MicroPython
using the WatchDog Timer (WDT) #9322

As a possible way to protect valuable hardware against a continued power-on situation, I am looking at the WDT. The use is simple and effective. Out of interest and on the same topic, there is no mechanism to read the time remaining in the current WDT setting ? |

The WDT() mechanism varies somewhat between the ports. While to enable it with a certain alarm time, some allow to change the alarm time while operating. But that is hardware dependent. |

Thx for very quick reply. Am using Pico's, so rp2040's and played with it using MicroPython v1.19.1. Changing the WDT time is an option, but being assured the "feed" essentially resets it to the initial time-out is also fine. |

Yes, feed resets the WDT to the initial time period. |

Which device do you use?
