About

Combines a C-based headless LVGL 9.2 simulator with a Node.js MCP server for visual ESP32 UI development feedback. Compiles C code snippets in a headless simulator on Windows, captures PNG screenshots and JSON widget tree data, and returns them through MCP. Supports common ESP32 display resolutions and enables AI assistants to provide immediate visual feedback during UI development without deploying to physical hardware. Requires Visual Studio Build Tools and CMake on Windows.
