There are timing problems when a timer is below 4 ms - I
believe it was due to the microcontroller not being able
to keep up with executing code that quickly. If you look
at the code that gets executed when you call
Timer.start(..), one of the first tests is to make sure
you're not trying to start a repeating timer that is at or
below 3 ms.

I am using Tinyos-1.x with a MicaZ mote and trying to do
some work at high rates. But when I use the TimerC, it
seems that the timer couldn't work when the interval is
below 4 milli second. It means that when I use codes as
follows,
command result_t StdControl.start() {
// Start a repeating timer that fires every 1000ms
return call Timer.start(TIMER_REPEAT, 1);
}
Then the timer didn't work. The event of Timer.fired()
couldn't be triggered. So why this happen? Is it because
the precision of the timer of micaz?
Thanks a lot.
