Old bus display reverse engineered to work with a Raspberry PiMay 13, 2013

 

Dimitri, Frank, Kevin and Robin from Eectronique have sent in some details of a project that they have been working on. They had an old early 90′s LED matrix sign and wanted to make it work with a Raspberry Pi. The circuit layout is what you would expect from that era.

They retreived an old (1992 !) bus display (the thing that says the next stops on the buses). It was old: unknown protocol, unknown wiring, not fast at all...
