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.
Are you using our NyBoard our your DIY boards? When I was building DIY boards, I noticed some bit flipping if the power supply is unstable.
