SEGGER introduces scope-like data visualisation with new dataplot feature in SystemView

SystemView’s new data recording capability allows developers to capture variable data alongside runtime events. The DataPlot window then visualises this data in synchronised scope-like graphs, integrating seamlessly with SystemView’s Timeline and CPU Load windows. This synchronised view provides context on variable values and system behaviour, helping developers verify correct operation or diagnose unwanted behaviour.

Erich Styger, Lecturer, Professor, and Researcher, praised the addition: “The ability to send and show data in SystemView had been on my SEGGER wishlist. It has been very helpful for monitoring multiple sensor values, dynamic memory usage, power profiles, and control algorithm inputs and outputs. Thank you, SEGGER!”

“SystemView is a unique tool for understanding exactly what is happening in an embedded system,” says Johannes Lask, Product Manager of SystemView at SEGGER. “It traces interrupts, task switches, API calls, and other user events with cycle accuracy, typically better than 5 ns. SystemView is free for evaluation and non-commercial use under SEGGER's Friendly License. No additional hardware is required—just download and try it!”

For example, developers can monitor power consumption in a system by recording the data with SystemView. The DataPlot window displays this data in real-time, allowing users to pinpoint spikes in current or power usage and correlate them with specific tasks or events.
