代码说明:

  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.)

  • LED
    at89c51 的跑马灯程序. 把LED灯连接到端口0然后用烧录到单片机就行了.(This is an AT89C51 LED chaser program. Connect LEDs to port 1 and then use KEIL to compile the leds1.C into a .hex file then download t to your microcontroller.)

  • 8、交通灯
    绿灯亮时,准许车辆通行,黄灯闪烁时,已越过停止线的车辆可以继续通行;没有通过的应该减速慢行到停车线前停止并等待,红灯亮时,禁止车辆通行。给行人看的叫人行横道灯,通常指由红、绿(绿为蓝绿)二种颜色灯组成用来指挥交通通行的信号灯,红灯停,绿灯行。(When the green light is on, the vehicle is allowed to pass. When the yellow light is flashing, the vehicles that have crossed the stop line can continue to pass.You should slow down to stop and wait at the stop line. No traffic is allowed when the red light is on.Pedestrian crossing lights for pedestrians, usually denoted by red, green (green, blue, green), two color lamps used to direct traffic signals, stop at red lights and green.)
