(+++) 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() -

- ##### 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 @ref HAL_SMARTCARD_RegisterCallback() to register a user callback. - Function @ref 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 @ref HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default - weak (surcharged) function. - @ref 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 @ref HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET - all callbacks are set to the corresponding weak (surcharged) functions: - examples @ref HAL_SMARTCARD_TxCpltCallback(), @ref HAL_SMARTCARD_RxCpltCallback(). - Exception done for MspInit and MspDeInit functions that are respectively - reset to the legacy weak (surcharged) functions in the @ref HAL_SMARTCARD_Init() - and @ref HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand). - If not, MspInit or MspDeInit are not null, the @ref HAL_SMARTCARD_Init() and @ref 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 @ref HAL_SMARTCARD_RegisterCallback() before calling @ref HAL_SMARTCARD_DeInit() - or @ref 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. - - - @endverbatim - ****************************************************************************** -

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. - -@endverbatim - * @{ - */ - -/** - * @brief Send an amount of data in blocking mode. - * @param hsmartcard Pointer to a SMARTCARD_HandleTypeDef structure that contains - * the configuration information for the specified SMARTCARD module. - * @param pData pointer to data buffer. - * @param Size amount of data to be sent. - * @param Timeout Timeout duration. - * @retval HAL status - */ -HAL_StatusTypeDef HAL_SMARTCARD_Transmit(SMARTCARD_HandleTypeDef *hsmartcard, uint8_t *pData, uint16_t Size, - uint32_t Timeout) -{ - uint32_t tickstart;
