Linux is one of the great stories of the tech world, started in a Finnish dorm room and now it runs on 80 percent of public servers and 100 percent of supercomputers. But what percentage of embedded devices? The answer is, "a growing percentage". For the last 20 years, developers have been introduced to electronics […]

If you're a student, hobbyist, or serious embedded developer, you have had ample experience with UART. After all, it's the de facto serial communications protocol for connecting target development platforms to your development PC! But what about UART driver development? How versed in that are you? Regardless of the answer, in this week's Engineering Hour […]

In this lesson, DevHeads' embedded Linux experts will take us into fundamental concepts that form the backbone of Yocto, Poky, and OpenEmbedded. Understanding these differences is crucial for navigating the world of embedded systems development effectively. What is Yocto? Yocto is not just a single entity but rather a collection of tools and metadata used […]

These days the up-and-coming RTOS isn't something proprietary. And you might be surprised to know it's also not FreeRTOS. Meet Zephyr. Zephyr is a Linux Foundation project, which explains based on devicetree configuration and CMake build system. But wait, didn't you say it was an RTOS? Join this DevHeads Office Hours session as developer and […]

In the last Engineering Hour we reviewed driver development for the UART protocol. This week, we’re moving onto I2C drivers. So, on Sunday, June 2nd, get ready to dive into I2C: * Protocol * Frame format * Slave addresses * Interfacing with other I2C devices After we get through that overview, stick around for a […]

Let's focus on setting up a Git repository tailored to the unique requirements of Yocto projects. By following these custom guidelines, you'll streamline your development process, enhance collaboration, and ensure the integrity of your Yocto build. * Choose the Right Repository Structure ** Layer-Based Approach ** Separate Repositories for Custom Layers ** Configuration Files ** […]

Everyone everywhere is investigating ways they can use AI to increase efficiency, improve productivity, and open new revenue streams or cost savings. Electronics engineering is no exception, where the application of AI and machine learning is already being investigated in use cases like VLSI (well, maybe that's EDA), board layout, and more. But where else […]

Embedded systems developers are all too familiar with the SPI interface. Are you? Join us for this week's Engineering Hour where tenured embedded and IoT developer Umesh Lokhande walks us through SPI driver development with an overview of: - SPI Protocol - Frame Format - Clock Polarity (CPOL) and Clock Phase (CPHA) - Connecting MCU […]

Let's dive into the concept of Software Bill of Materials (SBOMs) and their significance in Yocto projects. Understanding SBOMs is essential for ensuring transparency, security, and compliance in embedded Linux development. * What is a Software Bill of Materials (SBOM)? ** A Software Bill of Materials (SBOM) is a detailed inventory of all software components […]
