VGA on the DE1-SoC #10

Open Minorzar opened 8 months ago

Minorzar commented 8 months ago

Must create a working VGA system on the DE1-SoC board.

Minorzar commented 8 months ago

Frequency : 25MHz (standard VGA and better than 25.12...MHz Comm frequency : 60Hz Resolution: Probably the 1280x1024

Minorzar commented 7 months ago

VGA_Sync is now working. Working on VGA_Comm. After that, it should be working fine (without RAM currently)

Minorzar commented 7 months ago

Corrected the code:

Vsync and Hsync were handled wrongly
Wrong bondary in the counting

It has been tested and everything works as expected.

VGA should be working now. Small change of resolution from 640x480 to 1280x1024.

Minorzar commented 7 months ago

So, basically, I fucked up my entire code and nothing is working as expected (which was also a bit expected).

I will go back to 640x480 and hopefully I'll fix everything until thuesday.

Removed useless files from the project, rework the naming of the variable.

For the issue left: x and y are vectors 9 downto 0 but R,G and B are vectors 7 down to 0, need to find a mapping to make x and y conforme to 0 - 255 without division are reduce their uses.

Need to really understand how BLANK_N and SYNC_N are made.

It only took like 3 month, 13 videos on the subject, so many datasheets I lose count and the base code of my tutor but I did it. I guess the main issue was the way I was handling the blank and sync signals.
