Angle-Servo Moves but Continuous servo motor doesn't move

[mhaboali]

Describe the issue I have one servo motor is connected to the first channel and another continuous motor is connected to channel 2 to the pca_9685

I've set up this library on my Jetson Xavier Nx and I managed to command an angle-servo motor but when I've commanded a continuous servo motor, it didn't move.

NVIDIA Jetson Hardware

• [ X] Jetson Xavier Nx.

I"ve used this code

from adafruit_servokit import ServoKit
import board
import busio
import time
print("Initializing Servos")
Initializing Servos
i2c_bus0=(busio.I2C(board.SCL_1, board.SDA_1))
print("Initializing ServoKit")
Initializing ServoKit
kit = ServoKit(channels=16, address=0x41, i2c=i2c_bus0)

And when use this kit.servo[0].angle=30 the motor moves but when use this command kit.continuous_servo[1].throttle=0.5 the motor doesn't move.

Any help, please?

are you following a youtuber video? if so please ask them for support with their tutorial series

No, I just followed the PythonCircuit tutorial on Adafruit tutorials.

This one is a bit old, but just tested and can not recreate. Closing for now.

With a continuous rotation servo attached to output channel 1 of a PCA9685 breakout running the following code:

Adafruit CircuitPython 7.2.5 on 2022-04-06; Adafruit QT Py M0 with samd21e18
>>> from adafruit_servokit import ServoKit
>>> kit = ServoKit(channels=16)
>>> kit.continuous_servo[1].throttle = 0
>>> kit.continuous_servo[1].throttle = 0.1
>>> kit.continuous_servo[1].throttle = 0.2
>>> kit.continuous_servo[1].throttle = 0.5
>>> kit.continuous_servo[1].throttle = 1
>>>  

servo behaves as expected.
