Description: 1.设计一个交通灯控制器。
2.利用学习机上的发光二极管，设定东、南、西、北4个方向，各3个灯（红、黄、绿）。交通灯控制器正常工作时，南北方向红灯亮3秒，黄灯闪2秒，绿灯亮3秒，以此类推。东西方向绿灯亮3秒，黄灯闪2秒，红灯亮3秒，以此类推。
3.设定两个紧急按钮，一个控制南北灯，一个控制东西灯。当按下相应的紧急键时，其控制方向的交通灯亮绿灯，其他方向的交通灯亮红灯，至自控键松开，恢复正常交通控制。
-1. Design of a traffic light controller. 2. Use of learning machine on the LED and set the East, South, West, North 4 direction, the three lights (red, yellow, green). Traffic signal controller normal working hours, the north- and south-bound red light three seconds, two seconds flashing yellow light, green light-three seconds, and so on. East-west direction green three seconds, two seconds flashing yellow light, red light three seconds, and so on. 3. Set two emergency buttons, a north-south control lights, a light control things. When pressing the corresponding key emergency, its control the traffic lights green, the other direction, the traffic lights class. Key to loose control and restore normal traffic control.

Description: 密码锁控制器
设计一个密码锁，平时处于等待状态。管理员可以设置或更该密码。如果不预置密码，
密码缺省为“6666”。用户如果需要开锁，按相应的按键进入输入密码状态，输入4位
密码，按下确定键后，若密码正确，锁打开，若密码错误，将提示密码错误，要求重
新输入，三次输入都错误，将发出报警信号。报警后，只有管理员作相应的处理才能
停止报警。用户输入密码时，若输入错误，在按下确定键之前，可以通过按取消键重
新输入。正确开锁后，用户处理完毕后，按下确定键，系统回到等待状态。系统操作
过程中，只要密码锁没有打开，如果1 分钟没有对系统操作，系统回到等待状态。
-Password lock controller
Designed a password lock, waiting in a normal status. Administrators can set up or the password. If you do not preset password,
Default password is "6666." If you need to unlock the user, according to the corresponding status button to enter a password, type 4
Password, press OK, if the password is correct, open the lock, if the wrong password, wrong password will be prompted to request re-
New inputs, the importation of all three errors, will issue a warning signal. Alarm, only the administrator can deal with accordingly
Stop the alarm. Users to enter a password, if the input error, identified in the press before the key can be canceled by pressing the key re-
New input. Unlock right, the user after the treatment, press OK, the system back to waiting status. System Operator
As long as there is no open locks, 1 minutes, if not on the system operation, system status back to wait. Platform: |

Description: 键盘控制器VHDL代码
该控制器实时扫描矩阵键盘的行列，当用户有按键按下时，可以定位到对应的按键并产生一个中断信号-Keyboard controller entity
--
-- The controller scans the columns, cols, by making a different column logic-0
-- therefor the inputs have to be pull-up high. It processes the input, rows, and
-- the pressed key to a corresponding scancode and giving an interrupt
