We connected the motor for a drill to pin 6. I can turn the motor on or off by setting the pin high or low, but now we’d like to use PWM to control it. When I use the following example code, nothing happens:
from pyb import Pin, Timer
p = Pin(‘P6’)
tim = Timer(2, freq=10)
ch = tim.channel(1, Timer.PWM, pin=p)
ch.pulse_width_percent(50)
# PWM Control Example
#
# This example shows how to do PWM with your OpenMV Cam.
import time
from pyb import Pin, Timer
tim = Timer(4, freq=1000) # Frequency in Hz
# Generate a 1KHz square wave on TIM4 with 50% and 75% duty cycles on channels 1 and 2, respectively.
ch1 = tim.channel(1, Timer.PWM, pin=Pin("P7"), pulse_width_percent=50)
ch2 = tim.channel(2, Timer.PWM, pin=Pin("P8"), pulse_width_percent=75)
while (True):
time.sleep(1000)
