[Robotgroup] GPS unit (was: Restarting in mid-script..)

[Paul Atkinson]

Sounds like quite a project!! I'd like to learn more about how it is all coming together.

I'm jealous, my wife made me clear the kitchen table, so no projects for a while.

It's still too early to tell.  So far, I have a bunch of different
microcontrollers and electronics (AVR ATMEGA162, Pololu SSC, RS232
converter, H Bridges, odometry circuit, +5V power regulator, and the
GPS) spread out on my kichen table with the robot under the table up
on blocks and the whole thing barely glued together with a mass of
"don't breath on it too hard" cabling.  Since I haven't moved the
whole works outside yet, I can't get real GPS readings.  Though, I can
state with confidence that the Parallax GPS reliably sends continuous
0's from my kitchen table. :)  Seriously, I have the code written for
the AVR to process the GPS NMEA input but it is pretty large due to
the inclusion of the C floating point libraries.  I may end having to
rewritie it to get the code size down.

So far, I have been concentrating on the basic drive mechanisms.  Once
I have that working a little better and all mounted onto the robot
base, I'll be able to then work on integrating real-time GPS data.
