Can't detect the i2c to control the lens zoom and focus.

Bought a ptz camera and the camera works fine but I can’t detect the i2c to control the lens zoom and focus. When I plug in the 5v, gnd, Sdl and scl, should there be a led that light up when my pi is on?

Is the control board faulty?

Hello,

As normal, the circuit board is not so easy to damage. For the PTZ lens, the wiring is a little complicated. Generally, the i2c communication is abnormal due to the abnormal wiring.

So, firstly,please ensure your hardware connection is normal following our user guide.

Hello,

I use a Raspberry Pi 4B with a PTZ camera. When I run FocusExample.py, the menu with the camera preview appears but when I try to change the values of any function, the error “[Errno 121] Remote I/O error” appears.

I installed i2c-tools and python-smbus, i2c is enabled. I tried some solutions that I saw in forums but it does not work. The camera is detected when I do “i2cdetect -y 0”.

I checked my hardware connection and it is good. I do not understand what happens.

Thank you for your help.

Have you enable the i2c1 interface? Please run ls /dev/i2c* to check if the i2c1 exist.

I have /dev/i2c-0 and /dev/i2c-1.

But when I do “i2cdetect -y 1”, I only have “–”.

Hello, Remote I/O error means the program does find the i2c device. if the i2cdetect -y 1 does not find any addresses, it seems the hardware connection is abnormal. Please attach me your hardware connection diagram and I will help you check it in detail.

Hello, I did the hardware connection according to your user guide.

Please find my hardware connection.

Thank you.
