利用Labview采集8路信号数据，带注释(Using Labview to collect 8-channel signal data with annotations)

labview中usb raw设备的读取和写入程序 非常有用(labview usb raw device in the read and write process is very useful)

用labview来实现矩阵按键和oled屏幕显示。。(Use labview to achieve matrix keys and oled screen display. )

labview中用程序去产生一个触发事件是个难点，相关的介绍和例子并不多，本程序使用值属性信号结点改变的方法去产生一个事件，实现程序控制产生触发事件的功能，labview开发版本8.2。(labview using the program to generate a trigger event is difficult, relevant examples of the introduction are not many,here we use the value change of the node attribute of the signal to generate an event, the realized the program control functions to generate trigger events, the version of labview development is 8.2 .)

基于LABVIEW的虚拟频谱分析仪，可以对任意信号以及采集卡采集到的信号进行频域分析，同时还加入了时域分析，使功能更为强大。(LABVIEW-based virtual spectrum analyzer can be arbitrary signals and the signal acquisition card for frequency domain analysis, and also joined the time-domain analysis, so that more powerful.)

对LabVIEW进行二次开发，对振动信号进行HHT时频分析(LabVIEW second development, vibration signals HHT time-frequency analysis)

基于Labview的数字滤波器与频谱分析仪 滤波器可以选择是否打开滤波器，可显示波形，可设置滤波器参数，可测量时域、频域的参数，可保存数据、图像；频谱分析仪可显示波形，可测量频域参数(Labview-based digital filter and spectrum analyzer filter can choose whether to open the filter to display the waveform, the filter parameters can be set to measure the time domain, frequency domain parameters, save the data, images spectrum analyzer display waveform, measurable frequency domain parameters)

采用数据保存用户名、密码等数据，同时具备修改、添加、删除用户信息等(User name, password and other data are saved by data, and user information can be modified, added and deleted at the same time)

基于labVIEW的最小二乘法算拟合正弦波计算相位(Calculated based on least squares fitting labVIEW calculated phase sine wave)
