We just finished using the same comm. boards for our senior project, so maybe I can help a little. (...) One interesting phenomenon we noticed was that we received random noise at the receiver when the transmitter wasn't on. However, when the (...)

What I require is all the source code that's running on my handy board to be available. It's not the case for IC3.2, so I'm not (...) (25 years ago, 15-Apr-99, to lugnet.robotics.handyboard)

Well my code does make constant calls to printf() and motor() (although with the original PWM code). I did notice the jitters more on the low end. now I've put aside the head rotation and sonar routines and will start on the encoders. I am (...)

Eric/MSMKatz Newton Labs does offer smooth PWM routines for IC3.2. Check ftp://newtonlabs.com...mooth-pwm/ for details. I have used these with my handy board and expansion board (only simple test) and it worked fine. It does require some changes to (...) (25 years ago, 15-Apr-99, to lugnet.robotics.handyboard)
