python操作雷赛IO卡(IOC0640)

1.先安装板卡和对应驱动.(测试程序运行起来,没有问题即可.)

(顺便提一句:如果官方测试程序 | 示例,运行起来找不到IO卡说明DLL版本太新,换旧版DLL即可.)

2.官方例程给的文件打包成(C#的DLL,32 | 64和Windows 相对应;

(厂商给的DLL也是32 | 64 和Windows相对应)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

}

3.官方给的DLL还有上面生成的DLL复制到py程序运行目录.

4.不多说python贴上来 .

(import clr 之前需要install pythonnet ;下来C# | .NET那一套就能直接用了.)
