The daemon reads the Windows "now playing" media session (WinRT SMTC) and
adds np/nt/na to the BLE payload; the watch shows a play/pause glyph, a
scrolling title, artist and status. Best-effort and token-independent, so
it works even when the rate-limit data is unavailable.
Cyrillic titles: Styrene B has no Cyrillic glyphs, so the title/artist use
new composite fonts (font_styrene_cyr_{28,20}) — Latin from Styrene B,
Cyrillic + typographic punctuation from Montserrat, merged by lv_font_conv.
Latin titles stay on-brand; only Cyrillic falls back to Montserrat.
- daemon: read_now_playing() via winrt-Windows.Media.Control (lazy import,
never raises; PLAYING->1, PAUSED->2, else 0; title/artist truncated,
empty fields omitted)
- firmware: UsageData np_state/np_title/np_artist + parser; the real Now
Playing screen replaces the shared stub (SCREEN_NOWPLAYING)
- fonts: assets/Montserrat-Medium.ttf, font_styrene_cyr_{28,20}.c
- tools: patch_lvgl9_font.py (automates the 4 LVGL 9 font patches),
screenshot_win.py (Windows serial screenshot via pyserial + Pillow)
- README: document Cyrillic composite font generation
Verified on hardware (waveshare_amoled_206): idle state, a live Latin
title (scrolling), and Cyrillic (Prohozhdenie / Dunduk) all render.

- convert_to_c.js: remap the claudepix body color (#CD7F6A) to Anthropic brand
terracotta (#D97757) so the splash creature matches the brand; regenerate
splash_animations.h.
- README: document the 3-second hold-to-pair gesture, drop the now-removed
Bluetooth screen from the screenshots table + prose, and delete the
Bluetooth screenshots (216 + 1.8").

- Extract design tokens to firmware/src/theme.h (THEME_BG, THEME_PANEL,
THEME_TEXT, etc.); ui.cpp aliases COL_* to the THEME_* tokens
- Splash container + canvas COL_EMPTY now use THEME_BG / 0x0000 instead
of the hardcoded 0x0f0f0f / 0x10A2 dark grey
- tools/convert_to_c.js maps "transparent" palette entries to 0x0000
(true black) so regenerated splash_animations.h matches the new bg
- Re-regenerate splash_animations.h
- Convert logo to RGB565A8 (alpha plane) so it composites against any
background — no more grey halo around the upper-left logo on screens
where the bg differs from the previous baked-in 0x18E3 color
Full hardware swap from Panlee SC01 Plus (480×320 IPS) to Waveshare 2.16"
square AMOLED (480×480, CO5300 + CST9220 + AXP2101 + QMI8658). Library
stack moves to Arduino_GFX, SensorLib, XPowersLib on the pioarduino
platform 55.03.38-1 (Arduino Core 3.x).
UI:
- 4 screens (splash, usage, controller, bluetooth) with 3-button physical
navigation: GPIO 0 = prev, AXP PKEY = cycle, GPIO 18 = next.
- IMU-driven 90° auto-rotation. CO5300 can't rotate via MADCTL, so flush
callback does CPU strip-rotation in PARTIAL render mode. Rotation
transitions use AMOLED brightness flash (instant black → redraw → ramp).
- Battery indicator (Lucide icons) in upper-right, RGB565A8 alpha so it
blends over the splash animations.
- USB plugged/unplugged auto-switches between Usage and Controller
screens (suppressed while on splash).
- Fonts and icons re-scaled ~1.9× for the higher-DPI panel; 20px margins
to clear rounded corners.
Splash:
- 13 × 20×20 pixel-art creature animations sourced from
claudepix.vercel.app via tools/scrape_claudepix.js (scraper handles
both PRESET creature-engine and standalone FRAMES+PAL formats).
tools/convert_to_c.js emits firmware/src/splash_animations.h.
Attribution preserved in README and the generated header.
Tooling:
- tools/png_to_lvgl.js converts alpha PNGs to LVGL RGB565A8 (planar
layout, with --tint to colorize Lucide black-on-transparent sources).
- tools/scrape_claudepix.js, tools/convert_to_c.js for the splash
pipeline.
Docs:
- New worktree CLAUDE.md with hardware pin map, file inventory, build
commands, and the 8 critical gotchas (CO5300 rotation, OPI PSRAM,
pioarduino requirement, LVGL 9 font patching, centralized touch read,
even-aligned flush regions, touch swap/mirror values, RGB565A8 layout).
