AtomS3U microphone

[viotemp1]

Hello,

I'm trying to use this component with AtomS3U - SPM1423, but this has only MIC_CLK & MIC_DATA pins. Any ideea what to do with the ws_pin? It looks like it's mandatory.

I tried also this external mic (based on the same chip) - pdm - the same, the WS pin is missing.

Regards, V

Hi!

Unfortunately, PDM mics currently are not supported, there was an attempt to support them, you can read previous discussion and you can also check out branch https://github.com/stas-sl/esphome-sound-level-meter/tree/pdm_support, but seems like there are still some issues, I just can’t try it myself as I don’t have those mics.

Hello,

I tried that branch and I get sound_level: 118.52 all the time. MAybe you can find some hints in M5Stack PDM I'll check more into the source code. Thanks!

[viotemp1]

I made a fork and changed a bit fork according to the M5Stack PDM example. It's working now, not sure about the values ranges and calibration, but I do not need that.

Thanks for help!

@viotemp1 can you share your config on how you got it working? I'm trying to get an Atom Echo to work as a sound level meter too, and it also uses a pdm mic.
