Hey, I was wondering whether anyone knew of a Handyboard simulator. I am working on a group project where each person develops code in C using IC for the Handyboard. The problem is that we have only one handyboard and thus only one person is able to (...) (26 years ago, 15-Apr-98, to lugnet.robotics.handyboard)

Nevermind my last message. I had a phone cable that was dodge. Out of curiousity...Is anyone on this list familiar enough with C to make a program that you could input wheel diameter and wheel base along with the weight of the robot and reference (...)

Hey. I just got a couple more handyboards and both of them had exactly no power in them. Ive let one charge for about 12 hours and then tried to use the Initialization app on it and it wont synchronize with the board. Does anybody know what im doing (...)

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 (...)

| | Big adapters?
|
|
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)

(...) Mar, I ran into these warnings when I was modifying sencdr0.asm. They do in fact show a bug in the assembly code, but it's harmless.

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.
