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.

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 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]

Hardware Support

The version 6.2.0 supports Atmel SAMD21 and SAMD51 microcontrollers from Microchip Technology,[15] nRF52833 and nRF52840 from Nordic Semiconductor, CXD5602 (Spresense) from Sony, and STM32 F4-series from STMicroelectronics.[2] Previous versions supported the ESP8266 microcontroller, but its support was dropped in version 4.[16]
