Thread: sony joystick??

check out this link...... I think it might be on the track of what you are after....

not english, but a circuit diagram and a winamp plugin screenshot.... should give you a good hunting start.....

Funny, I just happened to post about it in another thread.



It's actually an "analog" device. Every switch activates a different resistor, except for one, which is a "true" button. So you wire it up to the joystick port, and read a joystick axis to tell which switch has been pressed. Anyway, I've got it working, based on info I found here:

You have to put together a small circuit for the joystick port, _AND_ write some software. Unless you use XMMS under Linux -- in which case just get the XMMS module on the page above.

No, it won't work with Winamp plug-ins, at least not until someone writes a plug-in specifically for the Sony. (Aren't there any Windows programmers on this forum? Hello?)

Reason is, the Sony works by shunting in a different resistor for every button. To the computer, it appears as if a joystick has been moved along the X axis to a certain very precise position; every button corresponds to a different position... it's a fairly unique setup, so no generic plug-in will work.

Wow, my neurons are firing faster than a gatling gun.

If you could let me know where I can find a circuit diagram for the Sony joystick, I'm 99% sure I could creat an interface circuit to allow it to be used with the existing joystick plugin, or even a key pad plugin

On the side my idea is based around using the resistors as a potential divider, the output of which is connected to a series of comparitors, which then goes through some simple logic and into the PC, cunning!?!?

Could one of the sparkies out there coment on this idea and possible recermend a comparitor chip.
