I think the easiest way to do this is for a point to point network or
even a network with a hub is to use raw ethernet packets. An ethernet
packet has a payload of up to 1500 bytes. That should be large enough
for most things we would want.
On top of the payload we have around 20 bytes of
We've had previous discussions about using ethernet for real time control.
In theory, this is NOT difficult stuff. I'll bet I could get something
going in a week or three.
In practice, though, it is a PITA. That's because you would need a real
time driver for each of the zillion or so different

The application of EMC2 to many and various projects (not just real
time) would lead to a clearing of the 'real time geek fog' surrounding
this type of project. We need to take the IFM button

I'll have to do some reading about it. But as far as I understood from

Why not control realtime stuff over ethernet? I stumbled upon this a

Gentlemen,
I think the idea of controlling everyday things with EMC2 is the
right thing to do. The more things controlled the better the
understanding. EMC2 is so versatile it can control and 'enhance'
almost any project. The more people using it the less geeky (if that
is a word) it is. I
