The emulated BMI270 and battery gauge were faithful and inert: with nothing
driving them the IMU reported the board lying flat for the whole run and the
gauge reported the single voltage it was seeded with, so a sketch that reacts
to tilt or warns on low charge could not be exercised at all.
A Sensors popover on the canvas header supplies the missing half. Tilt is
entered as roll/pitch on a drag pad rather than three raw axes — what a user
means is "lean it left" — and gravity in the board's frame is that rotation
applied to (0, 0, 1) g, which is also why the vector stays at 1 g whatever the
attitude. Turning the board spins the gyro for as long as the drag lasts and
parks it back at zero shortly after, matching a real part: a held tilt reads no
rotation. Battery is a slider over the LiPo working range.
Gated per board by builtInImu / builtInBattery on the pro board def, the same
way the Mic toggle is gated, and each section renders only if its flag is set.
The microphone stream also learns to resample. The engine now tells the source
which rate the guest programmed, so a sketch recording at 8 kHz consumes two
captured samples per read instead of playing back at half speed.
New canvas-header Mic toggle, shown for boards whose ProBoardDef declares
builtInMicrophone (their bridge implements setMicrophoneSource). Capture
runs at the AudioContext's native rate, is decimated to 16 kHz and ring-
buffered (2 s, drop-oldest on overflow, silence on underflow - the engine
paces pulls in simulated cycles, up to 4x real time during boot boost).
No auto-start: with the toggle off the bridge's 440 Hz test tone keeps
mic sketches alive, so taking the user's microphone stays an explicit
click. The source is re-applied on every run start to survive bridge
rebuilds.
Seam nuevo registerBoardBuiltins/getBoardBuiltins: una placa que el arbol
OSS ya dibuja (la familia Pi) puede recibir perifericos del overlay sin
registrar un ProBoardDef, que es lo que secuestraba el arte de la placa y
dejaba los cables en la esquina. El overlay lo usa para llevar los frames
del guest (cv2.imshow) al panel cableado en el canvas.
Arregla ademas el guard de connect() del bridge: comparaba readyState con
WebSocket.OPEN leido del global, asi que cuando esas constantes no estaban
`undefined === undefined` era cierto con socket a null y connect() volvia
sin abrir nada — el bridge se quedaba muerto. Ahora comprueba que el socket
exista y usa el valor numerico. Recupera los 12 tests de
multi-board-integration que esto habia roto.
El test del UART Pi->Uno pasa a comprobar el contrato vigente: por el cable
va onUartTx (el UART del header), no la consola del guest; y se anade el
caso que fija que la charla de arranque NO se filtra al vecino.
Dos fallos que salieron probando pi-to-arduino-led-control y
pi5-pir-motion-alarm.
1) BoardOnCanvas mira getProBoard() ANTES del switch OSS para decidir si
dibuja un elemento del overlay. El overlay registraba un def minimo
para las seis Pi solo para llevar una linea de setup del guest, y eso
basto para cambiarles el render: en vez de la ilustracion
Raspberry_Pi_3_illustration.svg salia la caja esquematica, con otras
coordenadas de pines, y los cables quedaban colgando en la esquina.
Ahora hay un registro aparte, registerGuestSetup(kind, linea), que
lleva la cadena y nada mas; getGuestSetup() la resuelve dando
prioridad al def del overlay si existe.
2) Las partes de entrada (PIR, botones, sensores) avisan con
simulator.setPinState(pin, nivel). En una placa QEMU-Linux no hay
simulador de MCU -- el CPU es el guest -- asi que la llamada acababa
en la instancia AVR heredada y se perdia: pulsar el sensor no hacia
nada. traceDetailed devuelve ahora tambien la placa a la que llega el
pin, y si es de la familia Pi la parte recibe un simulador que empuja
el nivel al bridge (gpio_in para el guest, el valor pin<N> que leen
los shims del motor de navegador) y al PinManager de esa placa.
The generic arm64 image prints another product's banner/motd/login line
during boot, before guestSetup can re-brand the guest. Boards with
quietBoot show a neutral '[Velxio] Booting <label> (Linux guest)...'
progress line (dots every 4 s) while boot detection and the prompt-gated
upload still run underneath; the shell is revealed (already re-branded)
right before the auto-run command, so the user's first visible output is
their own program.
- ProBoardDef.autoRun: after boot (+guestSetup) the VFS uploads itself
and the command runs, so a single Run click boots, uploads and starts
the user's script (same UX as compiled boards)
- ProBoardDef.guestHome: VFS home dir override ('/root' for guests that
log in as root); those boards drop the historic hello.sh sample
- upload sequence extracted to utils/piUpload (shared by the VFS panel
button and autoRun)
- serial monitor strips DEL/C0 control echoes (backspace showed tofu)
Overlay QEMU-Linux boards are not Raspberry Pis: ProBoardDef.guestSetup
lets a board send one shell line at the boot prompt (hostname/PS1/clear)
to de-brand the generic image, sent before piBooted flips so uploads
cannot interleave; the workspace start button and power-on title carry
the board's own label for non raspberry-pi kinds; the compile console
line uses the board label instead of 'Raspberry Pi 3B'.
registerPiFamilyKind + ProBoardDef.piFamily route an overlay board through
the existing Raspberry Pi bridge path (WebSocket qemu, VFS panel, boot
terminal); register_pi_board_profile lets the overlay add the matching
PI_CONFIGS entry (cpu/image_set/...) at registration time.
The @pro overlay import is dynamic, so board/component registration can land
AFTER the picker mounted and memoized its lists. allBoards had frozen deps —
if the picker rendered first, overlay boards (M5Stack Core, Cardputer,
Pimoroni, C6) vanished for the whole session while their ONLINE ads were
already hidden; the component grid + ONLINE component ads flipped between ad
cards and real entries depending on who won the reload race (different SVG,
ONLINE badge appearing and disappearing, wrong hover thumbnail).
proBoardRegistry and ComponentRegistry.mergeComponents now bump a version and
notify subscribers; the picker's allBoards / filteredComponents /
visibleComponentAds memos key off those via useSyncExternalStore — same
contract as proRoutes and registerProExamples.
Boards with built-in hardware (LCD on the element's own canvas, speaker,
on-board buttons/keyboard) need run-time wiring between the DOM element and
the board's simulator shim / ESP32 bridge. One generic SimulatorCanvas effect
now hands those handles to the overlay's attachBuiltins shortly after run
start and runs its cleanup on stop — no board names in the OSS tree.
registerProBoards() lets a hosted overlay ship boards outside the OSS tree as
data-only definitions: registration patches the exported BoardKind maps
(labels / FQBN / MicroPython) so every existing read site keeps working, and
the sites a map can't cover consult the registry — canvas render (custom
element or overlay render fn), BOARD_SIZE, pin-name mapping, picker list +
descriptions + tag, ESP32 family routing, in-browser simulator construction
and firmware load (structural ProBoardSimulator contract, duck-typed PIO
attach/detach), built-in bridge sensors, and a CS-gated built-in microSD
(sdCsPin -> sd_card.cs_pin worker config). Esp32Bridge additionally gains the
esp32-c6 machine type + TX pin (public chip knowledge — the C6 compile path
already ships) and a generic sendKey() for built-in matrix keyboards.
registerProExamples() appends gallery examples at runtime; the board ONLINE
ads recompute at render so registration hides them. OSS behavior without an
overlay is unchanged — the registry is dead code, same as the other seams.
