LabWired runs real embedded firmware on a deterministic simulation of microcontrollers (ARM Cortex-M, RISC-V, and ESP32), right inside the conversation. Pick a board, wire up an MCU with sensors, displays, and buses, compile firmware, and run it in an interactive hardware lab you can watch — no physical board required. The same firmware binary that flashes to real silicon runs in the simulator, so results are reproducible enough to debug and to gate CI on. LabWired validates your wiring before it runs, lists the boards and components it supports, compiles firmware from source, and opens a live lab view embedded in ChatGPT where you can see GPIO, serial output, and peripherals respond in real time.
