摘要
文中介绍一种基于高性能处理器STM32的嵌入式串口设备联网技术的系统设计,该系统充分利用UCOS-II实时操作系统和Lw IP轻量型网络协议栈的特点,采用DM9161快速以太网PHY和STM32微处理器等组成,通过以太网实现上位机客户端到串口的数据信息的双向传输,完成串口数据的网络通信。最后对系统进行了测试,结果表明基于UCOS-II和Lw IP的串口设备联网系统设计是正确和高效的。
This article introduces a kind of serial port equipment networking technology of system design based on high- performance processor STM32. The system makes full use of UCOS II real-time operating system and LwlP lightweight characteristics of the network protocol stack, using DMg161 fast Ethernet PHY and STM32 microprocessor, etc. Through Ethernet to realize the data of the serial port of PC client to the two-way transmission of information, we can complete the data of network communication. Finally, the system was tested, the results show that the system based on UCOS-II and LwlP is correct and efficient.
