Mike,
U11 is the motor driver nearest the start button that drives motors 2 and
3.
The #2 pin is the second pin back on the chip nearest the start button.
See page #2 of the Handyboard assembling manual.
I followed Tom Brusehaver instructions at the
handyboard/software/contrib/tomb/readme Be carefull not to reverse any
wires and you will do just fine.
I have the v2x socketed on a pref board ,code loaded and the thing works
just fine. When I type at the IC prompt v2x(); it constantly prints the
current heading.
My problem is not knowing enough about writing code. I would like my bot
to go in one direction for a number of wheel rotations then
another-----ect. I don't think the compass is going to work very well
inside but should work fine outdoors.
Please let me know when you when you get a workable code. If you could
share a working code I could change variables to suite my needs.
Good Luck
Terry P. Gathright
