Cube

The communication is working through I2C protocoll. The basic logic is very simple:

Display programmed smooth animations
If a frame (full 64 led values) received, display it
5 seconds timeout for the default state. (Currently displaying programmed animations)

Protocoll

Only listen, no call backs
valid format for a frame:

Key	Position:"Value"
Start key	0:"/" 1:"/" 2:"?" 3:"?"
Payload	4-68:"0...255"
End key	69:"," 70:"," 71:" " 72:" "

Hardware

Because most of the esp8266 boards are working with 3.3V and our Cube board is a regular ATMEGA328 with 5V, we need a voltage shifter. This is a basic schematic realized with a BSS138 MOSFET. Breakout boards are available on most popular sites. There are also esp8266 boards with 5V logic shifter already on board. In that case, you don't need this schematic. Just connect SDA and SCL.
