Abstract
Touch sensing circuit arrangements include a touch sensor and a controller board. The touch sensor includes one or more sensing elements to generate touch-related signals responsive to a touch input to the sensor, and a memory device storing computer-executable firmware instructions for determining touch positions based on the touch-related signals. The controller board includes query logic executable by the controller board to cause the controller board to query for the computer-executable firmware instructions stored on the memory device of the touch sensor, and a processor circuit to determine touch positions by executing the firmware instructions loaded onto the generic controller board in response to the query.
