4.1 Techninės įrangos prijungimas

1. Power Off Raspberry Pi: Before connecting the camera, ensure your Raspberry Pi is completely powered off and disconnected from its power source.
2. Locate CSI Connector: Identify the CSI (Camera Serial Interface) connector on your Raspberry Pi board. This is typically a long, narrow slot.
3. Atidarykite jungtį: Gently pull up the plastic clip on the top edge of the CSI connector.
4. Insert FPC Cable: Carefully insert the FPC cable from the camera module into the CSI connector. Ensure the silver contacts on the cable are facing the correct direction (towards the HDMI port on most Raspberry Pi models). Use the appropriate FPC cable (15-pin or 22-pin) for your specific Raspberry Pi model.
5. Uždaryti jungtį: Push the plastic clip back down to secure the FPC cable in place.
6. Maitinimas: Reconnect the power to your Raspberry Pi.

4.2 Programinės įrangos konfigūracija

After connecting the hardware, you need to enable and configure the camera module in your Raspberry Pi's operating system.

1. Įjungti kameros sąsają:
   • Open a terminal on your Raspberry Pi.
   • Paleiskite komandą: sudo raspi-config
   • Eikite į Sąsajos parinktys -> Fotoaparatas ir įgalinkite jį.
   • Kai būsite paraginti, perkraukite „Raspberry Pi“.
2. Edit config.txt for OV5647: For optimal performance and detection, it is recommended to manually configure the config.txt file.
   • Atidarykite config.txt file using a text editor: sudo nano /boot/config.txt
   • Locate the line camera_auto_detect=1 ir pakeiskite jį į camera_auto_detect=0.
   • Pagal [all] section, add the line: dtoverlay=ov5647
   • Save the changes (Ctrl+O, then Enter for nano) and exit the editor (Ctrl+X).
   • Reboot your Raspberry Pi: sudo reboot

5. Naudojimo instrukcijos

Once the camera module is connected and configured, you can use various tools to capture images and videos.

5.1 Basic Usage with libcamera (Raspberry Pi OS Bookworm or newer)

• Take a still picture:libcamera-still -o test.jpg
• Įrašykite vaizdo įrašą:libcamera-vid -t 10000 -o test.h264 (records for 10 seconds)
• Preview kameros transliacija:libcamera-hello

5.2 Basic Usage with raspistill/raspivid (Legacy Raspberry Pi OS Bullseye or older)

• Take a still picture:raspistill -o image.jpg
• Įrašykite vaizdo įrašą:raspivid -o video.h264 -t 10000 (records for 10 seconds)
• Preview kameros transliacija:raspistill -t 0

For more advanced options and parameters, refer to the official Raspberry Pi camera documentation online. The camera supports a maximum still picture resolution of 2592 x 1944 and video resolution of 1080p at 30fps.

6. Priežiūra

• Objektyvo valymas: Use a soft, lint-free microfiber cloth specifically designed for optics to gently clean the lens. Avoid using abrasive materials or harsh chemicals.
• Saugykla: When not in use, store the camera module in an anti-static bag or a protective case to prevent dust accumulation and physical damage.
• Kabelių valdymas: Ensure the FPC cable is not sharply bent or crimped, as this can damage the internal conductors.
• Aplinkos sąlygos: Operate and store the camera within recommended temperature and humidity ranges to prolong its lifespan.

7. Problemų sprendimas

• Kamera neaptikta:
  • Ensure the FPC cable is correctly inserted into both the camera module and the Raspberry Pi's CSI connector, with the silver contacts facing the correct direction.
  • Verify that the camera interface is enabled in raspi-config ir kad config.txt modifications (as described in Section 4.2) have been applied and the Pi rebooted.
  • Check if the correct FPC cable (15-pin or 22-pin) is being used for your specific Raspberry Pi model.
  • Test the camera on another Raspberry Pi if available, or try a different FPC cable to rule out component failure.
• Dim or Poor Image Quality:
  • Ensure adequate lighting in the environment. This camera module performs best in well-lit conditions.
  • Clean the camera lens gently with a microfiber cloth.
  • The OV5647 module has a fixed-focus lens. Ensure your subject is within the optimal focus range (1m to infinity).
  • Update your Raspberry Pi OS to the latest version to ensure you have the most recent camera drivers and software.
• Lens Fell Off / Physical Damage:
  • Physical damage, such as a detached lens, typically indicates a manufacturing defect or improper handling. Contact Arducam support for assistance.
