- Implemented `i2c-esp32-real-firmware.test.ts` to test ESP32 I2C communication via backend and WebSocket.
- Created `load-example-transitions.test.ts` to ensure proper loading of examples between board-less and board-based contexts.
- Added `CircuitVerificationModal.tsx` to display circuit verification results before running simulations.
- Developed `circuitVerifier.ts` to perform pre-flight checks for circuit safety, identifying potential issues like short circuits and component overloads.
- Introduced minimal ESP32 I2C master sketch `esp32_i2c_writer.ino` for testing I2C transactions.
- Implement HD44780Decoder for decoding I2C commands to HD44780-compatible LCDs.
- Add bmp280_bridge_reader.ino to read BMP280 chip_id and status registers via I2C.
- Create i2c_scanner_multi.ino to scan I2C addresses and report responding devices.
- Introduce lcd_i2c_hello.ino to demonstrate basic LCD functionality with I2C.
- Implement pcf8574_bidirectional.ino to test bidirectional communication with PCF8574.
- Add pico_i2c_master_reader.ino for reading BMP280 from a Raspberry Pi Pico.
- Create rtc_lcd_clock.ino to display time from a DS1307 RTC on an I2C LCD.
components-metadata.json is shaped { version, components: [...] }, not a
flat array. The previous test assumed the latter and crashed on
default.find at module load on master, breaking CI for every PR.
Closes the loop on the four ESP32 fixes that landed earlier in this
series. Each previously-broken or noisy example now has a regression
test that compiles the sketch through the production ESP-IDF compiler
and runs it in QEMU via esp32_worker.py — the same code path the
WebSocket /ws/{client_id} endpoint drives in production. Testing the
worker directly skips the WS transport but exercises the same compile
→ flash → boot → serial cascade.
Coverage:
- TestEsp32SerialCleanliness — DHT22, Servo+Pot, Joystick, Dual ADC
Asserts the user's Serial.print substring shows up AND no
`I (xxx) gpio:|wifi:|phy:` info-level ESP-IDF logs leak through.
This validates the sdkconfig CONFIG_LOG_DEFAULT_LEVEL_WARN change
from commit b373c97.
- TestEsp32CompileSuccess — BLE Advertise, LEDC RGB
BLE Advertise validates the sdkconfig switch to Bluedroid (was
NimBLE-only, which broke arduino-esp32's BLEDevice.h).
LEDC RGB validates velxio_compat.h's ledcAttach() shim from
commit f6f6f43; the sketch uses the arduino-esp32 3.x one-shot API
on a 2.0.17 toolchain.
- TestEsp32WiFiSketches — WiFi Connect, WiFi WebServer
Regression coverage to make sure the sdkconfig changes didn't break
WiFi association. Connect must reach an "IP Address:" line; Server
must report "Server started".
- frontend/src/__tests__/component-metadata-bmp280.test.ts
Sanity check that the BMP280 entry from commit 1f3f2e0 survives
metadata regeneration.
All ESP-IDF/QEMU tests use unittest.skipUnless on
_toolchain_available() so they no-op cleanly on dev boxes without
libqemu-xtensa, and only do real work in the Docker CI image.
Sketches are inlined verbatim from the public Velxio examples.

Adds the foundation for canvas undo/redo. UI wiring, keyboard shortcuts,
toolbar buttons and agent-tools refactor land in follow-up commits.
useSimulatorStore.ts:
- New CanvasCommand type — { description, execute, undo }.
- HISTORY_MAX = 50 (oldest entries dropped on overflow).
- New state: history[] + historyIndex (-1 = empty).
- New APIs: pushCommand(cmd, {applyNow?}), undo, redo, canUndo, canRedo,
clearHistory.
- New "recorded" actions that wrap raw mutators with a CanvasCommand:
recordAddComponent, recordRemoveComponent, recordMove, recordRotate,
recordSetProperty, recordAddWire, recordRemoveWire, recordUpdateWire.
- recordRemoveComponent captures both the component AND any wires that
cascade with it, so undo restores both atomically.
- recordMove also re-runs updateWirePositions on undo/redo so wire
endpoints follow the component back/forward.
- setComponents and setWires (project-load / clear paths) now call
clearHistory inline — leaving stale commands pointing at IDs that no
longer exist would crash on undo.
Why custom Command pattern over zundo / travels:
- The store has 30+ ephemeral fields (simulator instances, serialOutput
growing byte-by-byte, hexEpoch counter, wireInProgress that ticks 60×/s
on drag). Snapshot/diff middleware would either burn memory tracking
them or need a fragile partialize allow-list.
- Per-op descriptions ("Add LED", "Move resistor") for tooltips come for
free with this approach; zundo/travels would need to infer them.
Tests: 15/15 in src/__tests__/undo-redo.test.ts — covers cap-at-50,
redo-truncation, cascade undo of remove-component, move/rotate/property
round trips, bulk-setter clearing.
Raw mutators (addComponent / removeComponent / updateComponent / addWire /
removeWire / updateWire) are unchanged. UI handlers can keep using them
during live drags for preview frames without spamming history; the
record* actions are what drag-end, click-finish and agent tools should
call going forward.

The directory grew well beyond Wokwi-only contents: it now hosts
lcgamboa's QEMU fork (qemu-lcgamboa), Espressif's esp32-camera, the
ngspice WASM build, fritzing-parts, picowi, an alternative QEMU
(qemu-esp32), the 100_Days_100_IoT_Projects examples repo, and
Wokwi's own avr8js/rp2040js/wokwi-elements/wokwi-features/wokwi-boards.
"wokwi-libs" was misleading — half the contents have nothing to do
with Wokwi. "third-party/" is the standard convention for vendored
external dependencies.
Mechanical changes:
Path rename:
wokwi-libs/ → third-party/
update-wokwi-libs.bat → update-third-party.bat
docs/WOKWI_LIBS.md → docs/THIRD_PARTY.md
Submodule reconfiguration:
.gitmodules — 4 path= and section names updated
.git/modules/wokwi-libs/ → .git/modules/third-party/
each submodule's .git file rewired to ../../.git/modules/third-party/<name>
Reference updates (~80 files): vite.config.ts aliases, Dockerfile
COPY paths, GH Actions workflow steps, build_qemu_*.sh, all
docs/* and test/*/autosearch/* entries that mention the path,
package-lock.json file: dependencies, .gitignore patterns,
sitemap.xml + index.html SEO blurbs, scripts/generate-component-*,
.dockerignore, .idea/vcs.xml. Bulk replaced both `wokwi-libs/`
(path) and bare `wokwi-libs` (textual mentions in docs/comments).
Verified:
- npx tsc -b --noEmit produces no new errors related to these paths
- vite.config.ts aliases now point at ../third-party/avr8js etc.
- All 4 git submodules (avr8js, rp2040js, wokwi-elements,
wokwi-features) are linked under third-party/ with their
worktrees re-populated and config files referencing the new path
- `grep -r wokwi-libs` returns zero hits outside node_modules,
.vite, frontend/dist, third-party/ (upstream submodule contents),
*.pyc caches, and *.dll.pre-camera rollback binaries

CI's Frontend Tests workflow had been failing on master for ~15 runs.
Two pre-existing issues, neither related to the SPI refactor in 8b1433d
or the ESP32-CAM work:
1. RP2040Simulator mock missing attachCyw43 method (23 test files)
PR #126 (8e769f8 "feat(multi-board): add wire-aware cross-board
interconnect router", merged 2026-04-25) added a Pico-W-specific
`sim.attachCyw43(bridge)` call inside addBoard(). The 23 test files
that mock RP2040Simulator with vi.fn weren't updated; whenever a
test path created a Pico W board the mock threw "TypeError:
sim.attachCyw43 is not a function" and aborted addBoard.
Fix: add `this.attachCyw43 = vi.fn()` to every affected mock.
Also pre-populate `this.spi = { onByte: null, completeTransfer: vi.fn() }`
so any future SPI-part tests don't trip on the new generic .spi
adapter from 8b1433d.
2. install-libraries.test.ts payload mismatch
PR #135 (b1026ec7 "library-version-uninstall", merged 2026-04-29)
extended `installLibrary(name)` to `installLibrary(name, version?)`
and now sends `{name, version: version ?? null}` over the wire.
The test still asserted `{name}` only and failed.
Fix: assert `{name, version: null}` for the no-version call.
Verified locally: 1161 passed | 1 skipped (was 1117 passed | 44 failed).
Backend E2E "Run HC-SR04 e2e test" is a separate failure that needs
its own investigation — it downloads QEMU binaries from a release and
runs real firmware compilation, which I can't reproduce on Windows.

Fixes the user-reported bug where two RPi Pico W boards wired GP0↔GP1
running SerialPassthrough don't communicate. Replaces the broken
broadcast-style cross-board logic in addBoard (only routed AVR↔Pi3B,
ignored wires entirely, no RP2040↔anything path) with a wire-aware
Interconnect singleton.
Architecture: digital pin transitions are the lowest-common-denominator
abstraction. Each simulator's hardware peripherals (UART/I2C/SPI) and
bit-banging libraries (SoftwareSerial, software I2C) decode the
transitions naturally — propagate the pin and the protocols come for
free. For cross-process boards (ESP32 backend QEMU, Pi3B QEMU) a
byte-level shortcut is additionally enabled on hardware-UART pin
pairs to handle high-baud links over WebSocket latency.
Implementation:
- New simulation/Interconnect.ts singleton subscribes to wire/board
changes via the Zustand store. Handlers per tier: browser-sim →
pinManager.onPinChange, ESP32 → Esp32Bridge.sendPinEvent, Pi3B →
bridge.sendPinEvent. Re-entrancy guard via per-(board,pin) Set.
- New utils/boardProtocols.ts classifies pins (uart-tx, i2c-sda, etc.)
per board kind, used as optimization hint for the byte shortcut.
- types/wire.ts: added signalType field, exports WireSignalType /
WireColorMap (fixes a pre-existing TS import error in wireColors).
- Deleted the bridgeMap/simulatorMap broadcast forEach blocks in
addBoard. Initial board + future boards register with Interconnect
via setInterconnectRuntime + store subscription.
- PinManager.resetPinStates() helper for test isolation.
Tests (16 new files, 96 tests, all passing):
- Per-pair × per-protocol matrix: dual-arduino-digital,
dual-pico-digital, arduino-pico-digital, triple-pico-digital-chain,
dual-arduino-hw-uart, dual-arduino-software-serial,
arduino-pico-mixed-uart, arduino-esp32-uart, dual-esp32-uart,
pi3-pico-uart, arduino-pico-i2c, arduino-arduino-spi,
interconnect-routing, dual-arduino-multi-protocol (UART+I2C+SPI+
digital + concurrent), dual-pico-multi-protocol (UART0+UART1 alt+
I2C0+I2C1+SPI0+digital + 3-Pico star topology)
- Updated dual-pico-serial-passthrough to assert correct behaviour
- Backend test/multi_board_esp32/test_dual_esp32_serial.py for two
real QEMU instances (skip-graceful when lcgamboa lib absent)
Verified: 1107/1107 tests pass, zero regressions, vite build OK.

fix: increase timeout for compilation requests to 180 seconds
refactor: call recalculateAllWirePositions after loading examples
chore: update subproject commit for rp2040js to dirty state
chore: update subproject commit for wokwi-elements to dirty state
Previously examples.ts pushed to exampleProjects[] after declaration, which
some bundlers can treat as dead code under aggressive tree-shaking. This
also made HMR unreliable when examples-circuits.ts changed.
Now:
const legacyExamples = [...]
export const exampleProjects = [...legacyExamples, ...circuitExamples]
Single immutable export. Guaranteed to include all 150 examples at import
time. The gallery (ExamplesGallery.tsx) and SSR prerender (entry-server.tsx)
both pick up the new circuit examples automatically.
Also adds frontend/src/__tests__/examples-circuits.test.ts with 5 assertions
to catch future regressions (all circuit ids present, no duplicates, valid
required fields, expected categories covered).
