Egiaztatu elementu guztiak zure paketean daudela:

• 1 x Arducam 12MP IMX708 Camera Module 3
• 1 x 66° HFOV Autofocus Lens (integrated)
• Raspberry Pi compatible FFC cables (various lengths/types for different Pi models)

3. Konfigurazioa

3.1 Hardware konexioa

Carefully connect the camera module to your Raspberry Pi board using the appropriate Flexible Flat Cable (FFC). Ensure correct orientation to prevent damage.

Figure 2: FFC cable connection instructions for various Raspberry Pi models.

• Raspberry Pi 5rako: The metal contacts of the FFC cable should face the Ethernet port.
• For Raspberry Pi 4B/3B: The metal contacts of the FFC cable should face the HDMI port.
• For Raspberry Pi Zero W/2 W: The metal contacts of the FFC cable should face DOWN (towards the main board). Note that a thinner FFC cable is required for Pi Zero models.

3.2 Software konfigurazioa

The Arducam Camera Module 3 requires specific software configuration on your Raspberry Pi. This camera module is designed for the new camera stack (libcamera/Picamera2) and is not compatible with the legacy camera stack (raspistill/raspivid).

1. Install Raspberry Pi OS: Ensure your Raspberry Pi is running a recent version of Raspberry Pi OS (e.g., Bullseye OS or newer) that supports the new camera stack.
2. Update System: Open a terminal and run the following commands to update your system:

   sudo apt update && sudo apt upgrade

3. Install libcamera-apps: Install the necessary camera applications:

   sudo apt install libcamera-apps

   For headless setups, consider `sudo apt install rpicam-apps-lite`.
4. Configure `config.txt`: Edit the boot configuration file:

   sudo nano /boot/firmware/config.txt

   Locate or add the following lines:

   camera_auto_detect=0
   dtoverlay=imx708

   Save and exit the editor.
5. Enable I2C: If not already enabled, enable I2C via `raspi-config`:

   sudo raspi-config

   Nabigatu Interfaze aukerak > I2C eta gaitu ezazu.
6. Berrabiarazi: Reboot your Raspberry Pi for changes to take effect:

   sudo reboot

4. Funtzionamendu-argibideak

After successful setup, you can operate the camera using `libcamera` commands or the Picamera2 library.

4.1 Basic Commands (libcamera)

• List Cameras: Verify the camera is detected:

  rpicam-hello --list-cameras

  You should see output similar to: `0 : imx708 [4608x2592 10-bit RGGB]`.
• Capture Still Image: Capture a JPEG image:

  rpicam-jpeg -o test.jpg

• Grabatu bideoa: Record an H.264 video:

  rpicam-vid -t 10000 -o video.h264

  (Records for 10 seconds)

4.2 Autofocus and HDR

The IMX708 sensor supports autofocus (PDAF and CDAF) and HDR. These features are typically managed automatically by the libcamera stack. For advanced control, refer to the official libcamera and Picamera2 documentation for specific parameters and settings.

5. Mantentzea

The Arducam Camera Module 3 is a delicate electronic component. Follow these guidelines for proper maintenance:

• Manipulazioa: Always handle the camera module by its edges to avoid touching the lens or sensor.
• Garbiketa: Use a soft, lint-free cloth or a specialized lens cleaning pen to gently clean the lens if necessary. Avoid abrasive materials or harsh chemicals.
• Biltegiratzea: Store the camera in a dry, dust-free environment when not in use.
• Kableen zainketa: Ensure FFC cables are not bent sharply or stressed, as this can damage the conductors.

6. Arazoak

If you encounter issues with your Arducam Camera Module 3, consider the following:

• "No Cameras Available" Error:
  • Verify the FFC cable is correctly inserted at both the camera module and the Raspberry Pi. The metal contacts must be fully engaged and facing the correct direction as described in Section 3.1. Try flipping the cable at each end, one at a time, and rebooting.
  • Ensure `camera_auto_detect=0` and `dtoverlay=imx708` are correctly set in `/boot/firmware/config.txt`.
  • Confirm I2C is enabled via `raspi-config`.
  • Ensure your Raspberry Pi OS is updated and `libcamera-apps` are installed.
• `dmaHeap allocation failure` Error: This error, often seen on older Pi models (e.g., Pi 4 running Bookworm), indicates insufficient memory for camera buffers. While increasing CMA (Contiguous Memory Allocator) might help, it's not always a guaranteed fix. Consider reducing resolution or frame rate, or using a newer Raspberry Pi model if possible.
• Poor Image Quality/Focus Issues:
  • Kendu lentearen babes-film oro.
  • Ziurtatu zure ingurunean argiztapen egokia dagoela.
  • For specific autofocus control, consult the libcamera/Picamera2 documentation for manual focus options.
• Compatibility with Pi Zero: While compatible, ensure you are using the correct, thinner FFC cable designed for the Pi Zero's smaller camera connector.
