ArtyZ7 OV7670 to HDMI Output


elAmericano

Question

 

Hello,

I have had OV7670 design working on older Spartan design that would like to bring into ArtyZ7.  I had purchased from Digilent some Z7 boards to get started with upgrading some of our designs.  

I seem to have some difficulty to convert the RGB data to HDMI output.  I believe issue is with HDMI VHDL, specifically looks like timing.  The HMID output is attached.   When I move object near and far from camera, I can see changing intensities in the "noise".   

OV7670 is running at 25MHZ/50MHZ clks.  I am using 125MHZ for the HDMI - out module to convert the RGB data to tmds.  Also attached is overall structure of project in vivado 2020.

Appreciate any feebback or suggestions.  The goal here is to just get the OV7670 (RGB) to HDMI output from which we can start.
