Zephyr: West Manifest For Application Development
In this blog post, I show a simpler way to create custom West manifest files. This technique eliminates the need to duplicate the complex West manifest from upstream Zephyr. I also show how we can use the West manifest to include out-of-tree board and SoC definitions, and include our own out-of-tree drivers.
Simulating Your Embedded Project on Your Computer (Part 2)
Having a simulation of your embedded project is like having a superpower that improves the quality and pace of your development ten times over! To be useful, though, it can't take longer to develop the simulation than it takes to develop the application code and for many simulation techniques "the juice isn't worth the squeeze"! In the last article, I showed you how to use the terminal (i.e. printf/getchar) to easily make a completely functional simulation. In this article, we'll take simulation to the next level, either in terms of realism (by using virtual hardware) or in terms of user experience (by using a GUI to simulate our hardware, instead of using the terminal).

Understanding Yocto Project Layers: A Modular Approach to Embedded Systems Development
Managing metadata across embedded Linux builds gets messy fast, so the Yocto Project uses layers to keep things modular and reusable. This post walks through inspecting active layers with bitbake-layers, controlling overrides with BBFILE_PRIORITY, and creating a meta-yocto-splash-img layer that uses a .bbappend to replace psplash. It finishes by showing how to verify the custom splash screen in QEMU so you can test safely before deploying to hardware.
Small or fast?
Developers of software for desktop computers take code optimization for granted. Embedded developers typically need to pay much more attention to the details
Stand-by or boot-up
Many factors affect the usability of devices - a key one is how long it takes to start up.
Write Better Code with Block Diagrams and Flowcharts
Reading and writing code without architectural diagrams is like trying to follow complex instructions without any explanatory pictures: nigh impossible! By taking the time to draw out the block diagrams and flowcharts for your code, you can help identify problems before they arise and make your code easier to design, write, test, and debug. In this article, I'll briefly justify the importance of architectural drawings such as block diagrams and flowcharts and then teach you what they are and how to draw them. Using two simple examples, you'll see first-hand how these drawings can significantly amplify your understanding of a piece of code. Additionally, I'll give you a few tips for how to implement each drawing once you've completed it and I'll share with you a few neat tools to help you complete your next set of drawings.

How to Achieve Deterministic Behavior in Real-Time Embedded Systems
Ensuring deterministic behavior in real-time embedded systems is paramount for their reliability and performance. The ability to predict precisely how a system will respond to various inputs at any given time is crucial in critical applications such as medical devices, aerospace systems, and automotive safety mechanisms. Achieving deterministic behavior involves meticulous design, stringent testing, and adherence to strict timing constraints.
VHDL tutorial - A practical example - part 2 - VHDL coding
Gene Breniman walks through the VHDL coding for a CPLD-based data acquisition engine, turning the hardware spec into a working state machine and signal generators.

Finite State Machines (FSM) in Embedded Systems (Part 2) - Simple C++ State Machine Engine
When implementing state machines in your project it is an advantage to rely on a tried and tested state machine engine. This component is reused for every kind of application and helps the developer focus on the domain part of the software. In this article, the design process that turns a custom C++ code into a finite-state machine engine is fully described with motivations and tradeoffs for each iteration.

C++ on microcontrollers 1 - introduction, and an output pin class
Wouter van Ooijen shows how small C++ abstractions make GPIO code portable and reusable. Starting from a simple output_pin interface he implements concrete pins for an LPC2148 GPIO and a 74HC595 shift register, then composes behaviors with wrappers like tee and invert. The post demonstrates virtual methods, references, and constructor initialization lists to build drivers you can reuse across boards.
10 Software Tools You Should Know
Embedded work gets a lot easier when you have the right software stack, and Jason Sachs lays out the tools he leans on every day. From revision control and file comparison to build systems, scripting, analysis, documentation, QA, and command-line utilities, he focuses on practical picks that save time and reduce mistakes. The list is opinionated, but it is full of the kind of workflow advice that helps engineers stay productive.
Important Programming Concepts (Even on Embedded Systems) Part V: State Machines
State machines are not glamorous, but they solve a lot of real embedded problems. Jason Sachs uses a motorized couch example to show how FSMs and Harel statecharts expose corner cases, simplify timing constraints, and make behavior easier to specify and review. The article walks through hand-rolled switches, tabular implementations, the state pattern, libraries like QP and Boost, and tool tradeoffs.
Data Hiding in C
You can get C++-style data hiding in plain ANSI C, Stephen Friederichs demonstrates how with a FIFO stack example. He shows opaque pointer typedefs to hide struct layouts, const-qualified handles to catch accidental writes, static file-local functions for private helpers, and a canary field to detect tampering. The pattern keeps the public header stable while letting you change implementations behind the scenes.
Implementing State Machines
Stephen walks through a practical state machine example using a dish-washing analogy to expose common implementation pitfalls and fixes. Starting from a straightforward superloop design he shows how blocking loops, global state, and interrupt races can break behavior, then refactors the code to use scoped enums, non-blocking state actions, and a simple interrupt flag to make embedded state machines safer and more maintainable.
Learning Rust For Embedded Systems
Rust eliminates whole classes of memory and concurrency bugs, making it a compelling choice for embedded projects, and the author recommends it for the VolksEEG project after a rapid evaluation. The post connects Rust fundamentals such as ownership and borrowing, RAII, traits, and unsafe blocks to familiar embedded patterns. It also provides a curated on-ramp of videos, books, and tools like Cargo, RTIC, and probe-rs to get hands-on quickly.
Skills For Embedded Systems Software Developers
Embedded development demands a broad, practical skillset, and this post lays out the core knowledge employers expect across software, hardware, and tooling. It highlights essential languages like C, low-level concepts such as interrupts and RTOS, plus hardware skills like debugging with JTAG and using oscilloscopes. You also get realistic timelines, hands on study advice, and resource pointers to build a portfolio that proves you can ship reliable firmware.

Whether you've only just finished your first Arduino project or you've been building embedded systems for decades, I believe there's something in here for everyone to help improve themselves as embedded systems engineers.
Unit Tests for Embedded Code
Unit tests are one of the most effective ways to catch logic bugs early and protect embedded firmware against regressions. Stephen Friederichs explains why unit testing matters for microcontroller code, when to test, and the trade-offs between on-target and hosted approaches, with practical advice on stubbing, using the Check framework, simulators, and coverage tools to make testing realistic for embedded projects.
