DAQmx-signal-sampling

说明：  上位机使用LABVIEW显示心跳曲线， USB采集，单片机采用STM32F103C8，心跳检测芯片采用AD8232，利用单片机自身AD转换(The upper computer uses LabVIEW to display the heartbeat curve, USB to collect, SCM uses stm32f103c8, heartbeat detection chip uses ad8232, SCM uses its own ad conversion)

简单使用modbus实现仪表的数据读取，实现串口通讯(Simple to use modbus to achieve the instrument' s data to read, and serial communication)

说明：  基于NI的LABVIEW开发平台的谐波分析(Harmonic Analysis of LABVIEW Development Platform Based on NI)

LabVIEW 机器人路径规划方面的例子，仔细研究很有用(LabVIEW pathplanning)

使用生产者与消费者模式模拟ATM机，可以实现存取款及余额查看功能(Using Labview to simulate ATM.)

对信号进行采集和保存，其采样率默认为信号频率的10倍，并将采集到的信号数据保存到电子表格中(Save signal data acquisition and preservation of the signal, the default sampling rate is 10 times the signal frequency, and collected into a spreadsheet)

说明：  使用研华采集卡，labview驱动，采集数据和存储，曲线显示(Labview data acq excel save and display)

labview 钢琴程序，自定义控件+生产者消费者结构(labview piano program, custom+ producers and consumers Structure)

1．采用Labview设计一虚拟函数信号发生器， 通过数据采集卡输出波形信号，调节信号的相关参数，可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口； ⑵ 数据采集卡输出多种信号，至少完成三种波形：正弦波、三角波、方波(可调占空比)的输出，同时前面板上显示各输出波形； ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比（0～100 ）等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

此源程序为用Labview程序编制的，针对采集信号的功率进行分析。。(This source program is compiled by Labview program, and the power of the collected signals is analyzed..)
