[Xenomai-help] real-time ethernet

[Roland Tollenaar]

Hi,

Again a bit of advice required. I have the choice of interacting with a 
remoteIO station via ethernet or CAN as well. I need CAN anyway for the 
sensor but I suspect that communicating with the remote IO station via 
ethernet might be substantially easier programming than doing this with 
CANOpen.

Can anyone confirm this? Does anyone with experience in both prefer one 
or the other?

And what can be said about this and xenomai? Would I use the standard 
sys/socket library or is there a real-time xenomai implementation of the 
same functionality?

Kind regards again,

Roland.

Check

http://www.rtnet.org
http://www.xenomai.org/index.php/RTnet:Main.

If it is simple to set up? Well, I'm probably the wrong person to ask...

Hi,

Thanks. I think I will stick to CAN. I hope I achieve the speed.

Could you possibly look at my tsc issue and give your opinion please? I 
am actually desperately waiting for someone to comment on that and 
obviously hoping that there are no severe problems to be expected if I 
run the user part built with;

--disable-tsc

and the kernel in 486 processor family.


Regards,

Roland.
