在AVR单片机的控制下，通过WinAVR编译器和makefile的编写，在一个数码管上实时输出键盘输入的字符，当在键盘上按下某一个键时，在数码管上显示该键的值。...

1.通过键盘、LCD来进行超低功耗实验 2 在一段时间内，如果用户没有进行按键操作，系统将进入“睡眠”－－低功耗状态 3 用户按键后，系统从低功耗状态转到正常的工作状态 4 在非低功耗状态下，程序接收键盘按键执行加法器操作(因为键盘和LCD限制不能实现复杂 5 的功能,如乘法、减法、除法等）.-1. Through the keyboard, LCD for ultra low-power experiment 2 over a period of time, if the user does not have keys to the operation, the system will enter a " sleep" - low-power status 3 users button, the system switch from the low-power state to normal working condition 4 in the non-low-power state, the implementation of procedures to receive the keyboard keys adder operation (because the keyboard and the LCD can not limit the complexity of the functions of 5, such as multiplication, subtraction, division, etc.).

具有固定的“红灯―绿灯”转换间隔，并自动切换。它们一般由“通行与禁止时间控制显示、红黄绿三色信号灯和方向指示灯”三部分组成。在交通灯的通行与禁止时间控制显示中，通常要么东西、南北两方向各50秒；要么根据交通规律，东西方向60秒，南北方向40秒，时间控制都是固定的。交通灯的时间控制显示，以固定时间值预先“固化”在单片机中，每次只是以一定周期交替变化。-having fixed the "red light-green light" switch partitions, and automatic switching. They are generally from "prohibiting access and time control, red-yellow-green lights and direction indicator" is composed of three parts. Traffic lights in the passage of time and prohibit control indicates that things are usually either the north-south direction of the two 50 seconds; either on the basis of traffic laws, an east-west direction 60 seconds, 40 seconds north-south direction, the time control are fixed. Traffic lights to the time control, a pre-fixed time value "cured" in SCM, each is a certain cycle alternation.
