Classes such as :py:class:`ev3dev2.motor.Motor` and those based on :py:class:`ev3dev2.sensor.Sensor` accept parameters to specify which port the target device is connected to. This parameter is typically caled address.

The following constants are available on all platforms:

Output

• ev3dev2.motor.OUTPUT_A
• ev3dev2.motor.OUTPUT_B
• ev3dev2.motor.OUTPUT_C
• ev3dev2.motor.OUTPUT_D

Input

• ev3dev2.sensor.INPUT_1
• ev3dev2.sensor.INPUT_2
• ev3dev2.sensor.INPUT_3
• ev3dev2.sensor.INPUT_4

Additionally, on BrickPi3, the ports of up to four stacked BrickPi's can be referenced as OUTPUT_E through OUTPUT_P and INPUT_5 through INPUT_16.

Example

from ev3dev2.motor import LargeMotor, OUTPUT_A, OUTPUT_B
from ev3dev2.sensor import INPUT_1
from ev3dev2.sensor.lego import TouchSensor

m = LargeMotor(OUTPUT_A)
s = TouchSensor(INPUT_1)
