AtlasCube – Layout Editor

🖼️ Layout Editor

⚠️ After a firmware update the built-in layout may have changed. If widgets look misaligned or overlap, use Reset all to restore this version's defaults (this discards your custom positions).

Drag rectangle body to move. Drag orange corner handles to resize. Labels with only x/y (no size) follow font metrics.

Layout presets

Per-wallpaper layout presets mirror the wallpaper's own place on the SD card: /wallpapers/<res>/<category>/name.bin → /wallpapers/layouts/<res>/<category>/name.json (saved with the preset buttons under the live preview). The check scans both that layout and the older flat one, and finds missing wallpapers, invalid JSON and resolution stamps that do not match their directory.

General background

The standard background for screens set to General. When an internet wallpaper is fetched (Internet tab), it replaces this on every General/Internet screen; screens set to a specific SD file keep it.

Wallpaper brightness

🌒 Brightness 100%

Applies to every wallpaper — per-screen SD files and the fetched internet one. Lower it to darken the image so on-screen text stays readable; gradient/solid backgrounds are not affected. 100% = original image.

Upload wallpaper (no assign)

Convert a PNG/JPG to an LVGL RGB565 .bin scaled to the current panel resolution and store it under /wallpapers/<width>x<height> on the SD card — without changing what any screen shows. Assign it later per screen with the 🗂 picker under the live preview.

No file selected

Upload image asset

Convert a PNG/JPG to an LVGL RGB565 .bin and store it on the SD card, then point a widget at it (e.g. a volume-slider Knob image). The image is scaled to the size selected during upload — for a knob, that is its on-screen size. No transparency: the image is a solid rectangle.

Internet wallpaper

The device downloads a photo straight from the selected service (on that service's own terms) and uses it as the screen background, kept in RAM until reboot. A playing radio stream pauses during the download. NASA APOD API links are resolved automatically (DEMO_KEY is rate-limited — a free personal key from api.nasa.gov lifts that).

Auto refresh

Uses the URL above (saved together with the schedule). The wallpaper lives in RAM only, so both auto modes re-fetch it ~30 s after every boot. A playing radio stream is paused for the few seconds of the download.
