Currently developing a UVC Camera system using Omnivison Camerachips(ov7725) with cyusbkit-003. The API CyU3PI2cReceiveBytes() returns Timeout error code. I don't know why. SCCB?
It could be an SCCB incompatibility (although most SCCB slaves also conform to the I2C protocol). Can you take a logic analyser/oscilloscope capture and post it here?
