J-Link control panel

The J-Link control panel is a browser user interface based on emWeb.

Image shows a web control panel for J-Link, displaying general device information such as process, module, version, selected device, voltage, target interface, and USB interface details. The manufacturer's logo is visible at the bottom.

The J-Link control panel provides an easy way to monitor and configure J-Link as well as J-Trace probes.

Information about power usage, connection status, operating speed, firmware version, heap fragmentation and much more can be found inside the web control panel.

A target power chart shows voltage levels with blue indicating the USB voltage at 3.73V and the target at 0V. Current levels are also displayed: a steady green line for current at 0.247A and a red peak at 0.307A.

Due to the interface being handled by the browser, the web server does not depend on the operating system nor the host, making it accessible from any device with a browser. The interface is generated by the web server on your machine and can be made available over the Internet.

Therefore there's no need to install or download any software at all.

Furthermore, this enables other software, e.g. Embedded Studio, to include it inside of its own GUI.

A computer screen displaying coding and debugging environments. The interface includes project files on the left, a code editor in the center, and a control panel for web settings on the right. Below, there's a debug terminal with messages about server warnings and memory issues.

Data from connected probes is gathered and analyzed via JavaScript, AJAX and SSE, creating a live-updating and visually appealing user interface.

The J-Link control panel runs on the J-Link Built-in web server and is available for all J-Links.
