Objects In Python

Interface to Objects In Space for CircuitPython embedded hardware.

Install

Download the compiled module and copy them to your board. Note there are two versions: "full" or regular for boards with more memory (eg, M4/samd51) and "tiny" for boards with less memory (eg, M0/samd21). When using the tiny build, be sure to rename the module to oip.mpy.

$ cp -X oip.mpy /Volumes/CIRCUITPY/oip.mpy

OR

$ cp -X oip-tiny.mpy /Volumes/CIRCUITPY/oip.mpy

Overview

Objects In Python uses a simple, event-based API to execute your functions when buttons are pressed or game values update. Getting started is as easy as importing the module, creating the interface, and starting the connection:

from oip import OIP

oip = OIP()
...
oip.start()

Turn lights on or off when game state changes:

@oip.on("IFF_ACTIVE")
def iff_active(now, value):
    pixels[0] = BLUE if value else RED

Connect buttons to game commands:

@oip.press(board.BUTTON_A)
def thrust_while_holding(now, value):
    oip.execute("BURN_MAIN_ENGINE" if value else "STOP_MAIN_ENGINE")

With the full build, use helper classes to mitigate typoes:

@oip.on(Boolean.IFF_ACTIVE)
def iff_active(now, value):
    ...

@oip.press(board.BUTTON_A)
def thrust_while_holding(now, value):
    oip.execute(Command.BURN_MAIN_ENGINE if value else Command.STOP_MAIN_ENGINE)
