お客様の 3 Phase Inverter Evaluation Kit for Semikron eMPack Featuring GD3160
1. Out of the Box
The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost and improved performance in powering state-of-the-art systems.
This page will guide you through the process of setting up and using the RDGD31603PSMKEVM reference design.

3. Get Software
Software for RDGD31603PSMKEVM is distributed with the FlexGUI tool (available at nxp.com). Necessary firmware comes pre-installed on the FRDM-KL25Z with the kit.
Even if the user intends to test with other software or PWM, it is recommended to install this software as a backup or to help debugging.
3.1 Install FlexGUI on Your Computer
The latest version of FlexGUI supports the GD3100 and GD3160. It is designed to run on any Windows 10 or Windows 8 based operating system.
- Go to FlexGUI and click Download
- When the FlexGUI software page appears, click Download and select the version associated with your PC operating system
- FlexGUI wizard creates a shortcut, an NXP FlexGUI icon appears on the desktop. By default, the FlexGUI executable file is installed at C:\flexgui-app-des-gd31xx.exe
Installing the device drivers overwrites any previous FlexGUI installation and replaces it with a current version containing the GD31xx drivers. However, configuration files (.spi) from the previous version remain intact.
4. Configure Hardware
