Watch Dog Timer

Example

Set the Watch Dog Timer to reset the device when the program abnormally fails to perform the feed operation at the expected time.

from m5stack import *
from m5ui import *
from uiflow import *
from machine import WDT
import time


setScreenColor(0x222222)

wdt = WDT(timeout=2000)
while True:
  wait(3000)
  wdt.feed()
  wait_ms(2)

API

wdt = WDT(timeout=2000)
  • Initialize Watch Dog Timer and set the timeout period
wdt.feed()
  • Repeat the feed operation within the timeout period to refresh, and reset the device if the timeout period is too long for the feed.
