MicroPython Device Drivers for BBC micro:bit

Introduction

This website presents a host of MicroPython drivers, all for the BBC micro:bit. It is an ever increasing collection. Each driver has been tested on the micro:bit V2 that is hooked up to the device the driver has been written to control.

The driver code contains basic error checking. However unlike the compiled code drivers written e.g. for the Arduino platform, catching and dealing with exceptions in this MicroPython driver collection is largely left to the user program. MicroPython is a compiled language and lengthy routines performing error checking that may never be used would seriously impact available Flash memory.

These drivers are free for you to copy, use and enjoy. While each driver has been extensively tested with the micro:bit interfaced to the device, there is no warranty and you use the code at your own risk.

Alphabetical Listing of Available Drivers

Following is an alphabetical list of the MicroPython device drivers written specifically for the micro:bit. Each driver webpage provides the code, a full description on how to connect the device to the micro:bit and full documentation on public methods including code examples.
