I just installed B0444 2MP IMX462 camera on Raspberry Pi 3B+ with the following OS version:
pi@raspberrypi:~ $ uname -a
Linux raspberrypi 6.1.21-v7+ #1642 SMP Mon Apr 3 17:20:52 BST 2023 armv7l GNU/Linux
pi@raspberrypi:~ $ cat /etc/os-release
PRETTY_NAME=“Raspbian GNU/Linux 11 (bullseye)”
NAME=“Raspbian GNU/Linux”
VERSION_ID=“11”
VERSION=“11 (bullseye)”
VERSION_CODENAME=bullseye
The camera is working fine except the focus feature is not working in PiCamera2. I use the code example from Pivariety-Camera-PiCamera2-User-Guide:
import time
from picamera2 import Picamera2, Preview
picam2 = Picamera2()
picam2.start_preview(Preview.QTGL)
preview_config = picam2.create_preview_configuration()
picam2.configure(preview_config)
picam2.start()
time.sleep(1)
picam2.set_controls({"AfTrigger": 0})
time.sleep(5)
Then, I got the following error. Please advise how to use the manual focus for this camera?
