I am only "listening" the conversation for learning a bit about
xenomai usage and I am no CAN expert, but
I think your implicit comparison is not fair.
You seem to compare CAN usage under VxWorks on hardware
which may be far away from your laptop + parallel port CAN I/F
with Xenomai don't you ?
Am I ? It was running on a PC 486 but indeed with a PCI based CAN
adaptor. And I am not saying it was any better, only that I was not
aware of any latency problems. Who knows, maybe this problem is
inherent to CAN via sja chip on PC's?
By the way I understand that your conclusion may be that
using Parport CAN I/F on Xenomai Laptop does not fit your need.
Are you telling me this? Or asking? I have not drawn any conclusions
yet. Don't know enough about the driver to be able to tell. This
"bottom half" thread matter sounds rather interesting. ;-)
