Hi,
I have a problem with ADC reading of humidity:
Supply voltage
ADC reading
calibadc10/Nref
Caocul. supply voltage
------------------------------------------------------------------------------
4.5 877 230 4.56
3.0 822 324 3.23
Supply voltage: As set on the wall ward
ADC reading: readadc10
Nref: as given by calibadc10/debu
Calcul. supply voltage: Vpsu = 1048/Nref
Should'nt I be able to convert 822 to (something close to) 877 from these figures? Or have I misunderstood things?
I have checked internet, but there seems to be so many other problems involved in the questions and answers.
best regards
torben
