- Battery curve: NodePrefs batt_curve_mv[11] (voltage at 0..100 %, all
zeros = built-in LiPo curve, sentinel 0xC0DE0032). ui-core/Battery.h
uses it for every percentage. L1: Settings > System > Batt curve list
(Left/Right 10 mV, Reset); L2: Settings > Power > Battery curve chart
with draggable points and a line at the cell's voltage.
- L2: the Nodes map is the full navigation map plus the nodes, Back
returns to Nodes; the favourite button is lit while it is one; pinning
to the Home dial uses a thumbtack (fonts regenerated); minimap dots
follow the accent; arranging tiles shows where they land while dragging;
emoji row in Diagnostics > Font.

Recording / live share and the download stack in a column at the top
centre, empty when nothing runs; the recording pill is plain text with
only its mark coloured (red stop, accent pause / live) -- all-red text
was hard to read over the map. The credit, scale bar and zoom share one
pill bottom left (a tap shows the credit). Every map pill is 22 px with
round ends.

A 404/503 answer (OpenTopoMap renders on demand) went to an immediate
2 s retry and counted as network loss, so each tile then waited up to
60 s. Answered errors now go straight to the retry list; long pauses
only when there is no answer at all. Three retry rounds (20/60/120 s)
for the tiles still missing, transfers cut after 30 s, failures logged
on serial.
Download popup tidied: title + floating close, percentage instead of
tile counts (also on the map pill), no dead zoom row, no finish toast
after Stop or while the popup shows the result.

A group row's text column (and an info row's key) grows into what the
controls on its right leave, and LVGL lays out children before their
parent, so its labels were first measured 1 px wide; LVGL also works out a
new label's height at its old width (0) before the real one. Each height
that changed then took another pass up the screen: 4-6 passes per screen.
rowsFit(), run before a frame's layout (LV_EVENT_REFR_START) and by
layoutNow() in place of every explicit lv_obj_update_layout(), gives each
new row's growing child the width the flex will give it, worked out from
the other children's styles and text, and labelFit() measures wrapping
labels at their real width up front. The grow stays, so a control that
can't be sized ahead only falls back to the old passes.
Layout on the device: Display page 34 -> 24 ms, Bot 33 -> 18, Quick
37 -> 22, Radio 26 -> 18, Diagnostics 20 -> 12. Sim screenshots of 26
screens unchanged.

Found by counting flushes on idle screens in the sim:
- The compose field's cursor blinked (a redraw every 400 ms) as soon as
a conversation opened, the keyboard hidden: lv_keyboard_set_textarea()
focuses the field, and LVGL only stops a blink when the cursor moves.
fieldFocus() sets the state and nudges the blink; also used for the
WiFi and channel fields, which left theirs running.
- lv_obj_align_to() restyles on every call, so the status bar's icons
redrew every second; placeLeftOf() moves them only when they move.
- Text colours set every second (nav bar, GPS status, Diag errors) go
through setTextColor(), which skips an unchanged colour.
- A LV_LABEL_LONG_DOT label writes its "..." into its own text, so
setText() never matched and rewrote it every refresh (the nav bar's
hint); labelShows() reads past the dots.
- The map area, the area-outline, trail and vector-label layers were
invalidated on every map refresh (every 3 s, a full-map redraw); now
only when the view or what they draw changed.
Idle map: 17 -> 1 flush in 5 s; list and settings screens: 0.

- The map screen's own fill is only painted where the map area doesn't
cover it (the strip it uncovers as it drifts in); the area and the
opaque status bar hide the rest. ~2 ms a frame.
- With every visible cell holding a tile, the map area drops its fill and
grid, which lie under the tiles anyway, and still reports that it
covers what's below (coversOwnArea, shared with the frozen popup
image). The Home minimap drops them the same way. ~5 ms a frame.
Full map frame ~50 -> 46-48 ms on the L2.

Kept for the optimisation pass before a release:
- perfDrawProfile(): a full redraw timed per object (its own drawing),
totals by kind and the costliest listed -- on settings pages, Contacts,
Home, the map and under a frozen popup; the screen's entrance frames too.
- Per screen: build, layout, first draw and redraw apart.
- A popup over Home: a full frame dimmed live and frozen.
- The reset reason and a core dump summary at start.
- -D PERF_WRAP_TEXT with -Wl,--wrap= of lv_text_get_size_attributes,
lv_layout_apply, lv_obj_get_style_prop_internal and lv_obj_send_event:
text measured, flex runs, style reads and events per screen.
- -D PERF_KEEP_USB leaves the USB popup up.

Measured on the L2 (steady full frames): Settings page 37.7 -> 31.4 ms,
Display 41.5 -> 37.9, Contacts 34.6 -> 32.9, Home 37.3 -> 32.4.
- styleSurface() leaves boxes in the page colour unpainted; styleOpaque()
for the screen and the status bar, which things slide under.
- group() cards clip their corners only while a row is held
(rowPressable(), shared by the tappable rows).
- rowSlider(): the track an opaque tint (theme::mix(), also behind
ACCENT_DIM) instead of 20 % accent blended every frame.
- Map buttons, pills, scale, nav bar and the Home minimap labels opaque.
- Screens drift in without the fading cover: its full-screen blend was in
every entrance frame (page 39 -> 29 ms).

PNGdec (bitbank2, 1.1.6) decodes a tile a row at a time straight into
RGB565, without lodepng's 256 KB RGBA buffer; the trail overlay goes through
it too, blended by hand for palette-with-alpha and RGBA. It lives in its own
file (ui-lvgl/TilePng.cpp) because its zlib headers put DONE/EXTRA in the
global namespace. lodepng stays the fallback and the sim's decoder.
Same 20 tiles: decode 78 -> 50 ms, trails 42 -> 17.5 ms, a whole tile
170 -> 105 ms; the map with trails is pixel-identical.

- TileCache: request() hands z/x/y to a task on core 0, which renders into
a spare buffer; poll() swaps it into the LRU slot (stale results dropped
after drop()/invalidate()); the sim runs the job at once
- MapScreen / Home map place finished tiles as they arrive; the longest
UI stall with the map opening goes from ~340 to ~170 ms
- LVGL allocates from the PSRAM heap (lv_mem_psram.h), safe from both
tasks; LVGL's own pool is gone
- lv_conf: notes why LV_OS_FREERTOS with two draw units stays off
(measured slower: drawing is bound by PSRAM bandwidth)
- UI_PERF_TEST: the map (tile read/decode, pan, redraw), build time and
the longest loop pass per screen

Trail on the L2: 32768 points every 5 m, no simplification, no point
spacing setting; copied to the card every minute and restored at power-on.
The line keeps up with the position dot (incremental sync, pending point).
Map: a tap's finger jitter no longer turns follow off; the GPS button
shows when the map follows. The trail is drawn as one polyline with
breaks and off-view chunks skipped (an lv_line queued a draw task per
point).
Fewer rebuilds: conversation bubbles patched (new messages, delivery
marks), home mini-map dots reused, Nearby rows rewritten in place,
history read in runs and each file opened once.

- CPU at 80 MHz with the screen on after 2 s without touch or animation;
a touch restores the full clock before its frame is drawn
- setText(): periodic refreshes no longer redraw unchanged labels
(status bar, Home, lock, Diag, GPS, compass, clock, map, nav, nearby)
- map markers kept across the 3 s rebuild when unchanged
- app connected: the loop blocks until a BLE frame arrives
(serialFrameArrived / hasPendingFrames) instead of polling every 2 ms
- PSRAM: boot frame sprite and the HTTP response buffer released
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Dead code gone: anim::fadeHide, radioctl::presetCount, the L2 board's
setSdPower / setGrovePower / expanderOK (awRead, gnssReset now private).
- buttonBar() / barButton() replace 7 copies of the popup button row.
- confirmBody(): one red-button confirm for reboot / power off, reset
counters, admin commands, preset and scope delete.
- tapConfirmed(): the 11 "tap again" buttons share one mechanism, 3 s
everywhere, the label restored when left alone.
- noteLabel() for ~30 wrapped notes.
- localTm() in NodePrefs.h and one MONTHS table: lvgl, MsgExpand, the L1
clock and lock screen.
- The sim keeps UI settings in an in-memory nvs::, so one set of load /
save helpers serves both.
- Asleep, the loop wakes every 50 ms (the button / touch poll), not 20.

- USB through TinyUSB (ARDUINO_USB_MODE=0) instead of USB-Serial/JTAG: the
serial port stays, and plugged into a computer (enumerated, the bus not
suspended -- on battery an unplug only shows as a suspend) the device asks
"Charge only / USB drive". As a drive the firmware lets go of the card and
the computer gets its sectors; ejected or unplugged, the device restarts.
- Incoming messages: a banner slides down from under the status bar (icon,
sender or channel, two lines of the text from history); a tap opens the
conversation (not while locked), a swipe up dismisses it, not shown for
the conversation already open. Toasts moved up there too, under the banner
when both are up; the ones only echoing a switch or a choice are gone.
- Storage > Format card: a popup saying what goes, then Format tapped twice;
one FAT32 volume over the whole card (readable or not), then a restart.
- A deliberate restart shows a full "Restarting..." screen with the reason
instead of the screen just freezing.
- The screenshot flash is a thin frame round the edges: a full-screen fade
redrew all 320x240 each step and tore.

LVGL 9.2.2 measures a SIZE_CONTENT box from its children as scrolled, so an
elastic pull past the end of a capped popup list shrank it by the overshoot,
again on every pull. lvgl_patches.py fixes calc_content_height in the
downloaded library (a build middleware for PlatformIO, called directly by the
sim's build_wasm.sh).
The five popups that each built the same panel now share popupOpen() (fit to
content / full height / under the status bar).

One .vpk file per region in /vmap (header, sorted index of tiles and
points, then the data), read in place with the index in PSRAM; loose
{dz}/{x}/{y}.vt/.vp files still work. osm_vector.py writes packs
(--pack/--name), reads OSM PBF extracts for a box (--pbf/--bbox, via
pyosmium) and picks label languages (--lang). Map tools > Vector regions
lists the packs on the card: show one on the map, delete it. No
on-device download: packs are made with the tool.

Hiking routes are stored per stretch with the waymark colours of every
route along it and drawn as side-by-side stripes on a white band (half
the route ways in the Tatra sample carry two or more routes), less
simplified; demanding / alpine paths are dotted. Named points (places,
peaks with height, huts, passes, springs, viewpoints, caves) come in
small .vp files and are placed by priority as a layer over the tiles,
clear of each other and of the map controls.

tools/maps/osm_vector.py turns Overpass JSON into VT2 tiles (data zooms
10/12/14, per-feature bbox, simplified); VectorTileProvider draws them
into 256 px tiles (scanline polygons, thick lines with round joins) with
a small PSRAM cache of data files. Behind Map tools > Vector map (test),
raster where there is no vector data.

- Download an area: a frame with four corner handles on the map (kept in
world coordinates, the map pans / zooms under it); a bar gives its size,
zoom range, tile count and size, the trails switch and Get; areas on the

/sdcard/maps/areas.txt) -- show (framed, outlined), rename, fill gaps,

tiles another area covers)
- TileDownloader: force and per-job trails options

A square grid drawn under the tiles (map, Nodes map, Home minimap), its step
a round distance for the zoom in metric or imperial units, with a scale bar
one step long; gives position and scale where no tile is loaded. The
missing-tiles hint moves up, off own position.

Waymarked Trails' transparent hiking layer, kept in /sdcard/maps-trails and
blended over the base tile at render time (Map tools > Hiking trails, NVS).
An area download fetches each tile's trails after its base tile, so
re-running an area on the card adds just the trails; with live tiles on, a
shown tile missing its trails has them fetched. Tiles without a trail are
stored as 0-byte files (no cluster on FAT).

Info cards drop the default 8 px row gap so text sits centred between
hairlines. The alarm Repeat list is compacted to fit above the dropdown.
creditText() keeps "(c) Name" and licence names like CC-BY-SA together
in About and the map credits toast.

Power: the UI loop sleeps until something is due (never with packets
queued); screen off puts the CPU at 80 MHz, the GT911 to sleep (unless a
tap wakes the screen) and the LP5814 in standby. GPS off now cuts the
L76K's rail and UART on the L2 (L2GpsProvider). The battery divider is
powered only for a reading (measured: settles at once); readings within
2 s are reused. The SD mount is retried at most every 5 s.
Fixes: WiFi left on after leaving a scan, live tiles' WiFi kept with the
screen off on the map, an ADC read every second for the status bar, touch
polled on every pass while dark, a scan cutting an update's WiFi, relay
count not refreshing in a channel thread, raw @[nick] in room previews.
Labels skip unchanged text (no redraw).
Helpers: scrollList, dimOverlay, settingRow, flexBox, nvs::get/put,
trailFilePath (a second save in the same minute no longer overwrites),
unreadTotal. Dead code removed.

Mentions: "@[nick]" in message text becomes "@nick" in the accent colour
(a span group); a mention of us is underlined and its bubble outlined.
Chat previews and the message popup's quote show "@nick" as well.
Emoji: every single-codepoint Twemoji and every flag, 16 px RGB565A8 in
flash, as the fallback font of each text size (fonts/ui_emoji.c, data
generated by fonts/emoji.py). Joiners, selectors and skin tones take no
space; a regional-indicator pair is swapped for the flag's private
codepoint before text reaches a label. Twemoji credit in Settings > About.

A progress bar and one line of counts while downloading (the zoom row
hides, it can't change then), failures on one line, the source as

Tiles fetched while browsing online go to /sdcard/maps-live with an
index of arrival order; past the limit (Settings > Storage, 16 MB-1 GB,
default 64 MB) the oldest are deleted a few per loop. Storage shows

touched. Roadmap: live tiles done, second batch of user items added.

- Tile fetch and OTA tasks run at idle priority: HTTPClient's read loop
only yields with delay(0), which at priority 1 starved IDLE0 until the
task watchdog reset the device (decoded from the core dump)
- A failed tile is retried once; failures in a row pause 5 s ... 60 s on
the same tile, and the download gives up only after ~5 min of nothing
- The source's last zoom level (OpenTopoMap 17, else 19, or line 3 of
source.txt) caps the download range and live tiles; past it the map
magnifies the parent tile
- OpenTopoMap's "no tile" picture is never saved, and copies saved by
earlier builds are dropped when read
- The placeholder check only runs on a fresh area and for pictures with
content: plain sea / empty land tiles are genuinely identical

- Anim.h: screens emerge from the middle (background cover fades, content
drifts 6 px), Home pages slide, popups and toasts rise and fade in
- Theme.h: accent rules (fill = primary action, dim fill = selected, text =
names/counts/modes), theme layer over the default theme, radius tokens,
accent colour picker (Settings > Display & power > LOOK, NVS mc_ui)
- Splash with the Solo and upstream versions
- Status icons in equal cells, L1-style relay marks, path window with a hop
diagram, tile download popup fits the screen (WiFi only in Settings)
- Perf: uncompressed fonts, two 120-line PSRAM buffers (~48 -> ~33 ms per
transition frame); UI_PERF_TEST harness

- Screen PIN (Settings > Display & power > Security): 4-8 digits in NVS,
keypad on the lock card after every wake and on boot, 5 misses -> 30 s pause
- Live map tiles: missing tiles at the current zoom are fetched over the saved
WiFi, written to the card and drawn; WiFi drops 30 s after leaving the map;
"Live tiles" switch in Map tools
- Firmware update (Settings > System): checks the fork's latest release,
streams the -ota.bin into the spare app slot over TLS verified with the
Arduino 3.x CA bundle, checks image magic/chip id, restarts
- Release workflow publishes *_solo_lvgl envs (merged image + -ota.bin)

- New env Wio_Tracker_L2_companion_solo_lvgl_v3 on pioarduino 55.03.312-1;

- SerialBLEInterface: NimBLE variant (PIN pairing through encrypted,
authenticated characteristic properties; setAccessPermissions is a no-op)
- buzzer: i2s_std driver on IDF 5 (legacy driver kept for 2.0.17)
- ESPNOWRadio: IDF 5 callback signatures
- ui-lvgl: psramBuf() for trail drawing, tile cache, map marks, list rows,
keyboard maps and message metadata; internal heap back to 2.0.17 level

The map's download button fetches the visible area (overview levels up to
a chosen zoom) into /sdcard/maps from OpenTopoMap or maps/source.txt,
skipping tiles already on the card and rejecting placeholder answers.
Settings > WiFi stores the network in NVS (with scan); WiFi is on only
while a download runs. HTTP runs on a worker task on core 0; the popup
shows link, internal heap and the last TLS/HTTP error.
Internal RAM was the blocker (~13 KB free with WiFi + Bluedroid): the L2
LVGL env now allocates the_mesh in PSRAM (MESH_IN_PSRAM, static RAM
210 -> 87 KB) and mbedTLS allocates from PSRAM. Confirmed on hardware.

Map screen (Home > Map): Web-Mercator tiles from /maps/{z}/{x}/{y}.png on
the card (Meshtastic MUI layout; per-column TPK1 .pak also read), drag to
pan, +/- zoom, re-centre/follow GPS, Nearby nodes with a position as
markers opening node detail. Tiles decode one per loop pass into a
12-slot RGB565 cache in PSRAM. map/TileProvider.h is the swap point for a
later vector renderer: the screen only calls renderTile(). The tile set's
credit line comes from maps/attribution.txt.
L2 mounts the card over SDMMC 1-bit (CLK 2, CMD 3, D0 1). LVGL's lodepng
is enabled; note its LVGL patch returns an lv_draw_buf_t*, not pixels.
LVGL pool 2 MB for PNG decoding. Fonts gain map / users icons.
tools/maps/fetch_tiles.py prepares a card for an area (presets for
Poland), requires an explicit tile URL (tile.openstreetmap.org blocks
offline use) and stops on placeholder images. The LVGL sim preloads
web/maps into the L2's /sdcard and puts its GPS on Kraków.
