调用方式 

高级别调用，面向对象方式，通过EV3BrickClient和Device对象进行操作： 

from lelink.conn.wificonnection import *
from lelink.ev3client import *

conn = WifiConnect()
conn.connect()

client = EV3BrickClient()
client.connect(conn)

motor = client.get_outputdevice(OutputPort.A)
motor.start_on_power(100)

低级别调用，面向过程方式，直接执行具体操作（或命令） 

from lelink.conn.wificonnection import *
from lelink.ev3command import *
from lelink.ev3operation import *

conn = WifiConnection()
conn.connect()

power_op = EV3OutputOpFactory.op_output_power(
                Layer.L0,
                { OutputPort.A },
                50)
start_op = EV3OutputOpFactory.op_output_start(
                Layer.L0,
                { OutputPort.A } )
cmd = EV3DirectCommand({power_op, start_op})
conn.send(cmd)
