Description: 4×4键盘及8位数码管显示构成的电子密码锁 用8位数码管组成显示电路提示信息，当输入密码时，只显示“8.”，当密码位数输入完毕按下确认键时，对输入的密码与设定的密码进行比较，若密码正确，则门开，此处用LED发光二极管亮一秒钟做为提示，同时发出“叮咚”声；若密码不正确，禁止按键输入3秒，同时发出“嘀、嘀”报警声；若在3秒之内仍有按键按下，则禁止按键输入3秒被重新禁止-4 × 4 keypad and 8-bit digital tube display constitutes an electronic code lock with an 8-bit digital tube display circuit message, when the input password, only shows " 8." , When the median enter password press the confirm button when finished to enter the password with the password set for comparison, if the password is correct, then the door opened here with a bright LED light-emitting diodes as a matter of seconds suggests that at the same time issued a " ding dong" sound if the password is not correct, the prohibition of keystrokes 3 seconds, at the same time issued a " 嘀,嘀" alarm sound if there are still three seconds of pressing the button, the button to prohibit re-importation ban on 3 seconds

Description: 用单片机做的USB开发板的键盘程序
开发板上共有8个按键，功能分别为：
K1:左Ctrl键 K2:左Shift键 K3:左Alt键 K4:0键
K5:1键 K6:2键 K7:Caps Lock键 K8:Num Lock键
按键功能测试：
同时按下K1和K2可做输入法切换，这跟键盘上的两个键功能一样的。
K7可打开大写字母锁定，同时LED2亮起。K8是小数字键盘锁定键，
当数字键盘打开时，LED1亮起，这时可用K4，K5，K6输入数字。
请留意EDN板上的LED会跟你自己的键盘上的LED灯同步。不管按哪块
键盘切换都是如此。不过按住切换键不放，可能会导致两块键盘之间
的LED失步。-MCU development board to do the keyboard USB development board a total of eight buttons, functions, respectively: K1: Left Ctrl key K2: the left Shift key K3: left Alt key K4: 0 key K5: 1 key K6: 2 key K7: Caps Lock key K8: Num Lock key button function test: Press the K1 and K2 at the same time can switch the input method, which is two keys on the keyboard functions the same. K7 can be locked open capital letters at the same time turn on LED2. K8 is a small numeric keypad lock, when the numeric keypad open, LED1 lights when available K4, K5, K6 digital input. Please pay attention to the LED board EDN will be with your own LED lights on the keyboard simultaneously. Regardless of the keyboard by switching哪块true. Hold down the key switch, however, may result between the two LED keyboard out-of-step.

Description: 这是一款适合于初学者的4*4键盘扫描程序。本程序虽然在网路上已经有很多的实例，但是在本程序中本人采用了一种其他的算法。并且加入了防抖程序。适合初学者使用学习。。。同样，本程序是用于MEGA16单片上实现的-This is suitable for beginners of a 4* 4 keypad scanner. Although this process has been on the Internet there are many examples, but in the process I used one of the other algorithms. And joined the Anti-shake procedure. Suitable for beginners to learn. . .
