Question 2 How to switch cameras with a 64MP QuadCamera?
Example:
# Set to single channel 0
i2cset -y 10 0x24 0x24 0x02
# Set to single channel 1
i2cset -y 10 0x24 0x24 0x12
# Set to single channel 2
i2cset -y 10 0x24 0x24 0x22
# Set to single channel 3
i2cset -y 10 0x24 0x24 0x32
# Set to double channel (single channel 0 and single channel 1)
i2cset -y 10 0x24 0x24 0x01
# Set to double channel (single channel 2 and single channel 3)
i2cset -y 10 0x24 0x24 0x11
# Set to four in one mode (Default)
i2cset -y 10 0x24 0x24 0x00
### Question 6 How to implement autofocus with libcamera_python on 64MP?(already fixed)
Ourl ibcamera_python library is not yet compatible with libcamera_dev 0.0.7,we will expedite the process of compatibility,you can try to install an stablize version of libcamera_dev.

Question 9 Can we extend the ribbon cable for the 64mp arducam 64mp or is there a limit?
Since the signal transmission speed is very fast, the signal will be attenuated during the transmission process. If the cable is too long, the final effect will be bad.
Question 12 64MP with RPI 4b, Rev 1.4, failed to allocate capture buffers
For 64MP cameras, there may be memory issues with the maximum resolution. We can’t reproduce it for now, but there are still some suggestions to help you with a simple troubleshooting:
cat /proc/meminfoCmaTotal should be around 500000kB
Try the command several times, because sometimes it doesn’t work well
Reduce the resolution to ensure that the camera is OK
