Code looks reasonable to me. I say keep going. :-) Thanks! |

I think the CI failures are due to the code being compiled for boards that don't support it. I may be missing some guard macros. I'll take a look soon. |
…on boards that don't support PDMIn.

Okay adding guard macros has allowed the CI checks to pass. Should this be merged? I'm not sure what remains to be done. |

This PR adds basic PDM microphone support to the Espressif port. Only the most basic functionality has been tested: 16-bit, monophonic input seems to generate appropriate data when viewed in the Arduino plotter.
Support required adding implementations in
ports/espressif/common-hal/audiobusio/PDMIn.[c|h], as well as a change toshared-bindings/audiobusio/PDMIn.cto allow for clean deinit of underlying ESP-IDF objects.This PR is not intended to be complete, I just wanted to get it in front of more people to get feedback.
