Hi,
I'm developing a gadget with a PIC18 and I would like to have the amount of charge that is left on the battery(LI-ion) that is charging it. My initial thought was to use the ADC to measure the battery's voltage, but since the ADC uses that same voltage as reference it wouldn't work at all. How is charge measured in a battery normally?
Thank you
