I have.  Not debugging basic C code or basic C language questions, but 
questions about DSP and how to implement the math.  I'm not sure how what
kind of questions a person asks matters, we have people who've never held
a soldering iron to people that can design entire boards (or programs)
and everything in between.  The kinds of questions asked tend to depend
on the person's experience and education.

I can and do use basic DSP blocks the same way I would use ADSRs, VCAs, 
filters etc. to  make a hardware design.

Like a VCO might need some rework to make it work on +/- 12v instead of 
+/- 15v, I take such code and rework it to fit my design.  I see far more
similarity than I do differences and I find the differences to be trivial.
