[Tinyos-help] Regarding MTS310 and MIB510 microphone sampling

[Akankshu Dhawan]

Hi All
I have been trying to get microphone data from MTS310CB sensorboard on a
MICA2 (MPR400) .
I am using an MIB510 gateway.

Using the XMTS310CB application:  I am getting a 1 sample for every 1 second
and sometimes even 1 samples for 2 seconds. This is not desirable for my
work. I tried changing the timer rate but it did not change the
characteristic much.

I tried the Lesson_4 which comes with the crossbow's moteworks setup for
sensing light. That setup could sense light upto 5 times a second which I
found encouraging and changed photo part of the code to the code in XMTS310
(just microphone sections) . I am getting 4-5 samples of microphones but
they seem to be showing random values and not responding to the surrounding
sounds.

Could someone guide me how to get atleast 10-100 samples per second using
this hardware ?
Or suggest another hardware/sensor that can provide me a good audio sampling
rate. Also just for reference, I am using Moteworks by crossbow.

I would really appreciate any help.

Thanks a lot.
