TWR-KM34Z50M Freescale Tower System

Development Board Platform

The TWR-KM34Z50M board is designed to work either in standalone mode or as

part of the Freescale Tower System, a modular development board platform that

enables rapid prototyping and tool re-use through reconfigurable hardware. Take

your design to the next level and begin constructing your Tower System rapid

prototyping platform today by visiting freescale.com/Tower for additional Tower

System boards and compatible peripherals.

Installation Instructions

In this Quick Start Guide, you will learn how to set up the TWR-KM34Z50M board and

run the included demonstrated software. For more detailed information, review the user

manual at freescale.com/TWR-KM34Z50M.

Download Software

and Tools

Download installation

software and documentation

under “Jump Start Your

Design” at freescale.com/

TWR-KM34Z50M.

2Install Software

and Tools

Install the OpenSDA Tower Toolkit to install

the OpenSDA and USB-to-Serial drivers.

3Configure the

Hardware

Connect one end of the USB cable to

the PC and the other end to the Power/

OpenSDA mini-B connector (J14) on the

TWR-KM34Z50M board. Allow the PC

to automatically configure the USB drivers

if needed.

4Segment

LCD

All segments are turned on for three

seconds, then potentiometer readings are

displayed. The LEDs should be blinking.

5Move the

Potentiometer

The onboard LCD shows the SAR-ADC

reading.
