About AP/C
|
||
|
|
==========
|
||
|
|
QP/C (Quantum Platform in C) is a lightweight, open source software framework
|
||
|
|
for building responsive and modular real-time embedded applications as
|
||
|
|
systems of cooperating, 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 commercially licensable.
|
||
|
|
|
||
|
|
All QP frameworks can run on bare-metal single-chip microcontrollers,
|
||
|
|
completely replacing a traditional Real-Time Operating System (RTOS).
|
||
|
|
Ports and ready-to-use examples are provided for major CPU families.
|
||
|
|
|
||
|
|
QP/C can also work with many traditional RTOSes and desktop OSes (such as
|
||
|
|
Windows, Linux including embedded Linux).
|
||
|
|
|
||
|
|
The behavior of active objects is specified in QP by means of hierarchical
|
||
|
|
state machines (UML statecharts). The frameworks support manual coding of
|
||
|
|
UML state machines in C or C++ as well as fully automatic code generation
|
||
|
|
by means of the free graphical QM modeling tool.
|
||
|
|
|
||
|
|
The QP frameworks are used in millions of products worldwide in aerospace,
|
||
|
|
medical devices, consumer electronics, wired and wireless telecommunications,
|
||
|
|
industrial automation, transportation, robotics, and many more. The QP
|
||
|
|
frameworks and the QM modeling tool receive over 40,000 downloads a year.
|
||
|
|
|
||
|
|
The book, Practical UML Statecharts in C/C++, 2nd Edition provides a detailed
|
||
|
|
design study of the QP frameworks and explains all the related concepts.

Licensing QP/C
|
||
|
|
==============
|
||
|
|
QP/C is licensed under the increasingly popular dual licensing model, 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, in which case you don't use any
|
||
|
|
open source license and you do not violate your policy.
|
||

Open Source Projects:
|
||
|
|
--------------------
|
||
|
|
If you are developing and distributing open source applications under the
|
||
|
|
GNU General Public License (GPL), as published by the Free Software
|
||
|
|
Foundation, then you are free to use the Quantum Leaps software under the
|
||
|
|
GPL version 3 of the License, or (at your option) any later version. Please
|
||
|
|
note that GPL requires that all modifications to the original code as well
|
||
|
|
as your application code (Derivative Works as defined in the Copyright Law)
|
||
|
|
must also be released under the terms of the GPL open source license.
|
||
|
|
|
||
|
|
Closed Source Projects:
|
||
|
|
-----------------------
|
||
|
|
If you are developing and distributing traditional closed source
|
||
|
|
applications, you can purchase one of Quantum Leaps commercial licenses,
|
||
|
|
which are specifically designed for users interested in retaining the
|
||
|
|
proprietary status of their code. All Quantum Leaps commercial licenses
|
||
|
|
expressly supersede the GPL open source license. This means that when you
|
||
|
|
license Quantum Leaps software under a commercial license, you specifically
|
||
|
|
do not use the software under the open source license and therefore you are
|
||
|
|
not subject to any of its terms.
