from machine import PWM pwm = PWM(0, frequency=5000) # use PWM timer 0, with a frequency of 5KHz # create pwm channel on pin P12 with a duty cycle of 50% pwm_c = pwm.channel(0, pin='P12', duty_cycle=0.5) pwm_c.duty_cycle(0.3) # change the duty cycle to 30%
Create a PWM object. This sets up the timer to oscillate at the specified frequency. timer is an integer from 0 to 3. frequency is an integer from 1 Hz to 78 KHz.

frequency
Connect a PWM channel to a pin, setting the initial duty cycle. id is an integer from 0 to 7. pin is a string argument. duty_cycle is a keyword-only float argument, with values between 0 and 1. Returns an instance of PWMChannel.
