Start at http://www.piclist.com. Hit the Beginners Checklist. There're links for some programmers. Read everything. Keep reading. Don't take side paths that distract you and prevent backtracking and cause you to get lost. :) PIC is one of the most heavily supported hardware topics on the net. It's -all- out there. Keep looking and you will eventually find somethig that explains things in a way you can understand. > Isp seems a cool feature, but do i have to "sacrify" pins? Check the list archives for the zero pin programmer. Check the archives early and often for common FAQ questions. Have a :) day! jb -- jim barchuk jb@jbarchuk.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
