guys, do you know how to write negative value on eeprom in a simple way? thx

Negative values are written the same way as any other values. It's all just bits, right?

There are code samples here: http://arduino.cc/en/Reference/EEPROM

Just cast it to an unsigned value:

char value = -121;
EEPROM.write(address,(byte)value);
value = (char) EEPROM.read(address);

Please don’t cross post.

Thanks,
