Seeing Inside the Scheduler

Mar 6, 2026

RTOS applications rarely fail because a single task is misbehaving. Instead, problems emerge from interactions that are often invisible at the code level.

Mars-Level Insight for Embedded Systems

If you’ve ever wished you could see exactly what’s happening inside your firmware – every subtle timing hiccup, every task that occasionally runs too long – you’re going to want to stop by at our Embedded World booths

Max Maxfield – “Well, Fork Me with a Dining Philosophers Problem”

Mar 1, 2026

One question I’m often asked—and one I often ask myself—is, “How many people are currently involved in developing embedded systems?” Counting engineers is a slippery problem (especially mechanical engineers, because they are often dripping in oil). I’d hazard a guess that there are probably between 2 and 4 million embedded professionals globally (depending on how we define ‘embedded’ and ‘professionals’), including both hardware designers and software/firmware developers.

Now I have another question for you. How many embedded system development teams around the world are using the tools from Percepio? The answer to this one is easy: “Not as many as there should be!”

5 Tips for Mastering Zephyr RTOS

Jul 9, 2025

Right now, interest in Zephyr is snowballing. The project already supports more than 780 boards and 150 shields, but what really sets it apart is more than just its technical flexibility.

Naming your kernel objects

Jun 24, 2025

When using Percepio Tracealyzer and TraceRecorder, you may have noticed that thread names show up automatically, while other kernel objects (like queues or semaphores) are only displayed as hexadecimal numbers. But in the demo traces, all kernel objects have proper...
