Siemens DL2416T smart display

http://arduous.orcinus.me/ Quick test of a Siemens DL2416T smart display hooked up to an Arduino via a 74HC595 shift register. It's an old bubble-type segment LED display, with a starburst segment arrangement and built in decoder, RAM, ROM, character encoders etc. Communication is via a 7-bit data bus (ASCII character codes) and a 2-bit address bus (display position). It also has some other nifty features, like a PWM-able blanking pin, cursor support and two chip select lines (which enable you to stack up to 4 of these and control them with a single bus).
