【摘要】 随着嵌入式设备的发展,很多嵌入式设备都具有网口通信功能,通过网口对嵌入式设备进行内部参数设置是一种既方便又简单的方式。设计了一种基于LwIP协议的嵌入式设备Web服务器。利用网页就可以配置嵌入式设备内部参数及程序升级。充分利用STM32平台内部集成以太网模块和LwIP轻型网络协议栈的特点,通过以太网物理层芯片LAN8720和RJ45接口相连,完成了网页和Web服务器之间的数据收发。测试表明,设计的基于LwIP协议栈的嵌入式设备Web服务器是正确和可行的。更多还原

【Abstract】 With the development of embedded devices,many embedded devices have the function of network communication,and it is a convenient and easy way to set the internal parameters of embedded devices through the network port. This paper designs an embedded device Web server based on LwIP protocol. The internal parameters of embedded devices can be configured and updated by using the web page. The Web server make full use of the platform of STM32 internal integration Ethernet modules and the characteristics of LwIP light network protocol stack. Through the Ethernet physical layer chip LAN8720 and RJ45 interface to link together,Web pages and Web server can achieve bidirectional data transmission. The test shows that the embedded device Web server based on the LwIP protocol stack is correct and feasible.更多还原
