PCAN Basic LabVIEW

A lightweight wrapper for PCAN Basic API. This wrapper has been tested against version PCAN Basic API V4.10.1.968 with Peak Driver 8.20.0 (Linux), 4.6.4 (Windows x86/x64).

This project includes code for event driven read on linux rt from the LinuxRT-IPC project, licensed under Apache License 2.0.

VIPM

The vipm folder contains a VIPM package with the VIs necessary to interface the driver from LabVIEW.
It creates a PCAN Basic palette under Instrument I/O.

Prerequisites

• LabVIEW 2019 64 bit
• (Optional) LUnit Test Framework (LabVIEW 2020) – GitHub Repository

NI-RT Linux

• Download PCAN Basic for Linux
• Copy peak-linux-driver-8.20.0.tar.gz to /home/lvuser/ on real-time target using a FTP client or Webdav
• Enter following commands in terminal to build and install pcan linux driver on NI-RT Linux:

  cd /home/lvuser
  tar -xzf peak-linux-driver-8.20.0.tar.gz
  cd peak-linux-driver-8.20.0
  make clean
  make
  sudo make install
  sudo mkdir -p /lib/modules/$(uname -r)/misc
  sudo cp $(find /lib/modules/ -name "pcan.ko" | head -n 1) /lib/modules/$(uname -r)/misc/
  sudo find /lib/modules/ -name "pcan.ko" ! -path "/lib/modules/$(uname -r)/*" -exec rm {} \;
  sudo depmod -a
  sudo modprobe pcan

Note: Errors will appear during build. They arise from missing g++ on NI-RT Linux. You can ignore these.

Windows

• Install PCAN Driver 4.6.4 for Windows
• Download PCAN Basic API 4 for Windows
• From PCAN-Basic_4x.zip copy x86/PCANBasic.dll to /Windows/SysWOW64
• From PCAN-Basic_4x.zip copy x64/PCANBasic.dll to /Windows/System32
