This is the code to send information to the station display that is hangin in the hallway of CCCHH. This is the code to send information to the station display that is hanging in the hallway of CCCHH.
## Documentation
The [docs](./docs) directory contains a number of documents about the device, all in German.
## Character Set
The display uses [Code Page 437](https://en.wikipedia.org/wiki/Code_page_437), with a few exceptions. Due to the limited
resolution of the segments, the display can deviate significantly.
| Code | CP437 | Geavision Spaltenschrift |
|------|--------------|--------------------------|
| 0xb4 | ┤ u2524 | Vehicle end left |
| 0xb5 | ╡ u2561 | Vehicle end right |
| 0xb6 | ╢ u2562 | Track |
| 0xff |   u00a0 | Three full segments |
In other displays, the vehicle ends can be used together with other special characters to show carriage information;
this set seems to be missing those extra characters.
