利用虚拟仪器开发平台Labview实现串口通信

说明：  labview串口接收、发送（分开）程序以及总通信程序(LabVIEW serial port receive, send (separate) program and general communication program)

自己编的一个生物电信号处理平台，包括相干平均、滤波和傅里叶分析等方法。(Its own series of a biological signal processing platform, including the coherent average, filtering and Fourier analysis methods.)

说明：  通过labview实现停车收费系统，包括串口的选取、读取收费卡号，初始化钱包，进行充值，扣钱，显示余额等功能。(Through LabVIEW, the parking charge system is realized, including the selection of serial port, reading charge card number, initialization of wallet, recharge, deduction, display of balance and other functions.)

程序显示如何在labview中读取键盘、鼠标和操纵杆(recognition of keyboard input, mouse input and joystick input)

此程序是基于labview的FPGA的高速采样教程，特点是利用NI FPGA进行高速采样，采样速度大于10MS/s，里面有丰富的教程，分为几大类，对初学者很友好。各个模块都有分别的vi模块和教程，欢迎大家下载

说明：  设计一个VI来测量温度（保留2位小数），每隔0.25秒测一次，共测定10秒。在数据采集过程中，VI将在波形Chart上实时地显示测量结果。采集过程结束后，在Graph上画出温度数据曲线,并且把测量的温度值以文件的形式存盘， 使用记事本打开文件检查结果是否正确。 存盘格式为： 点数 时间(S) 温度值(度) 1 0.25 78.56 2 0.50 85.32(Design a VI to measure the temperature (keep two decimal places), measured once every 0.25 seconds, 10 seconds were measured. In the data collection process, VI will display the measurement results in real time on the waveform Chart. After the acquisition process, the temperature data in the Graph draw curves, and the temperature measured in the form of document archiving, Use Notepad to open the file to check the result is correct. Save format: Points Time (S) temperature (degrees) &nbsp 1 0.25 78.56 &nbsp 2 0.50 85.32)

说明：  基于Labview的CAN通信系统。包括CAN接受、发送、传输；数据采集；CAN通讯；电池管理系统等。适合相关从业人员交流学习。(Can communication system based on LabVIEW. Including can receiving, sending and transmitting; data collection; can communication; battery management system, etc. It is suitable for relevant practitioners to exchange and study.)

对于无法实现硬件定时的数据卡来说，这个vi提供了软件定时的功能(For data cards that cannot achieve hardware timing, this VI provides software timing capabilities)

labview编写的利用串口与三菱FX系列PLC通讯，可以读写任意输入输出状态，强制M,读写数据寄存器D等。

模拟FM信号的解调子程序，包括下变频、A/D采样、正交解调，最后输出基带信号。(Subroutine analog FM demodulation signal, comprising down-conversion, A/D sampling, orthogonal demodulation, and finally outputs a baseband signal.)
