No response from Arducam, but posting this in case anyone else needs to know. On RaspberryPi 4B, if you cannot get your 12MP*2 Synchronized Stereo Camera Bundle working, you need to use i2cset. A couple of minutes of trial and error today got me to the answer I needed. i2cset -y 0x24 0x24 0x00 puts the camera hat in stereo mode with the feed from both cameras passed to the operating system as if from a single camera.
Hi @lloydtravissmith,
I am wondering if everything is fine with you working simultaneously with multiple cameras now. For me, cameras are detected but the preview window is like this:
I used this POST and installed low speed kernel, and now I have this error:

Anyone has any ideas what is the issue?
Hi,
Can you post the product link here?
@Dion the link brings me back here!
This link is my first issue. Then after installing the low-speed package I got new errors as mentioned above and no preview is available.
Could you please let me know what I need to do for solving the issue?
Thanks.
Hi,
My bad! It should be the link below:
Thanks @Dion Dion.
It works well as shown below.
Now, I have another issue and am not sure what is causing it. I wanted to capture pictures with different exposures. Here is the code I use:
import picamera
from time import sleep
from fractions import Fraction
with picamera.PiCamera() as camera:
camera.framerate = Fraction(1, 2)
camera.rotation = 0
camera.iso = 100
camera.exposure_mode = 'auto'
camera.awb_mode = 'off'
camera.awb_gains = (2.9,1.7)
# detect camera version so that it resolution can be set
if (camera.revision).upper() == "IMX519":
try:
camera.resolution = (4056,3040)
except:
print("Review readme for change in memory split to get full support for Camera v2")
print("Resolution kept at 2592x1944")
camera.resolution = (4056,3040)
else:
camera.resolution = (4056,3040)
exposures = [250000, 125000, 66667,33333, 16667, 8000, 4000,
2000]
i = 1
for exp in exposures:
camera.shutter_speed = exp
camera.capture('ldr_{:02d}.jpg'.format(i))
i += 1
but I got this error:
python exposurebracket.py

Seems the code works with legacy camera which is not compatible with quad camera. Any idea how to capture different exposure pictures with libcamera and quad camera without any issue?
Thanks
Hi, Dion. I have same problem.
I have:
- 4 Arducam 5MP OV5647 1080p Mini Camera Module for Raspberry Pi 4
- Raspberry Pi 4
- Raspberry Pi Multi CameraAdapter Module V2.2
I followed steps from RaspberryPi/Multi_Camera_Adapter/Multi_Adapter_Board_4Channel at master · ArduCAM/RaspberryPi · GitHub
and alsow i modified the Config.txt with
dtoverlay=camera-mux-4port,cam0-,cam1-,cam2-,cam3-
On “test” step all 4 cameras displayed one by one.
terminal output
sudo ./init_camera.sh
