P1 Pin Mapping & Interrupts

Hey Everyone,

We’re looking at adding a Watchdog, and I require an interrupt-able pin on my P1 to receive a nudge from the Watchdog, which I can then respond back to on a separate GPIO pin to say “don’t worry, I’m here”.

I’ve been trying to find a good P1 pin to attach this Watchdog to, but I cannot find a table that maps the pins, the identifies whether a pin is a) interruptible and b) whether the pin can be used in conjunction with other pins when it is tied to an interrupt.

I’ve dug around and can’t find the doc that would have this detail in.

Any pointers?



Have you taken a look at this page?

This discussion will also apply to the P1
