Trackball Y-axis inverted, Happ ball/Mini-pac

(1/1)

 :dunno

I was wondering if someone could help me. I have a Happ trackball on my panel using an Mini-Pac interface and the Y-axis is inverted. The X-axis works correctly.

Edit: Mini-Pac, not Opti

severdhed:
i have not worked with a minipac before, but this one should be fairly easy.  a trackball has 6 wires:

1 = 5v
1 = ground
2 = Y axis
2 = x axis

all you should need to do is reverse the two wires for the y axis and you should be set.
