Pulse Gen

Hi Mariss Jon, and the list,

I was looking at new posted files on CCED, and revisited your (Mariss)
pulse generator block diagram (PulseGen.Doc). Do I understand that it
is possible (and a proper way) to do coordinated moves between multiple
axis by setting up a "pulse generator" for the three required rates,
generate (or count) the needed steps in the major axis (farthest
travel), and all axis get there? Is that the intent of your circuit,
and do I understand that you have a circuit that you wouldn't mind
posting for this? I saw a very old circuit that used 8253 timers to
generate rates and count steps for 3 axis, and built one of my own (wire
wrap!) for a robot back in about '84, but didn't do much with it. I
have also thought about using 3 Cy-545's to generate profiles for up to
3 axis, although I'm not sure how accurate the rates can be generated.

I know Jon is also working on a board that can generate rates. I would
like to go one of these 3 (?) ways, after looking at the software-only
approach! Yeah, it can be done ;>o

Sometime soon I'd like to get some hardware!
