Factory EEPROM Value
Hey guys. Is there a factory programmed EEPROM value on the LPC11UXX, or does it just come with random contents? I want my program to be able to determine if the EEPROM is blank or not so it can load default configuration values. Unfortunately I've overwritten the EEPROM on my board several times so I can't check it myself. Thanks!

You could put in a few fixed bytes in there if you put in a configuration file, so you cant find them you know it isn't there. 4 bytes already give a 1 in 4 billion chance of random bytes having that value.
I have no clue what the EEPROM value is as factory default. I would guess all zeros, or all ones, but if you can give a simple program that reads EEPROM and puts it on serial terminal I can run it, never done anything with the EEPROM of my LPC11u24.
Comment here, then you get a mail you have it :)
Just ran your program. I won't copy it here, since it is a kinda long list, but everything is zero :).
