51单片机—8*8LED点阵—09—①

今天这个就是简单的控制8*8LED点阵亮0~F这16个数字，暂时不加左移啊~~，上移啊~~以及16*16的点阵呢~~

不过也就这些天都发出来吧~~

呵呵~~

8*8LED点阵显示0~F（这里是静态显示）

注意：

用Proteus仿真开始还真的不知道那个是行，那个是列~~

还得浪费我时间一点点看人家别人的东东~~

1）红色LED上边为列，下边为行（其它颜色的正好相反，上为行，下为列~~）

2）对于红色来说，上边的列最低位在最右边；下边的行最低位也是恰好相反，在最左边（一会看图就知道了，我的就写反了~~正好可以反过来看了~~）

基本上就这么两点的注意事项~~

然后就是程序了：

LED.c

//以前还真的没仿真过LED点阵，今天正好没事情做~~
//注意一点吧，红色的上为列，下为行，其它颜色正好相反~~（前提是我也没记错的情况下~~呵呵，刚试验了一下，对的~~）
