Hello people,

Thanks to all of you for all the help you have given to me.

I am trying to display characters on VGA using Altera DE0.

First I need to display the words "Simon Says" on top of the screen while displaying color squares in the middle. I do have the squares but I don't know how to get the phrase.

Second, I want to display a more static image kind of "Fail" or "Win" message. My professor told me I could use MATLAB to generate a .mif file from the .jpg. After that, initiate a ROM and display that, but I can't find information about how to do that.

Any idea?

Regards,

Luis.
 

The professor is suggesting you convert a jpg image into the equivalent image that you will display on the DE0, though I suspect you would be better off using some sort of bit mapped graphics image as it would translate easier to a ROM.
 

I suggested not using JPEG as that will require decompression of the image. You could use MATLAB like your professor suggested. As the screen you are displaying the image on you have to have an image that represents each pixel of the display. That's why I suggested using some sort of bit mapped graphics for the text.

How to do all that? You'll have to learn something you don't already know, but isn't that the point. Perhaps someone else with direct experience with doing this can give you detailed pointers.

Regards.
