Application note

Tuning a STMTouch-based application

1

Introduction

This document is intended for touch sensing application designers and provides guidelines

on how to tune their system. STM Studio tool is introduced and information is provided on

how to use it in order to monitor the variables. A particular emphasis will be placed on

providing a methodology to configure the STMTouch library parameters.

This document shows how to trim firmware parameters and adjust hardware components to

optimize the performance of your application.

This document is not intended to replace product documentation and library user manual

All values given in this document are for guidance only. Please, refer to the related

datasheet to get guaranteed values.

Note:

STMicroelectronics is providing free STMTouch touch sensing firmware libraries which are

available either as standalone packages (STM8L-TOUCH-LIB) or directly integrated into the

corresponding STM32Cube package (STM32CubeL0, STM32CubeF0, …).
