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.).
