Introduction
Different levels of immunity to conducted RF voltage are required by touch sensing systems, depending on the application. Moreover, touch sensing systems are often designed to meet the requirements of industry standards, especially in the EMC compliance domain.
It is important to understand the environment in which the touch application is used, and to apply suitably adapted techniques to address the effects of unwanted noise disturbances.
This document provides a basic overview of conducted immunity testing and some guidelines to keep the system reliable when it is exposed to conducted noise.
STMicroelectronics provides free STMTouch touch sensing firmware libraries, directly integrated into the corresponding STM32Cube package.
