摘要
嵌入式系统与以太网结合应用于工业控制领域已得到工业界的广泛认同 ,应用前景是非常广阔的。而网络的关键在于数据通信 ,工业控制网络的特点就更是要求在各个嵌入式系统之间能有准确而快速的通信 ,以太控制网通信的嵌入式实现是很好的解决方案。针对以太网底层的通信 ,文章分析了NE2 0 0 0兼容网卡的硬件结构 ,在此基础上 ,对网卡进行了初始化 ,并按IEEE80 2 .
The combination of Ethernet and embedded system and its application in industry control area are widely approbated with a broad prospect. The key of network is data communication. Due to these qualities satisfy the request of the communication between all kinds of embedded system in industry control networks, the realizing of embedded system based on Ethernet communication can be fit for this requirement. The paper describes the basement protocol of Ethernet communication and the hardware structure of NE2000 compatible. What's more, the paper explicates the chips and initialization of NIC. Finally, the realizing of the data communication of NIC with Borland C program based on the IEEE802.3 Standard is described in this paper.
