Excuse for my English. I would want to use the card vga in order to pilot
a tv (pal format) in a program for industrial automation.
I would want to realize a video generator using the libsvga.
The modeline is:
modeline "pal" 5.0 278 280 310 320 598 602 618 626 -hsync -vsync -interlaced
The function vga_addmode gives back the big value (1108542220).
I do not succeed to understand where it is the error.
The code:
int nPalMode = 0;
vga_addtiming (5, 278, 280, 310, 320, 598, 602, 618, 626, 0);
nPalMode = vga_addmode (278, 598, 16, 0, 4);
if (!vga_hasmode(VGAMODE))
{
perror("Mode not available.\n");
return -1;
}
You can give some suggestion to me?
Thanks.
