That call sets the ADC clock pre-scaler and changes the amount of
time needed for a single conversion. The 'rate' argument can be
from 0-8 where 8 is the slowest (if memory and my code comments
serve...). When set to 0 there is no pre-scaling and the conversion
takes about 15 clock cycles, at 8 the conversion takes something
like .3 milli-sec (again relying on my own memory devices).
Look up the ADC stuff in the controller spec-book for details.

Dear Sir
I saw your contribution on the TinyOS website, I have the problem of
using the interface ADCControl.
I will be gratefull if you could help me in this.
I tried to use the command SetSamplingRate, but I had problems using it?
could you please explain to me how to use it.
and also I didnot understand the argument "rate", and still I dont know
the resultant sampling rate at each value of rate
your help is highly appreciated
