LabVIEW with Linux

These simple applications allow you to use LabPro for data collection and output control in the Linux operating system. LabPro must be connected to the Linux computer via a serial cable. Note: Linux supports use of a LabPro connected via the serial port only.

Two download options may exist:

Program - Download if you are running LabVIEW™ software and want to see the program and source code. Run the program, examine the code, make modifications, and/or customize.

Stand-alone Application - These are software programs (developed with LabVIEW software) that work with the Vernier LabPro. They contain all of the features and functionality as described above. To run, all you need is the free LabVIEW 6.1 Run-Time Engine installed on your computer.

* Requires the LabPro Toolkit to be installed.

User needs rights to serial port:

You will also need to make sure that you have access to the serial ports of the computer being used in order for the LabPro VIs to work. With Linux, not all users automatically have access to serial ports. The root user will need to provide this access. Here are the specifics of how we did this, to give you an idea of what is involved.

For COM1:

chmod a+rw /dev/ttyS0

For COM2:

chmod a+rw /dev/ttyS1

The above commands will make the serial ports world-readable and world-writable, so any user can access them.

Instructions for using source code:

Enter the following string at the command prompt:

tar -zxvf {filename}.tar.gz

This will create a folder at the same level as the archive file including all the VIs and sub VIs.
