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.

UFFS: Ultra-low-cost Flash File System, designed for NAND flash working in embedded system. UFFS typically consumes less then 200K ram for 1Gb(page 512)/4Gb(page 2K) NAND flash. It supports direct flash interface, works with or without OS.
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, modular, microkernel-based operating system under development for i386. The first goal is to support 32-bit DOS protected mode applications made with DJGPP as well as native applications.
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.
CooCox CoOS is an Embedded RTOS specially for ARM Cortex-M3. It is a real-time multitask kernel which accords with CMSIS ( Cortex Microcontroller Software Interface Standard ). It is a free and open real-time Operating System.

The CyaSSL embedded SSL library (Now known as wolfSSL) is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. It works seamlessly in desktop, enterprise, and cloud environments as well. wolfSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, OCSP and CRL support, is backed by the robust wolfCrypt cryptography library, and much more. wolfSSL relies on the soon-to-be FIPS 140-2 validated wolfCrypt library for all cryptographic functionality.
