3. Тохиромжтой байдал

This camera module is primarily designed for use with Nvidia Jetson Developer Kits, including Jetson Orin NX and AGX Orin. It does not require hardware modifications for these platforms.

• Jetson Platform: Compatible with Jetson Developer Kits. It relies on kernel drivers for functionality.
• Жолоочийн шаардлага: Requires specific kernel drivers. Versions earlier than JetPack 4.3 (L4T 32.3.1) are not supported. Operating system updates that change the kernel version will necessitate re-installation of a matching driver.
• Raspberry Pi Compute Module: Can be used with Raspberry Pi Compute Modules (e.g., CM3, CM3+).
• Incompatible Platforms: Not compatible with standard Raspberry Pi models (e.g., Raspberry Pi 3/3B+/4). Compatibility with other third-party boards is not guaranteed.

4. Тохируулах заавар

Follow these steps to set up your Arducam IMX477 camera module with a compatible Jetson board:

1. Prepare the Jetson Board: Ensure your Nvidia Jetson Developer Kit is powered off and disconnected from any power source.
2. Connect the Ribbon Cable: Carefully connect one end of the provided ribbon cable to the CSI camera connector on the Arducam IMX477 module. Ensure the contacts are facing the correct direction.
3. Connect to Jetson: Connect the other end of the ribbon cable to the CSI camera input on your Jetson board. Ensure a secure connection.
4. Асаах: Reconnect power to your Jetson board and power it on.
5. Драйвер суурилуулах: Install the necessary kernel drivers for the Arducam IMX477 camera on your Jetson operating system. Refer to Arducam's official documentation or support resources for specific driver installation guides for your JetPack version.
6. Баталгаажуулалт: After driver installation, verify camera detection and functionality using appropriate software tools or example scripts provided by Arducam.

5. Ашиглалтын заавар

The Arducam IMX477 camera offers software-controlled focus, providing flexibility for various applications.

5.1 Focus Control

The motorized focus can be controlled in two primary ways:

• Manual Fine-tuning: Utilize keyboard arrow keys within compatible software applications to precisely adjust the focus.
• Автомат фокус: Implement autofocus functionality using provided OpenCV examples or custom scripts. This allows the camera to automatically adjust focus for optimal image clarity.

Refer to Arducam's software documentation and example code for detailed instructions on implementing and utilizing these focus control methods.

6. Засвар үйлчилгээ

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

• Линз цэвэрлэх: Use a soft, lint-free microfiber cloth specifically designed for optical lenses to gently clean the camera lens. Avoid abrasive materials or harsh chemicals.
• Харьцуулах: Handle the camera module by its edges to avoid touching the lens or the sensor area. Static electricity can damage electronic components.
• Хадгалах: Ашиглаагүй үедээ камерыг цэвэр, хуурай, тоосгүй орчинд, анхны савлагаанд нь эсвэл статик эсрэг уутанд нь хадгална уу.
• Байгаль орчны нөхцөл: Камерыг хэт өндөр температур, өндөр чийгшил эсвэл нарны шууд тусгалд удаан хугацаагаар өртүүлэхээс зайлсхий.

7. Алдаа засах

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

• Камер илрээгүй:
  • 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.
• Анхаарал төвлөрүүлэх асуудлууд:
  • 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.
• Зургийн чанарын асуудлууд:
  • Clean the lens carefully as described in the Maintenance section.
  • Adjust exposure and white balance settings in your software to suit the lighting conditions.
• Ерөнхий тогтворгүй байдал:
  • Ensure your Jetson board's power supply is adequate.
  • Consult Arducam's official support forums or documentation for the latest drivers and known issues.
