ElenixOS Bubble App Layout Tutorial Published on LVGL Blog
· One min read
A step-by-step tutorial on recreating the WatchOS-style bubble app layout from ElenixOS has been published on the LVGL official blog.
The article covers the complete technical path to replicating the watchOS bubble grid interface from scratch, including:
- Staggered honeycomb layout algorithm: index-to-row/column mapping, dynamic vertical centering
- Distance-field-driven scaling: full size in the center zone, smooth transition toward edges
- Edge compaction and translation compensation: preventing sparse appearance at screen boundaries
- Input state machine: distinguishing taps from drags to avoid false triggers
- Physics engine: damped spring recentering, inertial scrolling, step snapping
- Press animation: local deformation rather than full-frame transforms
The post includes code snippets and algorithm flowcharts, making it suitable for embedded UI developers who want to dive deep into custom LVGL component development.
