Enter on a picture shows it: shrunk to fit the screen, or at its own size with Enter again and the arrows to move. Dithered to the screen's 256 colours; a colour the screen has exactly is left alone, so screenshots are shown as they are. The picture is decoded once, straight into the screen's buffer, and kept there (App::retainsContent): no copy in memory. Decoding runs on the storage task, so the keys keep working and a 12 megapixel photograph appears as it comes instead of tripping the watchdog. PNG, BMP and GIF are read by decoders of our own, host-tested against files made by Pillow; the PNG one needs 32 KB where the display library's needed 44 KB in one block, which the device often doesn't have. JPEG uses the library's TJpgDec. Also corrects two sentences that still gave 16 KB as the editing limit.

The roro9stack site
Source of https://roro9stack.net (docs/milestones/W1.md): a Zola site. The home page, an Install page with a browser flasher, and the list of releases so far; the user guide, how-tos, FAQ and developer docs come next.

Build and look
docker run --rm -u "$(id -u):$(id -g)" -v "$PWD:/repo" -w /repo/site ghcr.io/getzola/zola:v0.22.0 build # writes ./public
docker run --rm -u "$(id -u):$(id -g)" -p 1111:1111 -v "$PWD:/repo" -w /repo/site ghcr.io/getzola/zola:v0.22.0 serve --interface 0.0.0.0
python3 site/tools/check_site.py public # what the pages promise, kept
Or zola build with a Zola of your own, in site/ (or zola --root site build from the root). The output goes to public/ at the root of the repository, not into site/: output_dir in config.toml, and git ignores that directory. The build reads the latest release and the list of releases from the Gitea API (load_data); if the server can't be reached, the pages say so instead of failing.
Publishing
The web server pulls main and runs zola build, as for the blog. CI (.gitea/workflows/site.yml) builds the site and runs the checks when site/, docs/, README.md or CONTEXT.md change; the firmware workflow skips a change that touches only those.
Things to know
-
The Install page needs Caddy's help. Gitea's release downloads carry no CORS header, so the page asks the API from the browser only if Caddy, in front of Gitea, allows this origin:
@releases { method GET HEAD path /twisla/roro9stack/releases/download/* /api/v1/repos/twisla/roro9stack/releases* } header @releases Access-Control-Allow-Origin "https://roro9stack.net" header @releases Vary OriginWithout it the page says it can't reach the release server and points to the esptool steps.
-
No third-party requests. Fonts and the flasher library are served from here;
tools/check_site.pyfails the build if a page loads anything from another origin. -
Illustrations.
