Vision UI is a small list-based UI framework for embedded displays. It provides a menu tree, animated selection and scrolling, notifications, alerts, and a driver abstraction so the same UI logic can run in a desktop simulator or on device-specific backends. The core library is platform independent and can be integrated with any backend that implements the drawing and input driver interface.
The repository includes an simulator as one example backend for prototyping menus and custom full-screen scenes before integrating the library into firmware.
- Hierarchical list navigation with title rows, switches, sliders, icon items, and custom user-rendered scenes.
- Animated selector, camera tracking, text scrolling, enter/exit transitions, notifications, and alerts.
- Thin driver interface for input, text measurement, drawing primitives, clipping, and buffer submission.
- Configurable layout and timing constants in
include/vision_ui_config.h, with a tuning guide indocs/config.md. - Platform-independent core with pluggable backends.
- Example backends for local simulation and embedded targets.
