I don't know if this will work or not, I have not replied on this list
since it became consolidated. I have a PIC device using a 12C509 talking to
a 16 bit ADC. The way I convert to temperature is using a lookup table.
This was easier to implement then the math required for the Steinhart
equation. The table contains counts which correspond to the temperature in
one degree increments. Then I just do a linear interpolation for the values
in between down to 0.01 deg C resolution. Works great.
