Code generator to build modern and robust event-driven embedded real-time systems based on hierarchical state machines created with UML tools like Enterprise Architect, UModel, Magic Draw, Papyrus, Cadifra., StateSmith is a cross platform, free/open source tool for generating state machines in multiple programming languages. The generated code is human readable, has zero dependencies and is suitable for use with tiny bare metal microcontrollers, video games, apps, web, computers, Stateflow ® charts describe complex system behavior by using hierarchical finite state machine (FSM) theory, flow diagram notation, and state transition diagrams. You can use a Stateflow chart to model a finite state machine or complex control algorithm for an ASIC or FPGA., Hierarchical State Machines (HSMs) A Hierarchical State Machine (HSM) is a Finite State Machine (FSM), but with super powers! Let's add a few more states to our design to make it a smart lightbulb and see the MASSIVE difference a HSM can make., QM (QP Modeler) is a freeware Model-Based Design (MBD) and automatic code generation tool for real-time embedded software in C or C++ based on Hierarchical State Machines↑ (UML Statecharts) and the event-driven QP Real-Time Event Frameworks (RTEFs)↑., Sinelabore RT generates readable and maintainable code from hierarchical UML state machines. With its unique features and the C code generator the tool covers well the requirements of embedded real-time and low power application developers..
