Anyone says how the s3c6410 use the energy by the lithium battery, because i´m using one ci that charge the battery of the lithium and i want take in the screen status of battery, percentage of the charge. If you can help me , thank you.
Maybe with the ADC?
how Ferite?
Put the voltage from the batteries to a voltage divider. Take the samples from de divider to the board's ADC. You could determine what is the maximum voltage when the battery is fully charged and the minimum when they are full discharge. Having the extremes you could calculate where is the voltge in a given moment. It wont be very accurate since the charge/discharge of the LiIon batteries are not linear, but it would give your users an aproximation.
