Hi,

I need to display something through VGA at 30 fps. I am afraid we can just send data from 60fps as I am unable to find any details such as back and front porch, syncing times when sending 30fps..

Has someone an example displaying something through VGA at 30fps ??

thanks for your help !

Hi,

is "interlacing" an option?

Two half pictures with 60fps give one full picture with 30fps

I am getting frames at 30fps, I need to display it directly on my vga screen. I cant use interlacing as the pixel clock is not the same and I am unable to store the frame in memory (not enough RAM).

I am using a spartan 6 FPGA.
