Functions have changed. Maybe wait for the update guide to come out?

@frdoni LEDC functions have changed, migration guide and documentation is almost ready.
For esp_random() function you need add an include #include "esp_random.h".

I am closing this as there won't be any action needed.

Where can I find it? I'm getting ledc errors all over the place.

@frdoni another option to check LEDC API docs source file or reworked examples.

Thanks, @P-R-O-C-H-Y. I figured it out by looking at the new AnalogOut LEDC examples 👍🏼
