A standalone ESP32-S3 project for the SenseCAP Indicator that displays real-time public transport departures (Bus & Train).

IMG_2391.mp4

This application fetches data from the Open Transport Data Swiss API and displays it on the device's screen using LVGL.

Features

• Bus Countdown: Shows minutes remaining until the next bus departures.
• Train Station Board: Displays upcoming train departures, platforms, and delays.
• Smart Refresh:
  • Updates every 5 minutes during the day (06:00 - 21:00).
  • Updates every 15 minutes at night to save power.
• Morning Schedule: Keeps the screen active during morning rush hour (06:15 - 07:15, Mon-Fri).
• WiFi Connectivity: Connects to your local network to fetch API data.

Configuration

Managing stations and stops

The list of bus/tram stops and train stations available in the app is defined in main/view/indicator_view.c:

• Bus/tram stops: edit the predefined_bus_stops[] array — add or change entries as {"Name", "ID"}.
• Train stations: edit the predefined_stations[] array the same way.

Find stop and station IDs via the API: http://transport.opendata.ch/v1/locations?query=CITY_NAME

Optionally, in main/model/transport_data.h (USER CONFIGURATION section) you can set default BUS_STOP_* / TRAIN_STATION_* and SELECTED_BUS_LINES (line filter, e.g. "1,2,4" or "*" for all).
