Lightweight Communications and Marshalling (LCM)

LCM is a set of libraries and tools for message passing and data marshalling, targeted at real-time systems where high-bandwidth and low latency are critical. It provides a publish/subscribe message passing model and automatic marshalling/unmarshalling code generation with bindings for applications in a variety of programming languages.

Roadmap

The LCM project is active again. The current long-term plan is to focus on stability and maintenance patches to fix longstanding issues. Longer term we're open to evolution of LCM to have additional features (as long as backwards compatibility is enforced). We're very open to community feedback and involvement on new features.
