STEP-BY-STEP INSTRUCTIONS

In this Quick Start Guide, you will learn how to set up the TWR-KM35Z75M board and

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

user manual at nxp.com/TWR-KM35Z75M.

1Download

Software

Download installation software

and documentation under

“Jump Start Your Design”

at nxp.com/TWR-KM35Z75M.

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 micro-B connector (J27) on

the TWR-KM35Z75M module. Allow the

PC to automatically configure the USB

drivers if needed.

4Confirm Segment

LCD

The Segment LCD displays as below:

• First, the digital numbers will display.

• Second,the icons will display one by

one.

• Finally, all segments on will blink, then

turn off.
