Hi all,
I've purchases SFE's trackball and breakout board
http://www.sparkfun.com/commerce/advanc ... ll&x=0&y=0
Has anyone actually made one work? It seem's I'm having a problem...
I can detect the button work (Sel1 & Sel2)
I can detect the "X" movement using XSCN, XO and XO'
I cannot detect "Y" movement using YSCN, YO and YO'!!!
I have traced the connections from the pic all the way to the ribbon cable, and the connections are solid.
I purchased 2 trackballs and breakout boards, and both have the same issue. I'm sure there is a wiring issue on my side....
This is how the "X" is wired.
GND --> XSCN
XO --> pic pin B1
XO' --> pic pin B2
I have internal pullups on the pic pins.
This works great, I can see the 010101010101's happen correctly.
Now when I do the same for the "Y" side, nada!
Any thoughts?
