本程序是基于STM32F107芯片，DM9161为以太网PHY芯片的Lwip裸板移植，借助于网络调试助手可以实现客户端与服务端之间的通信。其以STM32为服务端，电脑为客户端，STM32默认IP为192.168.0.30，端口为23，调试的时候若电脑开有无线网记得把无线网给关掉，不然调试助手连接不上客户端，IP地址可根据实际需要进行修改，一定要记得使stm32客户端的IP与电脑IP处于同一网段，只有在同一网段才能保证两者之间的通信，代码仅供参考学习，若型号不一样可参考修改进行移植(This program is based on STM32F107 chip, DM9161 is the Lwip bare board of Ethernet PHY chip, and the communication between the client and the server can be realized with the help of the network debug assistant. It takes STM32 as the server, the computer as the client, the STM32 default IP 192.168.0.30, the port is 23, and if the computer has a wireless network to turn off the wireless network when debugging, the debug assistant is not connected to the client, and the IP address can be modified according to the actual needs. It is necessary to remember the IP of the STM32 client and the computer IP. In the same network segment, only the same network segment can guarantee the communication between the two. The code is for reference only. If the model is different, it can be modified by reference.)
