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 directory contains a number of documents about the device, all in German.

Character Set

The display uses 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.
