Embedded Systems
Comprehensive tutorials on embedded systems — from microcontroller basics and GPIO to RTOS, power management, and security. All examples use C code targeting real hardware.
Dependency Inversion Principle (DIP) in C
Learn the Dependency Inversion Principle with practical C examples. See how depending on abstractions (function pointers) instead of concrete implementations makes code flexible and testable.
DRY Principle (Don’t Repeat Yourself) in C
Learn the DRY principle with practical C examples. See how eliminating code duplication with functions and macros makes code easier to maintain and less error-prone.
YAGNI Principle (You Aren’t Gonna Need It)
Learn the YAGNI principle with practical C examples. See how building only what you need today avoids wasted effort, code bloat, and unnecessary complexity.
Composition Over Inheritance in C
Learn the Composition Over Inheritance principle with practical C examples. See how embedding structs and assembling behavior creates more flexible and maintainable code than deep… Read More »Composition Over Inheritance in C
Separation of Concerns in C
Learn Separation of Concerns with practical C examples. See how dividing code into distinct sections — each handling one concern — makes software modular, testable,… Read More »Separation of Concerns in C
Git Version Control for Embedded Developers
Learn Git version control for embedded systems development. Covers essential commands, branching, .gitignore for firmware projects, commit best practices, and team workflows.
Debugging Embedded Systems: Tools and Techniques
Learn essential debugging techniques and tools for embedded systems including serial debugging, LED toggling, JTAG/SWD debuggers, logic analyzers, oscilloscopes, and systematic debugging strategies.
Embedded Systems Testing: Unit, Integration, and System Testing
Learn the three levels of embedded systems testing: unit testing with mocks, integration testing on hardware, and system testing. Covers frameworks, strategies, and the testing… Read More »Embedded Systems Testing: Unit, Integration, and System Testing
