8×8led点阵屏仿电梯数字滚动显示.c

单片机C语言程序设计实训100例--基于AVR+PROTEUS仿真

//-----------------------------------------------------------------
//  名称: 8×8LED点阵屏仿电梯数字滚动显示
//-----------------------------------------------------------------
//  说明: 本例模拟了电梯显示屏上下滚动显示楼层的效果,当目标楼层大于
//   	  当前楼层时将向上滚动显示,反之则向下滚动显示,到达目标楼层时
//        将发出蜂鸣声.
