Some documentation on usage needed.

[GoogleCodeExporter]

I've looked at the soft, and I think it is very good and useful, but I do not 
know what all these controls are about. What does trigger field specify, what 
is time(ms) field, and what is a no-named field with 0.0002 selected by 
default? What are the 2 channels and how can I stuff data into them from my 
arduino? 

Frequent users of ordinary oscilloscopes probably know all these things, but 
since the project also aims at arduino developers (who like me might not be 
introduced to signal analysis) it would be good to have some manuals on that 
things do what.
