DeviceNet and ASi stack recommendations.

Just for my interest. Who is implementing DeviceNet these days, in 2013? And the Intel 82527 is the oldest CAN chip on the market, even not anymorre available at Intel. Are you going to use one of the established Linux CAN drivers for it?

Regards Heinz-Jürgen oertel

The Intel 82527 is quite usable for simple peer-to-peer CAN bus applications as well as CanOpen/DeviceNet slaves.

Since you are referring to Linux 2.6, I guess you are planning to use CanOpen master / DeviceNet scanner, for that, SJA1000 from Philips in Pelican mode would be a much more appropriate alternative.

While in the old days, ordinary RS485 tri-state drivers were used for CAN bus communication, but what does RS485 and UART have to do in this context ?

ASi is more important than DeviceNet.

We have our reasons :)

That's not a problem in this case.

Possibly. There is a CAN driver now for J1939 that's adequate.
