I just found a second SEGA-controller and tried that. And that also has some glitchy behaviour.
It glitches a bit different though. If I press "start-button" on that controller it also inputs random values, but only randomly scrolls from right to left while inputting these random values. Not down and to the left as my other controller did.
What I think is strange, is that if I must believe this schematic:
https://gamesx.com/wiki/doku.php?id=cont...ntroller_3
The UP and DOWN buttons on the controller are going (almost) straight into the NerdSeq... And are not connected to the START button except for the resistor-array. And when using them to navigate the NerdSeq also works as expected. I will try to see if the problem is in the resistor-arrays (of both units) if I have some laying around.
Otherwise I suspect the scanning of the button presses... I'll go and measure thing now.
This all isn't a big problem for me though, I never really use the controller anyway. I just tried because I had an idea of connecting/hacking some encoders to the controllers, because Hein wanted to use euclidean input with a knob, to have instant snare-rolls in live situations... I thought of hacking it with the I/O controller-port... That's when I noticed it wasn't doing what I wanted, and was a bit bitchy-glitchy.
---------------------------
Edit: It can't be the Resistor-Array in the controller, because both controllers just have 9 separate 10K resistors instead. There is a 100nF (I think it is decoupling) cap in there as well. I will see if replacing that will solve me problem.
--------------------------
Edit: Edit: Nope, it wasn't the decoupling caps either. :_(
