motor does not reply #7

Open jfl21 opened 1 year ago

jfl21 commented 1 year ago

Hellow! I tried to control A1 motor with Raspberry Pi 4b(ubuntu 20.04). But when I ran the "motorctrl", the following information is continuously printed:

" [WARNING] SerialPort::recv, unblock version, wait time out [WARNING] motor id=2 does not reply

motor.Pos: 0 motor.Temp: 0 motor.W: 7.06952e-10 motor.T: 7.93298e+34 motor.MError: 1986356271 "

Because I don't know the exact motor id, I tried "motor id = 0, 1, 2, or 0xBB". These situation all showed similar errors and the motor didn't work. So, I wonder what the problem is and how I can solve it.

Thanks for reply. I have solved the problem. The sequence of line which bought together from the motos is wrong. We adjust the line sequence then the motor works well.
