【STM32F723 Discovery Kit】tcp server和tcp client测试

TL-LED 发表于 2023-11-4 11:23

这篇来测试下，在w5500模块上实现tcp server和tcp client测试。在上篇<a href="https://bbs.eeworld.com.cn/thread-1262011-1-1.html" target="_blank">https://bbs.eeworld.com.cn/thread-1262011-1-1.html</a>的基础上，添加tcp 代码。

二、运行结果

 

2.1、tcp server 测试

串口输出



 

网络调试助手



开发板回复网络调试助手发送的内容

 

2.2、tcp client 测试

先打开网络调试助手，创建服务器，然后给开发板上电，建立网络连接

建立连接后，网络调试助手发送消息后，收到开发板的回复，同时串口输出收到的消息。



 

以上是tcp server 和tcp client测试的内容。
