/** ****************************************************************************** * @file stm32h7xx_hal_fdcan.c * @author MCD Application Team * @version V1.2.0 * @date 29-December-2017 * @brief FDCAN HAL module driver. * This file provides firmware functions to manage the following * functionalities of the Flexible DataRate Controller Area Network * (FDCAN) peripheral: * + Initialization and de-initialization functions * + IO operation functions * + Peripheral Configuration and Control functions * + Peripheral State and Error functions * @verbatim ============================================================================== ##### How to use this driver ##### ============================================================================== [..] (#) Initialize the FDCAN peripheral using HAL_FDCAN_Init function. (#) If needed , configure the reception filters and optional features using the following configuration functions: (++) HAL_FDCAN_ConfigClockCalibration (++) HAL_FDCAN_ConfigFilter (++) HAL_FDCAN_ConfigGlobalFilter (++) HAL_FDCAN_ConfigExtendedIdMask (++) HAL_FDCAN_ConfigRxFifoOverwrite (++) HAL_FDCAN_ConfigFifoWatermark (++) HAL_FDCAN_ConfigRamWatchdog (++) HAL_FDCAN_ConfigTimestampCounter (++) HAL_FDCAN_EnableTimestampCounter (++) HAL_FDCAN_DisableTimestampCounter (++) HAL_FDCAN_ConfigTimeoutCounter (++) HAL_FDCAN_EnableTimeoutCounter (++) HAL_FDCAN_DisableTimeoutCounter (++) HAL_FDCAN_ConfigTxDelayCompensation (++) HAL_FDCAN_EnableTxDelayCompensation (++) HAL_FDCAN_DisableTxDelayCompensation (++) HAL_FDCAN_TT_ConfigOperation (++) HAL_FDCAN_TT_ConfigReferenceMessage (++) HAL_FDCAN_TT_ConfigTrigger (#) Start the FDCAN module using HAL_FDCAN_Start function. At this level the node is active on the bus: it can send and receive messages. (#) The following Tx control functions can only be called when the FDCAN module is started: (++) HAL_FDCAN_AddMessageToTxFifoQ (++) HAL_FDCAN_EnableTxBufferRequest (++) HAL_FDCAN_AbortTxRequest (#) When a message is received into the FDCAN message RAM, it can be retrieved using the HAL_FDCAN_GetRxMessage function. (#) Calling the HAL_FDCAN_Stop function stops the FDCAN module by entering it to initialization mode and re-enabling access to configuration registers through the configuration functions listed here above. (#) All other control functions can be called any time after initialization phase, no matter if the FDCAN module is started or stoped. *** Polling mode operation *** ============================== [..] (#) Reception and transmission states can be monitored via the following functions: (++) HAL_FDCAN_IsRxBufferMessageAvailable (++) HAL_FDCAN_IsTxBufferMessagePending (++) HAL_FDCAN_GetRxFifoFillLevel (++) HAL_FDCAN_GetTxFifoFreeLevel *** Interrupt mode operation *** ================================ [..] (#) There are two interrupt lines: line 0 and 1. By default, all interrupts are assigned to line 0. Interrupt lines can be configured using HAL_FDCAN_ConfigInterruptLines function. (#) Notifications are activated using HAL_FDCAN_ActivateNotification function. Then, the process can be controlled through one of the available user callbacks: HAL_FDCAN_xxxCallback. @endverbatim ****************************************************************************** * @attention * * <h2><center>&copy; COPYRIGHT(c) 2017 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
