Subject: How to talk to DAQ Hardware?
Date: Sat, 25 Aug 2007 08:45:05 -0700 (PDT)	[thread overview]
Message-ID: <154208.12082.qm@web36102.mail.mud.yahoo.com> (raw)

Hi,


I'm coming from the RTAI and RTLinux world and I just learned about the great
strides you guys have made in hard RT.  Anyway, I was wondering -- currently
how would one go about talking to DAQ hardware using the RT_PREEMPT patch(es)?
Will this "just work" with COMEDI?  What happens when a userspace hard rt app
calls into a kernel device driver in the simple case of an inb() or outb()
instruction?

I am hoping I can use this patch to do some basic input/output from a data
acquisition card that is driver by COMEDI -- using just synchronous acquisition
and output (basically writing to registers on the card, etc.. no IRQ's).

Will this work?

Thanks..

PS: I also posted on the comedi mailing list but wanted to ask you guys too.

Thanks again,

-Calin
