Imagine a robot with an all-around bump sensor. The response to the bump sensor activating depends on the previous state of the robot. If it had been going forward, a bump will send it backwards and ...

State machines are a foundation of digital design. Eventually we all reach the point where we need to control our digital algorithm, and we almost always turn to a state machine to do the job. State ...

The interest in state machines started in the 1950s when George Moore and Edward Mealy published seminal papers on formal methods of designing digital circuits, which generate outputs based on the ...

This installment starts a new segment of lessons about state machines. The subject conceptually continues the event-driven theme and is one of my favorites [1,2]. Today, you’ll learn what event-driven ...

Function pointers can be used for a wide variety of applications including the implementation of state machines. Just like any tool, it may not always be appropriate to use function pointers for a ...
