Overview
In this application, FX3 interfaces to a parallel image sensor over the General Programmable Inter-
face (GPIF II). The FX3 firmware supports the USB Video Class (UVC) and communicates with a
USB 3.0 or USB 2.0 host. An application such as Debut Video Capture is used for viewing video on
the PC. This application communicates directly with the UVC driver on the PC.
The control commands to the image sensor are communicated by FX3 over the I2C interface.
The details of the GPIFII descriptor and the firmware implementation can be found in the application
