More Information
Summary:A sensor controller, which is connected to sensor electrodes and detects positions of one or more active pens based on charge induced on the sensor electrodes, includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the sensor controller to: detect an approach of one of the one or more active pens using the sensor electrode; pair with the one of the one or more active pens with the approach of the one of the one or more active pens detected and update pairing state information indicative of a pairing state of each of the one or more active pens that is paired with the sensor controller; and transmit the pairing state information from the sensor electrodes to the one or more active pens via an uplink signal used as a reference for time synchronization.
