Site / build (pull_request) Successful in 8s
Site: the user guide (phase 2): the basics, one page per App, Settings and Updates
Eleven pages under /guide/, written from the README, the milestone documents
and the Apps' own source: the keys, the Launcher, the Status Bar and the first
start; the LoRa Scanner, GNSS, Gemini, IRC, Wi-Fi tools, Notes, Storage and
System; Settings (with Wi-Fi) and Updates. Real screenshots where the site has
them, a Guide link in the navigation, and the home page points to it.

System changes nothing: it shows. It samples once a second and keeps its history only while it is open. Tab moves between five views.

  • Overview: each core's load, free memory, network traffic, battery, uptime and chip temperature, and both cores' load over the last two minutes.
  • Tasks: every task the system runs, with its core, its share of a core over the last second, and the least stack it ever had left (in the warning colour under 512 bytes). s sorts by share, stack or name.
  • Memory: free memory, the lowest since start, and the largest free block, with two minutes of free memory drawn against the three memory floors (55, 40 and 20 KB).
  • Network: the connection, then for IRC, Gemini, the debug console and firmware updates the bytes read and written since start, and what is moving now. For secure connections these are the bytes the service sees, without the encryption overhead.
  • System: the firmware version, uptime, the last start reason, memory, Wi-Fi, the battery, the SD card with its write faults, the radio and the GNSS receiver.

Why it exists

The device has about 107 KB of free memory and no PSRAM, so memory is the resource that decides what can run together: a secure connection takes about 52 KB at its peak. System makes that visible, and is how the project measures its own changes.
