Subject: [Xenomai-help] Calling comedi from a RT task
Date: Tue, 02 Dec 2008 09:01:27 +0100 [thread overview]
Message-ID: <4934EB57.9080305@domain.hid> (raw)
Hi,
I am using Xenomai 2.3.1 and comedi with driver "ni_pcimio". I am able
to create a RT task that triggers each msec. But calling the comedi API
kicks me out of RT as indicated by /proc/xenomai/stat (column MSW). The
modules loaded are:
comedi_fc 3584 1 ni_pcimio
kcomedilib 20868 0
comedi 33248 6 ni_pcimio, ni_tio, comedi_fc, mite, 8255, kcomedilib
licModule 44272 1 kcomedilib
The comedi modules are from a 2.6.20-14-ipipe/comedi/driver directory.
How do I use the comedi API so that the task will stay realtime? What do
I have to check?
