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.
