Abstract: Sensor electrodes are coupled, in a first configuration, to input channels of a processing system. The sensor electrodes are used to acquire a measurement of current. In a second configuration that is different from the first configuration, the sensor electrodes are coupled to the input channels. The sensor electrodes in the second configuration are used to acquire a capacitive resulting signal. Positional information is determined using the current measurement and the capacitive resulting signal.

Abstract: In a method of capacitive sensing, a first plurality of sensor electrodes of a sensor electrode pattern is coupled, in a first configuration, to input channels of a processing system. The sensor electrode pattern is associated with a sensing region. The first configuration of the first plurality sensor of electrodes is utilized to acquire a measurement of current. A noise environment is determined through analysis of the measurement of current. At least one subset of the first plurality of sensor electrodes is coupled, in a second configuration, to the input channels. The second configuration and the first configuration are different. The second configuration of the first plurality of sensor electrodes is utilized to acquire capacitive resulting signals.
