Abstract
A touch sensor device includes a first panel, a second panel, and a drive-sense circuit (DSC). The first panel that includes first electrodes arranged in a first direction and second electrodes arranged in a second direction. The second panel includes third electrodes arranged in a third direction and fourth electrodes arranged in a fourth direction. The DSC is operably coupled via a single line to a coupling of a first electrode of the first electrodes and a first electrode of the third electrodes. The DSC is configured to provide the signal, which is generated based on a reference signal, via the single line to the coupling and simultaneously to sense the signal via the single line. The DSC generates a digital signal representative of the at least one electrical characteristic associated with the first electrode of the first electrodes and/or the first electrode of the third electrodes.
