Hi everyone, When I set an alarm at d0 to fire dt microseconds later, it quite often fires by tens or hundreds of microseconds earlier than *d0 + dt* (based on Alarm.fired() event). My understanding is that the underlying interrupt will be generated at (d0 + dt). But because of ISR handling delay, fired() event should be signaled no later than *d0 + dt*. So the above phenomena should not occur. Can anyone please give me a hint?
