# Bus- und Bahn-Anzeige (bus and train display)
|
|
|
|
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.
