I am trying to attach a hardware interrupt on pin 0 from core 0 of esp32 in dual core mode but this doesn't work at all (no response at all and no errors) and moreover attaching the interrupt in setup function (which i assume runs on core 1) does work but esp32 reboots with guru meditation error.
Heres my code

I have implemented this on arduino uno and pro mini but now i want to shift to ESP32.
I want to detect zero crossing and do phase cutting stuff on core 0 and make core 1(normal loop function) do all other stuff.
One more question please tell on which core does network calls get executed, I dont want to disturb core 0 (zero crossing stuff) atall.
As you can infer from my libraries I want to start a webserver also.
Thank you everyone in advance
