What is Roc-MQTT-Display?

It's a dynamic Passenger Information system for Model Railroad Stations controlled by Rocrail. Communicates with Rocrail via MQTT messages. A Lolin/Wemos D1 mini ESP8266 controller and a TCA9548A I2C Multiplexer can drive up to eight 0.91" 128x32 I2C OLED displays. Several D1 mini controllers can run together so the total number of displays is not limited. The goal was to create an easy to integrate, non expensive, scalable and flexible system of displays for model railroad systems.
