Overview
There is a giant LED sign at the shop. I am very lazy so I am not going to tell you what kind it is. However, I do know that the python library for Alpha American and Betabrite signs will drive it just fine.
Old versions:
- LED Sign/v1
- LED Sign/v2 (current production)
Goals for this version
- Be completely driven from mqtt.
- Split out the logic into two parts: the display part, and any "processing" tasks.
- For instance, pushing a message to a certain screen will be done by publishing to the correct mqtt endpoint. But the sign will not listen to any endpoints except its own - an external app will have to, for instance, listen to CasCADE messages and publish them to the sign in a modified form.
- Support "signcode" (formatting instructions like {green}).
- Run on a Raspberry Pi so it can be physically contained in the sign itself.
