Percepio's stand at ArmTechCon. ArmTechCon 2017 is over and we have packed up and left. We spent two days talking to users and meeting partners, and we showed the upcoming Tracealyzer version 4 for the first time. We will have more to say about both Tracealyzer 4 and ArmTechCon in the coming weeks, but there's one little [...]
Priority inversion at work – the high-priority (red) task is blocked by lower priority tasks. The central idea underlying an RTOS with a fixed-priority scheduler is that a high-priority task should be scheduled ahead of one with lower priority. If necessary, the RTOS can even pre-empt the running task, forcing it to yield the CPU to [...]
Our Korean distributor Dioiz is running a hands-on seminar on embedded development with, among other tools, Tracealyzer this week. It is sold out by now, but there will be a second event on November 22 and Dioiz has let us know that applications are welcome. More info here – note though that both the invitation and the [...]
When you have a task in your system that is supposed to execute at regular intervals, say for instance that it needs to read a sensor value every 5 milliseconds, then you have a system that is sensitive to random delays – also known as “jitter”. When your task experiences jitter, it sometimes has to [...]
Industry veteran Cliff Wood today joins Percepio as Sales Manager for USA and South America. – Cliff has been working with Percepio informally for some time and many of our U.S. customers may have met him, but today we are happy to welcome him as Percepio’s first regional Sales Manager, says Percepio CEO Johan Kraft. Cliff [...]
The ”theme” of this year’s Arm TechCon conference is of course … Arm. Over 4000 embedded systems specialists are expected to descend upon Santa Clara, California, in two weeks to discuss all things Arm, from silicon design and software development to computer vision and the Internet of Things. Among these enthusiasts is of course a [...]
In embedded systems using multitasking, you may run into a situation where some of your tasks run slowly or not at all. This is called task starvation (the affected tasks are starved of CPU time) and it can happen for a number of reasons; today we will look at one particular reason – a fixed [...]
Tracealyzer v3.2 adds powerful filtering functions to reduce the amount of data that must be sent to the monitoring host computer. This makes Tracealyzer applicable to a wider range of development setups. Today we are happy to present version 3.2 of Tracealyzer for FreeRTOS. The new version is available for download from percepio.com/download/ immediately. [...]
There is no doubt a learning curve when you begin using a real-time operating system (RTOS) in your development. You will work at a higher abstraction level, using more or less parallel tasks rather than just subroutines, and you will need to consider how your tasks shall share data and the processor time with each [...]
Photo: Sara Arnald, CC-BY Have you ever wanted to debug your hobby MCU project with a tracing tool, but felt that you couldn't afford a pro tool like Percepio Tracealyzer? Well, now you can! From now till the end of this year, you can purchase a non-commercial Tracealyzer Makers Edition license at the heavily discounted price [...]
A research group at Mälardalen University here in Västerås, Sweden, is investigating how RTOS trace tools like Percepio Tracealyzer can be extended for testing purposes and automatically detect bugs related to concurrency and timing. To validate their research, they need real-world bug examples. We at Percepio want to help them obtain RTOS traces, recorded with Tracealyzer, [...]
Embedded Conference Scandinavia 2017 will be in Stockholm, Sweden on 7–8 November. Please see our blog post for further details.
Sensors Midwest takes place in Rosemont outside Chicago on October 3–4. See our blog post for details.
Embedded Conference Scandinavia, ECS, takes place on 7–8 November, 2017 at Kistamässan in Stockholm, Sweden. Last year’s conference attracted just under 2,000 delegates so ECS now claims to be the largest embedded conference in Europe. The conference program is still in flux but the organizers have announced the first keynote speaker: Maarten Struys, Account [...]
Synopsys ARC Processor Summit is a free one-day event where you can pick from any of 25+ technical seminars on embedded development and electronic design. This year’s Summit takes place on September 26 and Percepio will be there discussing how to catch bugs in RTOS-based programming. Once again we are represented on the stage by [...]
Percepio’s Field Application Engineer Niclas Lindblom will talk about using Percepio Tracealyzer to debug common timing issues in RTOS applications at the Microchip MASTERs tech conference in the U.S. in August. Niclas shares a four-hour class with Darren Wenn, Global Group Leader for embedded development at Microchip, and they will focus on the combination of [...]
Percepio’s Field Application Engineer Niclas Lindblom will talk about using Percepio Tracealyzer to debug common timing issues in RTOS applications at the Microchip MASTERs tech conference in Berlin in September. Niclas shares a four-hour class with Darren Wenn, Global Group Leader for embedded development at Microchip, and they will focus on the combination of Tracealyzer [...]
Summer is finally approaching here in Sweden. Last Friday we celebrated Midsummer, and the coming weeks will be a bit slower than usual as most Swedes check out from work and enjoy their summer vacation. But only a bit slower, mind you: the lights will stay on at Percepio HQ as we work on new [...]
You may have heard about "Running Snail", a team of German university students building an electric race car as a school project – we blogged about them last year. Now they're at it again, they will build a new car for the 2017/18 competitive season, and of course Percepio will continue to sponsor the team with licenses [...]
