#115572 - Hallo?
Responding to: ???'s previous message
Rucha said:
you said that the watchdog can even hang but i guess the basic function of wdt is to prevent abrupt functioning of the controller

Have you understood, what I wrote in my last reply? That the hang-up condition cannot be terminated by a simple reset in many cases, but only by a power-down and power-up again?

You should really find a way, that the ESD-events will no longer make your micro to hang-up. Don't expect the watchdog to solve this. You need to change your hardware, your layout, your grounding management, or whatever you have designed wrong!!!

Rucha said:
Anyway, do you think that maybe an external watchdog would

Solve your hardware problem!

Show us your layout and wiring scheme. Maybe we can find the mistake.
