succd

A little daemon for monitoring the SEM. This is a temporary solution that runs on a BeagleBone Enhanced (succbone.lab) and SHOULD be replaced with a proper PLC/SCADA system and general process control in the future.

Features:

1. Monitors the state of the Pirani gauge via the BBE's builtin ADC.
2. Allows enabling/disabling the diffusion/roughing pumps (builtin controller always keeps them enabled).
3. Allows for simulating vent/pumpdown button presses.

Known issues

Sometimes the websocket doesn't connect. Refreshing the page a few times should fix it.
