I'd love to see some good data on component aging. I've heard that components age; but other than opto stuff and aluminum electrolytic caps I've never encountered it--one payback, perhaps, from designing very conservatively. Other than EEPROM write endurance, do PICs age in any significant way? Dave D. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
