Hello,
recently I stumbled over the following article:
http://jeelabs.org/2015/04/01/emulating-eeprom/
Jean-Claude describes how to emulate EEPROM memory use Flash memory of LPC8xx µC. When reading this I remembered TinyG v9's problem that settings could not be stored since it does not have any EEPROM - perhaps this might be an idea to overcome this limitation.
Regards,
Roland
