Abstract
A method and system for detecting a presence of a conductive object proximate to a capacitive sense element during an initialization process of a touch-sensing device. A capacitance sensing circuit measures a reference capacitance of a reference sense element. A sensing parameter of the capacitance sensing circuit is iteratively adjusted to obtain a target measurement output value for the reference sense element. With the sensing parameter set to the sensing parameter value, the capacitance measurement circuit measures a first capacitance of a first sense element. A first capacitance difference value is determined between the first capacitance and a first baseline capacitance value for the first sense element. A presence of a conductive object is detected proximate to the first sense element when the first capacitance difference value exceeds a threshold value.
