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...
