twislaandClaude Opus 5.5 37335b4829 UI: seven themes, each dark and light, chosen in the Settings
Settings > Theme and Settings > Light or dark pick the colours of every
screen (issue #10): roro9stack (the website's, the default), Catppuccin,
Dracula, Nord, ANSI terminal, Gruvbox and Solarized.

- A palette is 14 roles (lib/ui/src/palette.h). theme::kText and the
  others are now references into the one in use, so the Apps are
  unchanged; the main loop applies it when a Setting changes.
- Every colour is one the RGB332 frame buffer holds exactly: the themes'
  own were rounded, and those that fell together or lost contrast were
  picked by hand. test_palette checks exactness and 18 contrast ratios
  for each palette.
- The Sky view's constellation colours come from the theme.
- `theme [0-6] [light|dark]` on the consoles.

Move with the arrows. On a toggle, a choice or a slider, left and right change the value; Enter opens a text field or a list of choices, or a page marked >. Back leaves.

Setting What it is
Long name, Short name The names you gave in the first-start Setup (up to 39 bytes, and up to 4 characters)
Region The regulatory region; EU868
Timezone For the clock and the dates in file names
Brightness A slider
Dim after, Screen off after Screen timeouts. Dimming must come before the screen turns off
Launcher The home screen as a Grid of icons or a List of names (see The basics)
Theme The colours of every screen: roro9stack (the website's), Catppuccin, Dracula, Nord, ANSI terminal, Gruvbox or Solarized
Light or dark Which side of the theme: every one has both
Sound & LED The beep and the flash on a Toast
GNSS Switches the receiver on and off (see GNSS)
Pause GNSS for LoRa Puts the receiver on standby while the radio listens (see LoRa Scanner)
Coordinates Decimal degrees, or degrees, minutes and seconds
Wi-Fi The page below
Check for updates Once a day, see Updates
Firmware The page described in Updates
VPN A WireGuard tunnel: its switch, "Start with Wi-Fi", and importing its configuration from the card. See VPN
Debug Console Off unless you switch it on. It lets a PC on the same network read the device's console and drive it, with a token shown on this page: see the developer docs. Leave it off if that means nothing to you
About The firmware version, the node number, battery, memory, uptime, clock and licence

Wi-Fi

Wi-Fi on its own page switches the radio on and off. The page also has:

  • Status: whether it is searching, joining, or connected, and to what.
  • Add a network: scans, lets you pick one, and asks for the password (leave it empty for an open network). Add a hidden network asks for the name first.
  • DNS and NTP: see below.
  • Your saved networks. The device joins one on its own whenever it is in range, the strongest first. Enter on a network opens its page.

An address by hand

A network normally gives the device its address by itself (DHCP, Automatic). On a network without DHCP, open its page and set IP address to Fixed: then it takes an address, a prefix (24 is 255.255.255.0) and an optional gateway. Switching to Fixed starts from what the network is giving the device at that moment, and the setting is checked and applied when you leave the page. IPv4 only. Forget this network is on the same page.

DNS and NTP

Two DNS servers (9.9.9.9 and 1.1.1.1 by default), used on Fixed networks, or on every network if Always use my DNS is on; and two NTP servers (pool.ntp.org and time.cloudflare.com), used after any that the network's DHCP offers. Enter on Status shows what is in use and where each value came from.

The keys, as the device lists them

What Fn + h shows on these screens. These tables are generated from the firmware's own lists, so they are always the current ones.

{{ keys(scopes=["settings", "settings-choice", "wifi", "wifi-servers", "wifi-network", "wifi-status", "wifi-scan", "wifi-name", "vpn", "debug-console"]) }}

Themes

A theme changes the colours and nothing else: the fonts and the layout stay. It applies at once, to every App, and is kept across restarts.

The screen shows 256 colours, so a theme here is the nearest the screen can do to the palette it is named after, not an exact copy: pale backgrounds turn white or cream, and dark ones turn a deep blue or olive. Each theme is checked for contrast after that rounding.

Three things keep their own colours whatever the theme: the SSH terminal (the 16 colours a remote program asks for), the Sweep's waterfall (its colours are a scale of signal strength), and pictures.
