Hi all Can anyone point me towards a resource for 16F877 in-circuit programming = by direct connection to a PC serial port, together with Windows 2000=20 compatible software? There seems to be alot of info regarding 16F84 ISP=20 but I'm unsure whether it's possible to use the same programming=20 software / interface circuitry with the 16F87X devices. Many thanks in advance. Stuart -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
