I am just looking for some advise. I use the ATSAM3X8EA-AU on a custom PCB and a lot of the software is written using libraries specific to the Arduino due (ATSAM3X8EA-AU). My issue is that the ATSAM3X8EA-AU chip is being changed and will now have no i2C, so I would lose communication with my clock, EEPROM etc. when I use the new version of the chip.
I was wondering if anyone knew of another micro controller that could replace the ATSAM3X8EA-AU and provide all of its functionality (i2c etc) or could suggest an alternative that I could move to with that would involve the smallest amount of hardware / software changes.
Thanks in advance for the replies, I realize that this is an extremely complex question and will more than likely not have an easy answer but any advice that might point me in the right direction would be greatly appreciated.
