VGA port / VHLD

Altera_Forum · ‎01-11-2011

Hi

i am working on video and image processing project.

i have tvp5146 daughter-card and cyclone II device. i have 4bit Y component available with me now.(i set Cb and Cr set to zero in YCbCr (8bits) to set black and white image at VGA port)

i have to put this Y component at R,G and B pins simultaneously to get black and white image at VGA port.

is there any body who guide me how i can do this?

Thank You

Rizwan

Like I said before.

You can make it 8 bits by taking the 4 Y bits and setting them to the MSBs of R G and B, and set the LSBs to 0.

In VHDL:

R <= Y & "0000";

G <= Y & "0000";

B <= Y & "0000";
