1. A system comprising:

  • a sensor configured to receive signals on conductive lines arrayed along a first axis and a second axis; and

    a controller configured to;

    trigger at a defined first time within a refresh cycle of the sensor, at least a portion of the conductive lines with a trigger signal and to sample output of the sensor based on the triggering to detect finger touch interaction;

    sample output of the sensor to detect a stylus signal transmitted by a stylus during the refresh cycle;

    detect a second time within the refresh cycle for sampling the sensor for the stylus signal; and

    sample output at the second time determined in subsequent refresh cycles to detect position of the stylus based on the stylus signal received by the sensor.
