USB Drivers

Windows only, OSX and Linux users do not need to install drivers for USB support. Follow driver installation instructions in Driver Installation Documentation.

Software

LimeSuiteGUI

The LimeSuiteGUI is a powerful tool for configuring and debugging hardware platforms that are based around the LMS7002M transceiver chip. It allows you to view, edit, save and load the state of LMS7002M registers, perform board microcontroller firmware and FPGA gateware updates, and view FFT plots and configure various other on-board modules.

LimeSuiteGUI for Windows

The latest pre-compiled executable is LimeSuiteGUI_20170829_a15f8c.exe.

All the previous versions may be found here.

LimeSuiteGUI for other Operating Systems

How to build LimeSuiteGUI code from sources for other operating systems like Linux and OSX as well as Windows is explained here.
