hi, in library `bradzilla84/sleepydog` the two nodes have the watchdog implementation, start them with the INIT pin. ---

I thing I understand know… I use the first one for reset. I conect the INT with a node to prevent pulses a timer for example and if the controller stucks the watchdog do the job and reset . right? ---

It is correct, if it does not receive a pulse that could be used `continuous-pausable` if a false one arrives, the micro resets after 4 seconds or the established time ---

To clarify something else, the pulse can not only be internal, it can also be the signal from an external sensor. ---
