Practica-1

说明：  控制转台旋转角度情况下，7路光功率计同时探测光强变化，联谊和thorlabs设备，需导入子vi。(Under the condition of controlling the rotation Angle of the turntable, the 7-channel optical power meter can simultaneously detect the change of light intensity.)

信号发生器，基于labview平台的虚拟仪器，具有输出正弦波方波加入噪声等功能。(The signal generator)

控制台达电机旋转的简易例程，其实就是给台达电机发命令哪(Simple console routines of motor rotation)

通过labview控制信号发生器和锁相放大器进行共振频率检测的程序。freq test.vi实现信号发生器的频率扫描，lockin test.vi 实现锁相放大器的参数设定，数据采集.vi实现锁相数据的采集，waveform arrays to file实现波形数据到文件数据的转换。共振频率测试.vi实现晶振等共振频率的测试(Resonance frequency detection procedures performed by labview control signal generator and lock-in amplifier. freq test.vi achieve frequency sweep signal generator, lockin test.vi setting parameters to achieve lock-in amplifier, a data acquisition. vi achieve phase lock data acquisition, waveform arrays to file converted waveform data to achieve document data. The resonance frequency of the test. Vi achieve crystal and other resonant frequency test)

使用labview实现中断访问串口，使用消息队列方式传递数据。(Use labview realize interrupt visit, use the message queue serial port style to deliver data. )

说明：  基于LabVIEW的二维码生成,用的是C++生成的DLL，然后调用生成(QR code generation based on LabVIEW)

关于labview的一些程序，用于了解机器视觉的(Some programs about LabVIEW)

Labview+USRP平台下实现OFDM收发信号(Implementation of OFDM transceiver signal under Labview+USRP platform)

创建一个vi，实现对按钮状态的指示和按钮“按下”持续时间的简单计算功能，按下按钮时，对应的指示灯亮，对应的数字量显示控件中开始计时。松开按钮时，指示灯灭，计时停止。(Create a VI to realize the instructions of the button state and the simple computing function of the button "press" the duration. When the button is pressed, the corresponding indicator lights up, and the corresponding digital quantity displays the timing in the control. When the button is loosened, the light is put out and the timing is stopped.)

说明：  这是一个初学者可以学习的小实战例子，希望大家可以下载并尝试自己编写小程序提高基础能力(This is a small practical example that beginners can learn)
