Public Instance Methods
get_identity()
click to toggle source
Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.
The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an :ref:`Isolator Bricklet <isolator_bricklet>` is always at position 'z'.
The device identifier numbers can be found :ref:`here <device_identifier>`. |device_identifier_constant|
