Yes, we are talking about same CAN.
I do not let CAN use Ethernet. I just want it be used like Ethernet, in the
view point of I/O system. :)
Hello!
Are we discussing the same CAN protocol, as in Controller Area
Network, that Bosch invented mostly for its fuel injection hardware,
but then adopted by the car companies for managing the whole
vehicle,
and then adopted by individuals who build automation systems? if the
answer to all of that is yes, then it does not use Ethernet, that's
a
different protocol altogether.
As I recall it uses a collection of specialty hardware items, and
then
the RS422/RS423/RS485 wiring standards. Specialty hardware drivers
have been made for that. Intel makes a dandy device for that as well
which handles the basic protocol methods. You still need a good
processor for it, and of course an operating system, or atleast what
eCos does.
