V = ADCresult * Vref / 1023

I am using an 18F2431 with 10 bit ADC in a barometric altimeter, but with a bit of extra code, I get 16 bit resolution..
How?

How?
Ignoring all the variables and stuff, basically you just sample the 10 bit ADC 64 times, adding all the sample values into a variable, and voila, 16bit result!!
Using 10 bit accuracy, I am limited to 5 foot resolution, but with 16 bits, I get 9 inch resolution!!!
hi shax,
I cant see any point in increasing the resolution to 16 bit when the accuracy remains at 10bit.
It is possible to sqeeze an extra bit from 10bit by oversampling.
My suggestion would be to use a £1GBP, ADS1100 16bit ADC piggy backed on the top of the PIC and connect using I2C.
