Hi,
Now that I've had help with the WDT, the other issue is the minimisation of the running current when the device is awake. I have an 18F26J53 on a bit of strip board with a couple of LEDs. When sleeping, my 'cheap' multimeter reads 0.03 mA (nice!), but when not sleeping, but simply in a pause for 3 seconds, it's drawing just over 10 mA! The LEDs are not powered on, as far as I can tell, I've powered down all the possible internal modules with PMDIS0-3, switched ports to digital and set all low.
What is drawing 10 mA?!!!
If I can resolve this I'm onto a winner!
Best regards to all fellow PBP'ers!
Cheers
