Hi,

Does anyone know a good way to interface a microprocessor to the joystick port of a PC?
I found out that one can use an 'digital potentiometer' which is a chip that can be serial controlled and has 4 digital resister in it.

I have seen a german site where they sold an trainer-joystick interface based on an atmel uc, that had a little circuit witch a transistor and some other components between the uc and the joystick port (i forgot the url of the site).

Does anyone know an other cheap and small way to accomplish this?

Wow,

This looks very cool to me!!!
I just clicked the right link (in russian) and downloaded the .zip file with the source and everything in it....

When you've got the translation complete, can you send an email to me?

The very best regards,

Translation is ready. Download that file again.

The file that i downloaded (rc2joy.zip) doesn't contain english documentation, is this the wrong file?

Wow, that's it!
THX. If I have a question about this adapter, can I ask you? Is it easy to build it, or not?

by **schumi** » Sat Nov 10, 2001 9:21 am

Have you a list about all parts I need for building? And how get I the firmware on it? Need help for it!

by **Boxed** » Sat Nov 10, 2001 10:05 am

Thank you very mych for the translation, it's a lot better than the one i got from the online tranlation services... :-)

Just one question before i can build it, i can't buy the transistor KT3102 here. With what transistor can i replace it?

HEy Boxed!
You are from NL, right? Do you speak german too?
Hope so, I've many questions about this, I think you undertand that!

To Boxed:
KT3102 is a russian NPN transistor with beta > 100. You can use any andlog with same characteristics.

To Schumi:
I don't know, how easy will it be for you to build such adapter. I can say, that when assembled properly, it requires no tuning. Firmware is included in archive. Read the documentation carefully for all details. I have no partlist with exact details specs. Try to make partlist yourself from schematic.
