通过labview 2017以及pcix 5922数据采集卡完成数据采集，以及文本存储，还可以从文本中读取波形幅值。(Through lab view 2017 and pcix 5922 data acquisition card to complete data acquisition, as well as text storage, you can also read the waveform amplitude from the text.)

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)

基于Labview的数据存储，将采集到的信号经过GPRS模块串口通信 并存储在指定文件里。(Labview based data storage, the collected signals through the GPRS serial communication module and stored in the specified file.)

说明：  good file for labview beginers which tell every thing aboutdata aquation

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)

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)

可实现字符串滚屏，方便显示数字比较长度字符串(String scroll can be implemented to facilitate the display of numeric comparison length strings)

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.)

利用DAQ助手实现的基于LABVIEW的示波器，可通过数据采集卡实现各种波形显示和尺度调节(DAQ assistant to achieve the use of LABVIEW based oscilloscope, through the data acquisition card to achieve a variety of waveform display and scale adjustment)

用户自行输入所需要的频率和占空比，得到PWM波(Users input the required frequency and duty cycle to get the PWM wave.)
