Display & UI

LVGL GUI on ILI9341 320×240, ST7789V 320×240, ST7796U 480×320, ILI9488 480×320 TFT, CO5300 240×296 AMOLED, or SSD1322 256×64 mono OLED — selected at compile time
Clock, radio, playlist, EQ, settings screens
Audio VU meter — real-time FFT spectrum on the radio screen
Analog needle VU — two independent L/R needle meters overlaid on the wallpaper, so meter faces can be part of the background image
Stereo bar VU — two L/R bars with optional peak-hold, placed and coloured per screen
Dark and light themes
Rotary encoder + capacitive touch (CST816D or FT6336U) or resistive touch (XPT2046)
Push-buttons with configurable actions — up to ten buttons, each wired straight to a GPIO and GND with no extra parts. Short and long press are separate actions, so ten buttons cover twenty commands: playback, volume, mute, source switching, jumping to a screen, or menu navigation for a build with no rotary encoder at all. Pick the pins on the setup page, pick the actions in the web UI
180° flip, colour inversion and independent touch orientation — all live from the web UI, for panels mounted upside-down or wired differently
Swipe gestures to switch screens; swipe-up opens settings / playlist
Tap-to-show on-screen controls overlay (play/pause, vol±, prev/next)
Visual widget layout editor with grouped controls and semantic previews
Theme-aware, adjustable background plates keep labels and station information readable over wallpapers
Wallpaper from SD or an internet JPEG URL — a different one per screen, presets, scheduled refresh, save to SD, and adjustable dimming
Online wallpaper gallery — browse artwork matching your panel resolution and install it to the device without leaving the layout editor
Custom boot splash logo from SD
Photo slideshow from SD
Screensavers — clock hands, starfield, fireworks, plasma, Game of Life, blank, Dim, or Dashboard

Weather

Optional current temperature and conditions on the home screen
Weather Icons with day/night condition variants
Open-Meteo works without an API key
OpenWeatherMap available as an alternative provider
Coordinates and refresh interval configured from the web UI

Events & notifications

Birthdays, namedays, reminders
Recurring: daily / weekly / monthly / yearly
Phone calendar mirror — the Android app pushes your upcoming entries to the device, read-only
Fullscreen alert + buzzer melody
Playback schedule — start radio or SD music with an optional stop time
Voice notifications — play a recorded clip from SD at a set time
Programmable notification tunes

Connectivity

WiFi with captive-portal setup (AP mode), or type the password on the device itself
HTTP + WebSocket server on-device
Web UI served from SPIFFS — no cloud
mDNS — reachable at <hostname>.local, so the app and your browser find it without an IP
NTP with configurable timezone
MQTT — radio control + up to 6 widgets (toggle / slider / label) on a dedicated on-device screen
OTA firmware update from the web UI — dual-slot with rollback + firmware backup (16 MB builds)
Automatic updates — the device checks for a new release at boot and, after an on-screen confirmation, installs new firmware and refreshes the web UI by itself

Remote control

Android app — available on Google Play: playback, playlist, events, equalizer, layout editor and a podcast browser
Voice commands from the phone — English, Polish, Czech, German, French, Hungarian and Hindi
Hardware pilot over ESP-NOW — a battery-powered remote that never joins the WiFi, so a button press acts immediately instead of waiting for a connection; it can browse and play the SD card and read the radio's settings and diagnostics
MQTT commands from any automation system
One documented command set behind all of them — web UI, app, pilot and MQTT speak the same protocol

Setup & maintenance

Runtime pin map — every GPIO is configured on the device's own setup page and stored in flash, so one firmware binary drives any wiring, no rebuild
Diagnostics — memory and PSRAM use, chip temperature, firmware and web-UI versions, MQTT broker state; on screen and as a copyable report in the web UI
One-file backup — export settings, theme, events, MQTT config, layout and station list as a single JSON and restore it later; no SD card needed
SD file manager in the browser — browse, upload, rename, move and delete, with inline preview of display images
SPIFFS ⇄ SD copy tool for backing the device up to the card
Built-in text editor for the configuration and web files

Dashboard screensaver

Ambient display polling any JSON HTTP/HTTPS endpoint and rendering a single value
Configurable title, URL, JSON path, suffix, and poll interval
HTTPS out of the box via ESP-IDF certificate bundle
Ships with NBP USD/PLN rate; point it at weather, crypto, home automation, GitHub stats, …

Coming soon

Enclosure — 3D-printed case in design; runs on the custom AtlasCube PCB as well as bare dev boards
Web melody editor — in-browser tool for composing buzzer tunes
Infrared remote — a €1 receiver on one GPIO, taught the keys of any spare TV remote; the keys map onto the same action list the push-buttons already use
