 | | New Servo Routines?
|
|
Because I have an expansion board, I cannot use my hacked up servo motors together with unaltered motors. In order to stop the hacked servos, I have to call init_expbd_servos(0) which dis-allows use of the other ones. Does anyone have any asm code (...)

hi, we have to generate a square wave for a pizeo buzzer, we would use the one on the handyboard, but this one has to be encased in a shell, which would only be unable to fit the handyboard. we tried just switching a digital out, on and off, and the (...)

gary -- it's an interesting bug. as you say you've got two 2-dim arrays, i can surmise that you're using Newton Lab's version of IC. In which case, they'd be the ones to address this problem. re: mailing list, it's now administered through LUGNET. (...) (24 years ago, 16-Apr-00, to lugnet.robotics.handyboard)

This isn't technically a Handy Board problem as my code is being run on a Rug Warrior look-alike. However, I suspect that the same problem I'm experiencing would happen on my Handy Board if eviscerated one of my other robots and tried it. (...)

I'm indebted to Randy Sargent who sent (...) (24 years ago, 15-Apr-00, to lugnet.robotics.handyboard)

Thanks for the tip. I think you are right.

I am planning on building a (...) (24 years ago, 15-Apr-00, to lugnet.robotics.handyboard)
