class Pin – control I/O pins

A pin is the basic object to control I/O pins. It has methods to set the mode of the pin (input, output, etc) and methods to get and set the digital logic level. For analog control of a pin, see the ADC class.

Usage Model:


class pyb.Pin(id, ...)

Create a new Pin object associated with the id. If additional arguments are given, they are used to initialise the pin. See pin.init().



Get or set the digital logic level of the pin:

  • With no argument, return 0 or 1 depending on the logic level of the pin.
  • With value given, set the logic level of the pin. value can be anything that converts to a boolean. If it converts to True, the pin is set high, otherwise it is set low.

Returns the currently configured pull of the pin. The integer returned will match one of the allowed constants for the pull argument to the init function.
