PCI并行端口通信 [英] PCI parallel port communication

问题描述

我的计算机上没有安装pci并行端口卡，所以在计算机上安装了pci并行端口卡.分配给端口的地址是c100-c107.由于dll接受短数据类型，因此我无法将此地址传递给inpout32.dll.
请帮助我

解决方案

short是16位dtaatype，但已签名-因此您不能轻易使用最高位，您将得到如果直接尝试，则会出现编译错误.
请使用ushort代替:

  ushort  u = 0xC106;
Console.WriteLine(" ，u); 

I have installed pci parallel port card on my computer as my motherboard does not have one. The address assigned to the Port is c100 - c107 . I am unable pass this address to inpout32.dll as the dll accepts short data type.
Please help me

解决方案

short is a 16 bit dtaatype, but it is signed - so you can''t use the top bit easily, and you will get a compilation error if you try directly.
Use a ushort instead:

ushort u = 0xC106;
Console.WriteLine("{0:X}", u);
