PSOC™ 4 Capacitive Sensing (CAPSENSE™ CSD)
Überblick
General Description
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.
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.
