18F14K22 Wake from sleep
PostPosted: Mon Aug 08, 2011 9:04 pm     Reply with quote
Hi
I'm trying to use ext int 2 to wake from sleep (not idle). PIC docs seem to say this is possible, but I can only get it to work with IDLE, not sleep.

Anyone got this to work successfully?

Thanks!

1. Post your small, compilable test program and we'll look at it, and/or
test it in hardware. Compilable means that it can be copied and pasted
into an MPLAB project and it will compile without errors.

2. What is the external device that is causing the interrrupt ? What are
the voltages levels that it applies to the PIC's INT2 pin ? (High and low
levels).

3. What's the Vdd voltage of the PIC ?

4. Also post your compiler version.
