Wendy Lite

Wendy Lite is a WebAssembly (WASM) runtime firmware for ESP32-C6 microcontrollers. It enables developers to write apps in C, Rust, Swift, Zig, TypeScript, or WAT, compile them to WASM, and run them on the device with full hardware access.

Key Concepts

• WAMR Runtime: Uses WebAssembly Micro Runtime to execute WASM binaries
• Host Imports: WASM apps import functions from the "wendy" module to access hardware
• Callback System: Async events (GPIO interrupts, timers, BLE) dispatched via exported wendy_handle_callback
• Flash Persistence: WASM binaries stored in flash partition wasm_a (2MB), auto-loaded on boot
• Multi-language: Apps can be written in C, Rust, Swift 6.0+, Zig, TypeScript, or raw WAT
