cpgame

Simple "game" framework for CircuitPython embedded hardware.

Install

Download the compiled library and copy it to your device's directory:

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

Overview

cpgame provides a number of decorators and a simple event loop to provide a responsive framework for building applications and games on embedded hardware using CircuitPython.

Run a function on every "tick" of the event loop:

from cpgame import start, tick

@tick
def loop(now):
    ...

start()

Blink a Neopixel every second:

@every(1)
def periodic(now):
    pixel[0] = RED if int(now) % 2 else OFF

Turn a Neopixel on and off with a button press:

@on(board.BUTTON_A, DOWN)
def pressed(now):
    pixel[0] = RED

@on(board.BUTTON_A, UP)
def released(now):
    pixel[0] = OFF

Create or reset timers:

@on(board.BUTTON_A)
def flood(now):
    pixels.fill(random.choice(COLORS))
    delay = random.randint(20, 100) / 10  # between 2 and 10 seconds
    after(delay, flood)

@on(board.BUTTON_B)
def halt(now):
    cancel(flood)

Play sound:

enable_speaker()
middle_a = sample(440)

@on(board.BUTTON_A)
def noise(now):
    play_sound(middle_a, 1)

Roadmap

• Support more boards than Circuit Playground Express.
• Add helper functions for animating NeoPixels, raw audio clips, and LCD displays.
