hi,
i want to generate rgb signal by atmega32 to display a picture in vga monitor.
i need information about vga rgb signal characteristics such as frequency, p-to-p voltage and etc
any one help me!

 

You may need something more muscular than an AtMega32 to generate an RGB signal.

The frequency is somewhat variable, as is the quantity of data sent. Think of an 800 x 600 display, and then the 14,400 x 900 I have on my monitor. 480,000 pixels in the first case, 12,960,000 in the last. Then imagine sending all that data at a rate of 72 Hertz.

 

Hello,

On the pages of the epanorama I found this page on videosignal.

There are related links on the bottom.
