使用制造商的 DLL 通过 USB 控制步进控制器，使用C++

简介上完大学课程后，我正在复述自己的C++。我最近买了一台Arcus Performax PMX-4EX-SA-TB9步进电机控制器，它有一个USB连接，我计划使用它。该公司提供使用其专有代码手动控制步进器的软件，并在其软件中提供一个终端，您可以在其中向控制器发送单行代码以控制步进机。你可以控制加速度和最高速度以及各种各样的东西。玩起来很有趣，但现在我想走得更远。在线手册谈到了使用C++为步进器编写自己的程序，我下载了我认为需要的文件。我有一个DLL文件、一个lib文件和一个头文件。因此，我了解到DLL文件是一个动态链接库，它在可执行文件的运行时使用。我已经通读了lib文件和头文件，在头文件中发现了一些我认为类似于一些马达命令的函数声明。我将在下面插入头文件。

我的问题

我可以使用DLL文件以及lib和头文件来控制这个设备吗？我该如何加载这些内容？有人愿意使用下面包含的fnPerformaxComDoMove函数写一个简短的小例子吗？这样我就可以从那里走了？我使用的是Visual Studio C++2013，我已经完成了关于创建和使用我自己制作的DLL的在线教程，但与此相比，这些似乎都很简单。

我对的理解很差

我相信，由于我得到了一个DLL、头和lib文件，我将使用_declspec(dllexport(定义，而不是导入版本。所有的函数声明都以"BOOL"、"PERFORMAXCOM_API"、"_stdcall"开头，我只习惯于看到一个类型、一个函数名、然后是括号中的参数。在所有不同的函数前面，"PERFORMAX_API"answers"_stdcall"是什么意思？我知道DWORD是双字，是一个32位整数，但有些参数要求一个轴，比如x、y和z……当他们本可以只要求一个字符时，为什么他们想要一个数字？非常感谢任何能为我提供任何信息的人。我非常想学习如何使用这个。
