Pmod VGA confirmation

Question

Hi,

I’m considering about VGA output device.

About  Pmod VGA, There are 2 questions(confirmations).

 

  1. Is this device manufactured from this schematic? Are there any other schematics?

    https://reference.digilentinc.com/_media/reference/pmod/pmodvga/pmodvga_sch.pdf

     

  2. In the following page’s demo, is the View Result Pmod VGA’s output result definitely?

    If it’s possible, please give me other Pmod VGA‘s output result(s).

Thanks.

Hi @roba325,

We provide the manufacture more detailed files that reflect the schematic. We do not publicly provide these files for the Pmod VGA. The schematic covers what IC's, resistors and capacitors are on the Pmod VGA and how they are connected to each other. I have tested the Pmod VGA at the different resolutions without issue. If you look at the vhdl code in top.vhd in the demo attached below you can see that the demo it is coded for multiple resolutions.  Are you wanting pictures of the demo running at the other resolutions?

thank you,

Jon

Yes, I want the pictures of the other resolutions.

Thanks.

Hi @roba325,

Looking at the HDL file, the supported resolutions for the Pmod VGA are:
640x480 at 60 Hz
800x600 at 60 Hz
1280x720 at 60 Hz
1280x1024 at 60 Hz
1920x1080 at 60 Hz

Thanks,

Hi!

Recently I ordered PMOD VGA too.

My PMOD is rev C.

Could you upload schematic file ?

As I understood only one difference is peresented - blue and green are swapped.

 

Thanks!
