Miro Samek introduces the concepts of state and finite state machines, explaining how they prevent spaghetti code in event-driven systems.
This lesson starts a new segment about STATE MACHINES. The lesson starts with the biggest challenge of event-driven programming, which is preserving the context from one event to the next. You'll see how the usual improvised context management leads to "spaghetti code". Next, you'll see a different approach, in which you capture only the "relevant history" of the system and how this leads to the concepts of "State" and "State Machine". You'll also learn the basic elements of state diagrams, and you'll see how to design a state machine diagram for the "Blinky-Button" example. Finally, you'll see how state machines complement the Active-Object design pattern, and you go through the experience of coding a state machine in C. ------- Resources: Companion web page for this video course: state-machine.com/quickstart GitHub repository for projects for this video course: github.com/QuantumLeaps/modern-embedded-programming-course Freeware QM modeling tool download: github.com/QuantumLeaps/qm/releases Transcript of this lesson: state-machine.com/course/lesson35.txt Music credits: The background music comes from: bensound.com/royalty-free-music/track/straightWhat people say.
