Market leading real time kernel for 35+ microcontroller architectures
FreeRTOS is a market leading RTOS kernel from Amazon Web Services that supports more than 35 architectures and was downloaded once every 3 minutes during 2016. With millions of deployments in all imaginable market sectors (from toys to aircraft), the FreeRTOS kernel is trusted because it is professionally developed, strictly quality controlled, robust, supported, free to use in commercial products without a requirement to expose proprietary source code, and has no IP infringement risk. Amazon Web Services provides a highly reliable, scalable, low-cost cloud infrastructure platform that powers hundreds of thousands of businesses in 190 countries around the world. In 2015 AWS added specific Internet of Things (IoT) capabilities, and now offers Amazon FreeRTOS to help users securely connect their MCU devices to the cloud.

Real-time frameworks/RTOS based on active objects & state machines
Real-time frameworks/RTOS for building responsive and modular real-time embedded software as systems of active objects (concurrent state machines). 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 (a.k.a. actors) 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 major embedded CPUs, such as ARM Cortex-M, ARM7/9, MSP430, as well as Arduino and mbed. QP/C and QP/C++ can also work with a traditional RTOS/OS, such as ThreadX, FreeRTOS, embOS, and uC/OS-II as well as Linux (POSIX), Windows.
State machine framework for reactive embedded systems
RKH is a generic, flexible, modular, highly portable, ANSI-C compliant, and open-source development tool for implementing hierarchical state machines based on modern state machine concepts. This modern techniques are used to give an abstract description of the dynamic behavior of a system in a substantial manner. The RKH not implements neither entire UML specs. nor entire Statechart specs. Instead, the RKH intention is to support just enough basic concepts of that powerful tools to facilitate the reactive-system modeling holding a solid, and efficient implementation. Broadly speaking, the RKH implementation has been designed from the ground up to be used in 8-bits platforms but can be easily adapted to 16 or 32-bits platforms.
Real time embedded multi-thread kernel
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. In near time is planning create implementations for AVR and STM8.
Debug Facility for Real-Time issues
For C (and CPP obviously): Include a fast and tiny RAM-tracing feature for Real-Time (RT) debugging purposes. >> ONLY FOR DEBUGGING << Very much faster than printf-debugging, which may result in unforseen results in an RT environement.
Simplest kernel for cooperative multithreading
Simplest of possible ways to multithreading on the smallest microcontrollers. This project is demonstration the programming technique of the multithreading with polling the system state. Published code debugged and ready to use in your projects.
Community-driven variant of TI's bare metal development support tools
This is the community driven variant of StarterWare(tm) 2.0.x by Texas Instruments, a collection of example source codes, headers, and basic implementations for AM335X-based hardware (like the BeagleBone Black, the PocketBeagle or the OSD335x SiP). The aim of this project is to add features and functionalities faster than TI is able to do that and to get a high-quality package for easy bare metal programming on such Sitara-based devices.
