摘　　要：设计了一种基于以太网控制器W5100和32bitARM微处理器STM32F105V的嵌入式以太网通信接口。介绍了W5100的工作原理、接口硬件设计及软件设计方案。硬件部分采用SPI总线接口模式实现STM32F105V与W5100连接,软件部分着重对网络控制器的4个独立端口编程,实现以太网数据快速收发功能。本接口设计可直接应用于工业数据采集系统开发。The paper describes a design of embedded Ethernet communication interface based on W5100 and 32-bit ARM processor STM32F105V. The paper presents the work principle of W5100, the hardware and software design of the interface in detail. In the part of hardware, SPI bus interface mode is used to achieve the connection between STM32F105V and W5100. In the part of software, it emphasizes four independent socket of network controller programming to achieve fast Ethernet transceiver functions. The interface design can be directly applied to industrial data acquisition system.
