Lightweight frameworks for building modular real-time embedded software as systems of cooperating, event-driven active objects (actors) and hierarchical state machines.
Free graphical modeling tool for designing and auto-generating production-quality code based on hierarchical state machines and the QP™ actor frameworks.
Live monitoring of QP applications without stopping or significantly slowing down the code.
Free, open source host-based tools for working with the QP™ frameworks, such as: QWIN GUI, qclean, qfsgen, qcalc, etc...
The embedded software industry is in the midst of a major revolution. Tremendous amount of new development lays ahead. This new software needs an actual architecture that is safer, more extensible, and easier to understand than the usual "free-threading" approach of a traditional Real-Time Operating System ( RTOS).
Quantum Leaps' software frameworks and tools provide such a modern, reusable event-driven architecture based on active objects (actors), hierarchical state machines, software tracing, graphical modeling, and automatic code generation.
Welcome to the 21st Century!
QP/CLightweight open source active object (actor) framework in C. Recommended for 16- and 32-bit MCUs with RAM > 1KB, such as ARM Cortex-M.
QP/C++Lightweight open source active object (actor) framework in C++. Recommended for 16- and 32-bit MCUs with RAM > 1KB, such as ARM Cortex-M.
QP-nanoUltra-lightweight open source active object (actor) framework in C. Recommended for low-end 8- and 16-bit MCUs with RAM <1KB, such as MSP430 and AVR.
QMFreeware, "low-ceremony" graphical modeling tool and automatic code generator based on hierarchical state machines (UML statecharts) and the QP frameworks. Available for Windows, Linux, and Mac OSX.
QtoolsCollection of various open source host-based tools for QP™, including:
QSPY Software Tracing for live monitoring of QP/C or QP/C++ applications 
QWIN GUI for prototyping embedded software on Windows (dual-targeting) 
QP 5.6.1 adds new preemptive, blocking RTOS kernel called QXK
QP/C/C++ and QSPY 5.5.x take software tracing to a new level
