Anybody had any experience connecting this display to a UNO? It is a dual 14-segment display but has just 4 connections to the outside world, +V, ground, serial data and clock, and is the same physical size as a standard dual LED display, the electronics built in to the LED case!
I want to replace the existing piece of equipment that drives it with a UNO board, connecting it with a 4-core cable.
There is a lot of info using shift-registers and common anode/cathode displays but using 5-wires, and a number of different libraries.
Anyone got any ideas.
