Roadmap

This document lists the features that are implemented, in progress, and planned for future releases of Velxio.

✅ Implemented

Editor

  • Monaco Editor with C++ syntax highlighting, autocomplete, and minimap
  • Multi-file workspace — create, rename, delete, and switch between .ino, .h, .cpp files
  • Unsaved-changes indicator on file tabs
  • Resizable file explorer panel

Compilation

  • Arduino compilation via arduino-cli backend
  • Multi-file sketch support
  • Compilation console with full output, warnings, and errors

Simulation — AVR (Uno / Nano / Mega)

  • Real ATmega328p / ATmega2560 emulation at 16 MHz via avr8js
  • Full GPIO: PORTB (8–13), PORTC (A0–A5), PORTD (0–7)
  • Timer0/1/2 — millis(), delay(), analogWrite()
  • USART — Serial transmit and receive
  • ADC — analogRead() on A0–A5, voltage injection from potentiometers
  • SPI — ILI9341 TFT display
  • I2C (TWI) — virtual device bus

Simulation — RP2040 (Raspberry Pi Pico)

  • Real RP2040 emulation at 133 MHz via rp2040js
  • UART0 serial output in Serial Monitor
  • 12-bit ADC on GPIO 26–29

Components

  • 48+ wokwi-elements components
  • Component picker with search and category filters
  • Drag-and-drop repositioning
  • Component rotation (90° increments)
  • Property dialog (pin assignment, rotate, delete)

Wire System

  • Click-to-connect wire creation
  • Orthogonal routing (no diagonal paths)
  • 8 signal-type color codes
  • Segment-based wire editing (drag segments)

Serial Monitor

  • Live serial output
  • Auto baud-rate detection
  • Send data to Arduino RX

Library Manager

  • Browse and install the full Arduino library index
  • Live search, installed-tab, version display

Auth & Projects

  • Email/password and Google OAuth sign-in
  • Project save, update, and delete
  • Permanent project URLs (/project/:id)
  • User profile page (/:username) with public projects

Example Projects

  • 8 built-in examples: Blink, Traffic Light, Button Control, Fade LED, Serial Hello World, RGB LED, Simon Says, LCD 20×4

Deploy

  • Single-container Docker image (GHCR + Docker Hub)
  • GitHub Actions CI/CD pipeline

🔄 In Progress

  • Functional wire connections — electrical signal routing and validation
  • Wire connection error handling — detect short circuits and invalid connections

🗓 Planned

Near-Term

  • Undo / redo — for code edits and canvas changes
  • Export / import projects as .zip files
  • More boards — ESP32, Arduino Nano, Arduino Leonardo
  • Breadboard — place components on a virtual breadboard with automatic wire routing

Mid-Term

  • TypeDoc API documentation — auto-generated from source code
  • GitHub Pages docs site — automatic deployment on push to main
  • More sensor simulations — HC-SR04 (ultrasonic), DHT22 (temperature/humidity), IR receiver
  • EEPROM emulation — persistent read/write across simulation restarts
  • Oscilloscope component — plot analog pin voltages over time

Long-Term

  • Multiplayer — share and co-edit simulations in real time
  • Embedded tutorial system — step-by-step guided projects inside the editor
  • Custom component SDK — define new components with a JSON/TypeScript API
  • Mobile / tablet support — responsive layout for touch devices
