This repository contains the driver code and Midas frontend for the main experimental magnet PS. There are two different versions of this driver - one using LAN-GPIB to run the magnets and a second one which uses the EPICS interface provided by GFA. The respective CMake targets are:

expmag (LAN-GPIB)
expmag_epics (EPICS interface)

Requirements

Requires a Midas installation with the environment variable MIDASSYS pointing to the built Midas artifacts and headers.

Build

Clone this repository, enter the cloned directory, and then build via CMake.

cmake -S "$(pwd)" -B <directory-to-build-in> -DBUILD_FRONTENDS=ON
cmake --build <directory-to-build-in> --clean-first -- -j8

Run

<directory-to-build-in>/expmag_scfe -e <instrument-name>

Including in Custom Frontend

To include this driver in a custom frontend, you should ensure the environment variable MIDASSYS points to your system install and include a snippet in your CMakeLists.txt similar to the following:

# If the path to the expmag repository is outside of the frontend
# repository, you also need to provide a location for the expmag
# artifacts as a second argument to `add_subdirectory`
# e.g. `./device/expmag`
add_subdirectory(
    <path-to-expmag-repository>
)

default_expmag_frontend(
  Magnets_instr_scfe  # Target Name
  Magnets_instr       # Frontend Name
  16                  # Event ID
  4                   # Number of channels
)
