There's no "data rate" on these GPIO pins; you'd have to bitbang them.
Interfacing with a digital microphone won't work, as you can't ask
their binary states quick enough.
Honest recommendation: Use anything else to connect your microphone to
your PC – if you have a microphone for which an audio driver exists,
you can directly use it in GNU Radio via the Audio Source.
Best regards,
Marcus
