In one embodiment, a method includes controlling a touch sensor of a device. The control of the touch sensor includes a first processing cycle executed by the controller that comprises acquisition of touch-sensor signals from the touch sensor; a second processing cycle executed by the controller that comprises pre-processing of the touch-sensor signals; and a third processing cycle executed by the controller that comprises processing of the touch-sensor signals to determine whether a touch or proximity input has occurred with respect to the touch sensor. If the touch or proximity input has occurred with respect to the touch sensor, a location of the touch or proximity input is determined. The method also includes controlling other sensors of the device. The control of the other sensors includes one or more fourth processing cycles executed by the controller concurrently with the first processing cycle or the second processing cycle.
