AI 生成的摘要:
The CTSU module integrates capacitive touch sensing functions for RL78 microcontrollers, supporting multiple peripheral types with distinct features. It enables various measurement modes such as self-capacitance, mutual capacitance, and current measurement, with advanced functions including sensor correction, initial offset adjustment, multi-frequency measurements, shield functionality, and automatic judgment. Measurements can be triggered by software or external events, with results obtained via APIs. The module also supports diagnosis, moving average filtering, and temperature correction. Multi-clock measurements reduce noise, and calibration functions ensure accurate sensor readings. The document details API usage, hardware/software requirements, and operational modes, providing comprehensive guidance for integrating capacitive touch sensing in embedded systems.

AI 生成的摘要:
The TOUCH Module integrates capacitive touch detection using the CTSU hardware, supporting buttons, sliders, and wheels with configurable settings via QE for Capacitive Touch. It processes periodic capacitance measurements to determine touch states, employing baseline calibration, drift correction, hysteresis, and debouncing to ensure accurate touch detection and reduce noise. The module supports both self-capacitance and mutual-capacitance buttons, with majority judgment modes for reliable input. It provides APIs for initialization, scanning, data retrieval, sensitivity adjustment, and drift control, enabling flexible integration into RL78 microcontroller applications.

This is the Tool News announcing the revision upgrade to QE for Capacitive Touch V4.2.0, Development Assistance Tool for Capacitive Touch Sensors.
QE for Capacitive Touch is a tool for assisting in the development of embedded systems that include the use of capacitive touch keys.
This tool simplifies the initial settings of the touch user interface and the tuning of the sensitivity.
The main revisions are improvements to the sensor drive pulse frequency determined by automatic tuning (CTSU2) and support for the new device "RA0L1 Group, RL78/F22, RL78/F25, and RL78/L23".

AI 生成的摘要:
Capacitive touch sensors measure capacitance changes caused by finger contact using a sensor drive pulse and current measurement. Ripple noise from the power supply or peripheral circuits distorts these measurements by adding noise currents, causing inaccurate touch detection. To ensure high accuracy and reliability, power supply design must minimize ripple noise. The document explains measurement principles, ripple noise effects, and countermeasures including power supply circuit selection, switching circuits, board layout, and touch parameter tuning. It covers RX, RL78, and RA family MCUs embedding CTSU1 and CTSU2 types of capacitive touch sensing units.
