There is a HighFrequencySampling demo app that might have some clues.
If you are using the TimerC component your minimum sample time will
be 1 millisec and you probably want to go faster than that. You can
free-run the ADC so that it takes about 10 clocks to do a conversion,
which will be about the fastest you can go.
Both of the above are left as exercises for the reader since I have
not done any of it and don't use the micasb board anyway. The controller
spec sheet can guide you in free-running the ADC.
I wasn't following along on the MicInterrupt thing. I don't see a
signal labeled that on the micasb schematic so I guess I can't be
of any help there either...

Hello,
I want to sample the microphone as fast as possible on the micasb
sensorboard (for a ranging application).
How can I do that?
When I use a Timer which fires each tick, it fails to detect the
sounder... (setting it at higher values yields in a large loss of
precision)
(I posted a question about MicInterrupt before on this mailing list
(concerning MicInterrupt that fires only once when my micaz nodes boot),
but I haven't been able to find a solution for it...)
greetings,
robin
