基于FPGA的SPI串行接口实时以太网实现

摘要

Industrial Ethernet which belongs to a new on-site control bus,from the network point of view,is in constant improvement and development.The Ethernet interconnection communication system based on the independent Ethernet control er ENC28J60 interface is able to realize the interconnection of embedded control systems with Ethernet and can be applied to transfer the real-time and reliable data,including the principle of the new real-time Ethernet communication,hardware and software design of serial interface SPI,selection and parameter setting of the TCP/IP protocol,TCP/IP communications test.%　　工业以太网，从控制网络的角度来看，属于一种新型的现场控制总线，正处于不断完善和发展中。基于ENC28J60芯片的独立以太网控制器接口通信系统，不仅能实现嵌入式控制系统与以太网的互联，而且能够实时可靠地传输数据，其中包括新型实时以太网通信的原理、串行接口SPI的软硬件设计、TCP/IP协议的选择及参数设置、TCP/IP通信测试。
