Electret microphone to ADC
I'm new in PSoC family.
I am working at connecting microphone to PSoC but with no effects. I understand that I need a pre-amplifier but I wonder if it possible to use embedded software amplifier? I think about PGA or Opamp. I use them but I can't see any signal (except microphone power voltage). I use voltage divider to power the microphone.
