Add the Seeed SenseCAP Indicator D1L as a new touch target. This step builds and boots to a blank screen; the panel, touch and radio drivers follow in their own commits so each can be reviewed against the hardware it drives. The SX1262's NSS, RESET, BUSY and DIO1, the LCD CS/reset and the touch reset all sit on a TCA9535 at 0x20 on the SDA39/SCL40 bus, not on ESP32 GPIOs, so everything after this commit depends on the expander. The env gives the radio lines virtual pin numbers 0x40..0x43 for a radio HAL to map onto expander bits; until that HAL exists the radio is a plain Module that links but cannot drive the chip. The expander driver is header-only so a host test can cover it: - its output and config shadows are seeded from the chip, because a warm reset or the previous firmware may have left pins driven and writing the power-on defaults back would glitch the radio, panel and RP2040 resets; - a failed write rolls both shadows back to the last state written in full, and the next write brings the chip back in line with them; - polarity inversion is cleared when a previous firmware left it set, since it would invert BUSY, DIO1 and the strap; it is written only when it is not already 0; - every read of input port 0 is reported to an observer, so a DIO1 edge is not lost when another reader clears /INT. A five-sample majority of the P1.3 strap selects the TCXO (2.4 V) or crystal radio at run time, so one noisy read cannot pick the wrong oscillator. The expander, the touch driver and the display init serialise on one recursive mutex over the shared Wire bus (IndicatorIo::BusLock). It is a function-local static, so the compiler guards its creation when two tasks reach the first lock together. IndicatorIo::begin() logs the registers it inherited and names the step that failed, since a dead expander takes the panel and radio down with it and is otherwise silent. The board has 8 MB of flash. The partition table has one 4.5 MB factory app slot, a 3.375 MB SPIFFS (as on the 16 MB boards) and a 64 KB coredump, with no map tile partition. The factory slot is larger than the 0x3E0000 OTA slots of the 16 MB boards, so an image that fits those fits here. CAP_OTA is off: with one app slot there is no in-place update. CAP_BATTERY is 0: no battery is fitted. Montserrat 18/20/24 for the UI-size presets are the generated faces; the board joins their gate in ui_font_18/20/24.c, gen-touch-fonts.sh, hwFitFont and luaHostFigureFont. LVGL is built at -O2 with the Arabic and newlib-memcpy settings the other envs use. run-host-tests.sh builds every test/test_*.cpp, so the new expander test gets its include path there in the same commit. build-upload-monitor.sh gets --sensecap-indicator.

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.
