Updated Mar 11, 2021

Environment

Operating System

  • LabVIEW Real-Time (NI Linux Real-Time)
  • Windows

This article explain and guide how to control PXI Linux RT by using Visual Studio IDE and execute a DAQ example on Linux RT. The system structure would need a windows based computer with Microsoft Visual Studio installed to connect a NI Linux RT PXI system.

Setting up the Software Environment

Suggest Visual Studio 2017 or later.
  1. SSH to Linux RT
  2. Install compiler in Linux RT
    • Command opkg install packagegroup-core-buildessential-dev
  3. Install debug Tool in Linux RT
    • Command opkg install gdb

New Project in Visual Studio

  1. Open Visual Studio.
  2. Create new project.
    • Create a new project > Empty Project click Next, change Project name and Location (recommend in C:\).
  1. Connect to remote system.
    • Click Tools > Options..., select Cross Platform > Connection Manager and Add a new remote system.
  1. Import DAX example. Drag C code and header file into project. 
    1. C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage\Cont Acq-Int Clk\ContAcq-IntClk.c
    2. C:\Program Files (x86)\National Instruments\NI-DAQ\DAQmx ANSI C Dev\include\NIDAQmx.h
  1. Right click the project and choose Properties to set file path. 
    1. In Configuration Properties > VC++ Directories, change Include Directories to C:\Program Files (x86)\National Instruments\NI-DAQ\DAQmx ANSI C Dev\include.
  1. Add ;/usr/lib/x86_64-linux-gnu/libnidaqmx.so.1 after Additional Dependencies under Linker > Input.
  1. In Configuration Properties > General.
    1. Change Output Directory to \bin\$(Platform)\$(Configuration)\.
    2. Change Intermediate Directory to \obj\$(Platform)\$(Configuration)\.
  1. Click run button.
  2. If bump up an error window. It means debug tool couldn't navigate .out file in Linux RT. 
​​​​
  1. Try to modify Output Directory and Intermediate Directory like step 5c.
    1. Change Output Directory to bin\$(Platform)\$(Configuration)\.
    2. Change Intermediate Directory to obj\$(Platform)\$(Configuration)\.
