上传者: m0_57628341 | 上传时间: 2021-05-06 19:06:16 | 文件大小: 19.57MB | 文件类型: RAR
一种简易的电子密码锁,带有源程序,代码,原理图等资源。本系统由STC89C52单片机系统(主要是STC89C52单片机最小系统)、4×4矩阵键盘、LCD1602显示和报警系统等组成,具有设置、修改六位用户密码、超次报警、超次锁定、密码错误报警等功能(本设计由P0口控制LCD显示,密码正确显示OPEN! 密码错误显示error!超过三次输入错误自动锁定。由P1口控制矩阵键盘含有0-9数字键和A-F功能键。)。除上述基本的密码锁功能外,依据实际的情况还可以添加遥控功能。
