6. سار سنڀال

Proper maintenance ensures the longevity and optimal performance of your camera module.

• لينس جي صفائي: Use a soft, lint-free microfiber cloth specifically designed for optical lenses to gently clean the camera lens. Avoid abrasive materials or harsh chemicals.
• سنڀالڻ: Handle the camera module by its edges to avoid touching the lens or the sensor area. Static electricity can damage electronic components.
• اسٽوريج: When not in use, store the camera in a clean, dry, and dust-free environment, preferably in its original packaging or an anti-static bag.
• ماحولياتي حالتون: Avoid exposing the camera to extreme temperatures, high humidity, or direct sunlight for extended periods.

7. مسئلا حل ڪرڻ

If you encounter issues with your Arducam IMX477 camera, consider the following troubleshooting steps:

• ڪئميرا نه ملي سگهيو:
  • Verify that the ribbon cable is correctly and securely connected to both the camera module and the Jetson board. An incorrect or loose connection is a common cause.
  • Ensure the correct kernel drivers are installed for your specific JetPack version. If your OS has been updated, drivers may need to be re-installed.
  • Confirm that your Jetson board is an official NVIDIA Developer Kit, as compatibility with third-party Jetson-like boards is not guaranteed.
• Focus Issues:
  • Check if the software application you are using supports motorized focus control.
  • Ensure the I2C communication for the focus motor is properly configured and not blocked by other processes.
• Image Quality Problems:
  • Clean the lens carefully as described in the Maintenance section.
  • Adjust exposure and white balance settings in your software to suit the lighting conditions.
• عام عدم استحڪام:
  • Ensure your Jetson board's power supply is adequate.
  • Consult Arducam's official support forums or documentation for the latest drivers and known issues.
