Learn the differences between NTC and PTC thermistors, how they work, their applications in embedded systems, and how to read an NTC thermistor with a microcontroller using a voltage divider and ADC.
Learn the Open/Closed Principle with practical C examples using function pointers. See how to extend behavior without modifying existing, tested code.
Learn power consumption fundamentals for embedded systems: where power goes, how to measure it, and key strategies to extend battery life including sleep modes, clock scaling, and power gating.
Learn how to use a config.h header file to enable and disable features at compile time in embedded C projects. Covers board variants, debug logging, build system integration, and compile-time assertions.
Learn the Single Responsibility Principle with practical C examples. See how splitting a module into focused responsibilities makes code easier to maintain, test, and reuse.
Learn how to create and use static libraries (.a) and dynamic shared libraries (.so/.dll) in C. Covers compilation steps, linking, runtime loading with dlopen, and when to use each type in embedded systems.
Learn how unions in C help with packing and unpacking data in embedded systems. See practical examples of byte conversion, protocol parsing, and hardware register access using unions.
Learn the key software quality attributes: maintainability, reliability, testability, readability, reusability, modularity, and more. Each term explained with simple C examples.
Learn how to use malloc, calloc, realloc, and free in C for dynamic memory allocation. Understand stack vs heap, common pitfalls like memory leaks and dangling pointers, and best practices for embedded systems.
Learn how to organize your C code into separate header (.h) and source (.c) files. Covers include guards, module patterns, and best practices for embedded systems projects.
