when setup a small duty value(5% etc) , pwm waveshape become unstable every few second. how to solve this problem?
Dear Sashka,
I am using your library for driving RGB LED dimmer with SuperHouse esp-open-rtos.
I very much appreciate your work.
I want to share with you my last experience with it and I will be glad if it helps you fix the Frequency issue.
The good news is that if I am not using
multipwm_set_freq ()
to set it up, the actual PWM frequency is 1,2kHz. In any other case it stays at 100Hz or less, no matter what number I will choose.
It works very stable with this code:

I am curious if it is helpful, but an updated library by Espressif exists. I tried to implement it without success, but it may be useful for you:
