Using the 16F628 instead now, I had tested for a day at a simulated ~1000= MPH,=20 and it worked well, and I've also run it for a day at ~1600MPH ! In both= =20 cases, it works well, with the EEPROM saving the 0.1-mile distances relia= bly. =20 I've logged 60,000+ simulated miles already. So the write time is more t= han=20 fast enough for my original intention of supporting speeds up to 250mph. = :-) Thanks, -Neil. -- http://www.piclist.com hint: The PICList is archived three different ways.
