Is this one still relevant or does somebody already have a newer version of this overview?It doesn't include the Hardware Abstraction Layer, so from the point of view if what you are attempting to do (which would almost certainly be a realtime HAL component) that diagram is almost no help at all.
Ok, then then we probably have to figure out where the best places for our adoptions are. But quite sure, somewhere in HAL, as you told.
This page: http://linuxcnc.org/docs/html/hal_basic_hal.html Might be useful. You would probably be writing a module like those described near the end of that section. You might want to do it in comp: http://linuxcnc.org/docs/html/hal_comp.html But it is possible that comp might be too limited for your application.
I'll take a look at this one. It seems quite interessting. Thanks for the tip.
This device: http://www.poscope.com/product.php?pid=27 might be a useful development "mule"
Well, forgot to tell, that we are using an industrial PC with sercos and other fieldbus interfaces onboard. So Hardware shouldn't be a problem.
