FSM data structure design

syuga

Hi Folks,

I want to write an FSM which starts with an idle state and moves from one state to another based on some event. I am not familiar with coding of FSM and google didn't help. Appreciate if someone could post the C data structure that could be used for the same.

Thanks,

The website [link=http://www.state-machine.com]www.state-machine.com[/link] contains a lot of resources about using state machines in embedded systems. Among others, you can download open source QP frameworks that enable designing and implementing systems of concurrent hierarchical state machines (UML statecharts) directly in readable and maintainable C or C++ without big design automation tools.

If you do not want to hand-code the state machine, there are graphical tools to draw [link=http://www.mathworks.com/products/stateflow/]state machines[/link] which can animate and generate C/C++ code automatically. One such graphical tool is Stateflow.

See some videos to learn more about the tool at the link below:
