Touch: the generic esp32p4 Arduino variant defines BOARD_SDMMC_POWER_PIN 45 (the Function EV board's SD power switch). SD_MMC.begin() did pinMode(45, OUTPUT) and SD_MMC.end() cleared it, so the peripheral manager detached I2C0 (i2cDeinit) that ESP32Board::begin had started on SDA45/SCL46. Every Wire call after the boot SD probe failed with "bus is not initialized". build.sh now guards that block behind WADA_SDMMC_NO_POWER_PIN (defined for this board, whose card has no power switch), failing the build if upstream drifts. GT911 init now goes: LDO4 check -> bus begin/re-begin with a logged result and the pin owner on failure -> RST/INT strap per the datasheet (0x5D, then 0x14, then RST only) -> full scan logged -> address pick -> product id, firmware, config version, resolution and touch count logged. Three attempts, 700 ms apart, each actually on the bus. Tiles: no free flash for a "tiles" partition without moving user data, so CAP_TILES_ON_STORAGE routes the cache to microSD or the internal 'storage' LittleFS, now with a 30% (min 2 MB) free-space floor for user data. The "tiles" mount is only tried when the partition exists (no more partition not found / format failed errors), and logs name the board. SD: one quiet 400 kHz identification probe at boot; an empty slot logs "no card or not responding" once and skips the 3-step ladder. C6: the INIT-event firmware version is kept (build.sh patch) and logged plainly against the host version; an older C6 gets 60 s Wi-Fi retries. Also: no setCpuFrequencyMhz on the P4 (fixed 360 MHz), no SPIFFS purge walk where SPIFFS is not mounted, and SdNvsPrefs asks nvs_open() before a read-only Preferences open so absent namespaces no longer log NOT_FOUND.

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 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. Region discovery, known-region management, and per-channel flood scopes are described in 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:
- 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 prohibits offline downloads from that community service. - 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.
- Open Processing Toolbox → Raster tools → Generate XYZ tiles (Directory).
- 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.
- 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:
- Connect the device and the browser to the same Wi-Fi network.
- Open Transfer from the device's app drawer, visit the displayed URL, and enter the six-digit session code.
- 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.
- Existing tiles are skipped by default, allowing an interrupted upload to be resumed. Enable Replace existing map tiles when intentionally refreshing a pack.
- 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 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
pio run -e crowpanel_35_companion_radio_touch # CrowPanel Advance 3.5
pio run -e crowpanel_50_companion_radio_touch # CrowPanel Advance 5.0
# 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.
