SCled

SCled is a software and hardware ecosystem designed to control addressable LED displays and lighting installations. It combines a lightweight cross-platform controller application with firmware and optional companion hardware modules to drive LED strips, panels, and matrix arrays for signage, stage lighting, and interactive art.

The project originated as an effort to simplify pixel-mapped lighting workflows, providing a unified interface for playback, scheduling, and realtime input mapping. SCled supports a range of protocols and hardware interfaces commonly used in LED projects, enabling synchronised color, brightness, and animation across heterogeneous installations.

Key features include a scene and timeline editor for composing animated sequences, realtime input routing from MIDI and OSC sources, pixel mapping utilities for non-rectangular surfaces, and a plugin architecture for third-party extensions. The system is designed to be modular: core controller software runs on desktop and embedded platforms, while optional microcontroller firmware handles low-level timing and power management.

SCled is used in live events, architectural lighting, retail displays, and DIY projects. Its architecture emphasizes low latency, frame-accurate output, and adaptability to varying pixel densities and refresh requirements. Community contributions commonly provide drivers for new chipsets and integrations with media servers.

Documentation typically covers installation, wiring and power considerations, calibration, and best practices for thermal and electrical safety. Licensing and distribution vary by implementation; some components are offered under permissive open-source terms, while others may be proprietary. The project is maintained by a mix of volunteer contributors and commercial vendors offering supported hardware and services.
