Hi,

 

I have a UVC stream design based on AN75779, now I want to give commands (ex. Auto exposure, white balance etc.) to FX3 board with the same cable which is used for video stream. 

 

I need an idea for how this can be done. Any application note or reference document would be helpful.

 

Thanks & Regards, 

Akash

Hi,

Kindly elaborate on what are these commands and do you wish to send them from FX3?

Hi @MallikaK_22 ,

 

My video pipeline is     Image sensor -> FPGA -> FX3 -> USB host.

I want to connect my USB host with FX3 with only one USB cable which is now being used for video stream. I want to send serial commands (UART/I2C) from my usb host to fpga via FX3 while video streaming but only with the same USB port.

Main purpose is to detect FX3 as a com port for serial communication.

These commands will be used for control video stream parameters like exposure, white balance etc.

(I already have one design based on AN75779 which is working good.)

Thanks & Regards,

Akash
