from microcontroller import watchdog as w
from watchdog import WatchDogMode
import time

# Set a timeout of 5 seconds
w.timeout = 5
w.mode = WatchDogMode.RESET

# Increasing time.sleep(>5) causes a watchdog reset
while True:
    w.feed()
    time.sleep(2)

Looks good to me! Is there more you want to add?

[microdev1]

@tannewt Yes... I have to figure out a way to differentiate between RAISE & RESET modes in esp_task_wdt_isr_user_handler(void) which is called on watchdog interrupt.

Looks good to me! Thank you!
