摘要
随着Internet的发展和应用,嵌入式系统在网络方面的应用技术也逐渐成熟。针对目前大量使用8位微控制器的嵌入式系统,采用ATMEL公司的高性能单片机ATmega64和10 Mb/s以太网控制芯片RTL8019AS,设计了低成本的嵌入式以太网接口,详细介绍了硬件电路的连接以及嵌入式TCP/IP的实现,远端用户可以通过HTTP协议来访问存储在嵌入式系统上的网页,使嵌入式系统具备网络连接功能。
The application technology in network of embedded system is becoming mature with the development and application of Internet. In view of large - scale use of 8 - bit microcontroller embedded systems at present,a low cost embedded Ethernet interface is realized by adopting high performance microcontroller Atmega64 of the ATMEL Corporation and 10M Ethernet-controller RTL8019AS, hardware circuit＇s connection and embedded TCP/IP realization are introduced in detail. Remote users can access the web pages stored in embedded system by a browser,which offered network function to embedded system.
