- 用VHDL设计实现秒表功能：秒表功能包括开始/暂停键和清零键，精度要达到0.01秒，所以计数显示共有八个数码管，而每个数码管又有八个管脚，因此采用扫描显示的方法，减少管脚数量。时钟脉冲由最低位给入，采用异步方式驱动更高位的计数，时钟频率应该为100Hz，通过数码管显示，共有八个数码管，所以扫描频率应在100Hz的8倍以上。（付按键消抖代码）-VHDL design with a stopwatch functions: stopwatch features include Start/PAUSE

Project2
- 1、 硬件部分包括AT89C52、LCD1602和4个独立按键 2、 使用定时器0产生10ms的定时中断，作为时钟基准和软件定时器的基准。 3、 系统使用两个软件定时器Tkeyscan和Tdisplay。 Tkeyscan用来独立按键模块的定时扫描，每次扫描结合按键状态机的当前状态判断按键的有效性（消抖）及其时长（长按还是短按）。 Tdisplay用来定时激活LCD1602的显示（200ms一次，可自行修改）。 4、 整个系统在四种状态间流转：DISPL
