CircuitPython[8] is an open source derivative of the MicroPython programming language targeted towards the student and beginner. 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.

CircuitPython is a full Python compiler and runtime 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 Adafruit compatible products as well as higher level libraries for beginners.[9]

CircuitPython is a fork of MicroPython, originally created by Damien George.[10] The MicroPython community continues to discuss[11] forks of MicroPython into variants such as CircuitPython.

CircuitPython is targeted to be compliant with CPython, the reference implementation of the Python programming language.[12] Programs written for CircuitPython compatible boards may not run unmodified on other platforms such as the Raspberry Pi.[13]

Usage

CircuitPython is currently being used for more projects, especially for wearable technology, when in the past the code may have been done in the Arduino development environment.[14] The language has also seen uptake in making small, handheld video game devices.[15] Developer Chris Young has ported his infrared receive/transmit software to CircuitPython to provide interactivity and to aid those with accessibility issues.[16]

Community

The user community support includes a Discord chat room and product support forums.[17] There is a published Code of Conduct for the project.[18]

For the general Python community, Adafruit has supported the Python Foundation for several years.[19][20][21]

CircuitPython support was incorporated into the Mu Python Editor.[22]

A Twitter account dedicated to CircuitPython news was established in 2018.[23]

Documentation

The Applications Programming Interface (API) is documented in Read the Docs.[24]

Tutorials on CircuitPython use, including introductory guides, are available on the Adafruit company learning system.[25]

Availability

The source code for the project is available on GitHub.[26]

The current stable version is 2.3.1[27] with support for the Microchip Technology Atmel SAMD21 processor[28] and the ESP8266 microcontroller. Adafruit has announced a major revision, 3.0.0, in alpha[29] with support for the SAMD51 series processor.[30]
