 		 #174038 - feed the dog
Responding to: ???'s previous message

If your code can get stuck in a sequence that includes "kicking the dog" then, clearly, the Watchdog cannot get you out of that!


It's right that I must restart the watchdog in many functions.
It's a shame because I'll prefer to do that only one time on the main loop of my soft.
But I don't know solution to extend watchdog timer longer than 500ms...

So, in conclusion I'll re-re-re check my soft in order to find a possible infinite loop feeding the watchdog.

It's pretty good ! Thanks to all your posts, I've got some clue to solve my problem.

Thanks to Andy Neil, Richard Erlacher and Kai Klaas for your help.

I check all theses points and I come back soon to gives you some results.

Thanks !
