# PWM Control Example
|
||||
#
|
||||
# This example shows how to do PWM with your OpenMV Cam.
|
||||
#
|
||||
# WARNING: PWM control is... not easy with MicroPython. You have to use
|
||||
# the correct timer with the correct pins and channels. As for what the
|
||||
# correct values are - who knows. If you need to change the pins from the
|
||||
# example below please try out different timer/channel/pin configs.
|
||||
|
||||
import pyb, time
|
||||
import time
|
||||
from pyb import Pin, Timer
|
||||
|
||||
t2 = pyb.Timer(1, freq=1000)
|
||||
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)
|
||||
|
||||
ch1 = t2.channel(2, pyb.Timer.PWM, pin=pyb.Pin("P0"))
|
||||
ch2 = t2.channel(3, pyb.Timer.PWM, pin=pyb.Pin("P1"))
|
||||
|
||||
while(True):
|
||||
for i in range(100):
|
||||
ch1.pulse_width_percent(i)
|
||||
ch2.pulse_width_percent(100-i)
|
||||
time.sleep(5)
|
||||
for i in range(100):
|
||||
ch1.pulse_width_percent(100-i)
|
||||
ch2.pulse_width_percent(i)

time.sleep(5)
