QP Active Object Frameworks provide a robust solution for building event-driven systems, making concurrency and real-time application development more manageable for engineers.

QP Active Object Frameworks is a family of event-driven, RTOS-like, active object frameworks for microcontrollers. The QP frameworks provide 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. The QP family consists of QP/C, QP/C++, and QP-nano frameworks, which are all professionally developed, strictly quality controlled, well documented, MISRA-compliant, and commercially licensable. All QP frameworks can run on "bare metal", completely replacing a traditional RTOS. Ports and ready-to-use examples are provided for Cortex-M3, Cortex-M4, Cortex-M0, RX600, MSP430, C28x, C55x, AVR, ARM7, ARM9, ColdFire, PIC24, dsPIC, M16C/R8C, H8, HC08, 8051, Arduino, and mbed. QP/C and QP/C++ can also work with a traditional (RT)OS such as POSIX (Linux, QNX), Windows, VxWorks, ThreadX, uC/OS, or FreeRTOS.
