The Interrupt community comprises engineers, hobbyists, and enthusiasts with a shared passion for hardware and firmware development. We come together to share best practices, problem-solve, collaborate on projects, advance the embedded community, and elevate device reliability engineering (DRE).
The Interrupt Community was created and is moderated today by the founders of Memfault.
As the first segment of a three-part series on JTAG, this post will give an overview of JTAG to set up some more in-depth discussions on debugging and JTAG Boundary-Scan. We will dive into the intricacies of the interface, such as the Test Access Port (TAP), key registers, instructions, and JTAG’s finite state machine.
If you’ve ever wanted to plot data acquired on your embedded target, this article is for you. It explores common use cases for real-time data visualization using STMViewer. Say goodbye to manual, time-consuming, and error-prone data collection and display methods to speed up your debugging process.
This post will cover the most common reliability metrics that hardware manufacturers use. It will explore which are best for IoT devices, including a novel measurement, Crash Free Hours. We’ll cover exactly what you’ll need to collect on your devices within firmware to measure device reliability and ensure your devices are working as expected.
Here are the articles, videos, and tools that we’ve been excited about this October.
At Memfault, our love affair with Rust began in late 2022. What drew us to Rust? Well, the typical allure of a modern programming language: an impressive type-system, memory safety without the constant jitters, efficient concurrency management, a thriving package ecosystem, and overwhelming support from our engineering team. To put it simply, we’re smitten. Our journey with Rust has been nothing short of transformative, enabling rapid progress and leading us to conquer challenges we previously deemed … non-trivial.
Memfault is the first cloud-based observability platform for connected device debugging, monitoring, and updating, which brings the efficiencies and innovation of software development to hardware processes. Recognizing that any connected device team could benefit from what they were building, François Baldassari, Chris Coleman, and Tyler Hoffman founded Memfault in 2018 with the help of colleagues from Pebble.
