Welcome to the first post on getting started with using a Real-Time Operating System (RTOS) and Percepio Tracealyzer. In earlier posts we have talked a lot about how you can use Tracealyzer to find unwanted behavior in your RTOS-based system, but here and in a few later articles we will discuss how to actually do [...]
If you have kids and like to build stuff, you might have built a soapbox car at some point. At least I did last summer. For me, an obvious next step was to consider adding an electric motor. I never found the time, but would have loved a project like that. I therefore got quite [...]

An updated version is now available of Tracealyzer for FreeRTOS. This solves a minor issue with task names containing the substring "idle", which previously were mistakenly assumed to be the idle task (which is treated differently).
We have now released Tracealyzer for FreeRTOS version 3.0.5, with some improvements in the documentation and two bug fixes in the snapshot recorder.
When developing firmware using a Real-Time Operating System (RTOS), how do you measure the software performance? One important aspect of performance analysis is response time, the time from point A to point B in the code, e.g., from when a task is activated until it is completed. This can be measured in many ways, e.g., [...]
