六维力传感器数据采集界面程序设计

本文以vs2010+qt 编程，安装qwt插件,设计界面如图所示，以正弦信号模拟传感器接收的数据，运行效果如下所示.
在这里插入图片描述
由于力传感器相关软件信号采集只能在ubuntu的Clion下，所以需要将相关文件复制拷贝到其项目中，需要的文件有：

其中moc_xx.cpp改成moc_xx.h, 将其在mywidget.cpp中引用，因为qt编译是用Qmake,而Clion是用Cmake, 如果没加会出现以下错误：
在这里插入图片描述
Q_OBJECT未定义，若将Q_OBJECT删掉，则QT基本的信号和槽功能不能实现：

所以必须加上上述文件moc_xx.h,

设计步骤:

参考我的基于vs2010+qt计算器设计界面，添加qwtplot控件，添加开始和结束按钮，分别命好名qwtPlot_X qwtPlot_Y qwtPlot_Z qwtPlot_RX qwtPlot_RY qwtPlot_RZ
添加click响应和自定义槽函数start()和finish()

运行即可出现界面
3.重新定义QWTPLOT属性

定义模拟信号的函数Getdata 和更新qwtplot_x的函数，其中updatadataSlot_X（）是实时显示动态曲线的关键

在start（）里添加connect(),连接信号和槽

此时运行可出现第一张图像
动态显示正弦曲线的相关代码
