#83026 - Not generally a good idea Responding to: ???'s previous message |
Kick that watchdog within your interrupt This is generally not a good idea. OK, so I've just stripped Craig's comment of all context - but this is for anyone else who takes that comment out of context and thinks that kicking a watchdog from an ISR is generally a good thing. In general, it is not a good idea to kick your watchdog from an ISR. This is because it is quite possible for your "main" code to be stuck in some sort of infinite loop, while the interrupts are still all working fine and merrily kicking the dog - thus defeating the object of the watchdog! :-( |
