CE64134 - Measuring Absolute Sensor Capacitance with a CY8C20xx6A CapSense® Controller http://www.cypress.com/?rID=46696 CapSense systems detect the presence of a touch by monitoring changes in measured sensor capacitance, known as raw counts. The discrimination of touch events from random noise are based solely on the differences in sensor capacitance (or raw counts) caused by a touch. However, there are times when measuring the absolute as opposed to relative capacitance is useful. Tuning is one example. To tune a CapSense system, the absolute capacitance of the sensors must be known. This code example measures the absolute capacitance of sensors with parasitic capacitance (Cp) up to 60pF to within 1pF accuracy. The results are displayed on a personal computer using Windows HyperTerminal.
