基于ENC28J60的以太网接口的设计与实现

Design and Implementation of Ethernet Interface Based on ENC28J60

面对各种各样的以太网接口设计,为了寻求一种简单而有效地网络接口,提出了一种基于ENC28J60的接口网络设计。ENC28J60符合IEEE802.3协议,不仅能提供以太网通信的相应功能,而且体积小,可以设计出较小的嵌入式网关。参照传输控制协议/网际协议,通过基于ENC28J60和单片机的网关的硬件设计与软件设计,实现了Internet与单片机的通信。分析表明:基于单片机和ENC28J60的网络接口具有接口简单,开发方便,成本低,十分适用于嵌入式系统,特别是基于嵌入式的智能家居控制系统的应用。

In the face of all kinds of design of Ethernet interface,in order to find a simple and effective network in- terface, it gives a design of network interface based on ENC28J60. ENC28J60 with IEEES02.3 protocol can not only provide the corresponding function of the Ethernet communication, but also has the advantages of small volume, and it can design the embedded gateway smaller. It has software and hardware designations. And Based on ENC28J60, single chip microcomputer and the TCP/IP protocol stack, it realizes the communication between Internet and single chip microcomputer. Analysis shows that, the network interface based on MCU and ENC28J60 is a simple, easy de- velopment,low cost interface, and it is very suitable for embedded systems, especially the application of intelligent home furnishing control system based on embedded system.
