| Features |
an increased internal intelligence plus Freescale’s second generation capacitance detection engine. Some major enhancements include an increased electrode count, a hardware configurable I2C address, an expanded filtering system with debounce, and completely independent electrodes with built-in autoconfiguration. The device also features a 13th
simulated electrode which represents the simultaneous charging of all the electrodes connected together. When used with a touch panel or touch screen array, the 13th simulated electrode allows a greater near proximity
detection distance and an increased ... |
