I found this by experimenting, so it's possible these are not the approved pinouts, but they work. (Hint, when it smokes, you've got the wrong pins :-) Pin Function ----------------------------------------------- 1 +5 V 2 Stick A, top button 3 Stick A, x position 4 ground 5 ground 6 Stick A, y position 7 Stick B, top button 8 ???, maybe +5 V, but it shouldn't matter 9 ??? 10 Stick A, back button 11 Stick B, x position 12 ground 13 Stick B, y position 14 Stick B, back button The buttons are connected as simple switches between +5 V and the button's pin. (Or between ground and the pin, I don't have it written down. Try it, that by itself can't hurt anything). The position potentiometers are connected with the fixed resistor part (the outer pins of the potentiometer) connected to ground and +5 V, and the variable part (the center pin) to the position's pin. Hope this helps. As always, if you blow up your computer, it's not my fault. :-) -Josh Mastronarde -jm9t+@andrew.cmu.edu
