QP Tutorials

The QP™ Tutorials present an example project implemented entirely with the QP™ event-driven platform using UML state machines and the event-driven paradigm. The example application is an interactive "Fly 'n' Shoot"-type game, which you can execute on any PC or on an inexpensive Cortex-M3 development kit.

QP Development Kits

QDKs

The QP™ baseline code usually needs to be adapted to various operating systems, microprocessors, and compilers. Adapting the QP software is called porting and QP™ has been designed from ground up to make the porting easy. A large and steadily growing number of QP Development Kits (QDKs) for popular operating systems and processors are available for download.
