Aha, the flame war has begun :-) I agree with you too Ben, only a fool
would spurn the analyser, but if you instrument your project properly
and really KNOW the system, you can often get by without one.
I have LOTS of experience with logic analysers and they are very useful.
Unfortunately they are generally too expensive for independent
consultants (like me).
As an engineer with extensive hardware and software background, my
favorite logic analyser story ended by showing the lead sofware guy on
a project where his code was failing, and then having him duplicate
it on his emulator! My part of the project was a controller communicating
with an intelligent remote module. I knew my stuff was right and the onus
was on me to prove otherwise. I could never have done it without
the analyser.
Nuff said, and I've GOT to get some free time to play with a Mindstorm...
Now that there is an independent OS, it's a LOT more interesting....
