Mcpwm Flickering

[markiv]

I am trying to make a ac dimmer using esp32 via mcpwm .
I have used 4n35 to get zero crossing using it as sync and via phase dimmer i am able to dim the lights but there is lot of flickering .
What can i do ? any suggestion is it the fault in esp32? beacause i have tried it with Mega and its working flawless

Have you tried looking at the signal with an oscilloscope?
