Description: 1．密码锁有两个密码：一是设计密码，放存在ROM中；另一个是使用密码，存于EEPROM中。
2．.密码锁的密码用4位有效数字，输入超过4位时以最后输入4位数字为准，数字范围由1~6。
3. 用实验板上K1—K6键作密码数字输入键，分别表示1~6数字，K7，K8键为命令键。其中，K7为密码设置键，K8为开锁键。蜂鸣器用作开锁指示。
4. 开机后进入初始状态，显示器显示“— — — —” 且最高一位闪动，闪动位亦表示当前数字输入位，以后每输入一位数字，闪动位向右循环移动。
5．开锁功能：在初始状态下，从K1—K6键输入密码，再按K8键。
若输入密码的最后4位数与存EEPROM的使用密码内容相同或与存于ROM中的设计密码相同，则开锁成功，并用蜂码器发声指示。 否则输入错误返回初始状态。
开锁状态维持 60秒，超过时间，则自动关闭开锁状态，同时停止声音输出。
6.修改密码功能，在开锁状态下，用K1~K6键输入4位新的使用密码，若超过4位数则以最后4位数为准，然后按K7键，则完成密码修改。新密码存到 EEPROM中，覆盖原来的使用密码，且新密码闪动三下，表示修改成功。完成后自动回到初始状态。 若不在开锁状态或在开锁状态下数字键输入不足4位，按K7键就无效，返回初始状态。
-1. There are two locks Password: First, the design of the password, put there in the ROM another is to use the password in stored in EEPROM.
2. . Cipher-lock with the password 4 digits, enter more than four hours to enter the last four figures, the figures range from 1 ~ 6.
3. With the experiment on-board keys K1-K6 password for digital input keys, respectively, 1 ~ 6 figures, K7, K8 key for command button. Which, K7 keys for password setting, K8 for the unlock key. Unlock instructions for the buzzer.
4. Boot into the initial state, the display shows "----" and a maximum of a flashing, flashing-bit digital input also said that the current place for every subsequent importation of a number of mobile flashing circle to the right place.
5. Unlock feature: in the initial state, K1-K6 keys from a password, and then key K8.
If the password and keep the last 4-digit password using the EEPROM or the same content stored in ROM in the design of the same password, then unlock su Platform: |

Description: bascom-avr专业AVR密码锁项目：
该项目是提高AVR的数字密码锁的版本。在这个项目中，你可以改变从系统菜单中的8位数字的密码。也有一个经理的控制面板，一个4位数的PIN码保护，以保护其他人访问这个安全区。这个PIN码是与控制面板多变。这个版本的另一个优势是一个定时的安全级别，当你进入一个不正确的密码3次，系统将约5分钟待机！所有的密码保存在EEPROM存储器。最新的功能真的是changeabe输出 触发器或定时从1到255秒。-Professional AVR Code Lock Project:
This project is improved version of Digital AVR Code Lock. in this project you can change 8 digit password from system menus. also there are a manager control panel that protect with a 4 digit pin code to preserve other people access to this security zone. this pin code is changeable with control panel too. another advantage of this version is a timed security level when you enter a incorrect password for 3 time the system will be standby for about 5 minute! all password saved on EEPROM memory. latest feature is changeabe realy output flip flop or timed from 1 to 255 second.
