TTLAPI

labview存储数据子函数，自动生成excel 文件,excel文件以时间命名(by using the labview to storage the data,and the vi can generate the excel automaticlly)

高端大方的多行列表控件，机场标牌效果，非常漂亮(High-end generous multi-line list controls, airport signage effect, very nice)

labvIEW程序，可以把一个数组转化为一个簇的形式(labvIEW program, you can put an array into a cluster)

所写的Labview程序可一次性计算出轴承的故障特征频率，方便实用(Written Labview program can calculate a one-time fault characteristic frequency of the bearing, convenient and practical)

本系统可做自动控制原理中的时域分析仿真实验，系统特性如下： 1：可选择仿真系统为一阶、二阶、任意阶 2：可选择信号源为正弦波、三角波、锯齿波、方波（可模拟阶跃信号），并可调节信号源频率、幅值、相位、偏移、方波占空比 3：可选择信号采样率及采样数 4：自动计算传递函数 5：自动计算时域响应参数（增益系数、上升时间、峰值、峰值时间、稳定时间、超调量） 6：波形图同时显示原始信号和响应信号 注：使用本系统需安装labview控制设计与仿真库(The system can do automatic control theory in the time-domain analysis simulation, the system behaves as follows: 1: simulation system can be selected for the first, second, any order 2: select the signal source is a sine wave, triangle wave, sawtooth, square wave (analog step signal), and can adjust the signal source frequency, amplitude, phase, offset, duty cycle square wave 3: the the optional signal sampling rate and the number of samples 4: automatic calculation of the transfer function 5: Automatic calculation domain response parameters (gain coefficient, rise time, peak, peak time, settling time, overshoot) 6: waveform diagram shows both the original signal and the response signal Note: Use the system to be installed LabVIEW Control Design and Simulation library)

说明：  运用Labview实现温湿度传感器的应用，方便快捷，简单实用。(Using Labview to realize the application of temperature and humidity sensor is convenient, fast, simple and practical.)

自己编写的labview excel的读写和编辑(I have written labview excel in reading, writing and editing)

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)

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.)

用keithley2400电源测量电阻的labview程序，用于测量I-V曲线和两线法测电阻(Measuring resistance with Keithley2400 power supply)
