Why i runing sample but has error Failed to set I2C address 😱

I'm experiencing the same thing. Any solutions?

[asnewman]

Looks like the most recent commit broke the code. I checked out 4d271ade72e1d9b0af889cd6351dafd460b10d00 and it worked.

[ArduCAM]

@asnewman For the latest system version, the i2c adapter is i2c10 instead of i2c0. We have updated our lib to compatible with the latest system. Please run uname -a command to check your kernel verson and run **ls /dev/i2c*** command to check if it exist i2c10 adapter.

[asnewman]

@ArduCAM Thanks for the tip. When I ran the commands I get:

Linux raspberrypi 4.19.118-v7+ #1311 SMP Mon Apr 27 14:21:24 BST 2020 armv7l GNU/Linux

and

/dev/i2c-0  /dev/i2c-1

Do I need to run some sort of update command?

[npaibrooklyn]

Any update on this? I am facing the same issue

[bigdognj]

Just received my pi autofocus camera, installed everything as directed and am getting the same error as above when running the first Python demo. There are no I2C drivers in my /dev/ directory. What to do?

I am also facing the same issue. Im getting error failed to set i2c address when I try to run Motorized_Focus_Camera_Preview.py and try to adjust the focus.
