LabVIEW-IMAQ

用LABVIEW实现保存数据的功能，使数据不会没有了(LABVIEW save data, so that data would not be without)

通过设定扫频范围及采样信息，产生一个chrip 信号。(generate a chirp signal, this vi could be used as a signal generation for free.)

说明：  NI USB-6001电压/阻测试项目源代码（labview2017） 1，使用io触发，自动扫描io上升沿，输入io可选。 2，使用差分方式采样，双通道同时采样，采样数据实时显示。 3，可手动触发采样，采样率，采样数，测试周期可自定义。 4，可保存控件值，运行程序自动加载上次保存的控件值。 5，数据保存到.xls表格，每天新建以年-月-天命名的文件，每个月创建一个文件夹存放数据。 6，测试结果通过USB-6001自带io输出。 真实项目应用源代码!(1. Use IO trigger to scan the rising edge of IO automatically. Input IO is optional. 2. Sampling by differential mode, sampling by two channels at the same time, and real-time display of sampled data. 3. Sampling can be triggered manually. Sampling rate, sampling number and testing period can be defined. 4. The control value can be saved, and the last saved control value can be automatically loaded by the running program. 5. Data is saved to the. xls table. New files named year-month-day are created every day, and a folder is created every month to store data. 6. The test results are output by USB-6001 with io.

用LabVIEW实现对输入音频滤波达到降噪效果(LabVIEW filter of audio signal)

说明：  利用Labviewjinxing 串口数据发送接收(Using LabVIEW to send and receive serial 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.)

labview 代码，特别适合初学者的好东西，特别是工控的孩纸(labview files good thing for beginners especially for engineering controller)

说明：  PCI1020驱动，用于阿尔泰数据采集卡驱动(PCI1020 Driver for Altai Data Acquisition Card Driver)

给出百分制成绩，要求输出成绩等级，90分及以上为A，80分至89分为B，70分至79分为C，60至69分为D，59分及以下为E，小于0分或者高于100分弹出错误提示框。(Given percentile scores, the required output Grade, 90 points and above for A, 80 to 89 are divided into B divided into C, 70 to 79, 60 to 69 is divided into D 59 and for E < 0 or higher than 100 pop-up error message box.)

简单的电子琴labview程序，利用频率播放音乐(Simple keyboard labview program, the use of frequency to play music)
