I've been messing around with PWM for audio on the original ESP32.

Now updated to output on several PWM channels, because why not? :)

Still a fixed frequency though - i.e. no IO control - this is still just me messing around.

And now with some simple analog control and the option to feedback back one wave into another for some basic frequency modulation.

@xorgrox I've been really surprised with the possibilities I must admit :)

I know I'm late to the ESP32 party!

@diyelectromusic It's never too late to start doing something like that. Some people are still tweaking comodore64 (which I find quite impressive) :D Many thanks for sharing this. I planning to use your materials in my small project. At first free drawing lfo with external clock sync!
