Re: [CAD_CAM_EDM_DRO] Re: PICs as replacements for L297s

A number of people say they have gone through the torment of programming
PICs to drive steppers etc., so how about someone sharing their knowledge?
This is, after all, the purpose of this list and I'm sure there are others
who, like me, would love to try out a PIC circuit but don't have the time
(or, in my case, intelligence) to learn the necessary skills to program the
PIC but who could, nevertheless, build a simple programmer and the rest of
the driver circuitry if the PIC code were available. I'm not suggesting that
anyone particularly divulges any 'trade secrets' - there are probably dozens
of ways the same effect can be achieved, but, in any case, even the trade
guys may learn how to do 'better, cheaper, faster' from such shared
knowledge which would be to the advantage of us all.
