We found a great article over at LucidScience regarding having a microcontroller drive a VGA monitor. This is some pretty cool stuff, when done right! The project explains how to work out the kinks from the typically difficult task of using a microcontroller with a VGA monitor.
“It took some time to learn how the five signals used on an analog VGA connection made an image appear on the screen, but the end results were much better than anticipated, providing a crisp 256 by 240 image on the monitor in 256 colors. Although it does take some intensive cycle accurate assembly programming, the basic coding is not very difficult to understand once you have learned what the monitor expects. In fact, making a microcontroller drive a VGA monitor is much easier than creating a video signal for a television because the VGA monitor does all of the difficult color coding for you as long as you send the video signals and sync pulses at precisely the right time. “Precisely” is the key! “
The article is complete with a list of the parts you’ll need, a quick tutorial, and more so that you can start getting video from your microcontroller!
Hats off to these guys!
