Introduction

This is a set of CircuitPython libraries to emulate most of the functionality in two of the BBC micro:bit's MicroPython libraries on an Adafruit CLUE. The CLUE is a more advanced derivative of the micro:bit with a full colour 240x240 LCD screen, a compatible edge connector, more sensors and a tiny onboard speaker.

This allows existing micro:bit code to run without modification on the CLUE. It also provides visualisation of any values read from or written to the GPIO pads/pins.

An earlier version of the library can be seen in the video: Adafruit CLUE running MicroPython code from Kitronik's Inventor's Kit using an emulation library (YouTube). The video features experiment 3 from Kitronik's Inventor's Kit for BBC micro:bit running on the Adafruit CLUE. The full set of MicroPython examples are replicated in this repository in examples/kitronik directory.

Dependencies

These libraries depend on:

Usage Example

The example below shows how the data from the pins is displayed in enhanced mode. The code ultimately outputs PWM audio on pad 0, reads an analogue voltage from pad 1 and writes that voltage to pad 2 as a PWM signal.

from microbit import *
import music

display.mode = "text"
display.scroll("Hello world...")
display.show(Image.HAPPY)
sleep(2000)
display.mode = "basic"
display.scroll("Basic mode...")
display.mode = "small"
display.show("Small mode!")
display.mode = "enhanced"
display.show("Enhanced = small + pins")
sleep(2000)
pin1.read_digital()
sleep(2000)
pin1.read_analog()
sleep(2000)
pin2.read_digital()
sleep(2000)
music.play(music.WAWAWAWAA, pin=speaker)
while True:
    if button_a.is_pressed():
        music.play(music.WAWAWAWAA)
    if button_b.is_pressed():
        pin2.write_analog(pin1.read_analog())
