Hi all,

Im working on jetson xavier nx with two imx219 arducam cameras, both with motorized focus.

im tring to adjust the focus on each camera manually with the os command ( os.system("i2cset -y 2 0x0c 21 60) - for example).

its seems that every time its changes the focus on a different camera without me changing the addresses or the command (except the focus value).
why is that ? and how can i control it diffrently? or how can i check what is each camera address?

thanks alot!

I think the focus slave address is the same it the module is the same, but the bus number should be different. You may check the bus number by v4l2-ctl --list-devices, like below 30 is the bus number.

nvidia@nvidia-desktop:~$ v4l2-ctl --list-devices
