1.调用库函数节点（加法）

关于如何使用NI公司USB-6251数据采集卡的参考文献(Companies on how to use NI USB-6251 data acquisition card References)

基于转速环-电流环双闭环控制的直流电机调速系统的labview上位机程序。(The LabVIEW upper computer program of DC motor speed control system based on double closed-loop control of speed-loop and current-loop.)

振动加速度信号的采集程序，程序可以运行，数据自动写入EXCEL表(Vibration acceleration signal acquisition program, the program can be run, the data is automatically written to the EXCEL table)

对信号进行采集和保存，其采样率默认为信号频率的10倍，并将采集到的信号数据保存到电子表格中(Save signal data acquisition and preservation of the signal, the default sampling rate is 10 times the signal frequency, and collected into a spreadsheet)

基于labview的单边傅里叶变换，软件实现，下载即用，无需更改(Based labview unilateral Fourier transform, software, download, no need to change)

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(Use the DAQ Assistant to achieve based on the LABVIEW the oscilloscope, data acquisition card to a variety of waveform display and adjust the scale)

说明：  可实现串口的全双工功能，即接受和发送数据(It can realize full duplex function of serial port, i.e. receiving and sending data)
