AUTOSAR(汽车开放系统架构)是一种标准化的汽车软件架构,旨在实现汽车电子系统的模块化、可重用和可扩展。CANIf(Controller Area Network Interface)是AUTOSAR中的一个模块,用于与CAN总线进行通信。本文将介绍CANIf规范的时序图,并提供相应的源代码示例。
CANIf的时序图描述了CANIf模块与其他AUTOSAR模块之间的交互过程。以下是一个简化的CANIf时序图示例:
@startuml
participant Application
participant CANIf
participant CAN Driver
participant CAN Controller
Application -> CANIf: CanIf_Transmit(PDU)
activate CANIf
CANIf -> CAN Driver: CanIf_Transmit(PDU)
activate CAN Driver
CAN Driver -> CAN Controller: CanDrv_Write(HWObject, PDU)
activate CAN Controller
CAN Controller -> CAN Driver: CanIf_ControllerBusOff(ControllerId)
activate CAN Driver
CAN Driver --> CANIf: E_NOT_OK
deactivate CAN Driver
CANIf --> Application: E_NOT_OK
deactivate CANIf
