密码锁:根据设定好的密码，采用二个按键实现密码的输入功能，当密码输入正确之后，锁就打开，如果输入的三次的密码不正确，就锁定按键3秒钟，同时发现报警声，直到没有按键按下3种后，才打开按键锁定功能；否则在3秒钟内仍有按键按下，就重新锁定按键3秒时间并报警-Password Lock: According to set a good password, the password used to achieve two key input function, when to enter the correct password, the lock will open, if entered incorrect password three times, on the lock button 3 seconds, also found that alarm sound, do not press the button until the three kinds of after the Open button lock function otherwise, there is still a matter of seconds in the 3 button press, on the re-lock button 3 seconds time and alarm

电子秒表的设计 1、用系统8253定时器提供的55ms定时单位，设计秒表定时程序。 2、有关系统定时方法： PC机系统中的8253定时器0工作于方式3，外部提供一个时钟作为CLK信号, 频率：f=1.1931816MHz。 定时器0输出方波的频率:fout=1.1931816/65536=18.2Hz。 输出方波的周期Tout=1/18.2=54.945ms。8253A每隔55ms引起一次中断-Electronic stopwatch design one, using the system timer 8253 provides 55ms timing units, design stopwatch timing procedures. 2, the system timing method: PC system timer 0 of 8253 working in the way of 3, to provide an external clock as the CLK signal, the frequency: f = 1.1931816MHz. Timer 0 output square wave frequency: fout = 1.1931816/65536 = 18.2Hz. Cycle square wave output Tout = 1/18.2 = 54.945ms. 8253A every 55ms caused a disruption

这是一个用24C02做的IC卡完整程序,拿来可用的,我用的产品.不多说.自己看吧-This is a 24C02 to do with integrity of the IC card procedure, used to use, I used the products. Little.自己看吧
