Application note

Guidelines for designing touch sensing applications

with projected sensors

Introduction

This application note describes the layout and mechanical design guidelines used for touch

sensing applications with projected sensors.

This document describes only what is specifically related to projected sensors, designed

using STM8L52/L53 microcontrollers. To have general tips and tricks for designing touch

application, please refer to AN4312.

Table 1 lists the microcontrollers concerned by this application note.
