- Drop "Claude" prefix from titles, center all three
- Replace verbose "Current Session" / "Current Week" labels with rounded
pills above the bar; reset countdown moves below the bar
- Extend bar to fill panel inner width (was 8px short)
- Symmetric vertical pill placement within panel
- Spinner: per-frame hold times + ping-pong indexing, modeled on
Claude Code's Cavalry triangle oscillator (turn-around frames hold
~2x longer)
- Bottom spinner re-centered between weekly panel and screen edge
- screenshot.sh: 480x320 -> 480x480 for the new panel
- CLAUDE.md: document screenshot.sh + temporary boot-screen swap as
the standard self-QA workflow for UI changes
- Cache invalidation: drop ~/.config/claude-usage-monitor/ble-address and remove
the dead MAC from bluez on connect failure, so swapping ESP boards no longer
pins the daemon to a stale factory MAC
- Scan robustness: pick first matching candidate (head -1), sanity-check cached
content for valid MAC format, handle multiple Claude Controllers in bluez
- 5s tick + 60s poll: inner loop wakes every 5s for fast disconnect detection
while keeping Anthropic API cadence at one minute
- Refresh-request channel: new GATT characteristic ...0004 NOTIFY, firmware
fires once in onSubscribe when has_received_data is false; daemon subscribes
via setsid'd dbus-monitor pipeline (process group cleanup avoids the
bash-wait-on-job hang we hit on disconnect)

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).
