LabVIEW脉搏波采集程序，可以控制采集的开始和停止(Pulse acquisition of LabVIEW)

基于声卡的虚拟仪器示波器，通过声卡进行数据采集，再由LABview显示波形。(A virtual instrument oscilloscope based on sound card is used to collect data through a sound card, and then the waveform is displayed by LABview.)

说明：  本代码编制测距传感器的串口通讯接口VI；通过波形图表显示连续读取的测距-时间曲线，并将有效测量范围外的数据滤除。(This code compiles the serial communication interface VI of ranging sensor, displays the continuous read ranging-time curve through waveform chart, and filters out the data outside the effective measurement range.)

说明：  对单个边缘规则的近圆形图像进行拟合，并在原图像的基础上画近似圆(Fitting a single edge regular near-circular image and drawing an approximate circle on the basis of the original image)

基于arm开发板和pc机的tcp/ip通讯，arm开发板作为服务器，pc机作为客户端连接arm板，arm板根据接收的命令开关led灯。其中pc机的客户端程序用labview编写。(Based on arm development board and pc tcp/ip communication, arm development board the connecting arm board as a client as a server, pc machine to arm the board received the command to switch led lights. Pc client program written in labview.)

几个练习使用Labview编程的产物，主要包括：1.正弦扫频信号发生器，可选择频率变化规律（不变、线性、指数变化）以及幅度变化规律（不变、线性、指数变化），还可以通过MathScript节点自定义频率、幅度变化规律； 2.声卡数据采集及频谱分析；3.会说话的小圆点；4.十六进制数布尔数组显示；5.在字符串中显示多种字体；6.钢琴键盘模拟(Several products by practicing Labview programming, including: 1 Sine sweep signal generator, selectable frequency variation (constant, linear, exponential change) and amplitude variation (constant, linear, exponential changes), you can also customize the frequency and amplitude variation through MathScript Node 2 sound card data acquisition and spectrum analysis 3 talking dots 4 hexadecimal to boolean array display 5 display a variety of fonts in the string 6. Piano keyboard simulation )

说明：  用于labview excel写入程序（源代码）(Write program for LabVIEW excel (source code))

说明：  一本很不错的英文LabVIEW书籍，详细阐述了labview的设计思想和范例。(a very nice book talking about how to design a good LabVIEW program.)

基于labview的TCP客户端程序发送主机通常将发送缓冲区中的数据按内存地址从低到?的顺序发出,接收主机把从?络上接到的字节依次保存在接收缓冲区中,也是按内存地址从低到?的顺序保存。 TCP/IP协议规定,?络数据流应采??端字节序,即低地址?字节。 socket API是?层抽象的?络编程接?,适?于各种底层?络协议,如IPv4、 IPv6,以及后?要讲的UNIX Domain Socket。(Based on the TCP client program to send the host LabVIEW will usually send buffer according to the data in the memory address from low to order issued, the receiving host to receive from the network bytes on sequentially stored in the receive buffer, and according to the memory address from low to preservation order. The TCP/IP agreement, network data flow should be endian, low byte address. Socket API is layer abstract network programming interface, suitable in various underlying network protocol, such as IPv4, IPv6, and UNIX Domain Socket to say.)

一个振动测试的程序，能够进行数据采集，还能够对采集的信息进行分析。(A vibration test program, to carry out data collection, but also to the collection of information analysis.)
