i have write a code for 16f876 for reading a temperature from a lm35cz.
Now i must subtract a vref of 2,5 volt from ad conversion result:

ADCIN 0,AD_Raw       Place the conversion of channel0 into AD_RAW
AD_Result=(AD_Raw*10) */ Quanta      ' Quantasize the result

where Quanta is 1250 (source from EXPERIMENTING WITH THE PICBASIC PRO COMPILER).

Now i have try to subtract from AD_Raw the number 25000 (2,5 volt) but it not work correctly.
which number I must subtract from AD_Raw???
(2,5 volt is my ref voltage for negative mesure)
