Multiple watchdogs?

[dizcza]

In a multithreaded environment, I'd like to use one watchdog per thread. I do not understand whether I can just spawn multiple instances of the IWatchdogClass, begin and feed them separately. The implementation, from the first glance, works with a single timer.

Hi,
There is only one IWDG so no need to implement several instance.

Well, that means I cannot control more than one task... All right, thanks for the info.

Please also add the stop function to the watchdog.

Well I think you don't know the IWDG feature, when the IWDG is started it can't be stopped except by a reset.

@fpistm what is the problem of stopping the timer?

I've read your link.

For instance, I can easily subscribe any number of tasks to a watchdog in ESP32. And I can remove/unsubscribe the task. IWDG is based on timer, and I don't understand why the user cannot simply stop it.
