What is Charlieplexed LED Display Design Guide about?

This document describes a charlieplexed display circuit with 12 LEDs controlled using 4 pins. It uses D flip-flops to store user input from switches. Multiplexers select the LED for each state, controlled by a finite state machine (FSM). The FSM cycles through 12 states, each providing control signals to turn on one LED by selecting the multiplexer inputs and enabling the tristate buffers.
