When debugging or profiling your firmware, it is often important to trace Interrupt Service Routines (ISRs) such as timer interrupts or interrupts from communication interfaces. However, using a classic ”printf” call is typically not an option since it may increase the execution time of the ISR by orders of magnitude. The integrated ”exception trace” support [...]
Tomorrow Friday is a special day here at Percepio HQ – we're moving offices. We are not moving very far, the new office is a ten-minute walk from our current one, but it is absolutely a step up for the company. We'll have our own offices with plenty of space to grow (and we are [...]
I (Mike) was travelling to Barcelona for the RISC-V Workshop earlier this month. As I walked through the Barcelona airport I looked up and saw some big ass fans. I took a quick picture, enlarged the logo, and sure enough – it really was a Big Ass Fan! It's always cool to see a Tracealyzer customer's [...]

Since Percepio is based in Sweden, which is a member of the European Union, and have a lot of [...]
When you open a trace in Tracealyzer, it usually opens to the vertical timeline. This view, which shows all activity in the system, is in many ways the core of Tracealyzer and most of the other views link back to the timeline, but with its massive amount of information it is not always the best [...]

The use of a Real-Time Operating System (RTOS) is increasingly common in embedded software designs. An RTOS makes it easy to divide your code into smaller blocks, tasks, which execute seemingly in parallel and independent of each other, as described in the first article in the RTOS 101 series. Having fully independent tasks is [...]
Steve Evans of Open Pilot Next Generation (OPNG) explains how they have used Percepio Tracealyzer to finely tune their flight controllers and ensure deterministic performance.
