Quantum Leaps / qp Featured

QP is an event-driven, RTOS-like, active object framework for microcontrollers, such as mbed. The QP framework provides thread-safe execution of active objects (concurrent state machines) and support both manual and automatic coding of UML statecharts in readable, production-quality C or C++. Automatic code generation of QP code is supported by the free QM modeling tool.

QP/C++ (Quantum Platform in C++) is a lightweight, open source active object (actor) framework for building responsive and modular real-time embedded applications as systems of asynchronous event-driven active objects (actors). The QP/C++ framework is a member of a larger family consisting of QP/C++, QP/C, and QP-nano frameworks, which are all strictly quality controlled, thoroughly documented, and available under GPLv3 with a special Exception for mbed (see http://www.state-machine.com/licensing/QP-mbed_GPL_Exception.txt).

The behavior of active objects is specified in QP/C++ by means of hierarchical state machines (UML statecharts). The framework supports manual coding of UML state machines in C++ as well as automatic code generation by means of the free QM modeling tool (http://www.state-machine.com/qm).

Please see the "QP/C++ Reference Manual" (http://www.state-machine.com/qpcpp) for more information.
