New screens/weather_icons.py: vector icons drawn with PIL primitives using
the panel's actual 6-color palette (black/white/yellow/red/blue/green, from
epd4in0e's own getbuffer() quantization table) -- sun with rays, line-art
clouds, blue rain/snow, yellow lightning bolt, fog bands. Replaces the old
monochrome unicode-glyph approach entirely (also sidesteps font coverage
gaps -- that's what caused the earlier tofu-box bug).
Forecast row given significantly more vertical space per request. Caught
two real bugs while building this:
- Current-conditions block height was guessed independently of the space
allocated to it, so it overflowed into the forecast row for real content.
Now derives the space it needs from actual measured text/icon size
instead of assuming both fit.
- `scale * 0.045 if has_forecast else 0.05` -- conditional-expression
precedence bug, silently evaluated to a bare 0.05 (not scale * 0.05) in
the else branch, crashing font loading with size=0 when forecast is
empty. Only surfaced by testing that specific case.
- Sun icon's rays extended past the nominal icon_size box used for layout
math, throckwing off vertical centering when no forecast is shown.
positionMs changes every poll (~20s), so the old live progress bar/elapsed
time forced a full flash constantly, even mid-song -- this panel has no
partial refresh, so there's no way to show real progress without that.
Now it's an outline + total length only, driven by nothing that changes
while the same track keeps playing. Verified the rendered image is
byte-identical across different positionMs values for the same track.
Also dropped elapsed/elapsed_text/progress_pct from the track dict
entirely now that nothing renders them.
Two separate imbalances:
- Cover art was top-aligned when width-constrained (landscape, cover_size
capped by width*0.5), leaving dead space below it instead of centering
in the available height.
- The text column always started drawing at the very top and let the
source line's bottom-pin create a big empty gap for tracks with
short/sparse metadata -- looked top-heavy and unbalanced.
Text column is now built as (height, draw_fn) pairs first so the total
height is known before committing to a starting y, then centered in the
space above the reserved source-line area.
- scheduler: "Show X now" was a true one-shot -- reverted on the very next
5s tick, causing the flash-to-X-then-flash-back-to-clock behavior. Now
pins for 5 minutes (still preemptable by Navidrome priority, which stays
authoritative). Added a "Resume automatic" action/button and status
display showing what's pinned and until when.
- weather: daily forecast strip (3/5/7 days, selectable in settings) below
current conditions, via Open-Meteo's daily= params in the same request.
Fixed a bad symbol choice along the way -- DejaVu Sans has no glyph for
the partly-cloudy emoji, was rendering as a tofu box; swapped to the
plain cloud symbol, verified glyph coverage for the whole WMO code table.
New screen alongside clock/weather/navidrome. Upload goes through the web
UI (validated with PIL before accepting, stored under web/static/uploads/,
gitignored), or point it at a URL re-fetched every 30 minutes. Cover/contain
fit modes (new fit_cover/fit_contain helpers in render_utils.py, generalized
from the square-only cover-art cropping already used by the Navidrome
screen), plus the same contrast-boost/grayscale options that screen has.
- Panel is mounted sideways: render landscape (600x400), rotate to the
panel's native portrait orientation right before writing to hardware.
- Web UI: card-based layout, dark mode, active nav highlighting, save
confirmation toasts, error banners.
- Rotation: separate enabled/disabled toggle (off pins to the first screen
in the list) and the interval is now in minutes instead of raw seconds.
Migrates existing config.json from the old interval_seconds field.
- Weather: type a city name instead of hunting down coordinates, resolved
via Open-Meteo's free geocoding API. Manual lat/long still available as
a fallback.
Was importing 'waveshare_epd' as a top-level package, but it's nested
under display/waveshare_epd/ -- caused ModuleNotFoundError on the Pi
since only display/ is on sys.path via main.py's imports, not
display/waveshare_epd/ itself. Verified the corrected import resolves
by exercising it directly; the only error left is the driver's own
platform check falling through to its Jetson Nano path on this non-Pi
dev machine, which is expected here and won't happen on the real
Raspberry Pi (it checks /proc/cpuinfo for "Raspberry").
