I do software for food, but I very rarely use debuggers.
I find that for real-time stuff they just don't help much
unless they have configurable full-speed trace buffers (which
is pretty rare on low-end JTAG parts like the '430).
Looking at the code and thinking is usually the best/fastest
way to find problems (sometimes aided by the insertion of a few
lines of code to toggle a spare port pin in key places).
Debuggers are OK to do an inteteractively examine memory once
you've stopped execution, but I find things like
single-stepping are pretty much useless: once you've stopped
execution, you're done. You can't stop time from passing for
all of the perpherial parts, so the system is dead.
