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 with ...

PWM with sync input
Hi,
I need (on ESP32) generate PWM signal (400Hz), this is fine but I need to sync this PWM to AC mains 50Hz (via optocoupler).
Can anyone point me how to do on ESP32/Arduino ? In old design (M2560) I have connected "sync" signal to INT pin and just reset/restart Timer what generates PWM on each ...
