HI, All

Who uses an external watchdog solutions for MCU boards (for very important projects)?
Any recommendation what a ready-to-use board you use ?
For me best solution, i guess, just reset impulse generator, 1 minute period.

Yes, i have asked indeed for real examples, maybe ready board to order.
But found the chips named like "supervisor".

But the main reason of hangs was anyway in the code, if more sharp - the stack size not enough.

a way to avoid stack issue is to make string operations in dedicated small sub each time it is needed because at end of sub, all array and string are released on stack.

HTTP JSON requests can be rather huge, and if there are several such requests - it's lots of subs calling each other... And any adding to JSON may lead again to trouble.

A microcontroller is not useful for such a task, sorry
No, modern controllers are good, and able to do it (ESP family at least). Yes, not convenient, but it works :). For me.
RAM allows to make all these. Just to make correct code structure.
