用I2c点亮12864液晶显示，任意位置(Light 12864 liquid crystal display with I2c, any position)

某贸易中心共10层，设有载客电梯1部。为了处理问题的方便，有以下的限定条件： 　　（1） 电梯的运行规则是：可到达每层。 　　（2） 每部电梯的最大乘员量均为K人（K值可以根据仿真情况在10~20人之间确定）。 　　（3） 仿真开始时，电梯随机地处于其符合运行规则的任意一层，为空梯。 　　（4） 仿真开始后，有N人(>20人)在该国际贸易中心的1层，开始乘梯活动。 　　（5） 每个人初次所要到达的楼层是随机的，开始在底层等待电梯到来。 　　（6） 每个人乘坐电梯到达指定楼层后，再随机地去往另一楼层，依此类推，当每人乘坐过L次（L值可以根据仿真情况在3~10次之间确定）电梯后，第L+1次为下至底层并结束乘梯行为。到所有人结束乘梯行为时，本次仿真结束。 　　（7） 电梯运行速度为S秒/层（S值可以根据仿真情况在1~5之间确定），每人上下时间为T秒（T值可以根据仿真情况在2~10之间确定）。 　　（8） 电梯运行的方向由先发出请求者决定，不允许后发出请求者改变电梯的当前运行方向，除非是未被请求的空梯。(a total of 10 layers, with a passenger elevator. To address the issue of convenience, have the following qualifications : (a) lift the operating rules is : can be reached on each floor. (2) each lift crew of the largest volume of all K (K value can be based on the simulation of the 10 to 20 between determined). (3) simulation at the beginning, randomly located in the lift line with its rules of operation arbitrary layer of air staircase. (4) simulation began, a N (gt; 20) at the International Trade Center in one layer, started by ladder activities. (5) Each person must first reach the floors are random, in the bottom wait for the elevator arrived. (6) Each person taken the lift arrived at the designated floor and then another random foot to the floor, and so on, when each rode L (L value c)

显示屏的设计，是用51单片机做的，对初学的好有用(display is designed to use 51 microcontroller done, a good pair of useful learning)

名称：门禁模拟 模拟现实中门禁系统，可以输入密码进入也可以呼叫住户，再由住户按下开门按键 实现改密码功能，密码保存在24c02中能保证掉电不丢失密码。八个LED灯分别代表 8家住户，其中开门按键为共用，还带有忘记密码恢复按钮，模拟恢复出厂设置， 显示部分为LCD1602。程序共分为3种模式，分别为 等待输入 密码修改 呼叫住户 3种模式，其中等待输入是主要状态，所以在进入密码修改 呼叫住户模式后如果 长时间没有操作能自己切换到等待输入模式。(Name: Access Analog Simulating real access control system, you can also enter a password to enter the call households, again by pressing the open button households Implement change password function, the password stored in the 24c02 can guarantee non-volatile password. Eight LED lights represent 8 households, which opened the door keys are shared, but also with forgotten password recovery button, analog restore factory settings, Display part LCD1602. Program is divided into three modes, namely, waiting for a password to modify call households 3 modes, which is the main input wait state, so call households entering the password change mode if Their long time operation can be switched to the standby input mode.)
