Replaces the build-flag-driven #ifdef sprawl (~30 blocks across 6 files)
with a small HAL in firmware/src/hal/ and per-board folders under
firmware/src/boards/. Shared code (main.cpp, ui.cpp, splash.cpp) no
longer contains a single `#ifdef BOARD_*` — optional features are
guarded by BoardCaps (runtime) and BOARD_HAS_* macros (compile-time,
inside the board's own files).
Why: lets community contributors port to new ESP32 + AMOLED + touch
combos by dropping in a boards/<name>/ folder + a PlatformIO env,
without touching shared files. See docs/porting/adding-a-board.md.
Highlights:
- New HAL: display_hal, touch_hal, input_hal, power_hal, imu_hal,
board_caps. Each board provides display.cpp, touch.cpp, input.cpp,
power.cpp, imu.cpp, caps.cpp, board_init.cpp + private hardware
drivers (e.g. io_expander.{h,cpp} on AMOLED-1.8).
- PlatformIO build_src_filter selects each board's folder per env.
- ui.cpp picks fonts and layout from board_caps() via compute_layout()
with screen-height breakpoints (>= 460 → large, else compact).
- splash.cpp computes CELL = min(W,H)/20 — responsive instead of two
hardcoded values.
- idle.cpp (from #24) rewired through display_hal + power_hal — no
longer depends on the deleted display_cfg.h / power.h.
- power_hal gains power_hal_is_vbus_in() for idle's
IDLE_SLEEP_WHEN_CHARGING gate.
- boards/template/ + docs/porting/{adding-a-board,hal-contract,
capability-flags}.md to bootstrap new ports.
- display_cfg.h, power.{h,cpp}, imu.{h,cpp}, io_expander.{h,cpp}
deleted from src/ root (moved into boards/<name>/ or hal/).
Verification: both `pio run -e waveshare_amoled_216` and
`pio run -e waveshare_amoled_18` succeed unchanged.

Cherry-picks the macOS-specific pieces from PR #5: Python daemon using
bleak (CoreBluetooth backend), LaunchAgent template, flash-mac.sh, and
install-mac.sh. Token is read from the macOS Keychain ("Claude
Code-credentials" service); Linux behavior is unchanged. README split
into "macOS installation" and "Linux installation" sections with
parallel Flash / Pair / Install subsections.

GitHub's clickable-thumbnail trick worked but was awkward; a 500x500
12fps GIF renders inline everywhere. Drop the now-unused thumbnail.

GitHub strips relative src on <video> tags, so swap to an image link
pointing at the raw mp4. Extracted a frame for the thumbnail so the
two demo cells aren't visually identical.

Replace the 480x320 Panlee-era usage/bluetooth/controller PNGs with
fresh 480x480 captures of the current UI (Usage, Bluetooth, Splash).
Drop the Controller screen column entirely — that screen was removed
when buttons took over its shortcuts.
README cleanup: daemon poll cadence corrected to 60s, splash mood-
group + auto-rotation behaviour documented, "tap the logo to cycle"
replaced with the actual middle-button gesture, Lucide section
rewritten to point at tools/png_to_lvgl.js instead of the dead inline
Python+inkscape recipe, and intro line drops "touch controller" since
touch only toggles splash now. demo.gif flagged as stale (recapture is
a hardware task).
UX overhaul:
- Drop the Controller screen entirely (touch zones, swipe gestures, HID
gesture engine, four icon arrays, hand icon)
- Two persistent screens (Usage, Bluetooth) cycled by the middle PWR
button; splash becomes a touch-toggled welcome animation
- Left button (GPIO 0): hold to send Space (Claude Code voice-mode PTT)
- Right button (GPIO 18): press to send Shift+Tab (mode toggle)
- Middle button on splash cycles animations instead of screens
- Remove USB plug/unplug auto-switch (Controller was the unplug target)
- Hide battery indicator on splash when in LOW state — it's noisy over
the pixel-art animations
Implementation:
- Delete firmware/src/hid.{cpp,h} and touch.{cpp,h}; their roles fold
into main.cpp button handlers and LVGL CLICKED events respectively
- splash_get_root() exposes the splash container so ui.cpp can attach
a click handler for the dismiss-on-tap behavior
- Tap detection uses LVGL's built-in LV_EVENT_CLICKED with event
bubbling on the inner panels — debouncing is handled by LVGL
- On Bluetooth screen, only the Reset Bluetooth zone is clickable;
taps elsewhere are no-ops (no conflict with splash toggle)
Docs:
- README: drop Controller from screens table, rewrite Physical buttons
table, remove Gesture controls section
- CLAUDE.md: update file map, button assignments, drop gesture refs
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).

Move all communication from USB to BLE. The device now advertises as
"Claude Controller" and acts as both a BLE HID keyboard (for touch
gestures) and a GATT data server (for usage updates from the daemon).
- Add NimBLE-Arduino BLE module with custom GATT service + HID keyboard
- Add third screen (Bluetooth) with connection status, MAC, reset button
- Rewrite daemon in bash using bluetoothctl/busctl for BLE GATT writes
- Add screenshot capture via LVGL snapshot over serial
- Remove TinyUSB mode — normal pio upload works again
- Update README with BLE architecture, screenshots, gesture docs

Two screens switchable by tapping the Claude logo:
- Usage screen: session and weekly utilization with animation
- Controller screen: touch gesture HID keyboard controls
Controller screen features:
- Lucide icons for ESC, DEL, left/right arrow buttons
- Gestures panel with hand icon header and hint list
- Session usage bar with reset timer at bottom
- Hold anywhere for voice dictation (space key)
- Hidden Ctrl+Space on logo hold
Also fixes stuck modifier keys with releaseAll() after each keystroke.

Physical desk monitor that displays Claude Code usage limits (5-hour session
and 7-day weekly utilization) on an ESP32-S3 touchscreen via USB serial.
Firmware: LVGL 9 dashboard with LovyanGFX on SC01 Plus, Anthropic brand
colors and custom fonts (Tiempos, Styrene B, DejaVu Sans Mono), Claude
spinner animation with rotating status words.
Daemon: Pure bash script that reads the Claude Code OAuth token, makes a
minimal Haiku API call, extracts usage from rate-limit response headers,
and sends JSON to the ESP32 over serial. Uses inotifywait for instant
USB plug/unplug detection.
