Demo WDT - 看门狗例程

import time

# 不带回调的看门狗

# 初始化看门狗0
wdt0 = WDT(id=0, timeout=3000)
print('into', wdt0)
time.sleep(2)
print(time.ticks_ms())
# 1.test wdt feed
wdt0.feed()
time.sleep(2)
print(time.ticks_ms())
# 2.test wdt stop
wdt0.stop()
print('stop', wdt0)
# 3.wait wdt work
#while True:
    #print('idle', time.ticks_ms())
    #time.sleep(1)
