Most embedded systems are reactive by nature. They measure certain properties of their environment with sensors and react on changes. For example, they display something, move a motor, or send a ...

To the uninitiated the words ‘State machine’ sound like something scarily big and complex. They aren’t (necessarily) and can be quite useful. In fact, state machines are no physical machines but a ...

Raindrops on roses, and whiskers on kittens. They’re ok, but state machines are absolutely on our short list of favorite things. There are probably as many ways to implement a state machine as there ...

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 ...

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 ...

A recent EDN article dealt with a number of programming tips for embedded microcontrollers. One of those tips, using state machines, is a programming approach that is especially useful, yet probably ...
