![]() It would be nice if keygrabber actually showed analog input levels, instead of just indicating which input is being exercised. I think this problem is either with Keygrabber, or Mach3. I did try hooking up one side to ground, and it still worked, but the results were very strange. Check around at all the info on joystick/gameport interfacing, and you'll see that. ![]() ![]() ![]() The pot resistance is read by the length of time it takes a capacitor to charge up. The wiper goes to the input, one side goes to +5, and that's it. I just got some 40-pin 18F4550's ($4.40 at Newark), which have all kinds of analog and digital inputs, and a built-in USB interface.Īs to the pot connections, strange as it may seem, the pots are not connected to ground. Perhaps I will build my own 'Pokey', using a PIC microcontroller. I may wind up spending much more than that trying to figure this problem out, but it will be a learning experience. However, the idea of having to buy an $80 device in order to do one simple thing does not appeal to me. I looked at the Pokey device, and it looks very nice.
