ImGuiDM

WORK IN PROGRESS

EPICS Display Manager based on Dear ImGui

Currently uses the EPICS example app which defines a circle. So if you start the ioc that provides $USER:circle:angle, $USER:circle:x, $USER:circle:y, etc. you should see those values in the gui.

Useful:

git clone ...
cd imguiDM
git submodule update --init --recursive
mkdir build && cd build
cmake ../.
make
make install
imgui_dm

The demo will search and timeout while it waits for some PV channels to open.
If you have the example IOC running it will start up fast because it will find them.

Process Variables

The handling of PV is very much a work in progress. Currently the PVGetList class (in src/epics) will take a list of PVs and try to connect to them. If they are connected, their current values are read and cached. There is also a buffer which is filled everytime the memeber function Poll() is called. This saves a history (for plotting a real time strip chart).

TODO: On initialization look up the history from an archiver if it exists, and fill the PV buffer.
