Hello all, Please, anybody knows the diferences between PIC16F87X and PIC16F87XA? I buy the new version (XA) and the ISP don't work fine. I don't found in MICROCHIP application notes (39591a.pdf) detailed information about it. Please, help me! Thanks all in advance, Eduardo Garcia -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
