Finally ported all the code both arduino and python code over to use the new LED I2C screen and uploaded it all to my GITHUB. I found a more affective way to transfuse/encoding the data from the raspberry pi to the atmega_screen. I rapped the necessary data with a #1 or #2 or #3 ect at the start and ; at the end then all the atmega_screen had to do was scan incoming serial data starting #1 and ending in ; ect. This has made it much easier to send the code to the atmega_screen
