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:

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

Accessing at the lab

Go to succbone.lab.fa-fo.de.

Known issues

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

Running locally

$ go run . -fake

Then point your browser to localhost:8080

Deploying on the succbone

$ ssh root@succbone systemctl stop succd
$ GOARCH=arm go build .
$ scp succd root@succbone:/usr/bin/succd
$ ssh root@succbone systemctl start succd
