摘要
介绍智能型监控卡的设计方案,该监控卡用于CAN总线与计算机之间通信,集诊断、处理、存储、通讯功能于一身,既能通过计算机的EPP端口与计算机通讯,由计算机完成对总线上其它CAN节点的网络管理、监控、通信等功能。同时介绍增强型计算机并行端口的管脚定义及寄存器地址,给出该智能型监控卡的主程序流程图。
In this study,an intelligent interface for management and control between CAN field bus and computer was designed.The advantage of this design is that functions of diagnosis,disposal,storage and communication can be simultaneously completed.The interface not only can communicates with computer using EPP port but also can works independently through the computer control other CAN nodes to perform,by itself,the functions of network management and communication etc.The definition of EPP pins and register addresses are described in this design.The main procedure flow chart was included in the description.
