****************************************************************************** - * @file stm32f4xx_hal_irda.c - * @author MCD Application Team - * @version V1.4.0 - * @date 14-August-2015 - * @brief IRDA HAL module driver. - * This file provides firmware functions to manage the following - * functionalities of the IrDA SIR ENDEC block (IrDA): - * + Initialization and de-initialization methods - * + IO operation methods - * + Peripheral Control methods - * - @verbatim - ============================================================================== - ##### How to use this driver ##### - ============================================================================== - [..] - The IRDA HAL driver can be used as follows: - - (#) Declare a IRDA_HandleTypeDef handle structure. - (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API: - (##) Enable the USARTx interface clock. - (##) IRDA pins configuration: - (+++) Enable the clock for the IRDA GPIOs. - (+++) Configure these IRDA pins as alternate function pull-up. - (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT() - and HAL_IRDA_Receive_IT() APIs): - (+++) Configure the USARTx interrupt priority. - (+++) Enable the NVIC USART IRQ handle. - (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA() - and HAL_IRDA_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 IRDA 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, Parity, IrDA Mode, Prescaler - and Mode(Receiver/Transmitter) in the hirda Init structure. - - (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API: - (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc) - by calling the customized HAL_IRDA_MspInit() API. - -@@- The specific IRDA interrupts (Transmission complete interrupt, - RXNE interrupt and Error Interrupts) will be managed using the macros - __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_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_IRDA_Transmit() - (+) Receive an amount of data in blocking mode using HAL_IRDA_Receive() - - *** Interrupt mode IO operation *** - =================================== - [..] - (+) Send an amount of data in non blocking mode using HAL_IRDA_Transmit_IT() - (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can - add his own code by customization of function pointer HAL_IRDA_TxCpltCallback - (+) Receive an amount of data in non blocking mode using HAL_IRDA_Receive_IT() - (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can - add his own code by customization of function pointer HAL_IRDA_RxCpltCallback - (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can - add his own code by customization of function pointer HAL_IRDA_ErrorCallback - - *** DMA mode IO operation *** - ============================= - [..] - (+) Send an amount of data in non blocking mode (DMA) using HAL_IRDA_Transmit_DMA() - (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can - add his own code by customization of function pointer HAL_IRDA_TxCpltCallback - (+) Receive an amount of data in non blocking mode (DMA) using HAL_IRDA_Receive_DMA() - (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can - add his own code by customization of function pointer HAL_IRDA_RxCpltCallback - (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can - add his own code by customization of function pointer HAL_IRDA_ErrorCallback - - *** IRDA HAL driver macros list *** - =================================== - [..] - Below the list of most used macros in IRDA HAL driver. - - (+) __HAL_IRDA_ENABLE: Enable the IRDA peripheral - (+) __HAL_IRDA_DISABLE: Disable the IRDA peripheral - (+) __HAL_IRDA_GET_FLAG : Checks whether the specified IRDA flag is set or not - (+) __HAL_IRDA_CLEAR_FLAG : Clears the specified IRDA pending flag - (+) __HAL_IRDA_ENABLE_IT: Enables the specified IRDA interrupt - (+) __HAL_IRDA_DISABLE_IT: Disables the specified IRDA interrupt - - (@) You can refer to the IRDA HAL driver header file for more useful macros - - @endverbatim - ****************************************************************************** -
