基于Python的简单读卡上位机界面

使用到的模块，pyserial pyqt5 pymysql

（我先是实现在命令行下通过串口进行对板子硬件的控制，比如Led ，beep等，在实现检测卡（是否选卡成功），连接卡（验证哪一个扇区），读卡，写卡）（对于m1卡的读写地址，在连接卡时就指定了，在没有halt操作或移开卡的操作之前，是没法更改扇区的)

后续慢慢加。。

先传几张，调试好的图（第三张图的读区显示少了一个s是因为在写的时候只写16个字符（不满16我直接填0了）

（所有于卡有关的操作都是通过硬件实现，程序只是实现串口交互和命令定义而已

界面的使用过程：1.先是（不必须）点击Check按钮，在INFO TIPS富文本区会显示当前选卡与否，选卡成功则显示 MIF card is ok(选卡是通过硬件操作的）

　　　　　　　　2.必须连接（Connect)成功才能读写操作,先输入扇区号，我这里是1号扇区，然后点Connect botton 如果验证成功返回验证成功

　　　　　　　　3.读操作和写操作必须先输入地址或数据，然后在点击Botton

贴上相关代码，仅供参考（注释没怎么搞，代码有过修改，所有有的地方注释还是错的，请不要介意）

需要注意的是，对于界面交互的程序而言，需要做到，界面文件和业务逻辑文件分开，比如界面文件demo.py（一般由demo.ui转过来），业务逻辑文件：calldemo.py

当然这下面的代码，缺少一个serconfig的文件（这个就因人而异了）还有我只给出C代码的命令处理的程序，只提供一个思路而已

还有一个扩展的功能，我没做，就是MIF_HALT这个功能，可以实现，不用移卡就切换扇区（当然这个命令是暂停卡的功能）
