This backend allows to access EPICS process variables via EPICS channel access. It was tested with EPICS R7.0.5.
In order to use this backend add device to your device mapping file using the following syntax:
Test (epics:?map=epics.map)
The specified mapping file epics.map includes the names of the EPICS channels to be accessed in combination with an register path to be used in ChimeraTK:
#epics.map
epics_data/testArray test:compressExample
In the above example the EPICS channel test:compressExample will be mapped to the ChimeraTK register path epics_data/testArray.
Using the submodule structure is posible but not necessary. E.g. one could also just assign the register path testArray.
If you have not installed EPICS in a standard install directory pass the EPICS path to cmake using:
-DEPICS_BASE_DIR=PATH_TO_EPICS.
