jrote1 flashed the June 2025 C3 keyboard firmware, which supports raw column frames, and still got no modifier latching. The probe asked for a raw frame exactly once, on the first poll after boot, and anything other than five bytes with every high bit clear committed the device to legacy mode for the rest of the session. The first I2C read after boot is the least trustworthy one there is: the C3 is still starting, so a short or garbled frame is ordinary rather than exceptional. There was no recovery except a reboot, and a reboot re-rolls the same dice. It now retries for 1.5 seconds before settling for legacy. A single-byte answer is still delivered as a keystroke while probing, so nothing typed in that window is lost, and a genuinely old controller ends up in the same place a little later. The fallback message also says what it actually saw -- how many bytes came back, and whether a column had its high bit set. "Update your keyboard firmware" to someone who just did is not a diagnosis, and this is the same lesson as #274: a failure path that says nothing produces a bug report with nothing in it. Verified on a T-Deck with the newer firmware: still raw mode, latching works. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
A real touchscreen UI for your mesh radio. · open source · GPL-3.0
Touch-UI MeshCore companion-radio firmware for the LilyGo T-Deck / T-Deck Plus, Heltec V4 + TFT and eight other boards (ESP32-S3).
An LVGL touch UI — map, chat, contacts, channels, settings — split out of
meshcomod. The app depends on a
MeshCore fork via PlatformIO lib_deps.

Architecture
This repo holds only the app: the companion_radio glue, the ui-touch
LVGL UI, each board's glue/variants, and platformio.ini. The MeshCore
core is not vendored here — it's pulled as a library via lib_deps from the
ALLFATHER-BV/meshcomod monorepo
(the same repo as the non-touch firmware), pinned by a lean source-only core-*
git tag. The touch-app files this repo owns (TouchPrefsStore, WifiRuntimeStore,
the transports, …) are dropped from the lib via -DMC_VENDORED_TOUCH_APP so they
aren't compiled twice. The build is byte-identical to the original in-tree
meshcomod firmware.
Lua apps use the on-device SDK described in LUA_APPS.md. For WAV/MP3 playback, including a ready-to-sideload transport test app and exact SD and internal-storage paths, see AUDIO_PLAYBACK_TESTING.md.
Build
PlatformIO pulls the core fork and all libraries automatically:
pio run -e heltec_v4_tft_companion_radio_usb_tcp_touch # Heltec V4 TFT
pio run -e LilyGo_TDeck_companion_radio_touch # LilyGo T-Deck
# or just `pio run` to build both
Flash with the NVS-preserving 4-component chain (bootloader / partitions /
boot_app0 / firmware at 0x0 / 0x8000 / 0xe000 / 0x10000) so saved Wi-Fi
credentials survive — not a merged image, which 0xFF-pads and wipes NVS.

License
GPL-3.0-or-later — see LICENSE. wadamesh is copyleft: anyone who distributes a build or a fork must also make their source available under the GPL. This keeps the UI open and concentrates community effort instead of fragmenting it into closed forks.
wadamesh incorporates and depends on MeshCore (MIT, © Scott Powell / rippleradios.com) and other third-party components — see NOTICE for the full list and their licenses. MeshCore-derived files keep their MIT notices; the combined work is distributed under the GPL (MIT is GPL-compatible). The MeshCore fork that wadamesh builds against stays MIT on purpose, so its Wi-Fi/BLE hooks remain upstreamable to MeshCore.
