Discover the differences between SWD and JTAG, including wiring, debugging performance, flashing firmware, and ARM-specific features for embedded systems.

Explore JTAG fundamentals, scan chains, boundary-scan testing, and debugging techniques for developing, testing, and programming embedded systems.

Learn JavaScript fundamentals including variables, loops, functions, DOM manipulation, and events to build interactive websites with confidence.

Explore JSON structure, data types, nesting, and syntax rules to build valid, efficient files for APIs, applications, and local data storage.

Learn YAML fundamentals, including scalars, sequences, mappings, strings, comments, and best practices for readable configuration files.

Learn how challenge-response authentication, nonces, and cryptographic MACs help embedded systems defend against replay attacks.

Explore the strengths and tradeoffs of MicroPython, Zephyr, Lua, and Forth for embedded development and rapid prototyping.

If you've ever stood in front of a classroom full of students while an XRP robot starts driving in unexpected circles and you're not entirely sure why — this post is for you.

Learn how rolling counters and cryptographic MACs prevent replay attacks, authenticate devices, and strengthen embedded security.

Find out how the brain's default mode network supports debugging, learning, and creative problem solving during short breaks.

Learn how replay attacks exploit repeated unlock messages, why authenticity matters, and how embedded systems can defend against them.

Learn how JavaScript event handlers respond to user actions, attach and remove listeners, access event data, and manage propagation.

We're going to move from theory to practice. We'll run our first container, build a custom Python application, and look at when and when not to use Docker in your projects.

Understand how memory read attacks work on MCUs and how to defend using debug disable, encryption, and hardware protection features.

Creating a low-cost prosthetic arm is challenging, but making one that is also easy to calibrate and accurate is even tougher.

Explore how attackers gather device info, map inputs, and uncover vulnerabilities using reconnaissance in embedded hardware security.

In this post, I want to explain what Docker is, why it helps with these problems, and give a practical understanding of how it fits into development workflows.

Explore a hardware security workflow using firmware builds, simulation tools, serial commands, and automated tests for microcontroller systems.

Follow the setup and programming process for the VeryVerilog kit, including firmware loading and exploring built-in logic demos.

Learn how Microchip’s CLB, CLC, and AVR CCL peripherals enable gate-level functions without external hardware.
