首先将系统初始化,显示电路工作显示Your Password…,提示用户输入密码,程序调用键盘扫描程序,确认是否有键按下,如果有键按下,将输入数字送入AT89C51单片机与储存值相比较,并同时刷新LCD输出数据,若此时按下E键,则系统执行清除上次数字键输入;如果六位密码输入完毕,并按下A键,程序将输入的六位密码与储存值比较,判断密码是否正确 如果密码正确,则开锁成功,如果密码错误,则LCD显示ERROR!。每输入一位数字或者输出一个结果,蜂鸣器都会有一次响声。-First, the system initialization, the display circuit work shows Your Password ..., prompts the user to enter a password, the program calls the keyboard scanning procedures, confirm whether a key is pressed, if a key is pressed, the input numbers into the AT89C51 microcontroller and storage compared to the value, and also refresh the LCD output data, if at this time press the E key, the system will perform cleanup last numeric keys to enter password if six is completed, and press the A key, the program will enter the six password stored value comparison, determine whether the correct password if the password is correct, unlock successful if the wrong password, the LCD will display ERROR!.
