| @verbatim |
| ============================================================================== |
| ##### How to use this driver ##### |
| ============================================================================== |
| [..] |
| The SMARTCARD HAL driver can be used as follows: |
| |
| (#) Declare a SMARTCARD_HandleTypeDef handle structure. |
| (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API: |
| (##) Enable the interface clock of the USARTx associated to the SMARTCARD. |
| (##) SMARTCARD pins configuration: |
| (+++) Enable the clock for the SMARTCARD GPIOs. |
| (+++) Configure SMARTCARD 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. |
| (##) 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. |
| (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle |
| (used for last byte sending completion detection in DMA non circular mode) |
| |
| (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware |
| flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure. |
| |
| (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API: |
| (++) These APIs configure 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() |
| (+) 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 (DMA) using HAL_SMARTCARD_Receive_DMA() |
| (+) 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 |
| |
| *** SMARTCARD HAL driver macros list *** |
| ======================================== |
| [..] |
| Below the list of most used macros in SMARTCARD HAL driver. |
| |
| (+) __HAL_SMARTCARD_ENABLE: Enable the SMARTCARD peripheral |
| (+) __HAL_SMARTCARD_DISABLE: Disable the SMARTCARD peripheral |
| (+) __HAL_SMARTCARD_GET_FLAG : Check whether the specified SMARTCARD flag is set or not |
| (+) __HAL_SMARTCARD_CLEAR_FLAG : Clear the specified SMARTCARD pending flag |
| (+) __HAL_SMARTCARD_ENABLE_IT: Enable the specified SMARTCARD interrupt |
| (+) __HAL_SMARTCARD_DISABLE_IT: Disable the specified SMARTCARD interrupt |
| |
| [..] |
| (@) You can refer to the SMARTCARD HAL driver header file for more useful macros |
| |
| ##### Callback registration ##### |
| ================================== |
| |
| [..] |
| The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS when set to 1 |
| allows the user to configure dynamically the driver callbacks. |
| |
| [..] |
| Use Function HAL_SMARTCARD_RegisterCallback() to register a user callback. |
| Function HAL_SMARTCARD_RegisterCallback() allows to register following callbacks: |
| (+) TxCpltCallback : Tx Complete Callback. |
| (+) RxCpltCallback : Rx Complete Callback. |
| (+) ErrorCallback : Error Callback. |
| (+) AbortCpltCallback : Abort Complete Callback. |
| (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. |
| (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. |
| (+) MspInitCallback : SMARTCARD MspInit. |
| (+) MspDeInitCallback : SMARTCARD MspDeInit. |
| This function takes as parameters the HAL peripheral handle, the Callback ID |
| and a pointer to the user callback function. |
| |
| [..] |
| Use function HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default |
| weak (surcharged) function. |
| HAL_SMARTCARD_UnRegisterCallback() takes as parameters the HAL peripheral handle, |
| and the Callback ID. |
| This function allows to reset following callbacks: |
| (+) TxCpltCallback : Tx Complete Callback. |
| (+) RxCpltCallback : Rx Complete Callback. |
| (+) ErrorCallback : Error Callback. |
| (+) AbortCpltCallback : Abort Complete Callback. |
| (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. |
| (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. |
| (+) MspInitCallback : SMARTCARD MspInit. |
| (+) MspDeInitCallback : SMARTCARD MspDeInit. |
| |
| [..] |
| By default, after the HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET |
| all callbacks are set to the corresponding weak (surcharged) functions: |
| examples HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback(). |
| Exception done for MspInit and MspDeInit functions that are respectively |
| reset to the legacy weak (surcharged) functions in the HAL_SMARTCARD_Init() |
| and HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand). |
| If not, MspInit or MspDeInit are not null, the HAL_SMARTCARD_Init() and HAL_SMARTCARD_DeInit() |
| keep and use the user MspInit/MspDeInit callbacks (registered beforehand). |
| |
| [..] |
| Callbacks can be registered/unregistered in HAL_SMARTCARD_STATE_READY state only. |
| Exception done MspInit/MspDeInit that can be registered/unregistered |
| in HAL_SMARTCARD_STATE_READY or HAL_SMARTCARD_STATE_RESET state, thus registered (user) |
| MspInit/DeInit callbacks can be used during the Init/DeInit. |
| In that case first register the MspInit/MspDeInit user callbacks |
| using HAL_SMARTCARD_RegisterCallback() before calling HAL_SMARTCARD_DeInit() |
| or HAL_SMARTCARD_Init() function. |
| |
| [..] |
| When The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS is set to 0 or |
| not defined, the callback registration feature is not available |
| and weak (surcharged) callbacks are used. |

| ##### Initialization and Configuration functions ##### |
| ============================================================================== |
| [..] |
| This subsection provides a set of functions allowing to initialize the USART |
| in Smartcard mode. |
| [..] |
| The Smartcard interface is designed to support asynchronous protocol Smartcards as |
| defined in the ISO 7816-3 standard. |
| [..] |
| The USART can provide a clock to the smartcard through the SCLK output. |
| In smartcard mode, SCLK is not associated to the communication but is simply derived |
| from the internal peripheral input clock through a 5-bit prescaler. |
| [..] |
| (+) For the Smartcard mode only these parameters can be configured: |
| (++) Baud Rate |
| (++) Word Length => Should be 9 bits (8 bits + parity) |
| (++) Stop Bit |
| (++) Parity: => Should be enabled |
| (++) USART polarity |
| (++) USART phase |
| (++) USART LastBit |
| (++) Receiver/transmitter modes |
| (++) Prescaler |
| (++) GuardTime |
| (++) NACKState: The Smartcard NACK state |
| |
| (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card: |
| (++) Word Length = 9 Bits |
| (++) 1.5 Stop Bit |
| (++) Even parity |
| (++) BaudRate = 12096 baud |
| (++) Tx and Rx enabled |
| [..] |
| Please refer to the ISO 7816-3 specification for more details. |
| |
| [..] |
| (@) It is also possible to choose 0.5 stop bit for receiving but it is recommended |
| to use 1.5 stop bits for both transmitting and receiving to avoid switching |
| between the two configurations. |
| [..] |
| The HAL_SMARTCARD_Init() function follows the USART SmartCard configuration |
| procedures (details for the procedures are available in reference manual |
| (RM0430 for STM32F4X3xx MCUs and RM0402 for STM32F412xx MCUs |
| RM0383 for STM32F411xC/E MCUs and RM0401 for STM32F410xx MCUs |
| RM0090 for STM32F4X5xx/STM32F4X7xx/STM32F429xx/STM32F439xx MCUs |
| RM0390 for STM32F446xx MCUs and RM0386 for STM32F469xx/STM32F479xx MCUs)). |
| |
| @endverbatim |
| |
| The SMARTCARD frame format is given in the following table: |
| +-------------------------------------------------------------+ |
| | M bit | PCE bit | SMARTCARD frame | |
| |---------------------|---------------------------------------| |
| | 1 | 1 | | SB | 8 bit data | PB | STB | | |

| =============================================================================== |
| ##### 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, These APIs 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 transmission, 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. |
