Portable firmware is more than just migrating code across hardware platforms. It involves organizing firmware in a modular, scalable, and reusable way while adhering to better design principles.

This talk begins with a personal story of challenges and setbacks, shedding light on common pitfalls and ineffective approaches. It then explores the principles and patterns essential for creating portable firmware for embedded systems, illustrated with simple examples in C.

Attendees will learn how to develop adaptable firmware capable of running on different microcontrollers and hardware configurations with minimal changes to the application code.
