PWM.
duty – an int16 constant or variable specifying the new PWM high time.
Returns:
Function:
Nothing.
To change the duty cycle of the PWM signal. The duty cycle
percentage depends on the period of the PWM signal. This function is
faster than pwm_set_duty_percent(), but requires you to know what the
period of the PWM signal is.
Availability: All devices.
Requires:

#USE PWM
#USE PWM(OUTPUT=PIN_C2, FREQUENCY=10kHz, DUTY=25)
None
#use_pwm, pwm_on, pwm_off(), pwm_set_frequency(),
pwm_set_duty_percent()
pwm_set_duty_percent
Syntax:
pwm_set_duty_percent([stream]), percent
Parameters: stream – optional parameter specifying the stream defined in #USE PWM.
percent- an int16 constant or variable ranging from 0 to 1000 specifying the new PWM duty
cycle, D is 0% and 1000 is 100.0%.

To change the duty cycle of the PWM signal. Duty cycle percentage is based off the current
frequency/period of the PWM signal.
All devices.
#USE PWM
#USE PWM(OUTPUT=PIN_C2, FREQUENCY=10kHz, DUTY=25)
pwm_set_duty_percent(500); //set PWM duty cycle to 50%
None
#use_pwm, pwm_on(), pwm_off(), pwm_set_frequency(),
pwm_set_duty()
pwm_set_frequency
Syntax:
pwm_set_frequency([stream],frequency);
Parameters: stream – optional parameter specifying the stream defined in #USE
PWM.
frequency – an int32 constant or variable specifying the new PWM
frequency.
