An Overview Of Creating VGA With VHDL
VGA timing signals require sub microsecond precision. If the timing is off the picture will not display. The UP2 board has offered us a 'perfect' clock and circuitry for getting VGA display up and running with minimal complication.
What To Do Now
There are many directions you can take after understanding the VHDL code for generating such a simple VGA output. You can explore how to create different colors, different shapes. You will be surprised at how complex it can be to create simple shapes like triangles, pentagons or circles.
Conclusion
This tutorial has a redeeming value in that you create vga signals that work on any and all vga monitors, LCDs and projectors. There is plenty of room to continue working past what is done in this tutorial and I feel this tutorial has given the reader a solid base for VGA generation.
If you have any further questions, I implore you...don't be shy, take a look at the forums or ask a question there. I check them out regularly and love getting comments & questions.
