Classification: CPC G | IPC G

Claim 0:
1. A touch sensor device (TSD) comprising:
a plurality of TSD electrodes associated with a surface of the TSD;
a plurality of drive-sense circuits (DSCs) operably coupled to the plurality of TSD electrodes, wherein a DSC of the plurality of DSCs is operably coupled to a TSD electrode, wherein, when enabled, the DSC configured to:
generate a TSD electrode signal based on a reference signal;
provide the TSD electrode signal, via a single line, to a TSD electrode of the plurality of TSD electrodes and simultaneously to sense, via the single line, a change of the TSD electrode signal based on a change of impedance of the TSD electrode; and
generate a digital signal that is representative of the change of impedance of the TSD electrode;

a communication interface;
memory that stores operational instructions; and
one or more processing modules operably coupled to the plurality of DSCs, the memory, and the communication interface, wherein, when enabled, the one or more processing modules is configured to execute the operational instructions to:
process the digital signal to determine the change of impedance of the TSD electrode; and
facilitate communication with a computing device via the communication interface.
