Features

• 📡 Automatic WiFi connection via WiFiManager
• 🌐 Web interface for device management
• 🔄 Automatic schedule updates from server
• 📱 Captive portal for initial WiFi setup
• 🖥️ Horizontal screen orientation 240x135

Requirements

Arduino Libraries:

• Adafruit GFX Library
• Adafruit ST7789 Library
• WiFiManager (for ESP32)
• ArduinoJson
• HTTPClient (built-in for ESP32)

Hardware:

• ESP32
• ST7789 TFT display (240x135 or 135x240)
• Connecting wires

Display Connection

ESP32    ->  ST7789
D23      ->  MOSI
D18      ->  SCLK
D15      ->  CS
D2       ->  DC
D4       ->  RST
D32      ->  BLK (optional)

Setup

1. Install required libraries via Arduino IDE Library Manager
2. Open esp32-bus-schedule.ino in Arduino IDE
3. In config.h file, specify your API server URL:

   #define SCHEDULE_SERVER_URL "https://your-api-server.com/api/schedule"

4. Upload code to ESP32

Initial WiFi Setup

1. On first boot, device will create access point BusSchedule_Setup
2. Connect to this network from phone/computer
3. Open browser and navigate to 192.168.4.1
4. Select your WiFi network and enter password
5. Device will automatically connect to network

Web Interface

After connecting to WiFi, open device IP address in browser (displayed on screen).

Available pages:

• / - Main page with information
• /config - WiFi configuration
• /reset - Reset WiFi settings

API Format

Server should return JSON in the following format:

{
  "buses": [
    {"number": "123", "time": "10:30"},
    {"number": "456", "time": "10:45"}
  ]
}
