Sleep & nap

[keymuu]

Just curious if you were using a USB development board.

Did you get it working?

Yep ... it works THANK YOU Bruce

Both SLEEP and NAP work on 18F4550 !!!! at least on my PIC18F4550 !

The fault was in the bootloader: WDTPS was too big, 128 is ok

Thank you all for your help !

Would a USB development board be good for... what?
