4. Instrucións de configuración

Follow these steps to assemble and connect your camera extension kit to a Raspberry Pi.

4.1 Hardware Assembly

1. Attach IMX219 Camera Module to Tx Board: Carefully connect the 8MP IMX219 camera module to the Arducam GMSL2 camera Tx (Serializer) board. Ensure the ribbon cable is inserted correctly and the latch is secured.
2. Connect Fakra Coaxial Cable: Connect one end of the 1m Fakra Z coaxial cable to the Tx board and the other end to the Rx (Deserializer) board. Ensure the connectors click into place securely.
3. Mount Rx Board to Raspberry Pi: Attach the Arducam GMSL2 Rx board to your Raspberry Pi (compatible with Pi 4B and Pi 5). Use the provided stand-offs and screws to secure the board to the Raspberry Pi's mounting holes.
4. Connect FPC Cable: Connect the 40mm 22-22pin FPC cable from the Rx board to the CSI-2 camera port on your Raspberry Pi. Note that the white cable is typically for Pi 5 and the bronze/orange cable for Pi 4. Ensure the cable is inserted with the contacts facing the correct direction and the connector latch is closed.

4.2 Configuración do software

After hardware assembly, configure your Raspberry Pi OS to recognize and utilize the camera. This typically involves enabling the camera interface and using libcamera ferramentas.

1. Update Raspberry Pi OS: Ensure your Raspberry Pi OS is up to date by running:

   sudo apt update && sudo apt full-upgrade -y

2. Activar a interface da cámara: Use the Raspberry Pi configuration tool:

   sudo raspi-config

   Navega ata Opcións de interface > Cámara and enable it. Reboot your Raspberry Pi if prompted.
3. Verify Camera Detection: After reboot, you can check if the camera is detected using libcamera-still:

   libcamera-still --list-cameras

   You should see your IMX219 camera listed.

5. Instrucións de funcionamento

This section covers basic commands for operating your Arducam GMSL2 camera with Raspberry Pi.

5.1 Capturing Still Images

To capture a still image, use the libcamera-still comando:

libcamera-still -o image.jpg

This command will capture an image and save it as image.jpg in your current directory.

For a preview window and autofocus, you can use:

libcamera-still -t 0 --autofocus --keypress

This command will open a preview window, enable autofocus, and wait for a key press to capture an image. Press 'q' to quit the preview.

5.2 Gravación de vídeo

To record video, use the libcamera-vid comando:

libcamera-vid -t 10000 -o video.h264

This command will record video for 10 seconds (10000 milliseconds) and save it as video.h264.

5.3 En directo Preview

For a continuous live preview without saving, use libcamera-still with a long timeout and no output file:

libcamera-still -t 0

Press 'q' to quit the preview.

6. Mantemento

• Keep the camera lens clean using a soft, lint-free cloth. Avoid abrasive materials.
• Garde o kit nun ambiente seco e libre de po cando non o use.
• Regularly check cable connections for looseness or damage.
• Ensure proper ventilation for the Raspberry Pi and camera boards during operation to prevent overheating.

7 Solución de problemas

• Cámara non detectada:
  • Verify all ribbon and coaxial cable connections are secure and correctly oriented.
  • Ensure the camera interface is enabled in raspi-config.
  • Check if the Raspberry Pi OS is updated to the latest version.
  • Confirm the FPC cable type matches your Raspberry Pi model (white for Pi 5, bronze for Pi 4).
• Poor Image Quality / No Signal:
  • Inspect the Fakra coaxial cable for kinks or damage.
  • Asegúrate de que a lente da cámara estea limpa e libre de obstrucións.
  • Check the power supply to the Raspberry Pi; insufficient power can affect camera performance.
• Problemas de enfoque automático:
  • Ensure sufficient lighting in the environment.
  • Try manually focusing if the libcamera command supports it, or restart the application.
