Triport#
Initializing the Triport Class#
A Triport, or 3-Wire Expander, is created by using the following constructor:
Triport(port)
This constructor only uses one parameter:
Parameter |
Description |
|---|---|
|
The port the 3-Wire Expander is connected to on the EXP Brain. |
# 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.
