Finished Tamafi Smart Virtual Pet Firmware Version V2.0 ESP32-S3 Wifi Interactive Virtual

TamaFi is a modern, WiFi-aware virtual pet. V2 rebuilds the original project with new hardware, smarter logic, and a clean, compact PCB that actually feels like a finished device. The pet lives on an ESP32-S3, eats nearby WiFi, evolves over time, and makes its own decisions based on the environment around it. ✨ Highlights (V2) ⚙ ESP32-S3 based – more performance, native USB, better room for future features 🖥 TFT ST7789 240×240 – full-color UI, custom sprites, status bars, menus 🧠 Autonomous behavior engine – the pet hunts, explores, rests, and reacts on its own 📶 WiFi-fed – nearby networks affect hunger, happiness, and health 🎛 Full menu system – Pet Status, Environment, System Info, Controls, Settings, Diagnostics 💾 Persistent state – age, stats, stage, settings stored in flash (Preferences) 🌈 4× WS2812-2020 NeoPixels – mood & activity feedback (happy/sad/wifi/rest patterns) 🔊 Retro sound engine – non-blocking chiptune-style beeps and sequences 🖱 6 soft tactile switches – three on each side for navigation and shortcuts 🛠 DisplayKit-ready UI workflow – UI graphics can be designed/exported via DisplayKit 🧩 How TamaFi V2 Behaves TamaFi isn’t just a sprite animation loop. It runs a small decision engine that constantly evaluates: Pet stats:,, hungerhappinesshealth Traits: curiosity, activity, stress Environment: number of nearby networks, open/hidden networks, average RSSI Time: age (minutes → hours → days) From that, it decides whether to: 🍖 Hunt – use WiFi scan results to “feed” and adjust hunger/happiness/health 👁 Explore – react to open/hidden networks and network diversity 😴 Rest – enter a sleep cycle with special egg animation and recovery stats 😐 Idle – chill on the home screen with mood-based idle animations Mood system The pet mood changes based on stats + environment: HUNGRY – low hunger HAPPY – good stats + decent WiFi CURIOUS – hidden/open networks nearby BORED – no WiFi for too long SICK – low health or bad conditions EXCITED / CALM – good conditions & variety Mood affects: Idle animation speed LED patterns How often it wants to hunt / explore / rest Evolution Age is tracked in minutes, hours, and days: BABY → → → TEENADULTELDER Evolution depends on: Time alive Average of hunger / happiness / health Environment quality Reaching a new stage triggers special SFX + animations. 🖥 UI & Menu System All rendering goes through a 240×240 framebuffer ( + ) to avoid flicker.TFT_eSPITFT_eSprite Home Screen Pet sprite (idle / hunt / rest / special states) Background image Stats bars: Hunger, Happiness, Health Mood + Stage text Activity label in the top bar (,,, etc.)IdleHunting…Resting… Overlays for special effects (e.g. hunger effect) Menus Navigation is done using the left 3 buttons (UP / OK / DOWN). Main Menu: Pet Status – stats, mood, age, stage, short description Environment – WiFi network counts, hidden/open, “signal mood” System Info – firmware version, uptime, battery (if implemented), etc. Controls – brightness, LED level, sound on/off, NeoPixel on/off Settings – auto-sleep, auto-save interval, soft reset options Diagnostics – debug info, test modes (non-destructive) Back to Home Changes in Controls/Settings are saved to NVS via, so they persist across reboots.
