摘要： A controller for a capacitive touch screen includes a touch resolve subsystem and a processor. The touch resolve subsystem, in response to a trigger input, measures a plurality of capacitance values using a plurality of input pins. The processor controls the touch resolve subsystem to acquire a baseline capacitance in a calibration mode, to acquire a frame comprising the plurality of capacitance values in a normal operation mode, and to update the baseline capacitance to a new baseline capacitance in the normal operation mode in response to the frame without entering the calibration mode.

摘要： A capacitive touch switch display control system includes multiple capacitive touch switches and respective LED displays that light to indicate the status of the system. A microcontroller unit (MCU) interface includes a shared function pin for each touch switch-LED pair. The MCU configures the shared function pin as an analog pin for very brief first time periods during which the MCU disables the LED displays and conducts capacitive sensing of the touch switches connected thereto to determine their status. After the first time period, the MCU enables the LED displays for potential lighting during a second time period. During the second time period, the MCU configures the shared function pin as a digital I/O LED control pin to either light or not light the LED display to indicate the status of the system. The first time period during which the MCU conducts capacitive sensing of the touch switches is sufficiently brief that it does not interfere with LED lighting function.
