This release includes examples showing the use of NI-VISA in C and LabVIEW.
C examples are located in usr\share\doc\ni-visa\examples. Make files are provided that link to the necessary libraries.
By installing the NI-VISA LabVIEW support, LabVIEW examples will be located in the LabVIEW examples directory.
NI-VISA 2022 Q3 for Linux does not support 32-bit versions of LabVIEW.
The VISA user must have write access to the file that represents the USB device, which is typically somewhere in a subdirectory within /dev/bus/usb. If this is not the case, the USB device is not accessible by VISA (it will not be found using viFindRsrc and viOpen will fail). The default configuration on most systems is that the 'root' user has write access; however, no other user has this access.
There are a number of options that you can take to provide a non-root user access to a USB device.
