Changing PDM sound output pin

Post by karlkloss »

There's now an option to freely configure the I2S output pin, but how do I configure the PDM sound output pin?
I have a board where filter and amplifier are on GPIO3, so how do i change it from the default 25 and 26?

The PDM output, for the ESP32 classic, is always on the same 25 and 26 pins and I think that cannot be changed

In this case the output is mono on the pin I2S_DOUT_pin

That's what I wanted to hear :) .

Any chance that you can add the various new options around the sound output to the documentation?
