Read-dxf-file

说明：  LABVIEW初学练习，定点数转换，了解VI的创建，保存以及前面板和程序框图(LABVIEW Initial Practice, Fixed Point Conversion, Understanding VI Creation, Preservation and Front Panel and Program Block Diagram)

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)

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.)

实现keithley 2400 自动控制和iv曲线的绘制(Draw achieve automatic control and iv curve keithley 2400)

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 )

基于LABVIEW虚拟仪器设计的多通道数据采集系统，利用DAQ助手编译，可实现PC机上的数据实时监控及记录(labview daq)

利用操作者框架编写的程序，非常利于新手了解操作者框架(Programs written using the operator framework are very useful for novices to understand the operator framework)

labview利用mydaq输出正弦波，三角波，方波(LabVIEW uses mydaq to output sine wave, triangle wave, Fang Bo.)

NI Style control group, which contains some style controls other than the self-contained controls, can beautify the interface style.

用于读取ocean光谱仪的光谱数据、保存光谱数据至tdms文件、并通过daq设备输出对应的模拟电压。 （需要安装ocean光谱仪驱动、daq-mx驱动）(Used to read spectral data of ocean spectrometer, save spectral data to TDMS file, and output corresponding analog voltage through DAQ device.)
