# Construct a Triport object named expander_1 in Port 1.
expander_1 = Triport(Ports.PORT1)
This expander_1 object will be used in all subsequent examples throughout this API documentation when referring to Triport class methods.
Triports also have a letter attribute denoting the specific port in use. Each port is identified by a letter (a through h) and can be accessed using the format expander_1.x, where x is the port letter. For example, expander_1.a refers to the Sensor connected to the Triport’s port A.
类方法#
index()#
The index() method returns the index of the Triport.
**返回：**三端口的索引。
installed()#
The installed() method checks if the Triport is connected.
Returns: True if the Triport is connected. False if it not.
timestamp()#
The timestamp() method returns the timestamp of the last received status packet from the Triport’s sensor.
**返回：**从 Triport 传感器接收到的最后一个状态包的时间戳（以毫秒为单位）。
