怕有些地方你不知道是怎么来的,所有我就把完整的程序都给你了。你自己取出你所需要的就好了。因为不同的显示效果还是得靠住函数来实现的。
如果住函数没有写好,那么你的移动方式的函数就很难写了的。希望能给楼主一点灵感。呵呵~
我还有几种效果的,但是所有的效果都必须基于我的那种显示方式。你仔细看下,和你的是不是一样的,显示缓存,各种动画效果就是移动的控制方式了
给你借鉴一下,具体的呢还得根据你的硬件来了。

通过撰写代码来实现。
Proteus中只有5×7和8×8等LED点阵,并没有16×16LED点阵,而在实际应用中,要良好地显示一个汉字,则至少需要16×16点阵。下面我们就首先介绍使用8×8点阵构建16×16点阵的方法,并构建一块16×16LED点阵,用于本例的显示任务。
首先,从Proteus元件库中找到“MATRIX-8X8-RED”元器件,并将四块该元器件放入Proteus文档区编辑窗口中。此时需要注意,如果该元器件保持初始的位置(没有转动方向),我们要首先将其左转90°,使其水平放置,那么此时它的左面8个引脚是其行线,右边8个引脚是其列线(当然,如果你是将右转,则右边8个引脚是行线)。
然后我们将四个元器件对应的行线和列线分别进行连接,使每一条行线引脚接一行16个LED,列线也相同。并注意要将行线和列线引出一定长度的引脚,以便下面我们使用。
然后使用以下代码:
