Hello All,

we (at CTU have invested
significant amount of work to the CAN and CANopen work.

We have almost fully rewritten original Arnaud's Westenberg driver
in the frame of the OCERA project. It has been marked as LinCAN.
It supports Linux and RT-Linux now and has more not so commonly
implemented features.

FreshMeat LinCAN entry

OCERA ( - Communication components

Some short quick start info on my page

Latest PDF doc with internals, history, other CAN drivers evaluation

One of our department projects utilizing LinCAN and Presentation

We and I personally have plan to port it into RTEMS environment
in the longer time frame. The advantage is, that driver supports
more chips and intelligent CAN controllers by now. The support of more
than 20 individual cards is result of this generic approach.

People from some companies are cooperating on Linux version
already. We would be pleased to find more people who would
like to cooperate with us. We would like to hear your comments
as well.

We have focused on CANopen by now but automotive CAN applications
and infrastructure is interresting for us as well.
We have monitoring tools and even Skoda Octavia car for automotive
CAN teaching and testing at our department. We have even played
with Osek there on the self-build HC12 based boards.

Best wishes
