+Portation from AVR Mega 2560 to SAM3X8E (Arduino DUE) and ESP not completed yet and on early stage now.
+Core is mostly migrated (except EEPROM in DUE)
+
+AVR version is basic and have all functions
+
+Another platforms limitations (todo):
+SAM3X8E:
+-EEPROM issues to be fixed
+-DMX-in - not deployed yet
+-Improve http client
+
+ESP:
+-Wifi instead Ether not implemented yet
+-DMX-IN
