M5Stack makes three Cardputers and only the Zero runs Linux; the PicoCalc takes several cores and only the Luckfox Lyra runs MeshTerm. So the bare names were ambiguous, and every reference to the two devices now carries the variant: the --platform values and MESHTERM_PLATFORM, the Platform constants (PICOCALC_LYRA, CARDPUTER_ZERO), their lane decks and every screen's picocalc_lyra_lane / cardputer_zero_lane, the font inventories, the lane chips' theme styles, the scripts/ folders, the two chrome test files, and the docs and CLAUDE.md that name them. There is no alias: --platform picocalc is refused with the three real choices listed, rather than falling back to the desktop layout. The PicoCalc is auto-detected from its device tree, so it needs nothing. What names hardware or a user's data keeps its name: the PicoCalc keyboard's input-device name, its battery's sysfs supply, and the serial profile the Lyra setup script writes. .gitignore follows the firmware's folder, and the changelog keeps the words each release used.

"""Fetch the Terminus 12-pixel BDF fonts the Cardputer console host draws in.
|
|
|
|
Terminus is licensed under the SIL Open Font License, so MeshTerm never ships it: this
|
|
downloads the upstream release, checks it is the archive it should be, and extracts
|
|
``ter-u12n.bdf``, ``ter-u12b.bdf`` and the licence beside them into the directory the host
|
|
reads (``$MESHTERM_HOST_FONTS``, else ``fonts`` under the MeshTerm config directory).
|
|
|
|
Run it once on a machine that will run the host or its desktop simulator:
|
|
|
|
python scripts/cardputer-zero/fetch-terminus.py
|
|
|
|
Where Python can't fetch it (a certificate store that rejects the mirror), download the
|
|
archive any other way and hand it over; it is checked against the same digest:
|
|
|
|
python scripts/cardputer-zero/fetch-terminus.py --archive terminus-font-4.49.1.tar.gz
