soundcardoscillograph

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 )

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.)

示波器的设计，基本上满足日常的使用。可以自动调整频率等功能(Design of Oscilloscope)

说明：  Labview生成DLL文件的教程，适用于dll开发等。(LabVIEW to generate DLL file tutorial, suitable for DLL development and so on.)

调用dll文件截取最前端窗口的图像，调用需要等待200ms(Calling DLL file to intercept the front-end image)

labview编写的振动信号数据采集处理，编写的振动信号数据采集处理。(signal collection, signal processing with Labview, Labview data acquisition of vibration signal processing.)

LabVIEW客户端第二界面，是实现LabVIEW TCP通信的客户端第二个界面。(The LabVIEW client second interface is the second interface of the LabVIEW TCP communication client.)

利用MyRio，发出指定脉冲数，来控制电机(Using MyRio, the number of the specified pulse is issued to control the motor.)

晶体的真空调频设备控制VI，通过串口于西门子PLC的通信。实现现场测量参数返回、控制命令下达、动作参数下达PLC、显示测量结果。(I edit the vacuum device control program, the programming language is LABVIEW, thanks to the example of network gods. Upload this document, hoping to provide help for later generations.)

基于labview的信号发生器以及信号滤波器，功能强大，以及界面很漂亮(Signal generators and signal filter labview based and powerful, and the interface is very beautiful)
