Built-in setup page
Backup / restore settings.json together with the pin map
as a single file — import it here after a web flash to re-provision the device in
one step. The Wi-Fi password is not included (it is stored
separately, outside settings.json) — set Wi-Fi above. A full power
cycle is needed after import.
Upload an application image — atlascube.bin, or
AtlasCube-<display>-ota.bin for your display from
atlascube.net/flash.
It is written to the inactive slot and the device reboots into it; settings and
pin map are kept. Works from this built-in page even if the web UI partition is wiped.
Don't power off during the upload.
www_version.txt in the selection to clear this warning.
Get the matching files (AtlasCube-www.zip) from the
latest GitHub release, then extract and
upload them below.
Optional / recovery only — the web UI ships inside the firmware, so a normal flash already includes it. Use this just to patch or restore individual files without reflashing.
Pick the files from spiffs_image/www/ (raw, uncompressed) —
get the matching set (AtlasCube-www.zip) from the
latest release.
The device gzips HTML/CSS/JS on upload. Icons (.ico) are not supported here.
Include www_version.txt to clear the "web UI out of date" warning.

Allowed pins (in use / free):
GPIO number per signal, or -1 to disable. The display
driver is fixed in this firmware — only the wiring is configurable here.
Reserved 26–37 (flash/PSRAM) and duplicates are blocked; strapping (0/3/45/46)
and native-USB (19/20) pins are flagged but allowed; 43/44 are the UART0
console (avoid unless you don't need serial logging). Saved values take effect
after the restart.
