hi everybody http://forum.niosforum.com/work2/style_emoticons/<#emo_dir#>/smile.gif

i want to do my new board based on reference design auto_graphics_ref_design-v1.0.4

and i found to many c files in design and it&#39;s dificault to understand all software design http://forum.niosforum.com/work2/style_emoticons/<#emo_dir#>/sad.gif

i just want to do my custom animation with two video pages where i move triangle and i don&#39;t understand how to do it correct without blinking.

maybe someone have an experience with this ref design - help me please to make first steps.

here is my program - it work but i not understant a too many strings.

void my_main()

{

point quad[4];

alt_u32 i, j, x1, y1, x2, y2;

alt_32 rects[8] = {80, 160, 240, 320, 400, 480, 560, 640};

alt_32 num_objects = 500;

printf("my triangle\n\n");

if ((bmpfile = fopen("/mnt/rozipfs/backdrop.bmp","rb")) == null) {

printf("unable to open backdrop.bmp\n");

return ;

}

bmpto565(bmpfile, framebuffer3); // why i don&#39;t see any pictute ?

// clear frame buffers

vga_paint_screen_8bit(p_trans, framebuffer11);

//////////////////////////////

lcd_sync();

// set up dma for layer 2 from frame buffer 11

lcddodma8(2, framebuffer11, screensize, 0x2f);

lcd.const_alpha2 = 0x3f;

// set up dma for layer 3 from frame buffer 12

lcddodma8(4, framebuffer12, screensize, 0x3f);

lcd_sync();

// enable dma and turn on layers

lcdlayers(0x04);

// i copy this strings from sources and i don&#39;t understand what they mean - can some one to write comments ?

//////////////////////////////

quad[0].x = 10;

quad[0].y = 10;

quad[1].x = 100;

quad[1].y = 10;

quad[2].x = 150;

quad[2].y = 100;

quad[3].x = 0;

quad[3].y = 0;

for (i=0;i<512;i++)

{

quad[0].x = i;

quad[0].y = i;

quad[1].x = 100;

quad[1].y = 10;

quad[2].x = 150;

quad[2].y = 100;

lcd_sync();

vga_draw_polygon_8bit(quad, 3, 1, p_green, do_fill, framebuffer11);

//here i draw triangle but how to draw it with 2 videopages mechansim ?

}

could you tell me ..

when you use this reference design , the picture is normal ?

I use this reference design, there is some green mask to cover the picture..

do you have this problem?
