1. A touch sensor device comprising:
a first panel that includes a first electrode;
a second panel that includes a second electrode; and
a drive-sense circuit (DSC) operably coupled to the first electrode and the second electrode, wherein the DSC is operably coupled via a single line to a coupling of the first electrode and the second electrode, wherein, when enabled, the DSC configured to:
provide a signal via the single line to the coupling of the first electrode and the second electrode and simultaneously to sense change of the signal via the single line, wherein the change of the signal is based on at least one of a first change of a first electrical characteristic of the first electrode or a second change of a second electrical characteristic of the second electrode; and
generate a digital signal representative of the first change of the first electrical characteristic of the first electrode or the second change of the second electrical characteristic of the second electrode;
memory that stores operational instructions; and
one or more processing modules operably coupled to the DSC and the memory, wherein, when enabled, the one or more processing modules configured to execute the operational instructions to:
process the digital signal representative of the digital signal representative of the first change of the first electrical characteristic of the first electrode or the second change of the second electrical characteristic of the second electrode to determine at least one of the first change of the first electrical characteristic of the first electrode or the second change of the second electrical characteristic of the second electrode.
