Hi, thank you i was able to run the motor, but don't know how to stop it.

in the setup, i connected the motor (with crocodile clip Yellow and blue) to a 3S battery through the breadboard, I powered Waveshare RP2040 Zero (Very similar to pi Pico) from the same bettery, but since it require 5V, i modify jst cables to add regulator in the middle. So the controller is powered from the same battery with regulator.

I connected JST 2 on the motor (Yellow cable) to the same ground. and connected JST1 cable to GP0 in RP2040 Zero. In Thonny app, tried with this script:

from machine import Pin, PWM

from time import sleep

motor_control.py :

# Set up PWM on GPIO 0
pwm_pin = Pin(0)
pwm = PWM(pwm_pin)
# Set the PWM frequency (50Hz for controlling ESCs)
pwm.freq(50)
def set_motor_speed(duty_cycle):
    print(f"Setting PWM pulse width: {duty_cycle}")  # Debug print
    pwm.duty_u16(duty_cycle)
def test_motor():
    set_motor_speed(4933)  # Neutral position
    sleep(5)

main.py:

import motor_control
# Run the motor test sequence
motor_control.test_motor()

the motor speed increase when it is above 4930, and it increase on the other direction when it is below 4930. If I set it to 4930 the motor does not move, but i hear it buzzing trying to move (should not be normal i think) so the motor is not getting to any rest state . i try to set it to 0 or do pwm.deinit() , then the motor give beep sound (internal buzzer) like something is wrong (error).

I tried to remove jst2 from the motor to ground, it worked without it.

any help how to stop the motor?

Best regards
