AD_count_countdown
说明： 设置3个功能键：当某一功能键被按下后，进入相应的功能模式。3个功能有：
1）8路数据采集功能：通过调节可变电阻实现0-5V的电压输出作为8路输入信号使用，每路信号用2位LED显示采集的结果。报警：任意一路超过某一门限（可自己设定）时，发出报警（声音+灯闪烁，并通过灯指示是哪一路报警），同时停止采集。2）计数功能：利用计数功能键，实现每按一次按键，LED显示加1，从0-99计数。3）秒表功能：只用一个键控制。按下一个按键后时钟启动，从零开始计时，计时间隔0.01秒，再按一次后停止。再按一次后清零。如此循环。
本设计采用2个MAX7221串行驱动2个8路数码管显示，更节省单片机I/O口。(AD、count、countdown)

本文设计了基于加速度传感器的计步器，并通过仿真以及实际调试得到了相应的结果的记录。本实验首先通过加速度传感器检测目标物体的运动，产生脉冲，将脉冲放大后经过施密特触发器整型为方波，并给出了方波的调试电路图。然后编写程序，利用D触发器检测方波的上升沿，当上升沿到来时，计数，并对十位、个位分别编码，然后由使能信号交替控制数码管输出结果。本文给出了仿真以及调试的程序、结果。(This article is designed pedometer-based acceleration sensor and the corresponding results recorded by simulation and debugging. The experiments by first acceleration sensor detects the movement of the target object, generates a pulse, the pulse amplification is a square wave after the Schmitt trigger integer, and gives the the debug circuit diagram of a square wave. Then write procedures, the use of the rising edge of the detection of the square wave of the D flip-flop, when the rising edge, the count, and ten bits are encoded, and then alternately by the enable signal output of the digital control. In this paper, a simulation and debugging procedures, results.)
