Hello everyone!
I'm relatively new with FPGA design, so sorry if this is rather a basic or common question. Unfortunately I wasn't able to find any answers to my troubles (for my particular board) after several days of searching.
I am working on an image processing project with my Altera DE1-SoC board and the first step is to display an image on the VGA display. To configure the display before dealing with the image itself, I first decided to program random patterns in the 640x480@60Hz VGA monitor. I used the first part of this code as the basis and tried running it on the board with the DE1 pin configuration:
https://www.fpga4fun.com/PongGame.html
The pins I am using are VGA_R, VGA_G, VGA_B, VGA_VS, VGA_HS as per example.
The indicator light on my monitor is green, suggesting there is some communication between the board and the display (if the timing specs are incorrect, this light is red). However, I only see black on the display, no matter what I set the RGB pins as. :-( Can anyone more experienced offer any suggestions as to why this is the case? Am I forgetting something obvious?
Thanks!
