Abstract
A method includes obtaining, by a processing module interacting with a touch screen of a computing device, self and mutual capacitance data from a plurality of drive-sense circuits of the computing device. The method further includes generating, by the processing module, capacitance grid data based on the self and mutual capacitance data. The method further includes determining, by the processing module, a use for the capacitance grid data. The method further includes determining, by the processing module, data requirements for the capacitance grid data based on the use and properties of the capacitance grid. When data reduction is enabled, the method further includes determining, by the processing module, a data reduction scheme based on the data requirements and an output data rate. The method further includes processing, by the processing module, the capacitance grid data in accordance with the data reduction scheme to produce reduced capacitive grid data.
