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.)

说明：  利用Labview编程调用函数库实现FFT快速傅里叶变换功能(FFT based on Labview)

该程序可用于控制keithley2600数字源表测量太阳电池的IV曲线。可设置正反扫描次数，实时显示测量结果，并计算Jsc，Voc，FF，eff等电池参数。程序IVnew是总程序，除子程序外，还包括NI公司网站上提供的keithley2600程序包（必要）。(The program can be used to control keithley2600 digital source meter to measure the solar cell IV curve. Can be set to the number of positive and negative scanning, real-time display of measurement results, and calculate the cell parameters of Jsc, Voc, FF, eff. The program ‘IVnew’is the final program.)

ModBus CRC16校验 LabView程序源码(ModBus CRC16 check LabView program source code)

Labview常用板卡驱动，在厂家原有驱动上进行了二次包装，具体包括Agilent（3352X、 34970、DSO1012A）艾德克斯直流电源、凌华（PCI7256、PCI8554、PCI9113）神州飞航（AECCP32ADM、AECDAC8、AECIOC96、AECPDA32）本人水平有限，各位凑合着用。(Labview driver card used in the original manufacturers were driven on secondary packaging, specifically including Agilent (3352X, 34970, DSO1012A) ITECH DC power, Adlink (PCI7256, PCI8554, PCI9113) Shenzhou flight (AECCP32ADM, AECDAC8, AECIOC96, AECPDA32) I level is limited, you make do with.)

说明：  基于Labview的声音信号的采集与存储，小玩意儿(Collection and storage of sound signals)

可以实现Labview与基恩士激光位移传感器实时数据获取(Real-time data acquisition of Labview and Kean laser displacement sensors)

对（极值域均值经验模态分解）EMMD算法的实现(Implementation of EMMD algorithm)

说明：  上位机使用LABVIEW显示心跳曲线， USB采集，单片机采用STM32F103C8，心跳检测芯片采用AD8232，利用单片机自身AD转换(The upper computer uses LabVIEW to display the heartbeat curve, USB to collect, SCM uses stm32f103c8, heartbeat detection chip uses ad8232, SCM uses its own ad conversion)

基于声卡的语音识别，用了LMCC等算法，包括消噪(Sound card based speech recognition, with the LMCC and other algorithms, including the de-noising)
