SEGGER introduces J-Scope, data visualization for J-Link

Hilden, Germany – July 29th, 2014 - SEGGER announces J-Scope, their new data visualization software for the industry standard J-Link family of debug probes. J-Scope is an application to analyze and visualize data on a microcontroller in real-time, while the target is running. It provides a real-time, accurate representation of the sampled variables enabling the engineer to better understand the embedded application.

J-Scope is based on the newly introduced J-Link HSS (High Speed Sampling) feature, which makes it possible to continuously sample variables at extremely high speeds without affecting the real-time nature of the embedded device. Using the standard debug interface, it does not require any extra resources on the target such as memory, CPU time or extra pins.

The periodic sampling is done autonomously by the J-Link. This allows considerably higher sampling rates and more precise timing than other debug probes. J- Scope uses this feature to read the target variable data and display both the value and an oscilloscope-like trace.

Examples of where HSS and J-Scope can be used is in monitoring network stack loads, or monitoring a 3-phase 50 Hz signal on a motor control application.

“The release of J-Scope makes it possible to display and analyze real-time behavior in a unique new way. A number of our clients have asked for this feature. Previously, those who needed to monitor variables have had to rework their application and attempt to use other communication interfaces to transmit this data with varying success. Having HSS available through the debug probe and also open through the J-Link SDK makes monitoring variables a lot easier,” says Alexander Gruener, Product Manager of the SEGGER J-Link family of debug probes.

J-Scope supports all CPUs with some form of background memory read, including most Cortex-M CPUs, and Renesas RX. More information on J-Scope can be found at http://www.segger.com/j-link-j-scope.html
