[maemo-developers] precision of ADC value of battery

[From: Vinod Hegde]

Hi,

I read dev/retu (using ioctl) to get the voltage value ( ? ) of battery.
RETU_IOCH_ADC_READ is the argument for the ioctl. I repeatedly ran the
application which reads and prints the value. but it does not vary much
unless i run heavy application which consumes lot of power. I want to see
the minute changes in the voltage level ( probably the change in the voltage
level after 20 milliseconds). How do I get a better precision. Is it that
the returned value is the one with highest precision.?..

Thanks for any help...
