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?
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.
Thank you for your reply.
I am using DIY board (arduino nano +servo board ) and using 24LC256 EEPROM. Battery is 2s lipo (350 25c)
What do you mean flip?
is it mean chnging negative to positive?
@北川 成人 It involves many aspects to make the robot work properly. It's hard to debug whether it's a hardware or software problem, if you are not using our official kit. Have you tested the testEEPROM.ino in the moduleTest folder?
