摘　　要：文中介绍一种基于高性能、低成本ARM处理器--STM32的嵌入式设备以太网通信技术的系统设计,系统充分利用μC/OS-II实时操作系统和Lw IP轻量型网络协议栈的特点,通过以太网控制器DP83848和RJ45接口连接网络,实现上位机和客户端的双向数据传输。测试结果表明,基于μC/OS-II和Lw IP的嵌入式设备联网系统设计是正确和可靠的。This paper introduces a kind of embedded devices networking technology of system design based on high-performance and low-cost ARM processor STM32. The system makes full use of the real- time operating system μC/OS-Ⅱ and light weight internet protocol stack. Through the ethernet controller DP83848 and R J45 interface to connect to the internet. Realize the PC and client double data transmission. Test results show that the system design of embedded devices connected to network based on the μC/OS-Ⅱ and light weight internet protocol is correct and reliable.
