| | Re: Servo Routines
|

When I see the servo chatter, the knob is returning the same value. In fact I can just set a constant unchanging value without using the knob and get the chatter. I've tried this on two HB's and get the same results. The servos are small Futabas. (...) (26 years ago, 13-Apr-98, to lugnet.robotics.handyboard)

can you ascertain whether the knob is returning the same value every time through the loop? i wasn't clear if "even when the knob is not changing" meant just that you weren't turning the knob, or whether you were sure it was always producing the (...)

Hi Armeen, I have the same problem as you. I thought my HB was faulty or it doesn't work with the 68hc11E processor I use or something. So what I did was: I wrote a very simple IC-Routine.

Hi guys, I needed 16 digital outputs for my handyboard, so I put up a very simple expansion board the way Fred suggested in his handboard FAQ: I connected two more hc374 with their d-inputs to LCD-display's data bus (d0 - d7).
