Tool/software: Linux

Hi,

I am using AM4379 IDK. I am trying to interface CMUcam5 PIXY camera using I2C.

I am not able to identify registers to be initialized. I am assuming AM437x IDK as a master

how to get details about it.

Thank You

Hi Vishnu,

I can give you only a general advice because I'm not familiar with the CMUcam5 PIXY camera.
If you are using some modern Linux kernel you must add a camera I2C node in the device tree. You can search in the net for an example but I also suggest you some examples:

elixir.bootlin.com/.../ad5820.txt

Hi Tsvetolin Shulev
No need to worry about CMUcam5 PIXY camera. It is already configured as I2C slave. And I have to write code to access data from it using read system call,because I am using Linux Processor SDK.
Is this SDK is coming with I2C library?
Can you help me to start interacting with I2C.
Regards
Vishnu

Vishnu,

Linux kernel documentation gives you an useful guide about i2c at:
www.kernel.org/.../dev-interface
Also take a look at:
