LinkIt Smart 7688 -[6]- Using MRAA PWM in Python

example : PWM

import mraa

pin = mraa.Pwm(18)      # initialize on GPIO18 (pin P26)

pin.period_ms(2)          # set PWM frequency to 500Hz (2ms period)

pin.enable(True)          # enable PWM output

pin.write(0.25)              # set duty cycle to 25%
