Shouldn't get over 100C, though, I'd think. > Beware running PICs above 60degC. One problem I had was an A/D conversion with a PIC 12C672 took seconds above 60 degC, never figured out why, but a heatsink taking a power mosfet's heat away from the PIC fixed the problem. _____________________________ Lance Allen Technical Officer Uni of Auckland Psych Dept New Zealand www.psych.auckland.ac.nz _____________________________
