猜数字游戏机



这是一个让玩家在一定的规则和系统提示下，推算一个随机产生的四位数的游戏，这个四位数的各位都不相同。游戏规则如下：

系统　　随机产生一个四位数，数码各不相同，玩家通过键盘依次输入4位数，输错可以按退格键修改，输完按确认键确认，然后系统判断，如果猜的数字有x个数字与答案数码相同并且位置相同（该条件代号用A表示），有y个数字与答案数码相同但位置不同（该条件代号用B表示），就输出xAyB。例如答案是2639，输入1692，那么确认后显示结果1A2B。然后玩家通过分析再次输入新的数字，直到猜中答案。游戏每局提供10次机会，并且有100秒倒计时，以增加玩家的压力。

本系统采用CPLD作为主控平台，另外用单片机通过I2C总线与单片机通信实现4个数码管的输出。
