The repo has apparently only ever been built on case-insensitive
filesystems (macOS/Windows): every #include in the codebase uses
intended PascalCase/CamelCase header names (e.g. "SettingsScreen.h",
"WiFiMQTT.h"), but 28 of the actual files on disk were saved with
inconsistent casing (e.g. "Settingsscreen.h", "wifimqtt.h"). On a
case-sensitive filesystem (Linux) this is a hard compile failure, not
a cosmetic mismatch -- confirmed by running `pio run -e meck_audio_ble`
on Gentoo Linux, which failed immediately on "target.h: No such file
or directory" and a cascade of similar errors as each fix exposed the
next one.
Root causes, two flavors of the same underlying bug:
1. Header filename casing (29 files renamed via `git mv` to preserve
history): examples/companion_radio/ui-new/*, examples/simple_repeater/*,
and two variant-local headers (PCF85063Clock.h, TCA8418Keyboard.h x2).
Verified safe before renaming: every file has exactly one consistent
intended casing across all the places that #include it (checked via
a repo-wide scan comparing every #include against on-disk filenames,
zero conflicts found), so each rename is a pure no-op for behavior.
2. PlatformIO config paths using the wrong case for variant directories
that are actually lowercase on disk (variants/lilygo_tdeck_pro,
variants/lilygo_t5s3_epaper_pro):
- `-I variants/LilyGo_TDeck_Pro` / `-I variants/LilyGo_T5S3_EPaper_Pro`
in build_flags (3 occurrences, including lilygo_tdeck_max's
reference to TDeck Pro's shared headers) -- broke header resolution
for target.h and friends.
- `+<../variants/LilyGo_TDeck_Pro>` / `+<../variants/LilyGo_T5S3_EPaper_Pro>`
in build_src_filter (2 occurrences) -- silently excluded the board-init
.cpp files (TDeckBoard.cpp etc.) from compilation entirely, which
didn't fail until the *link* stage ("undefined reference to
radio_init()", `TDeckBoard::begin()`, etc.) since PlatformIO's glob
just matched nothing rather than erroring.
Verified fix: `pio run -e meck_audio_ble` now compiles, links, and
produces a firmware image cleanly (RAM 53.1%, Flash 49.6%).

Keyboard LED brightness (T-Deck Pro MAX):
Adds a "Keyboard LED" row to Settings (MAX only), below Backlight
Brightness and mirroring it: 5-100% in 5% steps, default 50%. The
both-shifts keyboard backlight toggle previously used a hardcoded PWM
level of 8 (~3%), too dim for some users; it now reads the stored
percentage and maps it to PWM, taking effect on the next toggle.
- NodePrefs.h: new kb_backlight_pct field (5..100, default 50)
- Settingsscreen.h: ROW_KB_BACKLIGHT row plus label/edit handling
- DataStore.cpp: load/save/clamp, appended so existing prefs files stay
compatible (fall back to 50%)
- main.cpp: toggle uses kb_backlight_pct (percent -> PWM) instead of 8
Standalone unread counter fix:
On standalone builds the home-page MSG count and channel-picker unread
badges never updated, although messages arrived and displayed normally.
ArduinoSerialInterface::isConnected() is hardcoded to return true (a plain
UART has no connection state), so the periodic
setHasConnection(_serial->isConnected()) in MyMesh left hasConnection()
permanently true -- making UITask mark every received message read on
arrival. The same stuck flag also suppressed the DM counter and the
new-message screen wake. Guard the call so only builds with a real
companion (BLE / WiFi / wired SERIAL_RX) derive connection state from the
interface; companion-less builds report not-connected. The core
ArduinoSerialInterface is unchanged, preserving wired-companion behaviour.
- MyMesh.cpp: guard setHasConnection() for companion-less builds
The fix (six sites: 948, 978, 1519, 1651, 1719, 1906): the indexer now chooses pixel-vs-char wrapping from _display->getFontStyle(), the same basis the renderer (1200), the layout sizing (1336), and the cache key already use. With all four agreeing, the indexer's recorded page boundary lands on the exact byte where the renderer's height-based stop lands — no more swallowed run between pages.
Version bump (INDEX_VERSION 13 → 14): your existing .idx caches were built by the old indexer and would otherwise be reloaded as-is (same font key), so the fix would appear to do nothing. Bumping the version makes the loader discard every v13 cache and rebuild it.
All six edits are in and braces balance (267/267). Here's what changed in Audiobookplayerscreen.h:
PNGdec include (47) and cover size 40→30 (67) — 30 virtual units ≈ 55px.
PNG draw callback coverDrawCallbackPNG (147) — nearest-neighbour downscales the 256px source line-by-line and dithers to 1-bit using the same Bayer matrix as the JPEG path. The decoder is heap-allocated per-decode (new PNG()), mirroring how the JPEG path uses new JPEGDEC(), so there's no permanent BSS cost.
decodeFolderCoverPNG() (419) + tryLoadFolderCover() (505) — reads cover.png from _currentPath into PSRAM and decodes it.
Hooks in both openBook (1099) and advanceTrack (1198), so the cover loads on open and persists as tracks auto-advance within an album. It only loads when there's no embedded cover, so M4B/ID3 embedded art still wins; music (no embedded art) gets the folder PNG.
Layout (1531, 1556) — cover now draws below the artist line, above the status/Paused-Vol line, exactly where you wanted it.
