我正在尝试使用 c++ 和 Qt 与通过 GPIB 连接到 Windows PC 的 Yokogawa GS200 DC 电源进行通信。

我从横河电机 ( https://y-link.yokogawa.com/YL008.po?V_ope_type=Show&Download_id=DL00002096&Language_id=EN ) 找到了一个应该完成任务的库；但是，当我尝试运行一个简单的代码时，它编译时没有错误，但是没有输出或任何函数已执行的迹象。我只会得到“按 <ENTER> 退出此窗口”

我不确定到底出了什么问题，有人有什么想法吗？

代码和头文件如下：

主要的：

#include "tmctl.h"


 int main()
        {

     char adr[100];
     int  ret;
     int  id;
     char buf[1000];
     int  length;


ret = TmcInitialize( TM_CTL_GPIB, "11", &id );

if( ret != 0 ) {
    return  TmcGetLastError( id );
}

ret = TmcSetTerm( id, 3, 1 );
if( ret != 0 ) {
    return  TmcGetLastError( id );
}


ret = TmcSetTimeout( id, 300 );
if( ret != 0 ) {
    return  TmcGetLastError( id );
}


ret = TmcSetRen( id, 1 );
if( ret != 0 ) {
    return  TmcGetLastError( id );
}


/* sending *RST */
ret = TmcSend( id, "*RST" );
if( ret != 0 ) {
    return  TmcGetLastError( id );
}

/* *sending IDN? & receiving query */
ret = TmcSend( id, "*IDN?" );
if( ret != 0 ) {
    return  TmcGetLastError( id );
}



ret = TmcReceive( id, buf, 1000, &length );
if( ret != 0 ) {
    return  TmcGetLastError( id );
}


        }

除了 .dll 文件之外，函数和变量的描述可以在此处的库文件夹中找到。

当然，我也曾经LIBS += "...\tmctl.dll"将库链接到我的项目。

好的，所以代码正在运行。我不确定如何（它与我在上面的代码完全相同）。

唯一的区别是我尝试使用 VS 运行代码，为此我将 dll 文件添加到 (C\windows\system) 目录。在它在那里工作之后，我想在 Qt 中再试一次，结果它居然奏效了！

虽然我怀疑系统目录中的 dll 文件有什么影响，因为当我将它包含在 Qt 中时，我引用了另一个位置。

如果有人有任何见解或理论，请随时分享。
