说明：  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)

基于Labview的电子钢琴设计，通过对声音频率的设置，实现发声及演奏功能(Labview-based electronic piano design, set to the frequency of the sound, vocal and performance features)

实现labview的串口通讯，控制下位机两路继电器，以及控制电机旋转。(Achieve labview serial communication, the next crew to control two relays, as well as to control the motor rotation.)

在laview利用动态链接库dll函数节点调用c语言实现加法运算(In LabVIEW, we use dynamic link library DLL function node to call C language to add operation.)

将摄氏度转化为华氏度。用户给出一个摄氏度温度数值，程序自动将其转化为华氏度值。(Degrees Celsius into Fahrenheit. The user is given a degree Celsius temperature value, the program will automatically convert to Fahrenheit value.)

在vc环境下调用labview下生成的dll库在vc环境下调用labview下生成的dll库(Vc calls in labview environment generated dll library vc environment in labview generated call dll library)

实现Kvaser的CAN通讯，能实现简单的读写CAN信号。(The CAN communication of Kvaser can be realized, and CAN signal can be read and written simply.)

本设计采用了虚拟的NI-PCI 6221数据采集卡，利用虚拟仪器及其相关技术实现了多通道数据采集。该系统具有多路采集、实时显示、存储管理与密码保护等功能。(This design uses a virtual NI-PCI 6221 data acquisition card, using virtual instruments and related technologies to achieve multi-channel data acquisition. The system has many functions, such as multi-channel acquisition, real-time display, storage management and password protection.)

I was suprised LabVIEW didn t had the CRC32. So I made it, http://en.wikipedia....edundancy_check, http://www.ietf.org/rfc/rfc1952.txt. It can take a array of U32, one element of U32 or a string. When needed I can create more CRC checks, CRC8, CRC16, etc... but CRC32 is the most used one I readed.

所写的Labview程序可一次性计算出轴承的故障特征频率，方便实用(Written Labview program can calculate a one-time fault characteristic frequency of the bearing, convenient and practical)
