New SCREEN_PROVIDER (Menu → "Provider"): shows the active provider's brand name
in the accent colour (recolors live on a theme switch via the shared accent
style) and its "i / c" position among the enabled providers. A Switch button
notifies {"cmd":"provnext"}; the daemon owns the enabled set/order and cycles to
the next one, so the watch stays dumb. When only one provider is enabled the
button is replaced by a hint.
main.cpp parses the optional pnm/pi/pc payload fields into ui_set_provider_badge.
Builds green on all four boards (206/216/18/216_c6); verified on 2.06 hardware
(OpenAI green theme + "2 / 3" + Switch).

The watch recolors to the active provider's brand, live, and it's cheap to add
more providers later.
Firmware:
- theme.h: expose THEME_ACCENT_HEX; ui.cpp: COL_ACCENT becomes a runtime
lv_color_t backed by a shared style (s_accent_style). Static accent widgets
(launcher tile icons, usage status line, session tokens) attach the shared
style, so ui_set_theme() recolors them instantly via lv_obj_report_style_change
— no widget tracking, no recreation.
- ui_set_theme(pv, accent_rgb): swaps the accent + a small logo table keyed by
provider id (fallback to the Claude mark until a provider ships a logo). Change-
guarded, so the ~3s payload cadence doesn't churn.
- main.cpp: parse "pv" (id) + "ac" (0xRRGGBB) from the payload and apply.
- Adding a provider needs zero firmware color edits (accent is data-driven) and
at most one logo-table row.
Daemon: push "ac" = active provider's brand accent alongside "pv".
Test fix: test_providers used asyncio.run(), which closed the suite's shared
event loop and broke every later get_event_loop() test (Py3.13) — mirror the
repo's _run() helper instead.
Verified on the 2.06: forcing an OpenAI-green theme recolored the live launcher
icons (report_style_change path). 216 builds clean; daemon suite 94 passed.
Watch-side features developed on the AMOLED-2.06 and shared across all boards:
- BLE command channel (…0005, notify watch→PC) via ble_send_command(); the
watch stays "dumb" and the daemon maps commands to Home Assistant.
- Battery detail screen + protective low-voltage cutoff; power HAL gains
battery_mv() / shutdown(), with battery_est.{h,cpp} for the time-left anchor.
- Home screen: dynamic 2-column button grid driven by the desktop config
(RX "btns" labels); tap notifies {"cmd":"btn","i":N}.
- Dimmer screen: IMU tilt-joystick over the light's brightness / color temp.
imu_hal_read_accel() added to the HAL (real on 2.06/2.16, no-op elsewhere);
streams absolute {"cmd":"bri"|"ct","v":..}; daemon seeds the dial via "dim".
Per-board tilt axis is calibrated with the DIM_CALIB overlay (off by default).
Multi-board fix: enable LV_FONT_MONTSERRAT_20/28 on the 2.16, 1.8 and C6 envs.
Shared ui.cpp uses these glyphs for the launcher tiles and back chevron, so
those three boards had failed to compile since the Phase-2 UI landed. All four
envs now build clean. README: correct the Windows pairing name to "Clawdmeter".

Decouple the two data sources that share the BLE link:
- Anthropic usage / rate-limit: still polled every 60s.
- Windows media session: read every 3s and pushed the moment the track or
play/pause state changes, so a song change reaches the watch in seconds
instead of at the next 60s poll. The last usage payload is cached and merged
into each now-playing write, so the firmware always gets one complete JSON
object and the usage screens never blank between polls.
Fix: long media titles (a 44-char Cyrillic title -> ~256 B once json escapes
each char to \uXXXX) overflowed the ATT MTU, so every write-without-response
failed with E_INVALIDARG and tripped the zombie-link break in a reconnect loop.
Switch the RX write to response=True (WinRT does a reliable long write; the RX
char already advertises WRITE and NimBLE reassembles into its 512 B buffer) and
serialize with ensure_ascii=False so Cyrillic goes as 2-byte UTF-8 instead of
6-byte escapes. Verified on hardware: stable link, writes succeed across the
60s heartbeat.
Firmware: only re-set the Now Playing labels when the track / state actually
changed, so the faster cadence does not restart the circular title-scroll
animation on every (often identical) payload.
requirements-windows.txt: add winrt-Windows.Media[.Control]. Phase 5 imports
them but they were never declared, so now-playing silently degraded to
"nothing playing" on a fresh machine.
tests: fix two stale poll_api assertions that expected an "ok" key poll_api has
not emitted since that flag moved to the caller (connect_and_run).

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.

The Session screen's tokens/cost are computed locally from transcripts and need
no network, but they were gated behind a successful rate-limit API call — so an
expired OAuth token or API outage froze the whole watch.
Daemon: always compute and send local usage every cycle; rate-limit utilization
is now best-effort and merged on top when available, with ok=true only when it's
fresh (ok=false on expired token / API down). poll_api returns just the
rate-limit fields; connect_and_run owns the payload + ok flag.
Firmware: ui_update always refreshes the Session screen; the rate-limit bars and
the freshness clock update only when data->ok, so the usage view falls back to
its existing idle "Zzz" state instead of showing stale or zeroed percentages.
Verified: with the token expired (HTTP 401) the daemon still sends
tk/tc/tn/to + ok:false and the Session screen keeps updating.

The total is ~97% cache reads, which reads as implausibly large on its own.
Show the cache-inclusive total as the headline token number and the output
tokens ("what Claude actually generated", ~1.1M) as a small line beneath it —
impressive total, believable sub-number. Daemon sends a new `to` field; firmware
parses output_today and renders it. Re-spaced the Session layout for the 5th row.

The count is assistant API turns (each tool-use round is one), not user chat
messages — "messages" misled into reading it as conversation count / all-time.
"requests" reads correctly.

Daemon: compute_today_usage() sums today's Claude Code token usage across the
local project transcripts (~/.claude/projects/**/*.jsonl), reading only files
modified today so the scan stays cheap, and prices it with Anthropic list rates
to show the equivalent API cost (the ccusage-style flex for subscription users).
The compact fields tk (total tokens), tc (cost in cents) and tn (message count)
piggyback onto the existing 60s BLE payload.
Firmware: UsageData gains tokens_today (64-bit) / cost_cents_today /
messages_today; parse_json reads tk/tc/tn; a new Session screen shows the cost
as the hero with total tokens and message count below, refreshed from ui_update
so it's current whenever opened. Wire SCREEN_SESSION to the real screen (was a
stub). Verified end to end: daemon sends e.g. tk=105374109 tc=26838 tn=663.

Add a Soundpad app screen: a 2x3 grid of colored pads that each emit one of
F13..F18 over the existing BLE HID keyboard, for mapping to a host soundboard.
Key release is deferred via a one-shot LVGL timer so the UI thread never blocks.
Raise the HID report-map keycode ceiling from 101 (0x65) to 115 (0x73) in
ble.cpp so F13..F24 (0x68..0x73) are within the declared key-array range — they
were silently undeliverable before. Wire SCREEN_SOUNDPAD to the real screen
(was a stub).
NOTE: the HID report descriptor changed, so the host must re-pair to refresh its
cached map before F13..F18 are recognized.

The tile grid used track_cross_place=CENTER, which vertically centers the
overflowing block of rows — hiding the top row under the title and springing
back to it after an elastic pull. Switch to START so rows stack from the top:
the first row sits under the title and the rest is reached by scrolling down.
Nudge the back chevron down/right so it clears the rounded top-left corner.

Replace the splash<->usage tap-toggle with a home + launcher model. Tapping the
Claude logo on the home (usage) screen opens a scrollable 2-column launcher
driven by an app registry — adding a screen is one registry line plus a builder,
no edits to shared navigation. A shared back chevron returns launcher->home and
app->launcher; tapping the splash returns to home.
Screens wired: Usage (home) and Animations (splash) are real; Bluetooth shows
live connection state + device name + MAC; Soundpad/Session/Now Playing/Home
point at a shared "coming soon" stub until their phases land. Enable Montserrat
20/28 for the LVGL symbol glyphs used by tile icons and the back chevron (the
brand Styrene/Tiempos fonts are Latin-only). Flash 20.3% -> 20.9%.

When the host is connected over BLE but no usage update has landed recently
(~90s — token expired, daemon down, host asleep), show a calm idle screen
instead of leaving hours-old numbers on screen as if they were live: a shrunk,
animated "expression sleep" creature (reused claudepix art) centered between
the header and the status line.
The usage view resolves to three sub-screens via a data-freshness timer: live
panels, this idle screen, or the existing pairing hint. The bottom status line
animates present-participle gerunds: the idle screen alternates "Listening…" /
"No data…" (alive + explicit), the disconnected screen uses "Waiting…"
(replacing the static "Disconnected…").
splash_mini_create()/splash_mini_tick() render any claudepix animation shrunk
into an arbitrary parent, keeping the art data in the splash module.

Removes the Bluetooth screen — the device now has just splash + Usage. Keeps
main's responsive Layout intact.
- ui: drop the Bluetooth screen, ui_cycle_screen, and SCREEN_BLUETOOTH. The
bottom spinner becomes a status line — Connected / Disconnected / Pairing…
(via ble_has_bonds()) plus the whimsical messages when connected and idle.
A "To pair / hold the power button / for 3 seconds, then release" hint shows
while disconnected so the screen isn't empty.
- main: hold-to-pair gesture (pair_tick) — hold PWR ~3s then RELEASE clears
bonds and re-advertises. Clearing on release (not while held) means holding
to power off (8s hardware shutdown) leaves the bond intact; disarms at 6s.
PWR short-press now cycles brightness on the Usage view (animations on splash).
- ble: add ble_has_bonds() for the status line.

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.

Port the firmware to a second Waveshare AMOLED board variant alongside
the original 2.16" / 480×480. Selection is at build time via a board
macro; both envs continue to build and flash independently.
Hardware delta vs AMOLED-2.16:
* Display: SH8601 QSPI (vs CO5300), 368×448 portrait (vs 480² square),
SCLK on GPIO 11 (vs 38), RST routed through an XCA9554 I/O expander
(vs direct GPIO).
* Touch: FT3168 @ 0x38 (vs CST9220 @ 0x5A). Driven by a ~30-line
inline FocalTech-protocol reader in main.cpp — Waveshare's
Arduino_DriveBus library is GPLv3 and would force the project's
license, which the README explicitly avoids.
* I/O expander: new XCA9554/PCA9554 @ I2C 0x20 gates LCD_RST, TP_RST,
audio amp enable, and the PWR button. Wrapped in io_expander.{h,cpp}.
Must initialize BEFORE display/touch or both stay in reset.
* PMU + IMU: same AXP2101 + QMI8658 as 2.16, so power.cpp/imu.cpp
largely reuse. IMU is initialized for I2C bus health but rotation
is fixed at 0° (the portrait panel doesn't benefit from auto-rotate
and the strip-rotation CPU path is excluded entirely).
* Buttons: only BOOT (GPIO 0) is a direct GPIO; PWR is read via
XCA9554 EXIO4 polling. No third button — the AMOLED-2.16's
Shift+Tab key (GPIO 18) is dropped for this board.
* Flash: 16MB (vs 8MB), partition table set to default_16MB.csv.
Code structure:
* display_cfg.h hosts a #ifdef BOARD_AMOLED_18 / #else / #endif split
with a PlatformDisplay typedef so call sites elsewhere stay clean.
* main.cpp, power.cpp, ui.cpp, splash.cpp gate board-specific bits on
the same macro. Layout constants (panel heights, content Y, font
choices on the Bluetooth screen) compress for the 368×448 portrait
footprint so two usage panels + bottom animation label fit without
horizontal overflow.
* Splash scales the 20×20 pixel-art grid to 360×360 (CELL=18 vs 24)
and centers in the portrait canvas.
* Old AMOLED-2.16 env is unchanged at the source level (gated under
#ifndef BOARD_AMOLED_18) and continues to compile + flash on the
original hardware.
CLAUDE.md updated with the two-board pin maps, build/flash commands
for both envs (macOS + Linux device paths), and the per-board gotchas.

The two panels in init_usage_screen() differed only in y-offset, pill
text, and which globals received the children — same widget tree, same
sizes, same positions. Fold into make_usage_panel() so the layout intent
shows up in two call sites instead of being duplicated by hand.
Verified by pixel-diff: pre- and post-refactor screenshots of the Usage
screen are byte-identical.
- 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
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
Each gesture hint now wraps its gesture in white (COL_TEXT) and the
action in dim gray (COL_DIM), stacked vertically. Replaces the prior
single-line "Gesture: action" format that wrapped at arbitrary points.
- Drop "of current session" trailing text from the percentage label so
it no longer overlaps the right-aligned reset countdown
- Shrink hint font from styrene_24 to styrene_20 and enable WRAP mode
with center alignment so each hint fits the narrow center zone
- Shift all three titles by +16 from screen mid so they center between
the logo (right edge ~100) and battery icon (left edge ~412)
- Bluetooth screen: increase Reset zone height 70 -> 110 for breathing
room around the trash icon + label
- Bluetooth screen: drop the "Bluetooth Low Energy" footer
- 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
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).

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.
