This article explains how to implement finite state machines in C using three classic approaches—switch‑case, table‑driven, and function‑pointer—detailing their structures, code examples, trade‑offs, and safety considerations for embedded and general‑purpose software development.
This article explains three core ways to implement finite state machines in C—switch‑case, table‑driven, and function‑pointer approaches—detailing their structures, code examples, advantages, pitfalls, and how they relate to extended and hierarchical state machines.
This article shows how C can achieve object‑oriented‑style design by using structs to model classes and function pointers as methods, providing concrete code examples such as a linked‑list implementation, interface definition, and test harness to illustrate the technique.
This article explains how to implement finite state machines in C using three approaches—switch‑case, table‑driven, and function‑pointer—detailing their structures, code examples, trade‑offs, and extensions such as compressed tables and hierarchical state machines for robust embedded systems.
This guide explains how to manipulate hardware registers, use function pointers, and perform bit‑level operations in C to control NAND Flash on S3C2410/S3C2440 platforms, providing concrete macro definitions, struct layouts, and initialization code for portable embedded development.
This article explains how C/C++ function pointers work, demonstrates their compiled address, shows why they lack context, introduces a closure struct to bundle code with data, and relates this pattern to C++'s std::function for storing callables with captured environment.
This article explains what a finite state machine (FSM) is, where it is commonly used, and walks through three C implementations—plain if/else, switch‑case, and a function‑pointer table—highlighting their advantages, drawbacks, and providing complete code examples.
