（2． 单片机对正确识别的按键进行计数，计数满时，又从零开始计数；
（3． 单片机对计的数值要进行数码显示，计得的数是十进数，含有十位和个位，我们要把十位和个位拆开分别送出这样的十位和个位数值到对应的数码管上显示。如何拆开十位和个位我们可以把所计得的数值对10求余，即可个位数字，对10整除，即可得到十位数字了。
（4． 通过查表方式，分别显示出个位和十位数字。

Description: 用STARES598PCI单板开发机设计一个应用接口芯片作为四个七段LED数码管的输出口，编写一段程序，使8个LED数码管依次闪烁左移显示从输入口的逻辑开关读入的4位数字，闪烁频率为每秒一次。其外，还需实现一些附加功能，比如：可控制左移还是右移；可重新输入另外一个四位数；输入时可回显；以及输入时的十六进制到十进制的转换的等问题。
由此可见，要实现以上的功能，需要8个7段LED数码管和逻辑开关，闪烁的频率为1s。从开关读数，用LED显示。

Description: 数字密码锁具体要求如下：
1. 系统密码设置使用拨位开关sw[7:0]，限定为4位密码；sw[7:6]、sw[5:4]、sw[3:2]、sw[1:0]分别对应从左到右密码的第1、2、3、4位；每一位的取值范围限定在0、1、2三个数中。
2. 用btn[2:0]作为输入键，btn[0]、btn[1]、btn[2]分别对应的有效输入为十进制数0、1、2（由于btn数有限，系统不支持解锁含有数字3的密码）。
3. 输入的密码显示在7段数码显示管对应位上，顺序为从左至右，未输入密码时数码管不显示数字，只有对应位输入密码后数码管才点亮。
4. 输入密码与预存密码相同时，开锁成功，LED灯ld[7]亮起；否则开锁失败，ld[0]亮起。
5. 具有一个复位按键btn[3]。按键后，回到初始状态。
-Digital lock specific requirements are as follows: 1. The system password is set using DIP switches sw [7: 0], is limited to four passwords sw [7: 6], sw [5: 4], sw [3: 2], sw [1: 0], respectively left to right 1,2,3,4 digit password every one of the range is limited to three numbers 0,1,2. 2. Use btn [2: 0] as input keys, btn [0], btn [1], btn [2] corresponding to each active input as a decimal number 0,1,2 (due to the limited number btn, the system does not support the unlock 3 containing numeric password). 3. Enter the password displayed on the 7-segment display tubes corresponding bit on, the order left to right, did not enter a password when no digital display numbers, enter the password only after the corresponding bit digital tube was lit. 4. Enter the same password stored password, unlock success, LED lights ld [7] is lit otherwise the lock fails, ld [0] is illuminated. 5. With a reset button btn [3].
