Hi Robert, Thanks for your response -- I appreciate your time. Ok, I misunderstood you. I thought you personally had seen two *different* versions of app note AN734. This thread piqued my interest and I wanted to see both versions for myself to see what corrections were made. I archive most data sheets I download for future reference. Thanks for the clarification and I'm glad your project is working. I'm all set on this. Best regards and take care, Ken Pergola -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
