随着现代网络技术和嵌入式系统的迅速发展,实现数据在网络上传输已是嵌入式系统研究的重要组成部分,对于进行数据的实时操作也具有现实意义。由ARM处理器LPC2468和以太网芯片DM9000A构建系统,做为微机保护系统的通讯端口,重点实现数据的传送过程。简要说明了以太网接口的的硬件设置,讨论了网络接口的软件设计以及基于IPv6的TCP/IP上层协议的实现过程,完成了使用IPv6实现以太网数据的发送接收。
With the rapid development of modern network technology and embedded system, realizing the data transmission on the network has become an important part of embedded system research, which is also of practical significance for real-time operation of data. By ARM processor LPC2468 and Ethernet chip DM9000A build system, as the communication port of the computer protection system, focusing on the realization of the data transfer process. The hardware configuration of the Ethernet interface is briefly described. The software design of the network interface and the implementation of the TCP / IP upper layer protocol based on IPv6 are discussed. The transmission and reception of Ethernet data using IPv6 are completed.
