3.2 Pradiniai nustatymo žingsniai
- Paruoškite „Micro SD“ kortelę: Download a compatible operating system image (e.g., Raspberry Pi OS) from the official Raspberry Pi website. Use an imaging tool (like Raspberry Pi Imager) to write the OS image to your Class 10 Micro SD card.
- Įdėkite Micro SD kortelę: Gently insert the prepared Micro SD card into the card slot on the underside of the Raspberry Pi board.
- Prijunkite išorinius įrenginius:
- Connect your HDMI display to the HDMI port on the Raspberry Pi.
- Prijunkite USB klaviatūrą ir pelę prie galimų USB prievadų.
- (Optional) Connect an Ethernet cable to the Ethernet port for wired network access.
- Taikyti galią: Connect the 2.5A Micro USB power supply to the Micro USB power port on the Raspberry Pi. The device will automatically power on and begin booting.
- Pirmasis paleidimas: Follow the on-screen instructions to complete the initial setup of the operating system, including setting up Wi-Fi, language, and user accounts.
4. Operacinis
4.1 Pagrindinės operacijos
Once the operating system is installed and configured, your Raspberry Pi is ready for use. You can interact with it via the connected keyboard, mouse, and display, similar to a traditional desktop computer. The Raspberry Pi OS provides a graphical user interface (GUI) for ease of use.
4.2 Software Installation and Updates
Software can be installed via the graphical "Add/Remove Software" utility or through the command line using `apt` commands (e.g., `sudo apt update`, `sudo apt install [package_name]`). Regular updates are recommended to ensure system stability and security.
4.3 GPIO Usage
The 40-pin GPIO header allows for advanced projects involving physical computing. You can connect various sensors, actuators, and other electronic components to control them programmatically using languages like Python.
Refer to the official Raspberry Pi documentation for detailed guides on GPIO programming and hardware interfacing.
5. Priežiūra
- Programinės įrangos atnaujinimai: Regularly update your operating system and installed software packages to receive the latest features, bug fixes, and security patches. This can typically be done via the terminal using `sudo apt update` followed by `sudo apt upgrade`.
- Galios valdymas: Always use a stable and sufficient power supply (5.1V / 2.5A) to prevent unexpected shutdowns or data corruption. Avoid disconnecting power without properly shutting down the operating system first.
- SD kortelės priežiūra: Micro SD cards can wear out over time. Regularly back up your data and consider using high-quality, durable cards. Avoid frequent power cuts to minimize the risk of SD card corruption.
- Fizinė aplinka: Keep the Raspberry Pi in a cool, dry, and well-ventilated area. Avoid exposing it to extreme temperatures, humidity, or dust. Consider using a protective case.
6. Problemų sprendimas
- Nėra maitinimo / įkrovos:
- Ensure the power supply is correctly connected and meets the 5.1V / 2.5A specification.
- Check the Micro SD card for proper insertion and ensure it has a valid operating system image.
- Look for the red power LED (PWR) to be steadily lit and the green activity LED (ACT) to flash during boot.
- Rodymo problemos:
- Verify the HDMI cable is securely connected to both the Raspberry Pi and the display.
- Ensure your display is set to the correct input source.
- Tinklo ryšio problemos:
- For wired Ethernet, check the cable connection and router status.
- For Wi-Fi, ensure the correct network name (SSID) and password are entered in the OS settings.
- Restart your router and the Raspberry Pi.
- Periferinis įrenginys nereaguoja:
- Pabandykite prijungti USB įrenginius prie skirtingų USB prievadų.
- For Bluetooth devices, ensure they are in pairing mode and correctly configured in the OS.
