Subject: [Xenomai-help] Waiting w/o burning CPU

Message-ID: <4B1F9E26.7070900@domain.hid> (raw)
Hi,
Could anyone tell me which Xenomai function should I use to wait (even
up to 100msecs) without burning CPU. I tried using nanosleep() but it
was always returning with 1 (one) and analyzing my output pins with an
oscilloscope I couldn't see any time delays. Now I use rt_timer_spin()
but I'm not sure whether I'm doing any wrong to my rt threads (or anyone
else in the kernel). My environment: a kernel driver with lots of rt
threads controlling stepper motors. The function where I want to wait is
a work_struct task (called by a schedule_work). Thanks.
