EDM Interface for Slope Box
The Raspberry Pi contains an EDM screen allowing users to read and write process variables (PVs). The Slope Box PVs include detector controls and monitoring (HV, Temps, etc.), and the SBX Pickoff PVs include control for signal processing functions (DC offset, gain range, Preamp Reset Clamping, etc.).
