A jiffy is one tick of a 32khz clock, or about 30.5us. Boomerang is compatible with the top layers TinyOS 1.x. We've kept the lower layers as similar as possible, but there may be some changes you'd need to adapt to.

Thanks for a prompt reply, can i port my application written in 1.x to boomerang directly , because I 'm afraid i have already done too much of work and it will be late if i have to make too many changes. Is there any work around. I'm presently trying to work on a copy of the timerjiffyasyncC. I have changed the timer from B4 to B5 ( i think B5 is free). But I'm not clear as to what jiffy value to use in the Timerjiffyasync.setoneshot(jiffy) in order to sample at 3Khz. regards jagan On 5/11/06, Cory Sharp <[EMAIL PROTECTED]> wrote: > If you are trying to sample at 3khz, you should use a hardware timer > instead of a virtualized timer in TimerJiffy or TimerMilli.
