You could be right, I just remember someone on this message board had one and said it just sent "left" or "right" output to the encoder when I had asked if you needed 12 distinct outputs for such a device. I guess I'll have to call Happs!

: : From what I understand they hook up to your keyboard encoder like a normal stick. Besides the four directional signals they also send one for rotate left, and another for rotate right, so they stick uses 6 outputs...
: I don't think that's how they work. The 'clicky' rotary sticks put out something more like a 4-bit binary word to respresent the rotated position of the stick (looking at the drawing for those sticks again, it may just ground one out of 12 leads to show the position). You'll need to have a circuit look at that binary word and how it changes when the stick is rotated to make a single 'just turned left' or 'just turned right' output.
