基于ARM7的以太网接口的设计与实现

Design and Realization of Ethernet interface Based on ARM7

以太网接口是以太网中各节点的通信基础,处于TCP/IP协议栈的数据链路层,是信息传递和管理的重要环节。本文提出了一种嵌入式以太网接口的设计与实现,采用STR710微控制器与以太网控制芯片CS8900A进行硬件设计,通过TCP/UDP协议进行通讯,给出了相关硬件连接图及软件的实现,并结合了基于ARM7的电压谐波智能监测及消谐装置的实例研究。

Etbelnet interface is the foundation of communication of each node in internet which is on data link layer （DLL） of TCP/IP protocol stack and is a key link of information transmission and management. The design and principle of the embedded Ethemet interface based on ARM is introduced, hardware design used microprocessor STRT10 connection with CS8900A, and communicated by TCP/UDP protocol, implement of software and hardware connenction are given, with the examples of the research of voltage harmonic intelligent monitoring and elimination device based on ARMT.
