9-51单片机ESP8266学习-AT指令(测试TCP服务器--51单片机程序配置8266,C#TCP客户端发信息给单片机控制小灯的亮灭)...-白红宇

自己都是现做现写,如果想知道最终实现的功能,请看最后

先把源码和资料链接放到这里

链接：密码：j1sz

先说一下哈,不要嫌界面不好看,自己是为了程序尽量的简单,可以通过调整颜色或者通过重绘来使使界面好看,,,,,,,,咱先学会走.....

因为咱们会用到图片所以先把图片资源加载上来,为了

调整的好看一点

现在设置,切换图片

其实呢导入图片应该先建一个资源文件更合理,后期再说

现在是让按钮状态改变了

也修改一下灯的

private void pictureBox2_Click(object sender, EventArgs e)        {            if (LedFlage == false)            {                LedFlage = true;                pictureBox2.BackgroundImage = Properties.Resources.switchon;                pictureBox3.BackgroundImage = Properties.Resources.ledon;            }            else            {                LedFlage = false;                pictureBox2.BackgroundImage = Properties.Resources.switchoff;                pictureBox3.BackgroundImage = Properties.Resources.ledoff;            }        }

现在做连接服务器

先说一下很多初学者会遇到的问题

这种情况是你添加了控件的事件函数,然后你又删除了,,,因为我也是经常删.................

我刚才在考虑要不要用委托和回调.....后来想了想这篇就不用了,

大家记得自己试一下这个(反正给大家说了,下次自己肯定用委托和回调写,记住不要偷懒,如果你偷懒了,后期的文章你就会无从下手,因为你连基础的都不知道)

因为和android 一样只有主线程才允许操作控件,咱们就

现在做连接服务器和断开连接

先在电脑上测试

先给现在的程序

断开

忘了加一个功能,,,判断服务器是不是断开了

现在用调试助手试一下

好了咱现在用8266试一试

C#的源码

好了.....但是刚才我在软件连接的时候复位了一下芯片发现软件没有检测出来断开..现在如果服务器主动断开

可以检测的到,异常好像不可以,后期再看看....今天太晚了写的匆忙,不知道软件还有没有其它的Bug,慢慢的去发现吧...

突然有想起来单片机程序有个BUG

好了,感觉压力还很大...还有好多好多每写的.....................
