INTRODUCTION
- About ArducamArducam has been a professional designer and manufacturer of SPI, MIPI, DVP, and USB cameras since 2012. We also offer customized turnkey design and manufacturing solution services for customers who want their products to be unique.
- About Pivariety CameraArducam Pivariety is a Raspberry Pi camera solution to take the advantage of using its hardware ISP functions. Using Arducam Pivariety camera modules, users can get better performance and a wider variety of camera, lens options. For a long time, Raspberry Pi users are limited to use the closed-source official supported camera driver and camera modules (V1/V2/HQ). Now Arducam made it possible to provide well-tuned ISP for Pivariety camera modules with Auto Exposure, Auto White Balance, Auto Gain Control, Lens Shading Correction, etc. This series of cameras use the libcamera framework, they can’t be supported by Raspistill, and the way to access the camera is libcamera SDK(for C++)/libcamera-still/ libcamera-vid/Gstreamer.

SOFTWARE
- Driver Installationwget -O install_pivariety_pkgs.shhttps://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.shchmod +x install_pivariety_pkgs.sh./install_pivariety_pkgs.sh -p kernel_driverpress y to rebootNOTE: The kernel driver installation only supported by the latest version 5.10. For other kernel versions, please go to our Doc page:https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-install-kernel-driver-for-pivarietycamera/#2-how-to-build-raspberry-pi-kernel-driverfor-arducam-pivariety-cameraYou can also visit this doc page to refer to the hardware connection: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/21mp-imx230pivariety-motorized-focus-camera-module/
- Test the Driver and CameraAfter you’ve finished the hardware assembly and driver installation, you can test whether the camera is detected and working.• View the Status of Driver and Cameradmesg | grep arducamIt will display arducam-pivariety if driver installed successfully and firmware version if the camera can be detected.The display should be probe failed if the camera can’t be detected, you might have to check the ribbon connection, then reboot the Raspberry Pi.• View the Video NodeThe Pivariety camera modules are emulated as the standard video device under /dev/video* node, so you can use the ls command for listing the contents in the /dev folder.ls /dev/video* -lSince the camera module is V4L2 compliant, you can use the V4l2 controls to list the supported color space, resolutions, and frame rates.v4l2-ctl –list-formats-extNOTE: Although V4L2 interface is supported, only RAW format images can be obtained, without ISP support.
- Official Libcamera App Installation./install_pivariety_pkgs.sh -p libcamera_dev./install_pivariety_pkgs.sh -p libcamera_apps
- Capture Image and Record Video• Capture imageFor example, preview for 5s and save the image named test.jpg libcamera-still -t 5000 -o test.jpg• Record videoFor example, record a H.264 10s video with the frame size 1920W × 1080H libcamera-vid -t 10000 –width 1920 –height 1080 -o test.h264NOTE: H.264 format only supports 1920×1080 and below resolution.• Plugin gstreamer installationInstall gstreamersudo apt updatesudo apt install -y gstreamer1.0-toolsPreviewgst-launch-1.0 libcamerasrc ! ‘video/xraw,width=1920,height=1080’ ! videoconvert ! autovideosink
- Control the Focusing Manually• Control via v4l2-ctlv4l2-ctl -c focus_absolute=300• Control via scriptgit clone https://github.com/ArduCAM/ArducamPivariety-V4L2-Driver.gitcd Arducam-Pivariety-V4L2-Driver/focuspython3 FocuserExample.pyNow you can use the up and down on the keyboard to control the focus position
- Automatically Control the Focusing• Focus oncelibcamera-still -t 0 –autofocuslibcamera-vid -t 0 –autofocus• Enable autofocus using Flibcamera-still -t 0 –keypresspress f to trigger autofocus
report this adNOTE: Note: Please install the Arducam latest version of libcamera-dev and libcamera-apps, and update the firmware of Pivariety(contacting Arducam: [email protected]) if the camera can not autofocus.
