For the 2nd demo, I only treat the PIR sensor as external interrupt, here is the source code:<br /><a href="http://www.bitartist.org/2008/12/avr-in-sleep-mode-power-saving-mode.html" rel="nofollow">http://www.bitartist.org/2008/12/avr-in-sleep-mode-power-saving-mode.html&quot;</a>Bitartisthttp://www.blogger.com/profile/02017974538058851707noreply@blogger.comtag:blogger.com,1999:blog-5981142976661648009.post-10738043727497872962009-08-27T23:34:01.577-07:002009-08-27T23:34:01.577-07:00yeah man this seems to be good...but where is the code to make this work???thanksOmar Carpiohttp://www.blogger.com/profile/18233359324734869339noreply@blogger.com
