[古董贴][交流]怎样在点阵屏上绘图——基于LCD12864

chinland · 发表于 2008-4-9 14:36:29

觉得还是有多点不赞同的意见会好一点吧。
说实在，我是刚刚接触这些的。楼主的文章很大部分很适合初学者，有部分实在不太容易明白。但是如果有更多不同的声音，那样也许会让我们都知道更多的事情，或者是更多的解决方法吧。

你说的很对哈。这是我早期的作品，很多东西还不成熟，我会重新写一个关于自己DIY GUI的。到时候，很多问题都会得到圆满的解决。

ivws · 发表于 2008-9-26 12:18:38

请教楼主....最近按你给的伪代码写出了画线程序 .....
画出的效果不是很理想....从左到右画可以显示....从右到左...就不显示.... 比如画一条线..X1 = 1; Y1 = 1; X2 = 2; Y2 = 63;
效果很差....可否看一下你的源程序.
void PlotLine(uchar x1, uchar y1, uchar x2, uchar y2, uchar type)
 {
     schar dx = x2 - x1;                                   //求距离差
         schar dy = y2 - y1;                           
         
         uchar ix = (dx >= 0)? dx: -dx;                        //求绝对值
         uchar iy = (dy >= 0)? dy: -dy;
         
         uchar x = 0;                                          //数据清零
         uchar y = 0;
         
         uchar inc;         
         uchar count = iy;                                     //取最大值
         
         schar xn = 0;                                         //增长方向
         schar yn = 0; 
         
         if (dy > 0) yn = 1;
         if (dy < 0) yn = -1;  
         
         if (dx > 0) xn = 1;
         if (dx < 0) xn = -1;
         
         if (ix > iy) count = ix;
         
         inc = count;
         
         do
          {
           x += ix;
           y += iy;
        
           if (x > inc)
            {
                 x -= inc;
                 x1 += xn;
                }
                
           if (y > inc)
            {
                 y -= inc;
                 y1 += yn;
                }        
          // 画点
          }
          
         while (count--);
