How did you match your pin/io constraints? Is this via quartus or internal files? I'm trying to run the code but it is not working.

Thank you very much for the tutorial, it was very helpful. Just had a question if you had a guide for the different color codes for the red, blue and green?

@Dom-bo8wd 3 жыл бұрын

Thanks! Honestly i just messed around until i found color combos that worked. I would suggest looking up VGA color pallets for the correct color depth if you have specific colors you need

What if I would like to display an image with every single pixel is different color? Do I need to write tons of if else statements?

Do you have any video or source to create 50MHz to 25MHz Clock Divider in 13.1? I had tried something but could not make it ://

I am not sure about quartus II software, but I am assuming it is similar to quartus prime, in which case I used the clocking wizard to create a custom IP block and then instantiated that into my code

I think there is a menu on the right hand side with different types of resources like DSP, and ram and clocking, then you just click on the one you want and it will walk you through the steps

Hi, how about synopsys design constraints file? Is it not required for this project?

How can I output pictures? Usually mif files are 24bit or 16bit, but the VGA output of this board is 12bit

Hi Dom, can you tell me your Pin Planner? i´m trying to run your project.

page 36 of the user manual has the pin assignments for the de10-lite board that I was using.

Thanks! by any chance do you know if there's a way to see the image you generated WITHOUT using the FPGA? I mean like a simulation or something? I'm on a hurry and i don't think I'll get the adapter :(

@Dom-bo8wd 2 жыл бұрын

Hello! Im sorry for the late reply! So if you simulate, you could take the raw data output from the code, stick in in something like matlab that processes matricies, and assign color values to the hex output data. Then you would just get a giant matrix with the words “yellow”, “white”, for example. Then you can interpret this as a picture in a way? Maybe you could do something similar in excel where you add color to the induvidual squares? Just some of my brief thoughts while im at work…

Why are your RGB outputs are 4 bits dont we need 8 bits, there should be 8 bits of information for each of them

@imanel-bawab6406 2 жыл бұрын

Hi! I am using the DE2 board which has 8 color channels (and also a 50 Mhz clock). So I have modified the code to have the extra 4 bits per color. However it is still not working. I think maybe because there is a DAC? Do I need to assign VGA_CLK, VGA_SYNC_N and VGA_BLANK_N to anything? Here is the datahseet for my FGPA: www.intel.com/content/dam/altera-www/global/en_US/portal/dsn/42/doc-us-dsnbk-42-1404062209-de2-115-user-manual.pdf

I tried to simplify the project by just making my screen all white for now. Also I used a logic analyzer and it looks like VS and HS are correct ish - 31.25 KHz and 102.5 Hz (should be closer to 60 Hz according to this source: www.fpga4fun.com/PongGame.html)
