<p>In various aspects a host processor and a touchscreen controller may concurrently process a signal sent by a touch transducer when a touch is detected. A touch signal sent directly from a touch transducer may be formatted into a calibrated touch signal that the host processor can process. The calibrated touch signal may allow the host processor to receive and process touch signals from transducers and touchscreens from various manufacturers. The touchscreen controller and the host processor may each independently assess the touchprocessing state. The touch-processing state may be set to one of a plurality of "states," and the plurality of states may have rules for transitioning between the states. In various aspects, a host processor and a touchscreen controller may dynamically set, among other things, the scanning rate and resolution of a touchscreen panel based on the touch-processing state.</p> |
