Hello all. I have been working on an audio project with a PIC 16F877A, but it dawned on my today that I didn't think far enough ahead. I have a small mic that I am putting through a little audio amp, and that appears to work fine. My question is, how do I take the audio output (from the amp) and put it into the ADC? I know how to work the ADC, but the amp output is a voltage that centers around 0Vdc, so 1/2 the time it is a negative voltage (which I don't think I can put through the PIC's ADC). Can I add a DC couple to it to make the voltage center around some positive voltage (say 2.5Vdc)? There is probably a simple solution, but I haven't been able to come up with anything yet.
Thanks!
Thanks!
