PWM

Constructors

PWM(unit[optional], “pin_name”[required])

Create a PWM object associated with the given pin name. This allows you to then write PWM signal on the pin.

• unit: unit ID of the hardware PWM, will use default unit 0 if leave blank

• 「pin_name」: The name of the pin, must be in string format. See below for PWM supported pins.

Note:

PWM is currently only supported on the following pins,

PA_23, PA_24, PA_25, PA_26

Methods

PWM.write(dutycycle_float[required])

This method will output a PWM signal with given duty cycle on the associated GPIO pin.

• dutycycle_float: a floating point duty cycle value, can be from 0.0 (0%) to 1.0 (100%)
