Subject: Re: Use SLEEP instruction for longer (?) runtime
From: Andrew Jamieson (andrew.jamieson_at_projectlab.net)
Date: 2003-01-22


Initial tests seem to indicate that it saves ~10mA off the average current
when sleep is set on (130mA avg -> 120mA when sleep on). Some of this
decrease will be due to red LED not being on all the time tho, but that is
probably only around 1mA, which may very well fall off the edge of my
testing resolution at the moment. More precise testing will have to wait
until I get home ...
