(...) I'm doing signal conditioning for pan/tilt and (ultimately) drive/steer signals from an RC receiver and driving servos with the processed signals. All power for the servos is external, so all I need is signals through the Handyboard. -mike * (...) (29 years ago, 25-Mar-96, to lugnet.robotics.handyboard)

Is it possible to use any digital output on the Handy Board without loosing the monitor (or anything else for that matter)? Scott sherman@plains.nodak.edu (29 years ago, 25-Mar-96, to lugnet.robotics.handyboard)

| | Re: Driving large motors with the Handyboard
|
|
(...) Thanks for the tip. I got a hold of the book and read some of it. :) I was wondering if sending pulses to the motor would cause "choppy" rotation....or does it occur so fast that inertia effects make it "smooth". Also, with an h-bridge, is it (...) (29 years ago, 25-Mar-96, to lugnet.robotics.handyboard)

Mike, Out of curiosity, what are you using the pulse trains for? (If you're running multiple servos, I think I know a single-chip hardware mod to drive up to 8 servos from a single timer output.) -- Randy (29 years ago, 24-Mar-96, to lugnet.robotics.handyboard)

AAAARRRGGGHHHHHH!! After the pain of relearning assembler and getting interrupt routines to work, it seems my assumption of the availability of TOC 2 & 3 is incorrect. I need 2 (wanted 4) pulse trains to go out. According to the diagrams Fred (...) (29 years ago, 24-Mar-96, to lugnet.robotics.handyboard)

Take a look at the schematics, which are linked from the top page of the Handy Board web site. The info you are looking for is in the CPU / memory schematic. For the DC Motor outputs, the board uses a separate output latch---not the timer outputs. (...) (29 years ago, 24-Mar-96, to lugnet.robotics.handyboard)

I am wondering if anyone tried to write an IC program for DC motor position control using PID/P or whatever with a handyboard. I am also looking for a good precision DC motor (with encoder and gearbox integrated), I very appreciate your help for any (...) (29 years ago, 24-Mar-96, to lugnet.robotics.handyboard)
