labview 程序，实现框选操作，可以用于图像的截图显示VI(Screenshot labview program to achieve marquee operation, can be used to display an image VI)

温度处理系统，温度显示模块 温度报警功能(daq )

将需要保存的数据，保存在EXCEL文档或者TXT文档中。(save you need data for excel or txt file,in NI labview entironment.)

这是在LabVIEW平台下实现的OFDM仿真的代码。非常好的一个在LabVIEW平台下学习通信原理的资料！(This is the LabVIEW platform to achieve the OFDM simulation code. Very good one in the LabVIEW platform to learn Communication Theory information!)

说明：  自己做了一个用labview对CRC32数据进行计算处理的Vi(I made a VI to calculate and process CRC32 data with LabVIEW)

几个练习使用Labview编程的产物，主要包括：1.正弦扫频信号发生器，可选择频率变化规律（不变、线性、指数变化）以及幅度变化规律（不变、线性、指数变化），还可以通过MathScript节点自定义频率、幅度变化规律； 2.声卡数据采集及频谱分析；3.会说话的小圆点；4.十六进制数布尔数组显示；5.在字符串中显示多种字体；6.钢琴键盘模拟(Several products by practicing Labview programming, including: 1 Sine sweep signal generator, selectable frequency variation (constant, linear, exponential change) and amplitude variation (constant, linear, exponential changes), you can also customize the frequency and amplitude variation through MathScript Node 2 sound card data acquisition and spectrum analysis 3 talking dots 4 hexadecimal to boolean array display 5 display a variety of fonts in the string 6. Piano keyboard simulation )

该程序实现了Aloha MAC协议，对于了解协议很有帮助(The program implements Aloha MAC protocol, the protocol is helpful for understanding)

本程序是基于LABWINDOWS/CVI 的，主要是通过串口采集下位机信息，然后显示状态信息并通过串口发送命令字节。(The program is based on LABWINDOWS/CVI.It get message from RS232and display status,then send command by RS232.)

说明：  密码登录系统，基于Access数据库开发，支持管理员、普通用户创建，普通用户只能登录，管理员可对用户进行管理，包括增加用户，删除用户，修改用户等，该系统可移植到任何开发的labview软件，实用性强。(Password login system, based on access database development, supports the creation of administrators and ordinary users. Ordinary users can only log in. Administrators can manage users, including adding users, deleting users, modifying users, etc. the system can be transplanted to any developed LabVIEW software, with strong practicability.)

一个上位机测控软件，采样Labview2011编写，主要功能的和下位机通信，向下位机下发控制指令，并实时显示处理下位机上传的采集数据。(A PC control software, sampling Labview 2011 write, and communicate the main function of the lower down-bit machine control commands issued, and real-time data acquisition display processing lower computer to upload.)
