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.

1. Download Software
   Download installation software and documentation under
   “Jump Start Your Design” at nxp.com/TWR-KM35Z75M.

2. Install Software and Tools
   Install the OpenSDA Tower Toolkit to install the OpenSDA and USB-to-Serial drivers.

3. Configure 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

4. Confirm 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.

5. Explore Further
   Learn more about KM series MCUs, find Sigma-Delta ADC performance and low power modes, as well as software peripheral drivers and additional labs at nxp. com/TWR-KM35Z75M.

EXPANDED SOFTWARE AND TOOLS
Additional details regarding the Quick-Start Demo are included as part of the MCUXpresso software development kit (SDK). To take your design to the next level, leverage the MCUXpresso SDK and other online enablement software and tools for NXP MCUs available at
