Lightweight Communications and Marshalling

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.

Looking for a new maintainer

2022 September - LCM isn't actively updated much these days. It should be considered fairly stable on the platforms it was originally developed on, but new feature development and bug fixes are unlikely. If you are interested in taking over as the project maintainer and steering its direction going forwards, please send a message to Albert.
