When one device fails, this should not influence updates of the other devices. Thus, early return was the wrong strategy here. Instead, when communication with a device fails, skip the process data update and continue with the next device. |

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
$ ./ci.sh # run tests
$ 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
