****************************************************************************** - * @file stm32f4xx_hal_smartcard.c - * @author MCD Application Team - * @version V1.4.0 - * @date 14-August-2015 - * @brief SMARTCARD HAL module driver. - * This file provides firmware functions to manage the following - * functionalities of the SMARTCARD peripheral: - * + Initialization and de-initialization functions - * + IO operation functions - * + Peripheral State and Errors functions - * - @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 USARTx interface clock. - (##) SMARTCARD pins configuration: - (+++) Enable the clock for the SMARTCARD GPIOs. - (+++) Configure these 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. - - (#) 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_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 -
