I *think* it is actually 0.0625 (1/16 deg C) IIRC it is 12 bits for -55 to +128, represented by a signed char=20 followed by 4-bits fraction. The number of bits accuracy is adjustable between 8 up to 12 if you=20 don't need the higher resolution. The tradeoff is quicker sampling time (up to 750ms for 12-bit IIRC) --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
