Hello,

I'm working on a leading edge dimmer, there for i would like to use the MCPWM functionality of the ESP32.
But i'm a bit stuck.

This is what i have so far:

#define GPIO_PWM0A_OUT 0
#define GPIO_PWM0B_OUT 0
#define GPIO_PWM1A_OUT 0
#define GPIO_PWM1B_OUT 0
#define GPIO_PWM2A_OUT 0 ...

Hi,

Have you looked at MCPWM, i'm using it for a AC Dimmer.
It works great, please keep in mind that if you use a optocoupler for synch use a dual schmitt trigger to get a stable signal.
i had some interupt errors.

I have a test setup to dim a light.
the hardware conssist of a ZCD connected to GPIO22
a vom1271 gate connected to GPIO23
The vom controlles 2 mosfets back to back.

i have the the code working, only the light is flickering and the pwm signal isn't stable.
what can i do to get a more stable pwm ...
