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.
