Abstract
Technology for an electronic circuit is described. The electronic circuit can include one or more timed general-purpose input/output (GPIO) pins and a controller. The controller can receive touch sensor data pulses from a plurality of touch sensor integrated circuits (ICs) that are each communicatively coupled to the electronic circuit. A first touch sensor data pulse received from a first touch sensor IC in the plurality of touch sensor ICs can be time synchronized with a second touch sensor data pulse received from a second touch sensor IC in the plurality of touch sensor ICs using the one or more timed GPIO pins. The controller can combine the touch sensor data pulses received time synchronously from each of the plurality of touch sensor ICs to produce joint touch sensor data. The controller can perform joint processing of the joint touch sensor data.
