[Tinyos-help] for problem

[Akankshu Dhawan]

Hi Michael
I have been able to get the Oscilloscope application working using the
DemoSensor. I now wanted to use the microphone onboard the MICA2 mote (I
have an MTS310CB sensorboard on top of the MICA 2 mote) .

I wanted to know the wiring conventions for the microphone component for
tinyos-2.x so that I can control the gain as well as sampling rate.

Regards
Akankshu Dhawan
