Fred, I double-checked, and my " main() " program (filename: jrm1.c) is all lower case letters. I confirmed case sensitivity by trying to call the " main() " file (filename: jrm1.c) which has been downloaded to the HB by typing " Main() " on the PC. (...)

I wonder if it's because you've capitalized "Main()". C is case sensitive so main != Main. try it making your main program lower case and see if that works. Fred (...) (23 years ago, 30-Dec-01, to lugnet.robotics.handyboard)

John, a couple things. 1. when you quit and restart IC, it forgets what programs you may have loaded into the HB. so that explains your #4 case below. 2. IC has its own way of storing vectors for user code like your main() program, so you should not (...) (23 years ago, 30-Dec-01, to lugnet.robotics.handyboard)

(a little late for X-mas, but maybe in time for New Year's...) As many of you know, when I was at MIT one of the last things I worked on (from 1996 to 2000, actually) was a tiny robotics controller called the Cricket. In May, 2001, I obtained rights (...)

I'm looking for two of the IS1U60 sensors for the Handyboard. Anyone know where I can purchase them? The only place I could find that carried them would only sell them in lots of 1000 pieces. If you know where I can get a couple please let me know. (...) (23 years ago, 20-Dec-01, to lugnet.robotics.handyboard)
