PWM Class

Constructor

Creates and initializes a PWM (Pulse Width Modulation) to output PWM signals.

pwm0 = PWM(board, Pin(board, Pin.D6))
  • board: The board object created by the PinPong class. This parameter can be omitted if there is only one board.
  • Pin: The pin object created by the Pin class.

Methods

pwm0.freq() freq(), When called with no arguments, it returns the frequency. f = pwm0.freq() # Get the PWM frequency pwm0.freq(x) freq(x), When called with an argument, it sets the PWM frequency to x. pwm0.freq(1000) # Set the PWM frequency to 1000 
pwm0.duty() duty(), When called with no arguments, it returns the duty cycle. f = pwm0.duty() # Get the PWM duty cycle pwm0.duty(x) duty(x), When called with an argument, it sets the PWM duty cycle, the range is 0-255. pwm0.duty(127) # Set the PWM duty cycle to 50% 
pwm0.deinit()
