A reader provides some additional info to complement this week's "How To" on designing a simple VGA interface.
Have you read the recent "How To" titled Design Recipes for FPGAs – A Simple VGA Interface? Well, a regular contributor to our discussions – Jay Dowling – just emailed me to say:
Hi Max, I saw your VGA display article so I uploaded a few related spreadsheets to my yahoo group:
There is one that gives IRE values and voltages for the standard color bars in various color spaces in 8 and 10 bits (based on the book Video Demystified). Another one has a collection of H/V/P timing information for various standard resolutions (from various sources). And there is one that allows you to calculate any resolution and timing set that still conforms to VGA specs so any display will work with them (I found the original on the web somewhere and I cleaned it up and added a few things to it).
Great. Thanks a lot Jay. I'm sure this is going to come in useful for a lot of folks, including myself.
