Ron, As you see, ( and probably test on your skin) a half from the people of this planet try to protect something and the other half are trying to find what the first half has done... It's crazy ! Maybe you was to angry today, but what if someone read your code, what's so big deal ?... what if he/she made a clone of your product, ( which could be better than yours, you must admit this...) It's not the end of your life... The best method to protect your firmware is to put the source code on your web page...then no one will attempt to read your pic. [ smile on your face ? ] Cheers, Vasile -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
