i was wondering if there was a way to write to the Arduino EEPROM directly. I would like to design a shield of some sort that could edit the EEPROM without the need to load another program onto the chip.
A bit like the famous tinyG-shield that takes over your arduino. Whatever sketch you have on your arduino is left there. The ports are hijacked.
I would love to know if this was at all possible with the MEGA.
Thanks for your suggestions.
