2. Donant poder a la junta
The board can be powered via the USB Type-C port or a 3.7V LiPo battery.
- Potència USB: Connect a USB Type-C cable from your computer or a 5V USB power adapter to the board's USB port.
- Potència de la bateria: Connect a 3.7V LiPo battery to the JST 2-pin battery connector. Ensure the battery switch is in the 'ON' position to power the board from the battery.
3. Initial Firmware Upload (Optional)
For initial setup or custom firmware, you may need to upload firmware. Refer to the official LILYGO GitHub repository for detailed instructions and exampel codi:
github.com/Xinyuan-LilyGO/Lilygo-LoRa-Epaper-series
Typically, you will need to press and hold the Arrencada botó i, a continuació, premeu breument Restableix button, and release the Arrencada button to enter programming mode. Use a suitable ESP32-S3 development environment (e.g., Arduino IDE with ESP32 board support, PlatformIO) to upload your code.
Operating the Board
Funcionament bàsic
Once powered and programmed, the LILYGO T3S3 board will execute the loaded firmware. The 0.96-inch OLED display can be used to show real-time data, status, or other information as programmed.
Using the OLED Display
The OLED display is connected via I2C. The SDA pin is IO18 and the SCL pin is IO17. Libraries such as Adafruit_SSD1306 are commonly used for programming the display.
Comunicació LoRa
The SX1276 LoRa transceiver operates at 915MHz. Ensure your LoRa application adheres to local regulations for frequency usage and transmission power. Example code for LoRa communication can be found in the provided GitHub repository.
Ús de la targeta TF
The onboard TF card slot allows for data logging or storing configuration files. Standard SD card libraries can be used to interface with the TF card.
Manteniment
- Mantenir sec: Protect the board from moisture and extreme temperatures.
- Manejar amb cura: Avoid static discharge when handling the board. Use anti-static precautions.
- Neteja: Keep the board free from dust and debris. Use a soft, dry brush or compressed air for cleaning.
- Actualitzacions de firmware: Regularly check the official GitHub repository for firmware updates and improvements.
- Cura de la bateria: If using a LiPo battery, follow standard LiPo battery safety guidelines for charging and storage. Do not overcharge or deep discharge.
Resolució de problemes
- La placa no s'encén:
- Ensure USB cable is properly connected and providing power.
- If using battery, check battery charge level and ensure the battery switch is in the 'ON' position.
- Firmware upload fails:
- Verify correct COM port is selected in your IDE.
- Ensure you are holding the Arrencada button while pressing and releasing Restableix, then releasing Arrencada per entrar al mode de programació.
- Check USB cable for data transfer capability (some cables are charge-only).
- Install necessary USB drivers for the ESP32-S3.
- OLED display not working:
- Verify I2C connections (SDA to IO18, SCL to IO17) in your code.
- Ensure the correct display library (e.g., Adafruit_SSD1306) is installed and initialized correctly.
- LoRa communication issues:
- Ensure the antenna is securely connected.
- Verify that both transmitting and receiving devices are configured for the correct frequency (915MHz) and LoRa parameters (spreading factor, bandwidth, coding rate).
- Check for local interference or obstructions.
