51單片機12864顯示的電子密碼鎖源碼

ID:372470 · 發表于 2018-8-1 15:21

這是一個基于STC89C52的指紋識別和鍵盤密碼鎖，里面包括程
1.當要想從標志位中退出來就一定要知道程序當前在哪個標志位中讀取，然后就是在這個里面設定退出方可，
否則是不能使用的，相當于是沒有一樣。

單片機源程序如下:

/*************************************************************************************
密碼鎖，可以改個人密碼和管理員密碼的一個基于單片機的鎖。
按鍵值碼： 1 2 3 set 輸入密碼只能按0~9，10位確定鍵，11位取消鍵（輸入密碼小
4 5 6 ↑ 于8時取消輸入的密碼），12是時鐘功能鍵，13是時鐘“+”，
7 8 9 ↓ 14是時鐘“-”，15改密碼的時候的確定鍵
ok 0 c fun
