NI-DAQmx可通过多种方式来帮助用户节省开发时间并提高数据采集应用的性能, 其中一种方式是提供仅需使用少量函数却可实现大部分功能的API。 事实上,用户只需学习本文介绍的10个函数,便可解决80%的数据采集应用问题。 返回顶部 了解详情 NI- DAQmx 入门 指南 ...
The ADC is able to perform a conversion off virtually any clock signal, including variable frequency or nonperiodic signals, up to the maximum rate supported by the device. NI devices in this class provide flexible timing engines capable of driving the convert line on their ADCs from a variety...
像素最大最小值(Min and Max PixelValues) 在深度流中,通常知道一个像素可能出现的最大值和最小值是很有用的。用getMinPixelValue()和getMaxPixleValue()方法就能获取这些信息。 配置视频流 视频模式(Video Mode) 可以设置给定流的帧率(frame rate),分辨率(resolution)和像素格式(pixel type)。设置这些就要用到...
Baud rate, data bits,stop bits和parity等设置通讯参数。 2. Serial port write VI模块把String to write中的数据写到port number指定的 串行接口中。 3. Serial port read VI模块从Port number指定的串行接口中读取requested byte count指定的字符个数。 4. Bytes at serial port VI模块计算由Port number指定...
获取深度视频流需要使用4个主要的类(class)。 1. openni::OpenNI提供了一个静态的API进入点。它提供访问设备,设备相关事件,版本和错误信息。当然,首先得确保你连接了设备。 2. openni::Device提供了一个传感器设备连接系统的接口(个人理解就是通过Device类来访问控制传感器)。在它创建之前需要对OpenNI类进行初始化...

Property Class XNET Session Property ID nxPropSession_IntfBaudRate64 Description Note You can modify this property only when the interface is stopped. Note This property replaces the former 32-bit property. You still can use the baud rate values used with the 32-bit property. The custom 64-...
This offers specialized functionality such as multirate sampling and individual channel triggering, which are beyond the capabilities of typical data acquisition hardware. You can sample every analog input channel on an R Series device simultaneously at rates up to 750 kHz, and you can program...
