电子密码锁源程序代码.docVIP

电子密码锁源程序代码 1、可设置4位密码 2、用户可自行设定和修改密码 3、若密码错误，报警5S,连续错3次，报警1分钟 4、锁由继电器模拟 #include AT89X52.H unsigned char ps[]={1,2,3,4,5}; //设定密码 unsigned char code dispbit[]={0xfe,0xfd,0xfb,0xf7, 0xef,0xdf,0xbf,0x7f}; unsigned char code dispcode[]={0x3f,0x06,0x5b,0x4f,0x66, 0x6d,0x7d,0x07,0x7f,0x6f, //数字0~9 0x77,0x7c,0x39,0x5e,0x79,0x71, //字母A~F 0x00,0x40,0x73,0xff}; //字符 -P8. unsigned char dispbuf[8]={18,16,16,16,16,16,16,16}; unsigned char dispcount; //显示计数 unsigned char flashcount; //闪烁计数 unsigned char temp; //临时变量 unsigned char key; //按键 unsigned char keycount; //按键计数 unsigned char pslen=5; //密码长度 unsigned char getps[6]; //得到的密码 bit keyoverflag; //密码输入超位 bit errorflag; //错误标志位 bit rightflag; // 正确标志位 unsigned int second3; unsigned int aa,bb; unsigned int cc; bit okflag; bit alarmflag; //报警标志 bit hibitflag; //高位 unsigned char oka,okb; void main(void) { unsigned char i,j; TMOD=0x01; TH0=(65536-500)/256; //TH0初始化 TL0=(65536-500)%256; //TL0初始化 TR0=1; ET0=1; EA=1; while(1) { P3=0xff; //P3赋值255 P3_4=0; temp=P3; temp=temp 0x0f; if (temp!=0x0f) { for(i=10;i0;i--) for(j=248;j0;j--); temp=P3; temp=temp 0x0f; if (temp!=0x0f) { temp=P3; temp=temp 0x0f; switch(temp) { case 0x0e: key=7; break; case 0x0d: key=8; break; case 0x0b: key=9; break; case 0x07: key=10; break; } temp=P3; // P1_1=
