## Software
### Cube
The communication is working through I2C protocoll.
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: "//??<64 color values>,, "
## 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.
