Abstract
A method calculates a correction factor for one or more of capacitance sensors and generates a current from a mutual capacitance of one of the capacitance sensors. The method applies the correction factor to the generated current to generate a corrected current and converts the corrected current to a digital value. The method determines a position of one or more conductive objects in proximity to the one or more capacitance sensors based on the digital value.
