Hi all, Futaba servo's chatter when the pulses are not updated quickly enough. At best, this produces a slight buzz, at worst they 'hunt and seek' their position a tiny bit. I don't know how fast the HB routines update the pulse, but standard (...) (26 years ago, 14-Apr-98, to lugnet.robotics.handyboard)

I have noticed in my experiments that the HB servo routines don't interact well with the LCD. In order to get them to work reliably in my Handyboard library I redesigned the way the LCD driver worked. Unfortunately for you that library was built for (...)

|
|
Hello all, I'll just briefly restate my earlier questions for ease of responding: 1. Why are we encouraged not to use big adapters (>1A) for the HB? Is it because of the charging circuit, or does it fry the board? 2. Can I plug a big adapter into (...) (26 years ago, 14-Apr-98, to lugnet.robotics.handyboard)

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 (...)
