PVAccess for LabVIEW

An EPICS PVAccess library for LabVIEW.

⚠️ This software is in the alpha stage of development and does not have a stable interface.

Requirements

The VIPM package is compatible with LabVIEW 2020 or above.

Real-time targets running NI Linux RT 2023 Q1 or above should be compatible.

Installation

LabVIEW library (VIPM)

Download the latest .vip file from releases and open it with VIPM.

NI Linux Real-Time

SSH into the target and run this command, replace <VERSION>with the version of the VIP file you have installed.

wget https://github.com/ISISNeutronMuon/pvaccess-labview/releases/download/v<VERSION>/pva_labview_<VERSION>.ipk
opkg install pva_labview_<VERSION>.ipk

Development

Prerequisits

Windows

• Install the Microsoft C++ Build Tools

• Install Chocolatey

• Install Make, CMake and Perl

  choco install make cmake strawberryperl

• Launch the "Developer Command Prompt for VS", not PowerShell, and run the subsequent commands from it

• Activate the 64-bit environment

Linux

• Install Make, CMake, Perl and libevent using your distribution's package manager

  sudo apt install make cmake perl libevent-dev

Building dependencies

Windows

• Build EPICS Base

  set EPICS_HOST_ARCH=windows-x64-static
  make -C epics-base

• Build PVXS

  echo EPICS_BASE = $(TOP)/../epics-base > pvxs/configure/RELEASE.local
  make -C pvxs/bundle libevent
  make -C pvxs

  See the PVXS docs for more details

Linux

• Build EPICS Base

  make -C epics-base

• Build PVXS

  cat <<EOF > pvxs/configure/RELEASE.local
  EPICS_BASE = \$(TOP)/../epics-base
  EOF
  make -C pvxs

Building this library

• Windows

  cmake --preset=windows-x64
  cmake --build --preset=windows-x64

• Linux

  cmake --preset=linux-x86_64
