RL78 Family TOUCH Module Software Integration System Rev.2.30
PDF 956 KB R11AN0485EJ0230 Rev.2.30 日本語 2026年3月24日
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.

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.

Some interrupt vector tables of the target devices (RL78/F22, F25) share multiple interrupt sources with one interrupt vector table. When using multiple interrupt sources assigned to the same interrupt vector table at the same time, it is necessary to determine which interrupt has occurred in the interrupt handler, or whether both interrupts have occurred.This application note describes how to determine the interrupt source when using both interrupt sources simultaneously.

RL78 Family TOUCH Module Software Integration System Rev.2.30
PDF 956 KB R11AN0485EJ0230 Rev.2.30 日本語 2026年3月24日
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.

RL78 Family CTSU Module Software Integration System Rev.2.30
PDF 1.58 MB R11AN0484EJ0230 Rev.2.30 日本語 2026年3月24日
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.
