是否可以直接将传感器连接到并行端口而无需在c#中进行pic编程? [英] is it possible to connect sensor to the parallel port dirctly without pic programing in c# ?

问题描述

我想做一个项目
我需要在电路中连接传感器，但
我问我是否可以在不使用图片或微控制器的情况下连接它
希望直接将其放在并行端口的13和25针中，以输入到计算机.

感谢

i want to make a project
and i need to connect sensor in my circuit but
i asking if i can connect it without using the pic or microcontroler
like to put it directly in pins 13 and 25 in parallel port to get input to the computer.

thanks

推荐答案

这取决于传感器:pll端口是数字的:0V为零，5V为1.如果您的传感器输出数字数据并且可以应付+ 5V，则有可能.不过，根据功率要求(Pll电流非常低)，可能不建议这样做

此处 [

It depends on the sensor: the pll port is digital: 0V is a zero, 5V is a one. If your sensor outputs digital data and can cope with +5V, then it is possible. It may not be advised though, depending on power requirements (pll current is very low)

There is a basic description of how the ppl port on a PC works here[^]

我在CodeProject中看到了一件有趣的工作，显示了并行端口技术.哦，在这里:未经审查的I/O端口-1-通过并行端口控制LED(发光二极管) [ ^ ].
