jpeyron Posted December 28, 2017 Share Posted December 28, 2017 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 top.vhd Link to comment Share on other sites More sharing options...

JColvin Posted January 9, 2018 Share Posted January 9, 2018 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, JColvin Link to comment Share on other sites More sharing options...
toshas Posted January 19, 2018 Share Posted January 19, 2018 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! Link to comment Share on other sites More sharing options...
JColvin Posted January 19, 2018 Share Posted January 19, 2018 Hello @ululuk, The Pmod VGA schematic (rev C) is now available on the Pmod VGA Resource Center on the right hand side under Documentation. The rev C schematic accurately reflects the rev C version of the Pmod. Let me know if you have any questions. Thanks, JColvin Link to comment Share on other sites More sharing options...
toshas Posted January 19, 2018 Share Posted January 19, 2018 Thanks a lot! Usually I use link from store page https://store.digilentinc.com/pmod-vga-video-graphics-array/ . It leads to rev B https://reference.digilentinc.com/reference/pmod/pmodvga/schematic . And there is one strange moment in rev C schematic : no VCC net to VCC pins, only GND exist. Looks like a mistake. Link to comment Share on other sites More sharing options...
JColvin Posted January 19, 2018 Share Posted January 19, 2018 Hi @ululuk, Good catch, I hadn't noticed that. I'll get the request in to get that updated soon. Thanks, JColvin Link to comment Share on other sites More sharing options...
Question

Hi,
I’m considering about VGA output device.
About Pmod VGA, There are 2 questions(confirmations).
Is this device manufactured from this schematic? Are there any other schematics?
https://reference.digilentinc.com/_media/reference/pmod/pmodvga/pmodvga_sch.pdf
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).
