[Tinyos-help] Microphone data from MTS310CB and MIB510

[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.
