    Accessing UVC controls

      Hi,

         

      I am building an application with CX3 interfacing Omnivision camera. I went through e-con systems firmware to see how they are enabling various controls, like brightness, exposure, sharpness etc.

         

      I see that they use wValue and wIndex to figure out what type of command was issued from the host.

         

      From what I understand, wIndex = 0x100 corresponds to Camera Terminal commands and 0x200 to Processing Unit Terminal commands. But I dont see a relation between wValue and the controls.

         

      Is there a document or any resource where I can see how the controls are tied to wValue and wIndex?

         

       

         

      Thanks.
