Abstract: A touch sensor device (TSD) includes a panel that includes electrodes and drive-sense circuits (DSCs). Different electrodes may be implemented in different directions. A first DSC is operably coupled via a first single line to a first electrode, and a second DSC is operably coupled via a second single line to the panel. The DSCs operate by providing respective signals via the respective single lines and simultaneously sensing the signals. For example, sensing of a first signal of a first DSC includes detection of a first electrical characteristic of the first electrode and/or a first change of the first signal. Sensing of a second signal of the second DSC includes detection of coupling of another signal into the panel in accordance with digital data communication from another device to the TSD. The DSCs also generate respective digital signals based upon what they sense.
