Does it have to be PCI?

I think people here have a CANBUS-to-USB
adapter running under QNX.

Would that do what you want?  You don't have
to write any software to make that work, just
get the canbus-to-usb adapter, which I don't
think was very expensive..

Re: RE: about CAN card driver   
Yes
I want to use the PCI CAN Card

if anyone have the PCI CAN Card driver that good 

Our system cannot use the CAN-USB adopter, because it is not real-time, and communicate with the other device by USB, I 
think it is not a  good idea.

thank you!

ok, it was worth a shot - CANBUS isn't exactly
high-bandwidth  :)

I would recommend seeing what documentation
(registers etc) you can dig up, and perhaps 
a sample source driver for another OS for this 
card.

Then, look at how memory is mapped in QNX, and
interrupts are handled - both ridiculously easy,
look at any QNX driver source on the foundry - 
and that's probably about all you need.

RE: RE: about CAN card driver   
thank you! I found a card from steinhoff company.
so I donnot need to develop the driver.
 
the next step, I must learn to how to use it.
