WDT help for Raspberry Pico

[bzisl]

Hi! I'm trying to use the WDT to allow a reboot in case of firmware hang, but there is no examples, or the doc is not available.
Which header we myst include?
Can someone help?

Thanks in advance.

There's a 50 minute lecture on the subject, by Van Hunter Adams. I haven't watched it yet, but they're always worth watching. He's made a whole series on the Pico, in recent times:

https://arduino-pico.readthedocs.io/en/latest/rp2040.html#hardware-watchdog has the built in calls. Note that the doc needs a minor ediot, the parameter really is milliseconds, not microseconds. You can also use the SDK functions bare with #include "hardware/watchdog.h"
