Problem with DT Inst Interrupt + NAP

[Demon]

Pas de problème.

Can you:
- have an external clock IC,
- save the time on memory,
- put PIC to sleep,
- wake up the PIC every once in a while using a 555 timer,
- check the time elapsed since sleep?

I'm sure there are simpler ways.

I'm not sure if ElapsedTimer supports it but the way to do it, I'd think, is to use the TMR1 oscillator and drive it with an external 32.768kHz clock crystal. That oscillator doesn't stop when the PIC is put to sleep.
