MEDM: Motif Editor and Display Manager

MEDM is a Motif graphical user interface for designing and implementing control screens, called displays, that consist of a collection of graphical objects that display and/or change the values of EPICS process variables. The supported objects include buttons, meters, sliders, text displays/entries, and graphs. It has two modes of operation, EDIT and EXECUTE. Displays are created and edited in EDIT mode, and they are run in EXECUTE mode.

MEDM is maintained at the APS.

Binaries

A prebuilt version of MEDM for WIN32 is available in the EPICS Win32 Extensions distribution. A Windows X Server such as Exceed is necessary to run MEDM and other Motif extensions on WIN32. See "MEDM Fonts for Exceed" above for instructions on installing the MEDM fonts in Exceed.

Required Software

MEDM requires that the Motif and X11 header files and libraries be available and that the X11 and MOTIF settings in CONFIG_SITE.<host_arch> be set correctly.

MEDM was originally designed to use the plotting capabilities of the commercial library XRT/graph for its graphing widgets. It can now also be built using SciPlot, included in the MEDM distribution, instead.

On recent versions of Ubuntu some of the fonts that MEDM needs may have to be installed manually, using
   $ apt-get install xfont-100dpi
or equivalent. This is in addition to the
   $ cat medmfonts.ali >> /usr/share/fonts/X11/misc/fonts.alias
that adds the font aliases (the medmfonts.ali file is available here).
