Hello everyone,

Can anyone explain to me how to generate the R, G, B signals (used in DE2 board) from a gray image?

let me explain. I have an array of pixels (representing a gray image) stored in the DE2 SRAM. How do I generate the 10-bit VGA_R,VGA_G, VGA_B needed from each pixel? How do I generate VGA_R, VGA_G, and VGA_B from a gray pixel that ranges from 0- 255?
