<h1>Project Architecture</h1>
<p>
Velxio is a fully local Arduino emulator using official Wokwi repositories for maximum
compatibility. It features real AVR8 CPU emulation, 48+ interactive electronic components,
a comprehensive wire system, and a build-time component discovery pipeline.
</p>
<h2>High-Level Overview</h2>
<pre><code>{`Browser (React + Vite)
Monaco Editor useEditorStore (Zustand)
SimulatorCanvas useSimulatorStore (Zustand)
AVRSimulator (avr8js) 16 MHz AVR8 CPU
RP2040Simulator (rp2040js)
PinManager pin component mapping
PartSimulationRegistry 16 interactive parts
48+ wokwi-elements Lit Web Components
HTTP (Axios) FastAPI Backend (port 8001)
ArduinoCLIService arduino-cli subprocess`}</code></pre>
<h2>Data Flows</h2>
<h3>1. Compilation</h3>
<pre><code>{`Click "Compile"
EditorToolbar reads all workspace files
POST /api/compile/ { files, board_fqbn }
Backend: ArduinoCLIService writes temp dir
arduino-cli compile --fqbn <board> --output-dir build/
Returns hex_content (Intel HEX string)
useSimulatorStore.setCompiledHex() loadHex()`}</code></pre>
<h3>2. Simulation Loop</h3>
<pre><code>{`Click "Run"
AVRSimulator.start()
requestAnimationFrame loop @ ~60 FPS
Each frame: Math.floor(267 000 × speed) cycles
avrInstruction(cpu) decode + execute one AVR instruction
cpu.tick() advance Timer0/1/2, USART, ADC
PORTB/C/D write listeners fire
PinManager.updatePort() per-pin callbacks
PartSimulationRegistry.onPinStateChange()
wokwi-elements update visually`}</code></pre>
<h3>3. Input Components</h3>
<pre><code>{`User presses button on canvas
wokwi web component fires 'button-press' event
DynamicComponent catches event
PartSimulationRegistry.attachEvents() handler
AVRSimulator.setPinState(arduinoPin, LOW)
AVRIOPort.setPin() injects external pin state
CPU reads pin in next instruction`}</code></pre>
<h2>Key Frontend Stores (Zustand)</h2>

<h2>Wire System</h2>
<p>Wires are stored as objects with start/end endpoints tied to component pin positions:</p>
<pre><code>{`{
id: string
start: { componentId, pinName, x, y }
end: { componentId, pinName, x, y }
color: string
signalType: 'digital' | 'analog' | 'power-vcc' | 'power-gnd'
}`}</code></pre>
<ul>
<li>Orthogonal routing no diagonal segments</li>
<li>Segment drag drag perpendicular to segment orientation</li>
<li>Auto-update wire positions recalculate when components move</li>
<li>Grid snapping 20 px grid for all wire endpoints</li>
</ul>

<h1>Wokwi Libraries</h1>
<p>
Velxio uses official Wokwi open-source repositories cloned locally in <code>wokwi-libs/</code>.
This gives you up-to-date, compatible emulation engines and visual components without npm registry
dependencies.
</p>
<h2>Cloned Repositories</h2>
<table>

<tr>
<td><a href="https://github.com/wokwi/wokwi-elements" target="_blank" rel="noopener noreferrer">wokwi-elements</a></td>

<h2>Vite Configuration</h2>
<p><code>frontend/vite.config.ts</code> uses path aliases so imports resolve to the local builds:</p>
<pre><code>{`resolve: {
alias: {
'avr8js': '../wokwi-libs/avr8js/dist/esm',
'@wokwi/elements': '../wokwi-libs/wokwi-elements/dist/esm',
},
}`}</code></pre>
<h2>Updating the Libraries</h2>
<h3>All at once (recommended)</h3>
<pre><code>{`# Windows
update-wokwi-libs.bat`}</code></pre>
<h3>Manually</h3>
<pre><code>{`cd wokwi-libs/wokwi-elements
git pull origin main
npm install && npm run build
cd ../avr8js
git pull origin main
npm install && npm run build
cd ../rp2040js
git pull origin main
npm install && npm run build`}</code></pre>
<h3>After updating wokwi-elements</h3>
<p>Regenerate component metadata so new components appear in the picker:</p>
<pre><code>{`cd frontend
npx tsx ../scripts/generate-component-metadata.ts`}</code></pre>
<h2>Available Wokwi Components (48)</h2>
