Hardware abstraction layers (HALs) are an important layer to every embedded software application. A HAL allows a developer to abstract or decouple the hardware details from the application code.

This lesson starts a new segment about Object-Oriented Programming (OOP) — an important set of concepts critical to understanding any modern software, not just modern embedded software. As usual in ...

Embedded systems have always been about squeezing every ounce of performance from limited hardware. From hand-optimized assembly to finely tuned C, we’ve spent years writing efficient code, minimizing ...
