使用inpout32.dll进行Visual c + +并行端口访问 [英] Visual c++ parallel port acces with inpout32.dll

问题描述

我想构建一个小应用程序，它可以控制连接到并行端口的一堆led'。从我通过互联网阅读的内容来看，我已经知道我必须使用Inpout32.dll访问该端口。



>我已经下载了''Inpout32.dll''和''inpout.lib''，现在我如何将它包含在我的visual c ++项目中。我正在使用Visual Studio 11 Ultimate，我正在制作一个c ++控制台应用程序。



>我必须使用哪些功能将数据发送到并行端口？



>除了 http://www.lvr.com/parport.htm <之外，有人能指出一个好的，清晰的，清晰的教程/示例吗？ / a> [ ^ ]

Hi, I want to build a small application that can control a bunch of led''s connected to the parallel port. From what I''ve read over the internet, I''ve come to know that I have to use Inpout32.dll for accessing the port.

> I have downloaded ''Inpout32.dll'' and ''inpout.lib'', now how do I include it in my visual c++ project. I''m using Visual Studio 11 Ultimate and I''m making a c++ console application.

> What functions do I have to use to send data to the parallel port?

> Can someone point me to a good, lucid, clear tutorial/example other than http://www.lvr.com/parport.htm[^]

推荐答案

请参阅此CodeProject文章： VC ++中的硬件接口编程 - 第一部分（端口访问） [ ^ ]。

Please see this CodeProject article: Hardware Interface Programming in VC++ - Part I (Port Access)[^].

我写了这段代码：



#includestdafx.h

#include stdio.h

#includestring.h

#includestdlib.h

#include< conio.h>



短_stdcall Inp32（短PortAddress）;

void _stdcall Out32（短PortAddre ss，短数据）;







int main（int argc，char * argv []）

{





Out32（888,255）;

system（ 暂停）;

Out32（888,0）;



返回0;

}





这不应该首先打开所有led'然后关掉它们吗？什么也没发生。

I wrote this code:

#include "stdafx.h"
#include "stdio.h"
#include "string.h"
#include "stdlib.h"
#include <conio.h>

short _stdcall Inp32(short PortAddress);
void _stdcall Out32(short PortAddress, short data);



int main(int argc, char* argv[])
{


Out32(888, 255);
system("pause");
Out32(888, 0);

return 0;
}


Is this not supposed to turn on all led''s first then turn them off? Nothing happened.
