Hi everybody ! 

 

I have an altera DE2 with the TRDB2 camera module. 

In order to try to read and write in the SRAM, I have made a LIFO. I can see the mirror effect on my screen, but when I move the camera or when I shake it ^^, I lost the Sync on the VGA.

I have something like the first image on my screen instead of the second. 

I use one of the projects given by terasic. It shows on the screen (vga) the bypass video. 

 

Do you know which signal of the ccd can help me to synchronize the image ? 

Or do you have an other idea ? 

 

Thank you very much for your help !
