I am struggling with external eeprom. writeinstinct seems to be correctly uploarded. However servos move inconsistently every typing of "c". So, I cheked eeprom data via serial monitor.

data looks exactly same as instinct nybble except negative value. every negative value is converted to positive like as -45 to 211 (256-45 ?)

Is this normal or cause of inconsistent servos behavior?

Please help.
