[En-Nut-Discussion] NutSleep(0) doesn't yield

[Harald Kipp]

That's how it's designed. As NutSleep(0) waits for nothing, the
thread continues to run, if it got the highest priority. But note,
that some background system threads like the Ethernet receiver
(if registered) run at very high priorities.

I assume, that the granularity of 1ms is too high for your
application. Then you should consider implementing hardware
timer interrupts.
