用labview做的一个登陆界面的小程序，起到加密的作用(Labview to do with the interface of a small landing procedures, has played the role of encryption)

这是基于LABVIEW的一个小程序，可以完成一个基本的类似于校园网网络的登录的界面，程序中包含多个小的子程序，可以当做练手的素材，有兴趣的可以试试用LABVIEW实现。(This is a small program based on LABVIEW, which can complete a basic login interface similar to the campus network. The program contains several small subroutines, which can be used as training material. Interested ones can try to use LABVIEW.)

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. )

本程序主要应用labview实现神经网络的功能，本程序是BP功能的实现。(The program is mainly applied labview achieve neural network function, this program is BP function.)

说明：  LabVIEW编写的一个信号发生器程序，可选择正弦波、方波、三角波等(A signal generator program written by LabVIEW can select sine wave, square wave, triangle wave, etc.)

通过输入用户名和密码后登录，实现输入正确和错误提示、登录前禁用并灰显读取按钮、登录后启用读取按钮、读取并显示文本文件内容、加密程序框图查看操作。(By inputting user name and password and login, we can input correct and error prompts, disable and gray display the reading button before login, enable the reading button after login, read and display the contents of text files, and view the encrypted program block diagram.)

说明：  labview写的串口调试助手，已经调试通过，使用事件驱动编写的(RS232 debuger by labview)

初学者自学labview小程序参考，包括5判断素数、报数问题、自功率谱处理、跑马灯、模拟汽车控制、登陆界面……各种学习小程序(Beginners learning labview applet reference, including five judgments primes, reported few problems, since the power spectrum processing, marquees, simulated vehicle control, landing a variety of learning applet interface ......)

信号发生器，带扫频，带频率的切换！最小可以0.1HZ。(Frequency sweep signal generator, belt, belt frequency switch! Minimum to 0.1 HZ.)
