I set TSCON＝0x01、ADCCP＝10000 and got ADCDAT[27:16]=0x79E
According to the tempearture calculation in datasheet, the temperature is around -44degree celcius.
what is wrong with my temperature measurement and calculation?
You need to do two ADC conversion and average the values before plugging the voltage equivalent to the formula.
ADCCON should also be configured to 0x37A3
Why do we need to 'do two ADC conversion and average the values' before plugging the voltage equivalent to the formula?
This is because the chopping mode is enabled
