PWM
class PWM – Pulse Width Modulation
Quick Usage Example
Constructors
class machine.PWM(timer, frequency)
Create a PWM object. This sets up the timer
to oscillate at the specified frequency
. timer
is an integer from 0 to 3. frequency
is an integer from 1 Hz to 78 KHz (this values can change in future upgrades).
Methods
pwm.channel(id, pin * , duty_cycle=0.5)
Connect a PWM channel to a pin, setting the initial duty cycle. id
is an integer from 0 to 7. pin
is a string argument. duty_cycle
is a keyword-only float argument, with values between 0 and 1. Returns an instance of PWMChannel
.
class PWMChannel — PWM channel
Methods
pwmchannel.duty_cycle(value)
Set the duty cycle for a PWM channel. value
is a float argument, with values between 0 and 1.
