Guide to program STM3241G-EVAL board to communicate USB Camera over ethernet

Hi

I am very new to write a code for USB communication. I am looking for helpful link or resource in setting up USB based camera communication over ethernet.

I have the following questions

  1. What does the video camera acts like a USB host or Device?
  2. How can we initialize the vendor's camera to start transmitting the video frame?

There is a in build camera module on EVAL board but my project requirement is to use a see3_cam camera and transmit its video frames over ethernet.

Any help will be really appreciated.

Thanks

Perhaps there are some commercial USB stacks that have richer examples, and consultants with specific competencies?

If it is a USB Camera, and you're connecting it to the board, you'd need to be a USB HOST.

You'd need to understand the class and protocol it is using. Perhaps look at LINUX sources for supporting said camera, for expectations and initialization specifics.

I suspect you'll need to send USB request packets to the required endpoints on the camera/device.

Thanks @Community member​ for the helpful suggestion.

I will do the search for USB Host and library required for initialization of camera.

Thanks again

Thankyou @Piranha​  for the reply.

I will keep those instructions in mind for LWIP ethernet.
