I'm trying to make msp430f5529 launchpad read audio signal from microphones. I'm testing these two mics: 1) https://www.sparkfun.com/products/9868 2) https://www.adafruit.com/products/2716 When I test the mic signal on scope, it is alright. However when I connect the signal to ADC12, it only tells me the input is a DC-like signal, almost constant value no matter how the audio signal changes. Is there bench code to test ADC12? Or something is wrong with the impedance? Any help will be appreciated! Thanks guys. Liang
