Over the weekend I looked over the 16 key serial keypad example at Bruce's website. I was wondering how would I go about adding a SLEEP or NAP command to his code if no button is pressed I could conserve power. And also how would I make it wake up when a button is pressed? After searching the forums I've seen the @sleep, sleep for X period but have not found a good suggestion for using SLEEP. Here is Bruce's link to the keypad code:
