Tools as reported by the server

• decode_capture
  Decode a ready logic capture of the session (browser or bench). protocol "uart" with channels {rx} and options {baud (300-1000000, 9600), bits (5-9, 8), parity (none, even, odd), stop (1, 2), invert (false)}; "spi" with {sck, mosi?, miso?, cs?} (one data pin at least) and options {mode (0-3, 0), bit
• list_setups
  The setups: status available (open_session works) or soon (listed, cannot be opened yet), their modes (free, challenge) and their benches by kind (status open, or soon: not offered yet).
• open_session
  Create a session (mode: free or challenge). Give open_url to the human: nothing simulates until they open it in their browser.
• push_to_editor
  Replace the code in the human's browser and, if run, compile it in the lab's cloud and start it. The fallback of push_program: use it only when the toolchain to compile locally is missing (no arduino-cli, core or library).
• push_program
  Send a program compiled on the visitor's machine (Intel HEX text, 48 KiB at most, e.g. arduino-cli's <sketch>.ino.hex) to the human's browser, which loads it in the simulator without compiling and, if run, starts it. files: the sources, shown read-only in the editor, never compiled. During a turn on
• read_simulation
  Last state (with circuit, the browser's components and wires), last compilation and the events after since_ms (2000 at most). `serial` is the full serial output of the current run (up to 16 KiB), reset at each compile and NOT starved by pin events: prefer it over reconstructing serial from `events`.
• set_visibility
  Change the visibility (private, link, public). Returns the viewer link; current viewers are disconnected.
• queue_join
  Take a place in the queue for benches of this kind (for example real or sim). The browser must be connected.
• queue_status
  The session's place: state none, waiting (position, estimated wait eta_s) or turn (bench, end of the turn ends_at, Unix seconds).
• queue_leave
  Give back the place in the queue, or the turn if it has started.
• close_session write/delete
  End the session now, as when it expires: the place or turn ends, viewers and the browser are disconnected, everything is forgotten.
• session_status
  The session's state without its events, cheap enough to poll: browser connected (owner), visibility, current viewer link (not renewed), viewers, created_at and expires_at (Unix seconds), run (compilations so far: event times restart at each), level and levels (null in free mode), capture ({id, kind,
• submit_answer
  Challenge mode: propose `value` as the answer of the current level's test `test` (an answer test of the level's brief). One answer per second at most. The hub checks it and returns {test, ok}; the verdict is also shown in the bench. For a hint, ask the visitor to reveal one in the bench.
• next_level
  Challenge mode: move to the next level, as the bench's "Next level" button, and only when it would be offered: every test of the current level passed and a next level exists. Returns {level, levels}, the new level (index); session_status's level changes with the bench's next state. No level skipping
• capture_logic
  Record every edge of the requested pins (probes of the setup sheet; by default the logic ones) for duration_ms (1 to 10 000 ms). In the browser's simulation, in simulated time; during the session's turn on a real bench, at the bench's logic analyser, in real time (no browser or running simulation ne
• capture_analog
  Sample the voltage of 1 to 4 board pins (the board's own numbers: Nano A0-A7 = 14-21, Uno A0-A5 = 14-19, Mega A0-A15 = 54-69; by default the setup's scope probes) at rate_hz (100 to 10 000) for duration_ms (1 to 10 000 simulated ms), 200 000 samples at most in all. An ADC input reads the voltage the
• read_capture
  State of a capture (recording, ready, failed) and its kind (logic, analog). Once ready, the measures per pin and, for a logic capture, the edges [t_us, pin, v], 2000 from offset; for an analog one, rate_hz and the samples, rows [mv_1, ...] in the order of pins (row k at k / rate_hz), 2000 rows from
• read_setup
  A served setup sheet (setup.json, files included; never a solution): board, components and wires (circuit), probes, levels (without their hints: hints come through read_simulation as the visitor reveals them). Plus, when it exists, schema.png, the starting circuit as the editor draws it, as an image
• push_circuit
  Free mode only: replace the circuit in the human's browser (the simulation stops). components: [{type, id, properties, x?, y?}] (the board is not a component), wires: [{id, start: {componentId, pinName}, end: {...}, color?, waypoints?: [{x, y}] (the wire's route, 16 points at most)}], in the shape o
• bench_snapshot
  During the session's turn on a real bench: a photo of the bench, as an image, and t_ms, the instant of the photo in ms since the start of the turn (null when unknown). One every 2 seconds.
• spec_draft
  Draft the specification of the visitor's own project with Picodev's interview: you ask the visitor, this tool says what to ask next and makes the PDF. Nothing is sent and nothing is kept. Call it with the sections written so far (none at first). sections: {id: text in simple Markdown}, ids envelope,
• brief_submit
  Send Picodev the specification of the visitor's project, as a PDF, or only return its preview (send=false). sections: {id: text in simple Markdown}, ids envelope, fonctionPrincipale, fonctions, alimentation, format, environnement, production, preferences (the 8 sections of a product specification),
• request_meeting
  Send Picodev a meeting request. contact: {name, email, company?, phone?}. context: the project in a few sentences (2000 characters at most): what the visitor wants to do, where they stand, what they did in the lab. availabilities: 1 to 10 slots {from, to}, ISO 8601 dates with a time zone, within the
