CircuitPython [5] is an open-source derivative of the MicroPython programming language targeted toward students and beginners. Development of CircuitPython is supported by Adafruit Industries. It is a software implementation of the Python 3 programming language, written in C. [3] It has been ported to run on several modern microcontrollers.

Contents

CircuitPython consists of a Python compiler to bytecode and a runtime interpreter of that bytecode that runs on the microcontroller hardware. The user is presented with an interactive prompt (the REPL) to execute supported commands immediately. Included are a selection of core Python libraries. CircuitPython includes modules which give the programmer access to the low-level hardware of supported products as well as higher-level libraries for beginners. [6]

CircuitPython is a fork of MicroPython, originally created by Damien George. [7] The MicroPython community continues to discuss [8] forks of MicroPython into variants such as CircuitPython.

CircuitPython is targeted to be compliant with CPython, the reference implementation of the Python programming language. [9] Programs written for CircuitPython-compatible boards may not run unmodified on other platforms such as the Raspberry Pi. [10]

Usage

CircuitPython is being used as an emerging alternative solution for microcontroller programming, which is usually done in C, C++, or assembly. The language has also seen uptake in making small, handheld video game devices. [11] [ better source needed ] Developer Chris Young has ported his infrared transmit-and-receive software to CircuitPython to provide interactivity and to aid those with accessibility issues. [12]

Community

The user community support includes a Discord chat room and product support forums. [13] A Twitter account dedicated to CircuitPython news was established in 2018. [14] A newsletter, Python on Microcontrollers, is published weekly since 15 November, 2016 by Adafruit to provide news and information on CircuitPython, MicroPython, and Python on single board computers. [15] A Reddit subreddit, r/CircuitPython, provides news on CircuitPython and related news and projects and has about 4,300 members. [16]

Hardware support

The version 9.1.0 supports a range of architectures, called "ports": [17]

These ports are considered alpha and will have bugs and missing functionality:

Previous versions supported the ESP8266 microcontroller, but its support was dropped in version 4. [18]

Blinka Software Abstraction Layer

CircuitPython code may run on MicroPython or CPython using the Adafruit written Blinka compatibility layer. [19] It acts as a translation layer between CircuitPython code and underlying code. This allows CircuitPython code to run on many more devices including a wide range of single-board computers which are listed on circuitpython.org. [20] It is a pip installable Python library. The CircuitPython runtime is not used, as documented in the guide CircuitPython Libraries on Linux and Raspberry Pi. [21]

Modules (Libraries)

Adafruit has fostered a community which has contributed software libraries for more than 488 sensors and drivers. [22] [23]
