When the RGB value is 111 display shows the color close to grey,
I thought it was an RGB value has a problem, but I searched the Internet to support only said VHDL eight kinds of color,

VGA RGB is analog signal, may have DA

CodePudding user response:

A da converter is fpga are generally, direct drive can be enough

What's eldest brother can you explain a little bit about the DA, contact the project for the first time don't quite understand,

On VGA interface of RGB are analog signals, rather than digital model, through his control voltage to control the current of the RGB color components of the pixels, the fpga should be digital quantity, he need digital to analog conversion (DA) to become the analog signal received on VGA interface,
