Continuous Integration for Embedded Systems

Tayyar GUZEL ● September 5, 2017●2 comments

Hardware dependencies make continuous integration for embedded systems harder than for pure software, yet it is essential for quality and faster feedback. This post explains the three CI types, host, non-host and hardware-in-the-loop, then compares trade-offs in cost, parallelism, timing accuracy and portability. It also outlines steps in a typical CI pipeline and highlights practical tools and plugins, including Jenkins and static analysis to automate builds and tests.

Best Firmware Architecture Attributes

Tayyar GUZEL ● June 4, 2016●6 comments

A poor firmware architecture makes future product variants and team work costly; Dr. Tayyar GUZEL outlines the attributes that avoid that fate. The post emphasizes modularity, low coupling, and encapsulation, and shows how a hardware abstraction layer, blackboard pattern, and CI-based unit testing improve extensibility, portability, and robustness. Practical tips include using setter/getter APIs, Doxygen for dependency graphs, and nightly regression to catch interface breaks early.
