Re: [CAD_CAM_EDM_DRO] PICs as replacements for L297s

I have parts in house. I have a circuit drawn, code written and the emulator
bondout board for the new parts. But have not had the time to wire up the
circuit and test the code yet. I'm about another week from having my
workshop built and then I can do more fun things other than put a metal
building together.

So, I'm probably 2 weeks from having a working circuit and code. I'm doing
this with the PIC16F628 part.

later,
Larry E.
