PoMoCo.py

Hexy Questions, Problems and Suggestions
#1

I uploaded Servotor32 2.0 to the PoMoCo board. Verified that’s what’s running using the serial monitor and the V command.
When I run PoMoCo 1.0 (which worked with Servotor 1.7), I get the following traceback.
I’m using a Macbook Pro OSX 10.7.5, python 2.7.3 and pyserial 2.6.

Any ideas what’s wrong?

Commenting out line 113 in GUI.py (l2.pack()) seems to fix the problem.
Googling seems to indicate that grid and pack shouldn’t be mixed.

Am I using old code?

Thanks,
Greg
