summary

WebAssembly on microcontrollers gains a lightweight interrupt mechanism and language glue implemented in the WARDuino VM so Rust and AssemblyScript code can call IO primitives (HTTP, MQTT) using buffer-based string passing. The team formalizes the extension, runs it on an ESP32, and ships a smart-lamp demo that toggles an LED via button or MQTT. Measured interrupt latency is 336 microseconds (C: 20 µs); overall execution is ~465× slower than native but 10× faster than Espruino.
