CircuitScheme - Lisp on CircuitPython

A new guide today in the Adafruit Learning System: CircuitScheme – Lisp on CircuitPython

The Microchip SAMD51 processor on the Adafruit Metro M4 Express, Feather M4 Express, ItsyBitsy M4, and Grand Central provides the speed and storage to enable programming in languages such as Lisp. Rather than running on the board “bare metal” like an Arduino port, CircuitScheme can draw on the underlying CircuitPython to provide strong Python constructs and access to the board capability.

This guide introduces an implementation of a Lisp dialect very similar to Scheme with an interesting feature: it’s written in Python 3. It’s called is CircuitScheme. The implementation is based on Lispy.py written some time ago by Peter Norvig who wrote the books Artificial Intelligence: A Modern Approach and Paradigms of AI Programming: Case Studies in Common Lisp . He is currently Director of Research at Google.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
