I am using an ARTY 100 with the VGA PMOD and a reduced VGA example project. The issue is that I somehow cannont constantly drive a full 1 level to all of the colour channels to obtain white.
I started with a setting like this here:
vga_red <= h_cntr_reg(10 downto 7);
vga_green <= h_cntr_reg( 6 downto 3);
vga_blue <= v_cntr_reg( 6 downto 3);
to see all possible colour on one screen, but got this output on image 1. It is TOO Yellow so obviously BLUE is to low. I expected a false routing with green or a bad PIN to I exchanged green and blue:
vga_blue <= h_cntr_reg( 6 downto 3);
vga_green <= v_cntr_reg( 6 downto 3);
.. and got the second image. Now suddenly GREEN is to low. This shows, the electrically the pins are driven totally (all 4 bits) of all 4 colours.
But how can this be?
Can I have to do with a bad bank voltage setting as mentioned here?
