I have read in this thread: Problem measuring currents with ADC that someone else had a similar problem, but my main concern is not the noise, but the offset.
I have seen that you were working on how to calibrate the ADC pins, is there any advance on that topic?
I am using a 0.05ohm resistor, because I need to measure amperes, I do not know if it is feasible to measure the sleep current while I am trying to measure high currents.
I am using the ADC method because the system is powered with a battery, is there another method to measure the current? I have thought about using SENSE because it can be calibrated, any tip?
