Modern Embedded Programming with Hierarchical State Machines and Active Objects
Perhaps you’ve heard about hierarchical state machines (UML statecharts), modeling tools and automatic code generation, but have never tried them or seen them used in practice.
This presentation will show you, step-by-step, the process of designing and implementing a fun “Fly ‘n’ Shoot” game to run on an embedded ARM Cortex-M board as well as on your PC.
Specifically, you will see how to partition a problem into loosely coupled, event-driven components called active objects and then how to design interactions among them using sequence diagrams.
Next, you will see how to elaborate the internal behavior of identified active objects with modern hierarchical state machines.And finally, you will see how the state machines are implemented in C and how this code can be generated automatically.The session will utilize hands-on demonstrations using EFM32 Pearl-Gecko ARM Cortex-M4 board, the QP/C real-time embedded framework and the QM modeling and code-generation tool.
