我正在帮助一位朋友完成最后一年的项目，他有一个我们想使用 C++ 程序打开和关闭的电路.

I am helping a friend to finish a final year project in which he has this circuit that we want to switch on and off using a C++ program.

我最初认为这很容易，但我未能实施此程序.主要问题是

I initially thought it would be easy, but I have failed to implement this program. The main problem is that

  • Windows XP 及更高版本不允许直接访问硬件，因此某些网站都在提示我需要写驱动或者找驱动.
  • 我还查看了一些在线项目，但它们似乎适用于 Windows XP，但不适用于 Windows 7.
  • 另外，大多数项目都是用我不熟悉的 VB 或 C# 编写的.
  • Windows XP and above don't allow direct access to hardware so some websites are suggesting that I need to write a driver or find a driver.
  • I have also looked at some projects online but they seem to work for Windows XP but fail to work for Windows 7.
  • Also, most projects were written in VB or C# which I am not familiar with.

问题:

  • 是否有适用于 Windows XP 和 Windows 7 的驱动程序，如果有，我如何在我的代码中使用它?(代码片段将不胜感激)
  • 是否有一种跨平台的方式来处理与并行端口的通信?
