Oh, this may also not the only problem but I'm pretty sure your loop function is a no-no. You need to define a function that sets the matrices once, the use a timer to have it called repeatedly.

Using default port parameters?

It looks like you're mostly using the default values for the serial port parameters (baud rate, parity, and so on). It might be worth checking that these defaults are the same in pySerial as they are...

Yes, figuring out how to build complex C/C++ projects is a hideous nightmare, particularly on Windows with its plethora of compilers. That's why sane people prefer Python. ;)

In your script (or at the Vizard Python prompt) type:

import sys
print sys.path

That will tell you where it's looking for modules.

On this page and for viz.phys.intersect() it states that the function returns a VizIntersect...
