View QP/C Revision History at: https://state-machine.com/qpc/history.html --------------------------------------------------------------------------- # About QP/C QP/C (Quantum Platform in C) is a lightweight, open source software framework/RTOS for building reactvie real-time embedded applications as systems of cooperating, event-driven active objects (actors). The QP/C framework is a member of a larger [QP] family consisting of QP/C, QP/C++, and QP-nano frameworks, which are all strictly quality controlled, thoroughly documented, and commercially licensable. ## Safer Model of Concurrency The [QP] framework family is based on the [Active Object] (**actor**) design pattern, which inherently supports and automatically enforces the following best practices of concurrent programming: - Keep data isolated and bound to active objects' threads. Threads should hide (**encapsulate**) their private data and other resources, and not share them with the rest of the system. - Communicate among active object threads **asynchronously** via event objects. Using asynchronous events keeps the threads running truly independently, **without blocking** on each other. - Active object threads should spend their lifetime responding to incoming events, so their mainline should consist of an **event-loop** that handles events one at a time (to completion), thus avoiding any concurrency hazards within an active object thread itself. This architecture is generally **safer**, more responsive and easier to understand and maintain than the shared-state concurrency of a conventional RTOS. It also provides higher level of abstraction and the right abstractions to effectively apply **modeling** and **code generation** to deeply embedded real-time systems. ## Hierarchical State Machines 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. ## Built-in Real-Time Kernels The QP/C framework can run on bare-metal single-chip microcontrollers, completely replacing a traditional RTOS. The framework contains a selection of **built-in real-time kernels**, such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the preemptive, blocking QXK kernel that provides all the features you might expect from a traditional RTOS. Native QP ports and ready-to-use examples are provided for major CPUs, such as ARM Cortex-M (M0/M0+/M3/M4/M7). ## Traditional RTOS/OS QP/C can also work with a traditional RTOS, such as ThreadX, embOS, uC/OS-II and TI-RTOS, as well as with (embedded) Linux (POSIX) and Windows. ## Maturity With 60,000 downloads a year, the [QP] family is the most popular such solution on the embedded software market. It provides a modern, reusable architecture for embedded applications, which combines the active-object model of concurrency with hierarchical state machines. --------------------------------------------------------------------------- # Getting Started with QP/C The following "Getting Started with QP/C" guide provides step-by-step instructions on how to download, install, and get started with QP/C quickly: https://state-machine.com/doc/AN_Getting_Started_with_QPC.pdf The guide also contains a tutorial, in which you build a simple "Blinky" application. > **NOTE:** QP/C can be unzipped anywhere in your file system, but the recommended location is `C:\qp\qpc` on Windows and `~/qp/qpc` on Linux/MacOS. --------------------------------------------------------------------------- # QP/C Licensing QP/C is licensed under the increasingly popular [dual licensing model](https://state-machine.com/licensing), in which both the open source software distribution mechanism and traditional closed source software distribution models are combined. > **NOTE:** If your company has a policy forbidding open source in your product, all QP frameworks can be [licensed commercially](https://state-machine.com/licensing), in which case you don't use any open source license and you do not violate your policy. --------------------------------------------------------------------------- # QP/C Documentation The **QP/C Manual** is located online at: https://state-machine.com/qpc --------------------------------------------------------------------------- # How to get help? - [Free Support Forum](https://sourceforge.net/p/qpc/discussion/668726) - [Bug Reports](https://sourceforge.net/p/qpc/bugs/) - [Feature Requests](https://sourceforge.net/p/qpc/feature-requests/) - [Quantum Leaps website](https://state-machine.com) - [Quantum Leaps licensing](https://state-machine.com/licensing) - [info@state-machine.com](mailto:info@state-machine.com) [QP]: [QM]: [Active Object]: [Hierarchical State Machines]:
