Summary:Embodiments include a method, input device, and processing system for driving a plurality of sensor electrodes for capacitive sensing. The method includes acquiring a first capacitive partial profile by driving a capacitive sensing signal onto a first sensor electrode of a first plurality of sensor electrodes while driving a second sensor electrode of the first plurality of sensor electrodes with a substantially constant voltage. The method further includes acquiring a second capacitive partial profile by driving the capacitive sensing signal onto the second sensor electrode while driving the first sensor electrode with the substantially constant voltage, and determining a first capacitive profile based on at least the acquired first and second capacitive partial profiles.
