PSoC 4 Capacitive Sensing (CapSense® CSD)
Note This document refers to PSoC 4 devices throughout. References to PSoC 4 should be interpreted to mean PSoC 4 and PSoC 4 BLE (Bluetooth Low Energy) devices. This component also supports the PRoC BLE device.
Capacitive sensing using a Delta-Sigma Modulator (CapSense CSD) is a versatile and efficient way to measure capacitance and detect finger touches in user interface panel applications such as capacitive touch buttons, sliders, touchpads, touch screens, and proximity sensors.
