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. 一般的な説明 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, trackpad with gestures, touch screens, and proximity sensors. CapSense Gesture leverages CapSense CSD technology and adds gesture detection capability. CapSense Gesture converts capacitance of row and column electrodes to digital values. The given high level API functions use these raw digital values to determine finger location on a trackpad through interpolation algorithms. In addition it supports multitouch gesture decoding on-chip through simple API function calls. |
