If you don't care about CPU utilization, busy-wait is the way to go.
Otherwise you can try to usleep() for something like 60-70 us (to lower the
CPU utilization), and then busy-wait for the rest of the interval (so that
you still have maximum precision).
You may want to have a look at this

sections 4.3 and 4.1.
