Adopting Test-Driven Development in Embedded Systems

Embedded software development has long been characterized by unique constraints such as limited resources, strict real-time requirements, and complex interactions with hardware. As a result, traditional software development methodologies often fail to translate smoothly into the embedded space. However, modern embedded development is evolving, and techniques like Test-Driven Development (TDD) are no longer just for web and enterprise applications: they're essential for building reliable and maintainable embedded systems.

Introduction to Flutter State Management

As Bob continues this article series on Mobile App development from an Embedded System's perspective, he tackles State and State Management in Flutter. As you will see, it is very different from what embedded engineers are used to when we think of state and that misunderstanding can cause no end of trouble if we don't understand it.
