ArduCam B0333 2MP IMX462 Pivariety Low Light Camera Module for Raspberry Pi User Guide

INTRODUCTION

• About ArduCam
  ArduCam 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 Camera
  ArduCam 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-turned 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 Rasp still, and the way to access the camera is libcamera SDK(for C++)/libcamera-still/ libcamera-vid/Streamer.

SPECIFICATION

SOFTWARE

1. Driver Installation

wget -O install_pivariety_pkgs.sh https://github.com/ ArduCam/Arducam- Pivariety- V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh chimed +x install_pivariety_pkgs.sh ./install_pivariety_pkgs.sh -p kernel driver press y to reboot

NOTE: 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-camera

You can also visit this doc page to refer to the hardware connection: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/2mp- imx462pivariety-low-light-camera-module/

2. Test the Driver and Camera
After 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 Camera

dmesg | grep ArduCam
It 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 Node

The 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 –
l Since 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-ext.

NOTE: Although V4L2 interface is supported, only RAW format images can be obtained, without ISP support.

3. Official Libcamera App Installation
./install_pivariety_pkgs.sh -p libcamera_dev
./install_pivariety_pkgs.sh -p libcamera_apps

4. Capture Image and Record Video

• Capture image

For example, preview for 5s and save the image named test.jpg
libcamera-still -t 5000 -o test.jpg

• Record video

For example, record a H.264 10s video with the frame size 1920W × 1080H

libcamera-vid -t 10000 –width 1920 –height 1080 -o test.h264

NOTE: H.264 format only supports 1920×1080 and below resolution.

• Plugin streamer installation

Install streamer sudor apt update

sudor apt install -y gstreamer1.0-tools

Preview
gst-launch-1.0 libcamerasrc ! ‘video/xraw,width=1920,height=1080’ ! videoconvert ! autovideosink

TROUBLESHOOT

1. Cannot Allocate Memory
[3:45:35.833744413] [6019] INFO RPI raspberrypi.cpp:611 Sensor: / base/soc/i2c0mux/i2c@1/arducam@0c ­ Selected mode: 5344×4012-pRAA [3:45:35.948442507] [6019] ERROR V4L2 v4l2_videodevice.cpp:1126 /dev/video14[17:cap]: Unable to request 4 buffers: Cannot allocate memory [3:45:35.948551358] [6019] ERROR RPI raspberrypi.cpp:808 Failed to allocate buffers ERROR: failed to start camera

Edit /boot/cmdline.txt and add cma=400M at the end More details: https://lists.libcamera.org/pipermail/libcamera- devel/2020-December/015838.html

2. The Image Displays Color Dots
Add code –denoise cdn_off at the end of command ./libcamera-still -t 5000 -o test.jpg –denoise cdn_off More details: https://github.com/raspberrypi/libcameraapps/issues/19

3. Failed to Install the Driver
Please check the kernel version, we only provide the driver for the latest official kernel version image when this Pivariety camera released.

Note: If you want to compile the kernel driver by yourself, please refer to Doc page: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety /how-to-installkernel-driver-for-pivariety-camera/

4. Failed to import fd 18
terminate called after throwing an instance of ‘std : : runtime_error’ what( ): failed to import fd 18 Aborted

If you find the same error, you may make the wrong selection about the graphics driver. Please follow ArduCam Doc page to select the correct graphics driver.

5. Switch to the native camera (raspistill etc.)
Edit the file of /boot/config.txt, make dtoverlay=ArduCam change to # dtoverlay=ArduCam After the modification is completed, you need to reboot the Raspberry Pi. soda reboot
