Kit contains:

• L084 lens with controller kit
• IMX477 camera module
• Raspberry Pi CM3 and IO boards
• Mounting brackets to keep all the parts tidy
• HDMI and USB cables

The lens demonstration kit is set for rapid evaluation and additionally requires:

Raspberry Pi setup

Already done, if you wish to run a demo, skip to the next chapter

SD card preparation:

• Use Raspberry Pi Imager to flash the SD card with Raspberry Pi Buster OS (Do not use Bullseye OS)
• Within Raspberry, Pi Imager enable SSH, Wifi
• Raspberry pi user/pass: pi/test

 

OS preparation:

• Optional: use a USB hub to connect the wireless dongle, keyboard, and mouse to Raspberry Pi
• Connect display over an HDMI cable
• Make sure Raspberry pi is connected to the network
• Open terminal (SSH or on Desktop) and update OS: sudo apt update sudo apt full-upgrade
• And reboot sudo reboot
• Power off Raspberry Pi
• Wire control signals on the IO board like in the diagram below:

 

• Connect to the Raspberry Pi terminal
• Run command sudo raspi-config
• Select menu Interface options / Camera and select ENABLE
• Do not restart when asked, exit configuration program
• Update blob configuration sudo wget https://datasheets.raspberrypi.com/cmio/dt-blob-dualcam.bin -O /boot/dt-blob.bin
• Now reboot with a command sudo reboot
• After Raspberry has rebooted, connect to the console and check if the camera is detected vcgencmd get_camera
• In order to test the video, run command raspivid -f -k -awb greyworld -mm average -t 0
• For more convenient behavior, add this command to /etc/rc.local - camera will start video on HDMI port right after reboot

Demo

Connectivity

Connect cables between the lens kit and a computer:

• USB-micro cable #1 - Raspberry Pi power (optionally can be connected to the included wall charger)
• USB-micro cable #2 - lens controller
• HDMI - live camera view

 

Software

Software is maintained on GitHub. Check the releases section https://github.com/Kurokesu/SCE2-SDK/releases for latest the compiled version.

Workflow

1. Connect all the cables (HDMI and both USB) to a computer.
2. After Raspberry Pi boots, it will start displaying a live picture from the camera
3. Download, unzip and start demo software L084_SCE2_tester.exe
4. Select com port and press connect, the lens should be identified, and controls enabled
5. Click Seek ref for each axis (if the button is not enabled, try moving the axis manually, this is a temporary issue that will be fixed in future releases)
6. Click each preset Go button to move the lens to the a different zoom/focus position.
7. Move each axis manually < and > buttons to change focus and zoom.
