class Switch – switch object¶

A Switch object is used to control a push-button switch.

Usage:

sw = pyb.Switch() # create a switch object
sw() # get state (True if pressed, False otherwise)
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())

Constructors¶

class pyb.Switch¶: Create and return a switch object.

Methods¶

switch()¶: Return the switch state: True if pressed down, False otherwise.

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.
