HELP: Reversed X-Axis on Trackball?!?
njchan:
I have a Happs Trackball with PS/2 interface PCB.
I've got it working in Windows for the most part ... only problem is the x-axis is reversed for some reason. Meaning ...
when I move the ball up and down the cursor moves up and down ...
but when I move the ball left, the cursor goes right ?!?! wtf?
and when I move the ball right, the cursor goes left ?!?!
anyone know how to fix this? I tried reversing the connector on the trackball to PS/2 interface, but that didn't do anything.
any ideas?
Rocky:
You need to swap a couple of pins on the Happs optical board.
Mark70:
If you followed the instructions on the Optipac site, they're backwards. They say where to connect the wire by colour for a happ trackball. I followed it too and had the same results. Just swap the x wires and the y wires.
Either that or you installed the track ball with the arrow that points to the monitor the wrong direction.
TOK:
You mounted the trackball backwards. Flip it around.

Nope... turning the trackball around 180degrees will result in the up/down axis getting reversed. Somehow the lef/right leads are backwards. I made my own mouse hack for my trackball, and did this exact thing by accident. switch the pins for left/right, and voila it works fine. If BOTH axis were moving the wrong way, then turning it around would fix it.
