True, but the sensor returns the value as a signed integer in C. That is where the earlier negative number problem was, it would have to do yet another conversion to go to Kelvin, and it would be just one more potential for error. Everyone knows that a bad conversion doomed at least one space craft, let's stick to Centigrade. > Alternatively, centikelvins would fit nicely in 16 bits if anyone cares... > > 655.35 K = 382.20 ?C = 719.96 ?F The range for the sensor is -55 to 125 C, if an application didn't care about precision they could store it in a signed 8 bit value just fine. -- David Fries <[EMAIL PROTECTED]> http://fries.net/~david/ (PGP encryption key available) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
