pyb
A Switch object is used to control a push-button switch.
Usage:
sw = pyb.Switch() # create a switch object
sw.value() # get state (True if pressed, False otherwise)
sw() # shorthand notation to get the switch state
sw.callback(f) # register a callback to be called when the
# switch is pressed down
sw.callback(None) # remove the callback
Example:
pyb.Switch().callback(lambda: pyb.LED(1).toggle())
Create and return a switch object.
Switch.__call__()
Call switch object directly to get its state: True
if pressed down, False
otherwise.
Switch.value()
Get the switch state. Returns True
if pressed down, otherwise False
.
Switch.callback(fun)
Register the given function to be called when the switch is pressed down. If fun
is None
, then it disables the callback.
