C++/Rust WASM

The onboard WiliWASM engine runs C++ and Rust code compiled to WebAssembly, complete with a debugger and a full API — bringing systems-language performance to the FreeWili2 platform without requiring custom toolchains.

FreeWili GUI integrates WASM compilers and debuggers directly, so the entire build-flash-debug cycle stays inside a single application. The headless CM0 Linux also uses the same WASM API to draw to the screen, meaning one consistent interface covers both the microcontroller and the Linux environments.
