With the interface now in place (DM-28775), the development of the CSC can begin. This epic is used to develop and write unit tests for version 1 of the CSC that will interact with the hardware/software of the camera and relay the appropriate information to the Rubin Control System. This will entail communication with the Leiden group to gather example datasets for the testing. It is expected that the use of an EFD will be required and therefore a series of tests may utilize either the Tucson test stand or NCSA test stand.
