i have tmotes.
i need to use an async timer that has tick (1/32768) resolution and it should fire accurately also. i think what i need is exactly what the CC2420RadioM uses as the BackoffTimerJiffy.

is one available?

i've been playing around with platform/telos/TimerJiffyAsync* but have not been successful.

i've made a copy of platform/telos/TimerJiffyAsync{C,M}.nc and simply changed the timer B4's to B5's.
my copy appears to run pretty well.

questions:
1) do the B4's and B5's interfere with each other?
1) any other precautions?

the async (periodic) timer interferes with the radio code (with sending fore sure and most likely receiving, too), so i have to stop the timer when the radio is sending and receiving.
thanks.
