NW-Status

At-a-glance status of every NorthernWidget hardware design and firmware/software library across the current threads of work: bringing the libraries to a common form, the Schema 1 (NW-Device-Specification) rollout, and hardware readiness.

Status — 2026-09-24

Generated by nw_status.py from the working tree, git, the GitHub API, and NW-Device-Specification. Cells listed in nw_status_manual.csv are hand-maintained (Schema 1 firmware and library state, hardware verification, next actions, notes); everything else is scanned. Supersedes nw_library_audit_2026-05-15.csv.

One row per device (its library and its hardware repo together) or per unpaired library; rows are banded as Devices, Standalone libraries, and Bare repos. This file carries one table per thread of work; the master table with every column side by side is nw_status_2026-09-24_icons.pdf. A column in which every row passes or does not apply is hidden and listed under the table.

Legend: ✅ done · ◐ partial · ❌ missing or wrong · — not applicable · ? not determined

Common sensor API: goal is that every sensor library presents the same C++ interface in Arduino style. Facets, one column each: begin() returns bool; getHeader()/getString(); the raw-readings triad beginRawReadings()/takeRawReading()/endRawReadings(); casing in two steps, camelCase conversion (every method has a camelCase name and any PascalCase name still present is marked [[deprecated]]) then PascalCase removed (no PascalCase method remains; "pending" while deprecated aliases are still carried); header string has no trailing space; header separator (comma or comma-space, a fact rather than a check, since the target format is undecided). Whether every sensor must carry the raw triad is also an open decision.

Release readiness: columns follow RELEASING.md, one per required file or field.

Open items that are not per-row: spec appendices still print Magic=0x00 (spec body says 0x4E); NorthernWidget_Core and the NorthernWidget bundle library have no repo yet; Firmware-Aggregator repolist.txt still names BME_Library and MCP3421; Symbiont-LiDAR_Library is not cloned locally (superseded by Apis); Monarch/Dyson libraries are archived, split into Libelle and Liasis.

Use

python3 nw_status.py           # scan the workspace and GitHub, then render
python3 nw_status.py scan      # write nw_status_<date>.csv only
python3 nw_status.py render    # render the latest dated CSV into this README and to _icons.pdf

The NW repositories are expected in the parent directory of this one, or in $NW_WORKSPACE if set. Rendering the PDF needs Google Chrome; without it the Markdown and the intermediate HTML are still produced. GitHub queries use the gh CLI.

Where the testing lives

Two repositories beside this one carry the tests the table reports on. NW-Tests compiles every sensor library inside a Margay and an Okapi sketch and runs each library's desktop harness. NW-Sim (private) runs a logger's firmware on a simulated ATmega1284P with the board hung off it – clock, card, on-board sensors, rails and bus switch – and, since 2026-09-24, a sensor's own firmware on a simulated ATtiny1634 answering the logger's library over a simulated two-wire bus. Neither replaces the bench; both replace finding out on the bench.

What is scanned and what is hand-maintained

Almost every cell is derived from the working tree, git, the GitHub API, or the NW-Device-Specification text at scan time: required files, library.properties fields, tags, begin() return type, the common-API facets (including casing in two steps: camelCase conversion, then PascalCase removed), open and bug-labelled issues, uncommitted and unpushed state, design-file formats.

Cells that no scanner can read live in nw_status_manual.csv as Row,Column,Value and are merged over the scanned values: Schema 1 firmware and library state, hardware verification, next actions, notes. Edit that file when a hand-tracked state changes; rerun the scan for everything else.

Outputs

• nw_status_<date>.csv — one row per device (its library and hardware repo side by side) or per unpaired library; one fact or one check per column.
• the report below, written into this README between markers — one table per thread of work, rows banded as Devices / Standalone libraries / Bare repos; a column in which every row passes or does not apply is hidden and listed under the table. Git history of this file is the dated record.
• nw_status_<date>_icons.pdf — the master table with every column, group bands over the columns, one icon per cell (not committed; regenerate).

Dated CSV snapshots are committed so that the state on a given day can be recovered; the report itself lives below.

Archive

archive/ holds the May 2026 Library Manager readiness audits and their render script, which this tool supersedes.
