QP is a family of lightweight software frameworks for building responsive and modular real-time embedded applications as systems of cooperating, event-driven active objects (actors). The QP family consists of QP/C, QP/C++, and QP-nano frameworks, which are all strictly quality controlled, superbly documented, and commercially licensable. 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 automatic code generation by means of the free QM modeling tool. All QP frameworks can run on bare-metal MCUs, completely replacing a traditional RTOS. Ports and ready-to-use examples are provided for all major CPUs, such as ARM Cortex-M, ARM7/9, MSP430, C28x, C55x, RX, R8C, AVR32, AVRMega, PIC24/dsPIC, as well as Arduino and mbed. QP/C and QP/C++ can also work with a traditional OS/RTOS, such as: POSIX (Linux, QNX), Windows, VxWorks, ThreadX, and uC/OS.
Obix is an object-oriented, portable, open-source programming language, specifically designed to increase the reliability, productivity, and simplicity in software development projects. The aim is to achieve these three important goals through a unique combination of proven and innovative concepts supporting the "Fail fast!" principle.
nwsystest is a simple tool to help test full software systems (written in C or C++) - potentially consisting of multiple applications and threads - in an automated manner. It drives program execution and collects and evaluates results in accordance with textual test description files. Programs can be made testable by calling a few simple library routines to connect to the test server, receive commands from it (effectively replacing the user interface), and transfer results for verification.
TinyIB is a lightweight PHP image board which emulates the functionality of 4chan. If you use MySQL or SQLite, you can use it to create an efficient setup able to handle large amounts of traffic. If you don't use a database, it can store posts as text files for a portable setup capable of running on virtually any PHP host.
