TWIDisplay: 8-digit LCD
The TWIDisplay 8-digit LCD is an easy to use 8-digit 14-segment transflective LCD display. Libraries for Arduino and avr-gcc are available onGitHub.
Only four wires are required for operation, one for power (runs on both 3.3V and 5V), one for ground, and two for the TWI protocol. To control a display like this, a dedicated controller chip is required.
