WADAMESH

A real touchscreen UI for your mesh radio. · open source · GPL-3.0

Touch-UI [MeshCore](https://github.com/meshcore-dev/MeshCore) companion-radio firmware for the **LilyGo T-Deck / T-Deck Plus**, **Heltec V4 + TFT** and other boards (ESP32-S3). An LVGL touch UI (map, chat, contacts, channels, settings) split out of [meshcomod](https://github.com/ALLFATHER-BV/meshcomod). The app depends on a MeshCore fork via PlatformIO `lib_deps`. ## Boards See **[DEVICES.md](DEVICES.md)** for the full support matrix, install paths and per-board status. - LilyGo T-Deck / T-Deck Plus: env `LilyGo_TDeck_companion_radio_touch` (stable) - Heltec V4 + TFT + CHSC6x touch: env `heltec_v4_tft_companion_radio_usb_tcp_touch` (stable) - Tanmatsu (ESP32-P4): built from `tanmatsu/` (ESP-IDF), ships via the Tanmatsu app store; [sideload guide](TANMATSU_SIDELOAD.md) for running your own build - Elecrow ThinkNode M9: env `ThinkNode_M9_companion_radio_touch` (beta); [keyboard & d-pad guide](THINKNODE_M9_SHORTCUTS.md) - RAK WisMesh Tap V2 (RAK3312): env `rak_tap_v2_companion_radio_touch` (beta) - LilyGo T-Lora Pager: envs `tlora_pager_lr1121_companion_radio_touch` / `tlora_pager_sx1262_companion_radio_touch` (beta); [keyboard shortcuts](TLORA_PAGER_SHORTCUTS.md) - Heltec V4-R8 + Expansion Kit V2: env `heltec_v4_r8_tft_companion_radio_usb_tcp_touch` (beta) - LilyGo T-Display P4: built from `tdisplay_p4/` (ESP-IDF); AMOLED + SX1262 by default, with `WADA_P4_LCD=1` for TFT-LCD and `WADA_P4_LR2021=1` for LR2021 (beta) - Attaky Mesh Series: env `attaky_mesh_series_companion_radio_touch` (beta) - Elecrow CrowPanel Advance 3.5: env `crowpanel_35_companion_radio_touch` (beta, hardware validation pending; requires an SX1262 in the expansion slot) ## 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`](https://github.com/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](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](AUDIO_PLAYBACK_TESTING.md). Region discovery, known-region management, and per-channel flood scopes are described in [REGIONS.md](REGIONS.md). ## Offline map tiles Builds with a microSD card expose a **Transfer** app for authenticated browser uploads over the local Wi-Fi network. WadaMesh accepts unpacked 256x256 PNG XYZ tiles in a `z/x/y.png` directory tree. To create a compatible pack with [QGIS](https://qgis.org/): 1. Add a map source whose licence and service terms explicitly permit offline or bulk use. A self-hosted source is also suitable. Do **not** bulk-download from `tile.openstreetmap.org`: the official [OSM tile policy](https://operations.osmfoundation.org/policies/tiles/) prohibits offline downloads from that community service. 2. Frame only the area needed in the QGIS map canvas. Tile counts quadruple at every added zoom level, so a small region and a practical range such as zoom 8 through 16 are preferable to exporting an entire country at zoom 19. 3. Open **Processing Toolbox → Raster tools → Generate XYZ tiles (Directory)**. 4. Use the map-canvas extent, choose minimum and maximum zooms within 3–19, select **PNG**, set tile width and height to **256**, leave **Use inverted tile Y axis (TMS conventions)** disabled, and select an output directory. 5. Confirm the output contains paths such as `12/2048/1362.png`. If obtaining an existing pack instead, extract it first and confirm it has the same XYZ directory layout and that its provider permits offline use and redistribution. To upload the pack: 1. Connect the device and the browser to the same Wi-Fi network. 2. Open **Transfer** from the device's app drawer, visit the displayed URL, and enter the six-digit session code. 3. Choose **Offline OSM map (/tiles)**, select the generated output folder, and start the upload. The browser ignores unrelated files and uploads valid tiles sequentially while preserving their coordinates. 4. Existing tiles are skipped by default, allowing an interrupted upload to be resumed. Enable **Replace existing map tiles** when intentionally refreshing a pack. 5. Close Transfer after completion. In **Map options**, disable **Topographic map** and enable **Tiles from SD card**. Disable Wi-Fi to verify that the uploaded area renders offline. Individual PNG tiles must be no larger than 256 KB. Keep the map provider's required attribution and licence information with any pack you distribute. ## Build [PlatformIO](https://platformio.org/) pulls the core fork and all libraries automatically: ```bash 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 pio run -e crowpanel_35_companion_radio_touch # CrowPanel Advance 3.5 # or just `pio run` to build the configured default environments ``` 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. ## Contributing Contributions are welcome: see [CONTRIBUTING.md](CONTRIBUTING.md). One topic per PR; inbound contributions are accepted under the project's GPL-3.0 license. ## License **GPL-3.0-or-later**: see [LICENSE](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](https://github.com/meshcore-dev/MeshCore) (MIT, © Scott Powell / rippleradios.com) and other third-party components; see [NOTICE](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.
