Over the past two days I have had two problems with my HB that I can't
explain. Maybe you you can help.
1. I wrote a simple program to test out my motors that consists of the
motor, sleep, and beep commands. Once in a while I get an error back while
its runing saying "stack overflow 22 bytes" or something like that. I have
no idea why it does this but it only seems to do it with programs that
control the motor.
2. This problem really threw me! I was testing software to run the
Poloroid sonar system and once in a while the board would reset. I thought
that it was because the sonar was powered off the HB power supply so I
connected a 470uF cap accross the leads but that didn't cure it. Here is
the strange part. I had the equipment on my desk and while I was sitting
in the chair, it worked fine. As soon as I stood up it would reset! The
only thing that I can think of is static buildup but the chir doesn't touch
the desk and the desk is well insolated (sp).
I hope that someone can help. Thanks.

| Could anyone tell me what type type of accuracy/precision you get from the vector2x compass? Does it just return n,s,e,w,nw,ne,se,sw, or a byte? Is there a datasheet somewhere on the web? Thanks for the info! -=Fred Cass=- (27 years ago, 15-May-97, to lugnet.robotics.handyboard)
