基于STC89C52单片机的纸张计数显示装置设计
<p>笔者设计了基于STC89C52单片机的纸张计数显示装置。系统采用单片机STC89C52作为控制核心,实现通过555振荡电路获取频率值,应用单片机的控制功能和数学运算能力,实现计数和频率换算,用液晶1602显示测试张数并用蜂鸣器发出提示音。测频的基本方法是通过555振荡器以及单片机的定时计数器计数获得频率值,采用最小二乘法进行线性回归,得到1~10张纸的计算公式,通过二次函数回归,得到15张纸
基于IAP单片机电子秤控制系统设计
<p>研发一套家用的电子秤,能够给人们的生活带来方便。本文首先介绍了电子秤的工作原理,然后基于IAP单片机进行了控制系统硬件电路设计,在电子秤硬件系统电路设计的基础上,进行了控制系统软件算法设计。通过得到AD转化量与物体质量的关系,进行最小二乘拟合,得到输出量与转化量之间的关系,通过滤波算法的实现,使得测量的结果更稳定、可靠,并通过OLED液晶进行物体质量显示。</p><p>This paper
光敏传感器智能寻光小车的设计与制作
<p>该设计以STC89C52系列单片机为核心芯片,利用光敏传感器实时接收外界环境光强变化,由单片机感应出信号灯位置,并自动控制小车前往信号灯处。同时该设计带有超声波模块,实时检测小车与前方障碍物的距离,防止小车在行驶过程中与障碍物相撞。该设计采用PWM波形控制电机转速,从而精确控制小车4个电机的转速,在程序中利用相应算法判断小车当前状态,并发出相应指令来控制各个电机的转速。利用Altuim de
