AVR to VGA D-Sub interface
posted November 4 2010 10:21.44 by Giorgos Lazaridis




RadBrad and Trinity from LucidScience published their new project. In these pages, they demonstrate how can someone send analog data to a VGA monitor, through the classic D-Sub VGA 15 pin connector. The data are generated with the AVR324 running at 20MHz clock. The AVR324 sends an analog signal to the RGB lines of the monitor (Red Green Blue), and controls the horizontal and vertical synchronization lines with the H-Sync and V-Sync, according to the monitor's resolution.

Within this article there is a short explanation of the D-Sub, the schematic circuit and the firmware for the AVR.

      I am going to try to get the best part of this project done over the next few days.

      Cheers!
