pulseio
--- Support for pulse based protocolsΒΆ
The pulseio
module contains classes to provide access to basic pulse IO.
Libraries
Warning
This module is not available in some SAMD21 builds. See the Support Matrix for more info.
All classes change hardware state and should be deinitialized when they
are no longer needed if the program continues after use. To do so, either
call deinit()
or use a context manager. See
Lifetime and ContextManagers for more info.
For example:
import pulseio
import time
from board import *
pwm = pulseio.PWMOut(D13)
pwm.duty_cycle = 2 ** 15
time.sleep(0.1)
This example will initialize the the device, set
duty_cycle
, and then sleep 0.1 seconds.
CircuitPython will automatically turn off the PWM when it resets all
hardware after program completion. Use deinit()
or a with
statement
to do it yourself.
