LabVIEW-samples

labview实现单边傅里叶变换，很好的将时域信号变为频域信号(Labview unilateral Fourier transform，Good time domain signal into frequency domain signal )

说明：  可以对单次输入的信号进行滤波分析和图像显示。同时也具备暂停和历史图像保存的功能。 本程序主要针对的是低频率的未知信号，对于高频率信号最好采用单次采样的方式。(The single input signal can be filtered and analyzed, and the image can be displayed. It also has the functions of pausing and preserving historical images. This program is mainly for low frequency unknown signals, for high frequency signals, the best way to use a single sampling.)

说明：  用虚拟仪器软件labview直接读取微软excel文件中的数据。(Read the excel files by labview !)

数据采集基于NI labview的书记采集程序，采集数据传感器的信号，功能良好(Data acquisition based on NI LabVIEW Secretary collection program, data acquisition sensor signal, function is good.)

This program compute the average filter of an image using the vision assistant

设置电源的电压值的控制程序，可以实现电源的任意给值，和开关控制(Setting the voltage value of the power supply control program, can achieve any of the power supply to the value, and a switch control)

说明：  应用labview实现信号的改进经验模态分解，对初学者有所帮助(Labview is applied to realize the improved empirical mode decomposition of signal, which is helpful for beginners)

labview调用dll实现QR二维码生成，包含dll说明等，可作为子vi直接使用(LabVIEW calls the DLL implementation of QR code generation, including DLL, can be directly used as a sub VI )

说明：  基于计数器和labview高精度软件计时vi实现两个脉冲信号间的高精度时间测量(High precision time measurement between two pulse signals based on counter and LabVIEW high precision software timing VI)

说明：  基于labview的串口通信程序，可通过串口向下位机发送不同的指令(The serial communication program based on LabVIEW can send different instructions to the lower computer through the serial port)
