XY图做时间做X轴，Labview程序（紫薯布丁）(X, y graph time X axis)

虚拟仪器Labview：FFT、采样、加窗、互相关分析仪、滤波器、谱分析、随机信号分析仪、信号发生器.exe自谱与自相关分析.exe的可执行程序(FFT, sampling, windowing, cross-correlation analysis instrument, filter, spectrum analysis, the random signal analyzer, signal generator exe autospectrum autocorrelation analysis exe executable program)

数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresponding PWM duty cycle, and finally the speed of the motor is controlled.)

摘要：以实际工程为背景，介绍了在I丑bwindows／CVI环境下，基于ActiveX技术访问Microsoft Excel 2003的方法，以及创建 自动化仪器驱动器的方法。详细阐述了访问Excel具体函数的使用方法，实现了对Excel的访问。通过该工程实例，说明 了本方法具有重要的工程实用价值。(Abstract：The approach of accessing to Microsoft Excel 2003 based on ActiveX technology in LabWindows／CVI environment is intrt~ uced，in 8cN~ence，the establishments of driving scheme for automatic instruments are presented in detail．To realize the access to Excel，the operations of accessing to the real functions are intensively illustrated as wel1．Th e experiments in the real environment demonstrate that this method illustrated here is of great value for practical applications．)

labview菜单使用方法，包括菜单的创建，事件结构的编写(labview menu use, including the creation of menus, event structures prepared)

用LabVIEW做了一个简单的菜单文件 可以实现下拉菜单选择不同的页面(Making a simple menu file with LabVIEW can realize pull-down menu to select different pages)

从USB串口读取GPS经纬度信息，调用百度地图显示当前位置(Read the GPS latitude and longitude information from the USB serial port, and call the Baidu map to show the current position)

使用生产者与消费者模式模拟ATM机，可以实现存取款及余额查看功能(Using Labview to simulate ATM.)

本文件为labview源文件，实现labview和PLC的通讯。(This document is labview source file, realize labview and PLC communications.)

LabVIEW源程序,数量很多,内容全面,相信对LabVIEW初学者帮助很大.(LabVIEW source, volume, as a comprehensive, believe that the right LabVIEW beginners great help.)
