Re: [CAD_CAM_EDM_DRO] Basic Stamp + Encoder

Hi Terry,

I have not done any PIC programming but have worked for large computer
manufacturers (CDC and now Cray) for years and have been programming in all
languages since about 1968. I think programming for a PIC would be a nice
change of pace!

I need a DRO for my Bridgeport and plan to make one eventually using a PIC
to do the counting and drive the display. I have looked at the code for the
PC based DRO systems and see that it keeps a history of the last few encoder
transitions - I think this is an attempt to avoid missing transitions. The
way it is done uses either a lot of conditional code (which will slow the
program down) or a large table (which will not fit in a PIC memory). I don't
think this history is really necessary.

I would like to see the code you have for PICs. It will give me another
example to study and hopefully convince me that the history stuff is not
necessary.

Regards,

Dave.
