Hi,
I built a Calendar for the Arduboy. Sadly it is not finished yet. Two weeks were not enough time for me. You can go through all the dates but saving the notes to the eeprom is not implemented correctly.
Recently I found some time to work on my code. I think this will be the first and my final commit. The code was written so fast that it could be my worst ever
Writing and saving notes to EEPROM should work now.
