The CapSense® Successive Approximation Multifrequency Scanning (CSAMFS) User Module implements an array of capacitive touch sensors using switched capacitor circuitry, an analog multiplexer, digital counting functions, and high level software routines to compensate for environmental and physical sensor variations. The sensor array can consist of combinations of independent sensors, sliding sensors, and touchpads implemented as a pair of orthogonal sliding sensors. High level software routines accommodate slider diplexing. Slider diplexing allows a single pin to measure two electrical sensors in two different physical locations. Diplexing provides resolution enhancement of the slider without the cost of an additional I/O.
