AVR-Chat

Chuck,

I had some discussions with Martin Hebel when he was initially 
developing his StampPlot product.  Although he wrote it primarily for 
use with the BasicStamp that he uses in his classes, he did write it 
generically enough that it could be used with any serial data enabled 
product.  I believe they have a trial version on their web site if you 
want to download and give it a workout.  Martin is also very willing to 
answer any questions you might have about the product.

I tried...but just couldn't pull him away from the dark side.

I just bought a book titled "Excel by example" that is supposed to be a 
tutorial text for using VBA with Excel to do a variety of tasks, some of 
which include logging external data via a serial port.  You might check 
that out too.
