Any updates could we use mcpwm for dimming without flickering?

Hi,

after some experiments I was able to set PWM/SYNC with mcpwm in Arudino, seems this works fine but I also try to setup Capture mode, I follow example for mcpwm but I stuck on reading/setting registers, problem is with this lines:

static mcpwm_dev_t *MCPWM[2] = {&MCPWM0, &MCPWM1};
it end ...

//#include <stdio.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_system.h"
#include "esp_spi_flash.h"
#include "driver/gpio.h"
#include "mcpwm1.h"
#include "string.h"
#include "freertos/queue.h"
#include "esp_attr.h"
#include "soc/rtc.h"
#include "soc/mcpwm_reg.h ...

Have you tried looking at the signal with an oscilloscope?

no ihave not tried but i directly connected a bulb , but its flickering a lot

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 ...

Hey I am too trying to make a ac dimmer using mcpwm but their is lot of flickering !, I am using 4n35 optocoupler and getting a smooth wave .
