I can get the motor to turn just fine when I use an Arduino Uno. If I run the same code on an Arduino Mega 2560 R3 and to the calibration it will Beep but the motor will not turn. Is there special UART setting I need order to use an Arduino Mega?
I used the actual Serial lines pin 18 &19 and that worked.
#define odrive_serial_1 Serial1 //s1 1 motor On Mega: 18 = TX (goes to RX on odrive), 19 = RX (goes to TX on odrive)
