4 EVM GUI Control Application
The GUI application is written with Texas Instruments’ GUI Composer, and can be run directly from a Chrome-
based web browser, or installed onto your computer. Because GUI Composer apps are written with a NodeJS
backend, the GUI application is cross-platform compatible by design. This document will only cover installation
on a PC for sake of brevity, but Mac and Linux users can find installers in the
GUI Composer Gallery .
4.1 MSP430 FET Drivers
The MSP430 FET Drivers are required for the operating system to properly enumerate the JTAG and UART
ports created by the EZFET_LITE. The latest drivers can be found here:

Download the driver package corresponding to your operating system, extract the archive, and run the installer.
In Windows, two new ports should be enumerated when the EVM is connected Figure 4-1 :
