(1)JPG圖片顯示在屏幕的焦點代碼以下:

void sys_draw_jpg(u16 vp,u8 *jpg_data,u32 data_len)

{

        u32 i;

        for(i=0;i<data_len;i++)

        {

                if((jpg_data==0xFF)&&(jpg_data[i+1]==0xD8))

                        break;

         }

                if(i==data_len)

                        return;

                data_len = (data_len-i)/2+1;

                sys_write_vp(vp+2,jpg_data+i,data_len);

                data_len |= 0x5AA50000;

                sys_write_vp(vp,(u8*)&data_len,2);

}
