Overview

This document provides setup and installation instructions for the Touch Sensing Evaluation Board (TSSEVB), designed for developing capacitive touch applications on the S08 microcontroller family. The board utilizes the MC9S08LG32 MCU as the primary controller with an integrated LCD driver, alongside two MC9S08JM60 MCUs for open-source BDM debugging and GUI communication. The guide covers hardware identification of electrode types—such as keypads, sliders, and rotary sensors—and provides step-by-step instructions for installing CodeWarrior Development Studio, configuring USB drivers, and running pre-loaded demo application code for touch sensing evaluation.

Use Cases

  • Developing capacitive touch user interfaces
  • Evaluating NXP S08 family microcontrollers for touch sensitivity
  • Prototyping touch-controlled LCD applications
  • Testing slider and rotary electrode decoding structures
  • Setting up debugging environments for S08 based touch systems
