Can your implementation watchdog.py component be used for esp32?

kevinkk525 commented 4 years ago

Well it should work. But there is actually no point in using it with the esp32 because it is a software watchdog implementation using Timers. It was useful on the esp8266 due to a bug in the micropython firmware which has been fixed a long time ago. I don't think I've ever seen an esp8266 be reset by the watchdog since then but I kept it, just to be sure. The esp32 has a hardware watchdog and I've seen that one resetting my boards occasionally so I don't think there's any benefit in using an additional software watchdog on the esp32.
