基于DM9000A的存储装置的设计

网络的开放性和全球化,促进了人类知识的共享和经济的全球化。以太网技术以其灵活方便的连接方式、良好的开放性、高效、低廉等优点,已经广泛地应用于各种计算机网络,并且还在不断的发展。目前,网络技术在电子产品中的应用越来越广,更多的设备需要提供网络接口,以方便与外部互联通讯。本文介绍了一种利用单片机直接控制以太网控制芯片DM9000A实现以太网接口的方法。文中阐述了DM9000A的工作原理,系统硬件连接方法,软件实现和数据收发方法。该装置通过双绞线与计算机相连,可以实现远距离、快速的数据传输及存储。

Design of storing device based on DM9000A

Network of openness and globalization is promoting human knowledge sharing and economic globalization .Ethernet technology has been used widely to computer network .This is due to the advantage of flexible connections,good openness,high-efficiency and low cost.At present,more and more device need this Network Interface to get connected with others.This paper designs a Ethernet Interface based on a Ethernet controller DM9000A that is controlling directly by MCU.And this paper describes working principle of DM9000A,hardware connection,software and method of data transmission.The device can be connected with computer with UTP.Data can be transmited faster and in long distance.
