51单片机环境下，设计密码锁（掉电可记忆密码）的源代码-coded lock

密码锁（掉电可记忆密码） 本程序结合了24C02存储器的存储功能，可以掉电保存密码。-Lock (down to remembering passwords) This program combines a storage 24C02 memory can be powered down to save the password.

基于51单片机的电子密码锁设计，用E2PROM存储数据，掉电记忆(Design of electronic cipher lock based on 51 single chip microcomputer, storage of data with E2PROM, power down memory)
