##### 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() | |

[..] | |
(+) Send an amount of data in non-blocking mode using HAL_SMARTCARD_Transmit_IT() | |

##### IO operation functions ##### | |
============================================================================== | |
[..] | |
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. | |
