Hardware Watchdog

Postby cruzinchris » Sun Apr 19, 2020 9:02 pm

I am working on a mission critical ESP32 and I wish to incorporate a Hardware Watchdog. Since there is no Reset Pin on the ESP32, how would I do that?

Thanks in advance.

The EN line works as a reset pin. Pull it low, ESP32 resets. Pull it high, ESP32 restarts operation.

Wow,, that was simple. Thank you. See what happens when you let a hardware/analog guy around the ESP32!
