BeeOS Phase 7 Notes

Completed in this phase

Phase 7 adds the first BeeOS asset conversion pipeline.

New files:

tools/convert_icons_for_lvgl.py
beeos/core/asset_build.py
beeos/generated/icons/icon_build_index.json
beeos/generated/icons/bitmap_json/
beeos/generated/icons/lvgl/
beeos/generated/icons/previews/

Why this matters

The desktop simulator can use PNG icons, but the PineTime Pro firmware/LVGL port will need compact generated assets.

Phase 7 creates an intermediate format:

• compact JSON bitmap rows
• packed 1-bit byte buffers
• C header/source files
• preview sheets

Not final LVGL descriptors yet

The generated C files are firmware-friendly icon buffers, not full lv_image_dsc_t declarations yet.

A future phase can wrap these buffers in LVGL-specific image descriptors once the exact LVGL version and color format are chosen.

Next possible phase

Phase 8 should probably add:

• actual LVGL image descriptor export option
• theme export tool
• watch face package runtime
• HiveStore update simulation
• app settings pages
