Combining Zephyr & C++20 to Build Safe, Low-footprint, Event-based Applicati...
summary
Zephyr plus C++20 produce an event-based framework that avoids heap allocations, maps events to irq/workqueue/thread contexts, and compiles down small: notify paths are about 30 instructions and example listeners are ~16–36 bytes; a demo charger runs in ~16 kB RAM with GPIO timers, relays, Modbus and hierarchical state machines. Asynchronous delivery uses a ring buffer plus Zephyr workqueue (event stream queue), and synchronous delivery unrolls subscriber calls at compile time.
