A Reusable Zbus Based Architecture, Abstracting Core Application...
summary
Plentify ports products to Zephyr and builds a reusable application base using zbus channels for commands and events, splitting functionality into ~5 independent services. zbus gives one-to-many inter-thread messaging with three subscriber types (listener, message subscriber, normal subscriber), improving modularity, testability and reuse. Practical issues include unioned struct payloads hurting type safety, copying large data (images) for subscribers versus pointer ownership and lifetime management, and choosing thread vs listener execution context per service.
