pwm_set_duty([stream],duty);
stream – optional parameter specifying the stream defined in
#USE PWM.
duty – an int16 constant or variable specifying the new PWM
high time.
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.
All devices.

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%.
Nothing.
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
