i used some software called ws_logo, but i lost it
can anyone help me?
any software to control a robot conected to printer port?
any visual basic files to make my own program?
Umm... Sorry if I got you excited making you think you got an answer when you saw that there was a reply. But, I just wanted to say, I just came here to the Robotics Forums looking for this exact thing. And this was the first thread I came to. So, anyone, I need the same thing. Information on writing my own program to control my robot via the parallel port.
Here's a link for programming parallel port.

(There are a few links on the page and two of them are for programming parallel port via QBasic and Visual Basic). Have fun.
Heres a circuit i designed and built a couple years ago which is used to control 4 motors from the parallel port of my computer. I used QBASIC for programming but just about any language will do.
Personally, my tip would be to use Linux and Perl.
Linux treats every device like a file, so writing code to communicate with hardware (such as a parallel port) and send data to it is extremely easy. Also, your hardware requirements are extremely marginal with Linux. A 386 with 8 meg of ram will be more than suitable for console operation. If you decide to go this route, check into Debian Linux. It's the most complete distro I have seen so far. The full installation runs on 7 CD's. It goes without saying that you can install off one as well. Debian comes off the shelf with some very nice schematic design software as well, although I forget what it's called. Another plus to Linux is the fact that it's free. Debian can be downloaded free of charge from the website https://www.debian.org.
The reason I suggest perl is it will simply make it easier. You open a filehandle (the port), pack the data and write it to the filehandle. It's all that simple. If you feel ambitious, using the Tk library, you can design a GUI interface to work with XWindows as well.
I started with Qbasic something like 10 years ago. As one that has written in both languages as well as C and C++, I can honestly say that perl is the easiest language I have worked with while still retaining a lot of the power inherant in a C language.
This is mearly the method I would choose for a similar project. In my opinion, this would be the most simple and easiest method while still allowing the designer the greatest flexability possible while keeping a low budget for hardware. Most of the time you can find someone willing to give you an out of date computer that will work just fine for this. However, it goes without saying to use what ever method you are most comfortable with.
Sorry to bother you so much , but I actually got the dll file but now dont know how the program works, some one could you explain me, if posible could you also send me the source code

wanna know how transistors work?
could help you if you want to...
the emitter has to be fitted on the ground, while the basis is connected to the signal and the emitter goes to the part that needs to be amplified... but there is so much literature, specially in the internet you could've used, why didn't you do that??

hi
i already programmed the port with pascal, but unfortunately my teacher wrote a pascal-unit for this, and its german. he also named the functions/procedures very strange and near to the projects he had there (he called one 'motor1_left' to turn the motor left (a1=0/a2=1)) and so on. if anyone wants to have it anyway, download @ www.fhn.de/~gfmeyers/deppe/
there is also a turtle-graphics unit (640*480).

I've done quite a bit of parallel port interfacing but I was wondering if there was a to get more than the 8 outputs. I know you can use additional pins and get about 12, but I'm looking for 50-100.
Is there any chip that'll take say when pin 2 and 8 are high, it'll make output pin 20 on the chip high? Anyone heard of anything like that? By using combinations of high pins to make 1 final pin high, you should be able to many, many more than 8 possibilities.
yes, you can use a multiplexer IC such as a 74154, this will give you 16 possible outputs and if you use two, you can get 32 outputs all driven by the parallel port data pins 2 to 9. The problem is only two outputs can be high at the same time, but that may be fine depends on the application.
