并口通讯 [英] parallel port communication

问题描述

我编写了用于并行端口通信的程序，但是我在构建电路时遇到困难
我必须同时连接两个并行端口1到1或与状态并行的数据引脚吗?因为我必须在它们之间连接LED以显示数据通信.

i wrote the program for parallel port communications but im having difficulties in building circuit
do i have to connect data pins of both parallel ports 1 to 1 or parallel to status?as i have to connect leds in between to show data communication.

推荐答案

那里这篇文章涵盖了使用并行端口的所有基础知识，包括硬件连接.对于代码，它使用C#，但是由于它调用inpout32.dll，所以对您来说应该不是问题.

There is an article here that covers all of the basics of using the parallel port, including hardware connections. For code, it uses C#, but since that calls inpout32.dll, that shouldn''t be a problem for you.
