7-51單片機ESP8266學習-AT指令(8266TCP服務器,編寫自己的C#TCP客戶端發信息給單片機控制小燈的亮滅)

 http://www.cnblogs.com/yangfengwu/p/8780182.html

自己都是現做現寫,如果想知道最終實現的功能,請看最后

 

先把源碼和資料鏈接放到這里

鏈接： https://pan.baidu.com/s/1jpHZjW_7pQKNfN9G4B6ZjA     密碼：nhn3 

 

 

先說一下哈,不要嫌界面不好看,自己是為了程序盡量的簡單,可以通過調整顏色或者通過重繪來使使界面好看,,,,,,,,咱先學會走.....

 

 

 

因為咱們會用到圖片所以先把圖片資源加載上來,為了

 

 

 

 

 

 

 

 

 

 

 調整的好看一點

 

 

 

現在設置,切換圖片

 

 

其實呢導入圖片應該先建一個資源文件更合理,后期再說

現在是讓按鈕狀態改變了

  

 

也修改一下燈的

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;
            }
        }

 

 現在做連接服務器

先說一下很多初學者會遇到的問題

 

這種情況是你添加了控件的事件函數,然后你又刪除了,,,因為我也是經常刪.................

 

我剛才在考慮要不要用委托和回調.....后來想了想這篇就不用了,

大家記得自己試一下這個(反正給大家說了,下次自己肯定用委托和回調寫,記住不要偷懶,如果你偷懶了,后期的文章你就會無從下手,因為你連基礎的都不知道)

http://www.cnblogs.com/yangfengwu/p/5761841.html

因為和android 一樣只有主線程才允許操作控件,咱們就

 

現在做連接服務器和斷開連接

先在電腦上測試

現在用調試助手試一下

 

 

好了咱現在用8266試一試 

 

 

 

 

 

 C#的源碼

 

 

 

 

好了.....但是剛才我在軟件連接的時候復位了一下芯片發現軟件沒有檢測出來斷開..現在如果服務器主動斷開

可以檢測的到,異常好像不可以,后期再看看....今天太晚了寫的匆忙,不知道軟件還有沒有其它的Bug,慢慢的去發現吧...

突然有想起來單片機程序有個BUG
