概述
描述
本参考设计介绍了一款基于 RL78/G22 及其电容式触摸传感单元（CTSU2La）的家用电器面板 UI 演示方案，旨在帮助评估低功耗电容式触摸界面。 该演示方案采用多电极连接（MEC）功能，将多个触摸电极输入的信号视为单一输入，从而能够以更少的扫描次数和更低的功耗实现高效的待机唤醒检测。 通过调整灵敏度，该方案同样支持接近式感应，因此适用于早期 UI 概念的评估和设计研究。
特性
- 采用 RL78/G22 MCU
- 采用 RSSK-RL78G22 套件中的 RL78/G22 CPU 板，以及包含 7 个自电容式按钮和 25 个 LED 的电极板
- 前面板的同一电极既可作为触摸按钮，也可作为非接触式传感器
- MEC 功能支持通过单次测量对多个电极进行感应
- 通过 MEC 功能实现低功耗

AI 生成的摘要:
The document explains the Multiple Electrode Connection (MEC) function that treats multiple touch electrodes as a single electrode to reduce scanning time and power consumption. It demonstrates a home appliance UI with seven touch buttons, which operate independently in normal mode and combine into one electrode in standby mode using MEC. This allows waking the device from standby by touching any electrode. The document includes hardware configuration, sample software flowcharts, current consumption measurements, and design files such as schematics and BOM for the electrode board.
