Hey Peet,
I must say I have exactly the same problem as you have, I'm trying to image a test pattern on the LCD of the NEEK LCD (cyclone III edition) but it flickers and the colors are poor.
I experimented a lot with the PLL settings, because it looks like some clocking problem to me:
- -slower clock values: richer colors and slower flicker
- -faster clock values: poor colors and fast flicker (so the flicker always remains)
In the second post you put a link to the VGA example, but I wasn't able to open it in the SOPC builder (the .sof file worked perfectly on the VGA port) so I couldn't look at the pipeline you created.
Would you mind to give me some help, I'v been strugling with this problem for a few days now... My complete project is in the attchment if you want to have a closer look at some newbies mess :p
Thanks for your time,
Best regards
Hans
