Analog joystick help, buttons not working.

Dave S

Hey

I am interfacing a Analog joystick (Flightstick Pro, 1995) with my javlin, and I· have the X/Y axis working perfectly..

Using http://www.parallax.com/dl/appnt/jav/class/AppnoteAnalogJoystick.PDF· for help, I cannot figure out how to get the buttons working.· The class has support fo buttonX and buttonY, butwhen I run the program, debug says buttonX is not pressed, and Y is always pressed, and no matter what··button I press, nothing changes.· The joystick has 3 buttons onstick, a 4 dir top-hat, and a trigger.

Any ideas?· Is it possible that I need·to change the pins· around from the DB15F on the joystick to other· pins?

Any hints?

Jon Williams wanna jump· in· on this?? :-)

Sure, I'll jump in -- I think you need to crack open your joystick to deduce the pinout, or maybe you can find one on the 'Net somewhere. The joystick class works with old, simple X/Y/2-button joysticks (and they're really hard to find now).

Ok, what do you mean by deduce the pinout? I traced all the wires inside the stick, to each button, but after the AD IC's i couldnt figure out what pin they went to the DB 15F with, theres 3 analog to digital converters inside the stick. Later if I cant figure it out ill post a few pics so maybe you could better direct me?

Thanks

Although Im delighted to say, the XY axis worked perfectly the first time! But this stick has so many buttons, I have a feelings it will take a while to figure it out.. I need to find a place to get a few DB15F connectors, i snaped one off an old soundcard, so theres not much to work with and desodering will probably ruin it. hehe

It might be easier to open up the joystick....
