_AbortReceive_IT()
|
|
|
|
(#) For Abort services based on interrupts (HAL_SMARTCARD_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
|
|
(+) HAL_SMARTCARD_AbortCpltCallback()
|
|
(+) HAL_SMARTCARD_AbortTransmitCpltCallback()
|
|
(+) HAL_SMARTCARD_AbortReceiveCpltCallback()
|
|
|
|
(#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
|
|
Errors are handled as follows :
|
|
(+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
|
|
to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
|
|
Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
|
|
and HAL_SMARTCARD_ErrorCallback() user callback is executed. Transfer is kept ongoing on SMARTCARD side.
|
|
If user wants to abort it, Abort services should be called by user.
|
|
(+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
|
|
This concerns Frame Error in Interrupt mode tranmission, Overrun Error in Interrupt mode reception and all errors in DMA mode.
|
|
Error code is set to allow user to identify error type, and HAL_SMARTCARD_ErrorCallback() user callback is executed.
