QP real-time event frameworks (RTEFs) provide lightweight, modern, event-driven architecture based on asynchronous Active Objects (Actors) and Hierarchical State Machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing, and unit testing for event-driven embedded software.

This project is now in the research and development stage. It is intended for very small microcontrollers with a single processor and represent simple multithreading kernel what written by C language. Is planning create implementations for AVR8 and STM8, may be. Now it is suspended until better time.

PRTOS is an open-source preemptive real time operating system kernel for embedded applications. It presently supports the AVR and MSP430 architectures. The advantages of PRTOS are: It has the smallest footprint of any true preemptive system: 1.9kB for basic scheduling and task control, 5.1kB with all the features below (AVR '328 / gcc -Os); Only 950 lines of code implement all of the RTOS features (SLOC-L); The system is well documented with a comprehensive manual, well-commented source code, and a test suite demonstrating the features; The system is proven - it has been in use since 1982 with applications in in-vitro medical equipment, process control instrumentation and industrial machinery; PRTOS is released by Cleveland Engineering Design, LLC - developer of the CoRTOS cooperative RTOS https://sourceforge.net/projects/cortos-simple/ and the CTREE analysis tool https://sourceforge.net/projects/ctree-graphic-tree-generator/ Commercial licensing is available

Simplest of possible kernel for iterative time division multithreading on smallest AVR boards Arduino. This is a small and adapted part of the future "Like OS".

AvRtos is a small, preemtive, priority based real time operating system for Atmel AVR and ARM microcontrollers. It was written in C. AvRtos provides message queues and semaphores for task synchronization. It uses a static memory allocation scheme. AvRtos is nearly the smallest RTOS out there. Even pico]OS is much bigger. AvRtos can be compiled using gcc compiler. There is a AvrStudio 4 and Eclipse project file to get the example code working very quickly.

LinK+ IDE is a simple IDE for Linux Kernel Developers and Lovers. It is based on Eclipse IDE customized for Linux kernel programming. It reduces the development time and executes code in an elegant fashion. This IDE supports Linux kernel configuration, compilation & emulation, system call development and device driver development. LinK+ IDE includes various templates in the category of character, block and network device driver subsystems for device driver development. It includes various bus infrastructure templates and also provides Linux device driver code completion, code assistance & code navigation for developers. ...

... - How to enter GUI? A: startx [enter] - Known issues? A: A little unstable because of memory management. If it happens, just restart it. - Can I get the source code? A: https://svn.code.sf.net/p/mayax/code (SVN) The entire development environment is zipped into Downloads/devenv.zip. Enjoy! - Can I join? A: For me, Mayax is a one-year project. I don't think I can do further development since I have no time. If you are interesting about its development, just drop me an email at Yang.Dongbin@gmx.com. ...

...I have been somewhat worried about the number of downloads taking place, so I must point out, in no way can this system be used (yet), it's an exploratory project and while it does have some graphics and other bits, only the code at the moment is useful for anyone. Feel free to look at the code (or run iso in VirtualBox) and feel free to join in.

Open Embedded Real Time Operating System. Widely and graphically configurable from a very small non-preemtive OS up to a fully featured pre-emptive system. First target is to cover 8-bit AVR microncotroller's family with GCC - AVR compiler.
