I have all of my software running on PC in C language.
I just don't find it that interesting.
I'd like to find a micro that will handle all PID calculations
for me, so I can use the PC for other things like vision
I am a died in the wool IsoPod Addict ( www.newmicros.com ). A Plug A Pod
could to it with a lot of extra addit'l hardwaare available for other
things. A tini-pod or could do it too.
Using an embedded micro is a very good way to augment a PC based system.
Unless you go adding cards, writing your own dll's etc, a micro is the way
I see a lot of Pods being used for just this purpose. A little bit of
effort, and you can build a dedicated protocol for motion control , GPIO,
A/D, other timing , and even CANBUS communications.
There ARE ready-made controllers that do exactly this, but it all
depends on what you mean by a "reasonable price." JR Kerr has long sold
a set of PIC chips for motion control, with some fairly sophisticated
tuning parameters. Is $30 reasonable for the chip-only version of their
product? Seems to me it is, but others might consider that expensive.
They don't offer the source code, for obvious reasons, so if you're
doing a 10 axes animatronic controller, costs will add up. (OTOH, at
$50/hour for a programmer, that's only six hours of work. Cheap for a
full-blown PID system.)
I know of at least one regular poster here who's company plans to bring
out a similar typer of product. But I'll let him announce it publicly. I
see it's not yet mentioned on his web site.
Just saw your post and thought you might use some info.
I used the same setup you described, and have code examples, PS/2 spec.,
electronic interface, mechanical setup etc. on my web pages at
Did both PS/2 and RS232 mice, and it worked great.
