onEmbedded

onEmbedded is a modular software framework intended for building applications on resource-constrained embedded devices. It provides a lightweight runtime, a hardware abstraction layer, and a collection of reusable components to support real-time, deterministic operation while keeping memory usage low. The project aims to simplify development for embedded applications by offering a consistent programming model across different hardware platforms.

The architecture centers on a small, event-driven runtime, a modular component system, and a pluggable driver interface. Components can be developed and tested in isolation and wired together at build time or run time where the platform allows. The hardware abstraction layer decouples application logic from device specifics, enabling portability across multiple microcontrollers and SoCs. The framework emphasizes predictable timing, low footprint, and safe resource management, employing static configuration, clear ownership rules, and optional memory pools.

Programming model and components: Developers implement defined interfaces that describe services such as sensing, actuation, communication, and storage. The framework provides common services for logging, configuration management, and inter-component communication, reducing boilerplate in embedded projects.

Platform support and ecosystem: onEmbedded targets common embedded platforms used in IoT devices, industrial controllers, and robotics. The ecosystem favors small footprints, incremental updates, and straightforward testing. Documentation and examples cover getting started, component development, and debugging.

Development and licensing: The project is community-driven with contributions from individuals and organizations. Licensing terms are defined per module or component and may vary across the ecosystem.
