Abstract
An apparatus (40) and method (700) provide power-efficient reading of a touch sensor (10) by performing transform-based reading of the touch sensor (10) according to a read configuration (80) that accounts for touch-surface areas that are indicated as touch targets (68) for receiving touch input. Advantages such as power savings and more robust touch detection flow from the intelligent selection of which sensing lines (14) of the touch sensor (10) to excite and which excitation frequencies (52) to use for exciting them.
